Not only is this method rarely used, there are few good reasons to use intersections at all.

It now behaves identically to `.int()` (see below). Importantly, that means it no longer accepts floats. + +### `.int()` accepts safe integers only + +The `z.number().int()` API no longer accepts unsafe integers (outside the range of `Number.MIN_SAFE_INTEGER` and `Number.MAX_SAFE_INTEGER`). Using integers out of this range causes spontaneous rounding errors. (Also: You should switch to `z.int()`.) + +## `z.string()` updates + +### deprecates `.email()` etc + +String formats are now represented as *subclasses* of `ZodString`, instead of simple internal refinements. As such, these APIs have been moved to the top-level `z` namespace. Top-level APIs are also less verbose and more tree-shakable. + +```ts +z.email(); +z.uuid(); +z.url(); +z.emoji(); // validates a single emoji character +z.base64(); +z.base64url(); +z.nanoid(); +z.cuid(); +z.cuid2(); +z.ulid(); +z.ipv4(); +z.ipv6(); +z.cidrv4(); // ip range +z.cidrv6(); // ip range +z.iso.date(); +z.iso.time(); +z.iso.datetime(); +z.iso.duration(); +``` + +The method forms (`z.string().email()`) still exist and work as before, but are now deprecated. + +```ts +z.string().email(); // ❌ deprecated +z.email(); // ✅ +``` + + +### no padding in `.base64url()` + +Padding is no longer allowed in `z.base64url()` (formerly `z.string().base64url()`). Generally it's desirable for base64url strings to be unpadded and URL-safe. + +### drops `z.string().ip()` + +This has been replaced with separate `.ipv4()` and `.ipv6()` methods. Use `z.union()` to combine them if you need to accept both. + +```ts +z.string().ip() // ❌ +z.ipv4() // ✅ +z.ipv6() // ✅ +``` + +### updates `z.string().ipv6()` + +Validation now happens using the `new URL()` constructor, which is far more robust than the old regular expression approach. Some invalid values that passed validation previously may now fail. + +### drops `z.string().cidr()` + +Similarly, this has been replaced with separate `.cidrv4()` and `.cidrv6()` methods. Use `z.union()` to combine them if you need to accept both. + +```ts +z.string().cidr() // ❌ +z.cidrv4() // ✅ +z.cidrv6() // ✅ +``` + +## `z.coerce` updates + +The input type of all coerced booleans is now `unknown`. + +```ts +const schema = z.coerce.string(); +type schemaInput = z.input; + +// Zod 3: string; +// Zod 4: unknown; +``` + +## `.default()` updates + +The application of `.default()` has changed in a subtle way. If the input is `undefined`, `ZodDefault` short-circuits the parsing process and returns the default value. The the default value must be assignable to the *output type*. + +```ts +const schema = z.string() + .transform(val => val.length) + .default(0); // should be a number +schema.parse(undefined); // => 0 +``` + +In Zod 3, `.default()` expected a value that matched the *input type*. `ZodDefault` would parse the default value, instead of short-circuiting. As such, the default value must be assignable to the *input type* of the schema. + +```ts +// Zod 3 +const schema = z.string() + .transform(val => val.length) + .default("tuna"); +schema.parse(undefined); // => 4 +``` + +To replicate the old behavior, Zod implements a new `.prefault()` API. This is short for "pre-parse default". + +```ts +// Zod 3 +const schema = z.string() + .transform(val => val.length) + .prefault("tuna"); +schema.parse(undefined); // => 4 +``` + + +## `z.object()` + +These modifier methods on the `ZodObject` class determine how the schema handles unknown keys. In Zod 4, this functionality now exists in top-level functions. This aligns better with Zod's declarative-first philosophy, and puts all object variants on equal footing. + + +### deprecates `.strict()` and `.passthrough()` + +These methods are generally no longer necessary. Instead use the top-level `z.strictObject()` and `z.looseObject()` functions. + +```ts +// Zod 3 +z.object({ name: z.string() }).strict(); +z.object({ name: z.string() }).passthrough(); + +// Zod 4 +z.strictObject({ name: z.string() }); +z.looseObject({ name: z.string() }); +``` + +> These methods are still available for backwards compatibility, and they will not be removed. They are considered legacy. + +### deprecates `.strip()` + +This was never particularly useful, as it was the default behavior of `z.object()`. To convert a strict object to a "regular" one, use `z.object(A.shape)`. + +### drops `.nonstrict()` + +This long-deprecated alias for `.strip()` has been removed. + +### drops `.deepPartial()` + +This has been long deprecated in Zod 3 and it now removed in Zod 4. There is no direct alternative to this API. There were lots of footguns in its implementation, and its use is generally an anti-pattern. + +### changes `z.unknown()` optionality + +The `z.unknown()` and `z.any()` types are no longer marked as "key optional" in the inferred types. + +```ts +const mySchema = z.object({ + a: z.any(), + b: z.unknown() +}); +// Zod 3: { a?: any; b?: unknown }; +// Zod 4: { a: any; b: unknown }; +``` + +## `z.nativeEnum()` deprecated + +The `z.nativeEnum()` function is now deprecated in favor of just `z.enum()`. The `z.enum()` API has been overloaded to support an enum-like input. + +```ts +enum Color { + Red = "red", + Green = "green", + Blue = "blue", +} + +const ColorSchema = z.enum(Color); // ✅ +``` + +As part of this refactor of `ZodEnum`, a number of long-deprecated and redundant features have been removed. These were all identical and only existed for historical reasons. + +```ts +ColorSchema.enum.Red; // ✅ => "Red" (canonical API) +ColorSchema.Enum.Red; // ❌ removed +ColorSchema.Values.Red; // ❌ removed +``` + +## `z.array()` + +### changes `.nonempty()` type + +This now behaves identically to `z.array().min(1)`. The inferred type does not change. + +```ts +const NonEmpty = z.array(z.string()).nonempty(); + +type NonEmpty = z.infer; +// Zod 3: [string, ...string[]] +// Zod 4: string[] +``` + +The old behavior is now better represented with `z.tuple()` and a "rest" argument. This aligns more closely to TypeScript's type system. + +```ts +z.tuple([z.string()], z.string()); +// => [string, ...string[]] +``` + +## `z.promise()` deprecated + +There's rarely a reason to use `z.promise()`. If you have an input that may be a `Promise`, just `await` it before parsing it with Zod. + +> If you are using `z.promise` to define an async function with `z.function()`, that's no longer necessary either; see the [`ZodFunction`](#function) section below. + +## `z.function()` + +The result of `z.function()` is no longer a Zod schema. Instead, it acts as a standalone "function factory" for defining Zod-validated functions. The API has also changed; you define an `input` and `output` schema upfront, instead of using `args()` and `.returns()` methods. + + + +```ts +const myFunction = z.function({ + input: [z.object({ + name: z.string(), + age: z.number().int(), + })], + output: z.string(), +}); + +myFunction.implement((input) => { + return `Hello ${input.name}, you are ${input.age} years old.`; +}); +``` + + +```ts +const myFunction = z.function() + .args(z.object({ + name: z.string(), + age: z.number().int(), + })) + .returns(z.string()); + +myFunction.implement((input) => { + return `Hello ${input.name}, you are ${input.age} years old.`; +}); +``` + + + +If you have a desperate need for a Zod schema with a function type, consider [this workaround](https://github.com/colinhacks/zod/issues/4143#issuecomment-2845134912). + +### adds `.implementAsync()` + +To define an async function, use `implementAsync()` instead of `implement()`. + +```ts +myFunction.implementAsync(async (input) => { + return `Hello ${input.name}, you are ${input.age} years old.`; +}); +``` + +## `.refine()` + +### ignores type predicates + +In Zod 3, passing a [type predicate](https://www.typescriptlang.org/docs/handbook/2/narrowing.html#using-type-predicates) as a refinement functions could still narrow the type of a schema. This wasn't documented but was discussed in some issues. This is no longer the case. + +```ts +const mySchema = z.unknown().refine((val): val is string => { + return typeof val === "string" +}); + +type MySchema = z.infer; +// Zod 3: `string` +// Zod 4: still `unknown` +``` + +### drops `ctx.path` + +Zod's new parsing architecture does not eagerly evaluate the `path` array. This was a necessary change that unlocks Zod 4's dramatic performance improvements. + +```ts +z.string().superRefine((val, ctx) => { + ctx.path; // ❌ no longer available +}); +``` + +### drops function as second argument + +The following horrifying overload has been removed. + +```ts +const longString = z.string().refine( + (val) => val.length > 10, + (val) => ({ message: `${val} is not more than 10 characters` }) +); +``` + +## `z.ostring()`, etc dropped + +The undocumented convenience methods `z.ostring()`, `z.onumber()`, etc. have been removed. These were shorthand methods for defining optional string schemas. + +## `z.literal()` + +### drops `symbol` support + +Symbols aren't considered literal values, nor can they be simply compared with `===`. This was an oversight in Zod 3. + +## static `.create()` factories dropped + +Previously all Zod classes defined a static `.create()` method. These are now implemented as standalone factory functions. + +```ts +z.ZodString.create(); // ❌ +``` + +## `z.record()` + +### drops single argument usage + +Before, `z.record()` could be used with a single argument. This is no longer supported. + +```ts +// Zod 3 +z.record(z.string()); // ✅ + +// Zod 4 +z.record(z.string()); // ❌ +z.record(z.string(), z.string()); // ✅ +``` + +### improves enum support + +Records have gotten a lot smarter. In Zod 3, passing an enum into `z.record()` as a key schema would result in a partial type + +```ts +const myRecord = z.record(z.enum(["a", "b", "c"]), z.number()); +// { a?: number; b?: number; c?: number; } +``` + +In Zod 4, this is no longer the case. The inferred type is what you'd expect, and Zod ensures exhaustiveness; that is, it makes sure all enum keys exist in the input during parsing. + +```ts +const myRecord = z.record(z.enum(["a", "b", "c"]), z.number()); +// { a: number; b: number; c: number; } +``` + +## `z.intersection()` + + +### throws `Error` on merge conflict + +Zod intersection parses the input against two schemas, then attempts to merge the results. In Zod 3, when the results were unmergable, Zod threw a `ZodError` with a special `"invalid_intersection_types"` issue. + +In Zod 4, this will throw a regular `Error` instead. The existence of unmergable results indicates a structural problem with the schema: an intersection of two incompatible types. Thus, a regular error is more appropriate than a validation error. + + + + + + + + + + + + + + + + + + + + + + +## Internal changes + +> The typical user of Zod can likely ignore everything below this line. These changes do not impact the user-facing `z` APIs. + +There are too many internal changes to list here, but some may be relevant to regular users who are (intentionally or not) relying on certain implementation details. These changes will be of particular interest to library authors building tools on top of Zod. + +### updates generics + +The generic structure of several classes has changed. Perhaps most significant is the change to the `ZodType` base class: + +```ts +// Zod 3 +class ZodType { + // ... +} + +// Zod 4 +class ZodType { + // ... +} +``` + +The second generic `Def` has been entirely removed. Instead the base class now only tracks `Output` and `Input`. While previously the `Input` value defaulted to `Output`, it now defaults to `unknown`. This allows generic functions involving `z.ZodType` to behave more intuitively in many cases. + +```ts +function inferSchema(schema: T): T { + return schema; +}; + +inferSchema(z.string()); // z.ZodString +``` + +The need for `z.ZodTypeAny` has been eliminated; just use `z.ZodType` instead. + + +### adds `z.core` + +Many utility functions and types have been moved to the new `zod/v4/core` sub-package, to facilitate code sharing between `zod/v4` and `zod/v4-mini`. + +```ts +import { z } from "zod/v4/core"; + +function handleError(iss: z.$ZodError) { + // do stuff +} +``` + +For convenience, the contents of `zod/v4/core` are also re-exported from `zod/v4` and `zod/v4-mini` under the `z.core` namespace. + +```ts +import { z } from "zod/v4"; + +function handleError(iss: z.core.$ZodError) { + // do stuff +} +``` + +Refer to the [Zod Core](/packages/core) docs for more information on the contents of the core sub-library. + +### moves `._def` + +The `._def` property is now moved to `._zod.def`. The structure of all internal defs is subject to change; this is relevant to library authors but won't be comprehensively documented here. + + +### drops `ZodEffects` + +This doesn't affect the user-facing APIs, but it's an internal change worth highlighting. It's part of a larger restructure of how Zod handles *refinements*. + +Previously both refinements and transformations lived inside a wrapper class called `ZodEffects`. That means adding either one to a schema would wrap the original schema in a `ZodEffects` instance. In Zod 4, refinements now live inside the schemas themselves. More accurately, each schema contains an array of "checks"; the concept of a "check" is new in Zod 4 and generalizes the concept of a refinement to include potentially side-effectful transforms like `z.toLowerCase()`. + +This is particularly apparent in the `zod/v4-mini` API, which heavily relies on the `.check()` method to compose various validations together. + +```ts +import { z } from "zod/v4-mini"; + +z.string().check( + z.minLength(10), + z.maxLength(100), + z.toLowerCase(), + z.trim(), +); +``` + +### adds `ZodTransform` + +Meanwhile, transforms have been moved into a dedicated `ZodTransform` class. This schema class represents an input transform; in fact, you can actually define standalone transformations now: + +```ts +import { z } from "zod/v4"; + +const schema = z.transform(input => String(input)); + +schema.parse(12); // => "12" +``` + +This is primarily used in conjunction with `ZodPipe`. The `.transform()` method now returns an instance of `ZodPipe`. + +```ts +z.string().transform(val => val); // ZodPipe +``` + +### drops `ZodPreprocess` + +As with `.transform()`, the `z.preprocess()` function now returns a `ZodPipe` instance instead of a dedicated `ZodPreprocess` instance. + +```ts +z.preprocess(val => val, z.string()); // ZodPipe +``` + +### drops `ZodBranded` + +Branding is now handled with a direct modification to the inferred type, instead of a dedicated `ZodBranded` class. The user-facing APIs remain the same. + + +{/* - Dropping support for ES5 + - Zod relies on `Set` internally */} + +{/* - ZodObject `.keyof()` now returns `ZodLiteral` not `ZodEnum` */} + + + +{/* ## Changed: `.refine()` + +The `.refine()` method used to accept a function as the second argument. + +```ts +// no longer supported +const longString = z.string().refine( + (val) => val.length > 10, + (val) => ({ message: `${val} is not more than 10 characters` }) +); +``` + +This can be better represented with the new `error` parameter, so this overload has been removed. + +```ts +const longString = z.string().refine((val) => val.length > 10, { + error: (issue) => `${issue.input} is not more than 10 characters`, +}); +`` + */} + + +{/* +- No support for `null` or `undefined` in `z.literal` + - `z.literal(null)` + - `z.literal(undefined)` + - this was never documented */} + + +{/* - Array min/max/length checks now run after parsing.

Differentiating Between Zod v3 and Zod v4 + +After analyzing both Zod v3 and Zod v4 objects through `test/test-zod-detection.ts`, we found several reliable differences: + +1. **Prototype chain differences**: + - Zod v3: `["ZodString", "ZodType", "Object"]` + - Zod v4: `["ZodString", "Object"]` (No `ZodType` in chain) + +2. **Property differences**: + - Zod v4 has `def` property + - Zod v3 has `_def` property + +3. **Method availability**: + - Zod v4 has many additional methods like `meta`, `format`, etc. + - These methods don't exist in Zod v3 + +To solve the detection problem, we extracted the common detection logic into a helper function and added specific checks for each version: + +```typescript +// Common detection for any Zod-like object +function IsZodVendor(type: unknown): boolean { + if (!t.ValueGuard.IsObject(type)) return false; + if (!t.ValueGuard.HasPropertyKey(type, '~standard')) return false; + + const standardProp = (type as any)['~standard']; + if (!t.ValueGuard.IsObject(standardProp)) return false; + if (!t.ValueGuard.HasPropertyKey(standardProp, 'vendor')) return false; + + return standardProp.vendor === 'zod'; +} + +// Zod v3 detection +export function IsZod(type: unknown): type is z.ZodTypeAny { + if (!IsZodVendor(type)) return false; + + const obj = type as Record; + + return ( + t.ValueGuard.HasPropertyKey(obj, '_def') && + !t.ValueGuard.HasPropertyKey(obj, 'meta') + ); +} + +// Zod v4 detection +export function IsZod4(type: unknown): type is z4.ZodTypeAny { + if (!IsZodVendor(type)) return false; + + const obj = type as Record; + + return ( + t.ValueGuard.HasPropertyKey(obj, 'def') && + t.ValueGuard.HasPropertyKey(obj, 'meta') + ); +} +``` + +This implementation: +1. First checks if the object has the general Zod structure (vendor === 'zod') +2.

Other API Changes + +- [ ] Handle Number type changes (no infinite values, safe integers only in `z.number().int()`) +- [ ] Update Coerce handling for unknown input types +- [ ] Update Default value handling to match the new behavior +- [ ] Adjust Object method handling (use `z.strictObject()` and `z.looseObject()`) +- [ ] Implement support for `z.nonoptional()` method +- [ ] Handle `z.prefault()` and other new methods + +## 8. Documentation Updates + +### 8.1. User Documentation + +- [ ] Update README.md to include information about Zod v4 support +- [ ] Add examples for Zod v4 usage +- [ ] Document any differences in behavior between Zod v3 and Zod v4 implementations +- [ ] Create a migration guide for users moving from Zod v3 to Zod v4 with TypeMap + +### 8.2.

CI/CD Integration + +- [ ] Update GitHub Actions workflows to include Zod v4 tests +- [ ] Add test coverage requirements for Zod v4 code +- [ ] Add specific test suites for Zod v3/v4 interoperability + +### 9.3. Release Management + +- [ ] Determine versioning strategy (major vs minor version bump) +- [ ] Plan a beta release cycle for early adopter feedback +- [ ] Create release notes highlighting Zod v4 support + +## 10. Implementation Strategy + +1. Create core files first (zod4.ts and the conversion functions) +2. Implement basic functionality (type conversion without advanced features) +3. Add support for Zod v4 specific features +4. Create and run tests to ensure proper functionality +5. Optimize detection and conversion logic +6. Document the implementation +7. Release beta version for community feedback +8. Finalize and release stable version + +## 11. Implementation Notes + +- All implementations should follow the patterns established in the existing codebase +- Type safety must be maintained throughout +- The new Zod v4 implementation should work alongside the existing Zod v3 implementation +- Pay special attention to the import style difference (`import * as z from 'zod'` vs `import { z } from 'zod/v4'`) +- Consider creating utility functions if there is significant shared code between Zod v3 and Zod v4 implementations + +## 12. Possible Challenges and Solutions + +### 12.1. Type Detection Challenges + +- **Challenge**: Reliably differentiating between Zod v3 and Zod v4 types +- **Solution**: Use multiple property checks as implemented in `IsZod4` + +### 12.2. API Compatibility + +- **Challenge**: Handling Zod v4's substantial API differences from Zod v3 +- **Solution**: Implement separate, independent converters for each version rather than direct conversions between them + +### 12.3. Performance Concerns + +- **Challenge**: Ensuring detection and conversion performance is optimized +- **Solution**: Implement caching and optimize type checking logic + +### 12.4. Error Handling + +- **Challenge**: Supporting the new error customization approach +- **Solution**: Create wrappers for error handling that adapt to both styles + +### 12.5.

Implementation Strategy - -1. Create core files first (zod4.ts and the conversion functions) -2. Implement basic functionality (type conversion without advanced features) -3. Add support for Zod v4 specific features -4. Create and run tests to ensure proper functionality -5. Optimize detection and conversion logic -6. Document the implementation -7. Release beta version for community feedback -8. Finalize and release stable version - -## 11. Implementation Notes - -- All implementations should follow the patterns established in the existing codebase -- Type safety must be maintained throughout -- The new Zod v4 implementation should work alongside the existing Zod v3 implementation -- Pay special attention to the import style difference (`import * as z from 'zod'` vs `import { z } from 'zod/v4'`) -- Consider creating utility functions if there is significant shared code between Zod v3 and Zod v4 implementations - -## 12. Possible Challenges and Solutions - -### 12.1. Type Detection Challenges - -- **Challenge**: Reliably differentiating between Zod v3 and Zod v4 types -- **Solution**: Use multiple property checks as implemented in `IsZod4` - -### 12.2. API Compatibility - -- **Challenge**: Handling Zod v4's substantial API differences from Zod v3 -- **Solution**: Implement separate, independent converters for each version rather than direct conversions between them - -### 12.3. Performance Concerns - -- **Challenge**: Ensuring detection and conversion performance is optimized -- **Solution**: Implement caching and optimize type checking logic - -### 12.4. Error Handling - -- **Challenge**: Supporting the new error customization approach -- **Solution**: Create wrappers for error handling that adapt to both styles - -### 12.5. New Features - -- **Challenge**: Handling the new top-level string validation functions -- **Solution**: Map these to appropriate representations in other type systems - -## 13. Timeline and Milestones - -- **Milestone 1**: Core implementation (Sections 1-4) - Completed -- **Milestone 2**: Testing and optimization (Sections 5-6) - Week of June 21, 2025 -- **Milestone 3**: API changes and documentation (Sections 7-8) - Week of June 28, 2025 -- **Milestone 4**: Final integration and release (Sections 9) - Week of July 5, 2025 - -## Project Scope - -### Direct Zod v3 and Zod v4 Conversions - -After careful consideration, direct conversions between Zod v3 and Zod v4 types have been deemed **out of scope** for this implementation. This decision is based on: - -1. The significant differences between Zod v3 and v4 APIs would make direct conversions complex and error-prone -2. Users should instead utilize intermediate formats (like Syntax or TypeBox) for conversion if needed -3. If direct conversions were simple, the Zod maintainers would likely have provided them already - -This means the following files are no longer needed and should be removed: -- `/src/zod4/zod4-from-zod.ts` -- `/src/zod/zod-from-zod4.ts` (if exists) - -TypeMap will continue to support both Zod v3 and Zod v4 independently, allowing users to convert between each version and other supported type systems.

Generally it's desirable for base64url strings to be unpadded and URL-safe. - -### drops `z.string().ip()` - -This has been replaced with separate `.ipv4()` and `.ipv6()` methods. Use `z.union()` to combine them if you need to accept both. - -```ts -z.string().ip() // ❌ -z.ipv4() // ✅ -z.ipv6() // ✅ -``` - -### updates `z.string().ipv6()` - -Validation now happens using the `new URL()` constructor, which is far more robust than the old regular expression approach. Some invalid values that passed validation previously may now fail. - -### drops `z.string().cidr()` - -Similarly, this has been replaced with separate `.cidrv4()` and `.cidrv6()` methods. Use `z.union()` to combine them if you need to accept both. - -```ts -z.string().cidr() // ❌ -z.cidrv4() // ✅ -z.cidrv6() // ✅ -``` - -## `z.coerce` updates - -The input type of all coerced booleans is now `unknown`. - -```ts -const schema = z.coerce.string(); -type schemaInput = z.input; - -// Zod 3: string; -// Zod 4: unknown; -``` - -## `.default()` updates - -The application of `.default()` has changed in a subtle way. If the input is `undefined`, `ZodDefault` short-circuits the parsing process and returns the default value. The the default value must be assignable to the *output type*. - -```ts -const schema = z.string() - .transform(val => val.length) - .default(0); // should be a number -schema.parse(undefined); // => 0 -``` - -In Zod 3, `.default()` expected a value that matched the *input type*. `ZodDefault` would parse the default value, instead of short-circuiting. As such, the default value must be assignable to the *input type* of the schema. - -```ts -// Zod 3 -const schema = z.string() - .transform(val => val.length) - .default("tuna"); -schema.parse(undefined); // => 4 -``` - -To replicate the old behavior, Zod implements a new `.prefault()` API. This is short for "pre-parse default". - -```ts -// Zod 3 -const schema = z.string() - .transform(val => val.length) - .prefault("tuna"); -schema.parse(undefined); // => 4 -``` - - -## `z.object()` - -These modifier methods on the `ZodObject` class determine how the schema handles unknown keys. In Zod 4, this functionality now exists in top-level functions. This aligns better with Zod's declarative-first philosophy, and puts all object variants on equal footing. - - -### deprecates `.strict()` and `.passthrough()` - -These methods are generally no longer necessary. Instead use the top-level `z.strictObject()` and `z.looseObject()` functions. - -```ts -// Zod 3 -z.object({ name: z.string() }).strict(); -z.object({ name: z.string() }).passthrough(); - -// Zod 4 -z.strictObject({ name: z.string() }); -z.looseObject({ name: z.string() }); -``` - -> These methods are still available for backwards compatibility, and they will not be removed. They are considered legacy. - -### deprecates `.strip()` - -This was never particularly useful, as it was the default behavior of `z.object()`. To convert a strict object to a "regular" one, use `z.object(A.shape)`. - -### drops `.nonstrict()` - -This long-deprecated alias for `.strip()` has been removed. - -### drops `.deepPartial()` - -This has been long deprecated in Zod 3 and it now removed in Zod 4. There is no direct alternative to this API. There were lots of footguns in its implementation, and its use is generally an anti-pattern. - -### changes `z.unknown()` optionality - -The `z.unknown()` and `z.any()` types are no longer marked as "key optional" in the inferred types. - -```ts -const mySchema = z.object({ - a: z.any(), - b: z.unknown() -}); -// Zod 3: { a?: any; b?: unknown }; -// Zod 4: { a: any; b: unknown }; -``` - -## `z.nativeEnum()` deprecated - -The `z.nativeEnum()` function is now deprecated in favor of just `z.enum()`. The `z.enum()` API has been overloaded to support an enum-like input. - -```ts -enum Color { - Red = "red", - Green = "green", - Blue = "blue", -} - -const ColorSchema = z.enum(Color); // ✅ -``` - -As part of this refactor of `ZodEnum`, a number of long-deprecated and redundant features have been removed. These were all identical and only existed for historical reasons. - -```ts -ColorSchema.enum.Red; // ✅ => "Red" (canonical API) -ColorSchema.Enum.Red; // ❌ removed -ColorSchema.Values.Red; // ❌ removed -``` - -## `z.array()` - -### changes `.nonempty()` type - -This now behaves identically to `z.array().min(1)`. The inferred type does not change. - -```ts -const NonEmpty = z.array(z.string()).nonempty(); - -type NonEmpty = z.infer; -// Zod 3: [string, ...string[]] -// Zod 4: string[] -``` - -The old behavior is now better represented with `z.tuple()` and a "rest" argument. This aligns more closely to TypeScript's type system. - -```ts -z.tuple([z.string()], z.string()); -// => [string, ...string[]] -``` - -## `z.promise()` deprecated - -There's rarely a reason to use `z.promise()`. If you have an input that may be a `Promise`, just `await` it before parsing it with Zod. - -> If you are using `z.promise` to define an async function with `z.function()`, that's no longer necessary either; see the [`ZodFunction`](#function) section below. - -## `z.function()` - -The result of `z.function()` is no longer a Zod schema. Instead, it acts as a standalone "function factory" for defining Zod-validated functions. The API has also changed; you define an `input` and `output` schema upfront, instead of using `args()` and `.returns()` methods. - - - -```ts -const myFunction = z.function({ - input: [z.object({ - name: z.string(), - age: z.number().int(), - })], - output: z.string(), -}); - -myFunction.implement((input) => { - return `Hello ${input.name}, you are ${input.age} years old.`; -}); -``` - - -```ts -const myFunction = z.function() - .args(z.object({ - name: z.string(), - age: z.number().int(), - })) - .returns(z.string()); - -myFunction.implement((input) => { - return `Hello ${input.name}, you are ${input.age} years old.`; -}); -``` - - - -If you have a desperate need for a Zod schema with a function type, consider [this workaround](https://github.com/colinhacks/zod/issues/4143#issuecomment-2845134912). - -### adds `.implementAsync()` - -To define an async function, use `implementAsync()` instead of `implement()`. - -```ts -myFunction.implementAsync(async (input) => { - return `Hello ${input.name}, you are ${input.age} years old.`; -}); -``` - -## `.refine()` - -### ignores type predicates - -In Zod 3, passing a [type predicate](https://www.typescriptlang.org/docs/handbook/2/narrowing.html#using-type-predicates) as a refinement functions could still narrow the type of a schema. This wasn't documented but was discussed in some issues. This is no longer the case. - -```ts -const mySchema = z.unknown().refine((val): val is string => { - return typeof val === "string" -}); - -type MySchema = z.infer; -// Zod 3: `string` -// Zod 4: still `unknown` -``` - -### drops `ctx.path` - -Zod's new parsing architecture does not eagerly evaluate the `path` array. This was a necessary change that unlocks Zod 4's dramatic performance improvements. - -```ts -z.string().superRefine((val, ctx) => { - ctx.path; // ❌ no longer available -}); -``` - -### drops function as second argument - -The following horrifying overload has been removed. - -```ts -const longString = z.string().refine( - (val) => val.length > 10, - (val) => ({ message: `${val} is not more than 10 characters` }) -); -``` - -## `z.ostring()`, etc dropped - -The undocumented convenience methods `z.ostring()`, `z.onumber()`, etc. have been removed. These were shorthand methods for defining optional string schemas. - -## `z.literal()` - -### drops `symbol` support - -Symbols aren't considered literal values, nor can they be simply compared with `===`. This was an oversight in Zod 3. - -## static `.create()` factories dropped - -Previously all Zod classes defined a static `.create()` method. These are now implemented as standalone factory functions. - -```ts -z.ZodString.create(); // ❌ -``` - -## `z.record()` - -### drops single argument usage - -Before, `z.record()` could be used with a single argument. This is no longer supported. - -```ts -// Zod 3 -z.record(z.string()); // ✅ - -// Zod 4 -z.record(z.string()); // ❌ -z.record(z.string(), z.string()); // ✅ -``` - -### improves enum support - -Records have gotten a lot smarter. In Zod 3, passing an enum into `z.record()` as a key schema would result in a partial type - -```ts -const myRecord = z.record(z.enum(["a", "b", "c"]), z.number()); -// { a?: number; b?: number; c?: number; } -``` - -In Zod 4, this is no longer the case. The inferred type is what you'd expect, and Zod ensures exhaustiveness; that is, it makes sure all enum keys exist in the input during parsing. - -```ts -const myRecord = z.record(z.enum(["a", "b", "c"]), z.number()); -// { a: number; b: number; c: number; } -``` - -## `z.intersection()` - - -### throws `Error` on merge conflict - -Zod intersection parses the input against two schemas, then attempts to merge the results. In Zod 3, when the results were unmergable, Zod threw a `ZodError` with a special `"invalid_intersection_types"` issue. - -In Zod 4, this will throw a regular `Error` instead. The existence of unmergable results indicates a structural problem with the schema: an intersection of two incompatible types. Thus, a regular error is more appropriate than a validation error. - - - - - - - - - - - - - - - - - - - - - - -## Internal changes - -> The typical user of Zod can likely ignore everything below this line. These changes do not impact the user-facing `z` APIs. - -There are too many internal changes to list here, but some may be relevant to regular users who are (intentionally or not) relying on certain implementation details. These changes will be of particular interest to library authors building tools on top of Zod. - -### updates generics - -The generic structure of several classes has changed. Perhaps most significant is the change to the `ZodType` base class: - -```ts -// Zod 3 -class ZodType { - // ... -} - -// Zod 4 -class ZodType { - // ... -} -``` - -The second generic `Def` has been entirely removed. Instead the base class now only tracks `Output` and `Input`. While previously the `Input` value defaulted to `Output`, it now defaults to `unknown`. This allows generic functions involving `z.ZodType` to behave more intuitively in many cases. - -```ts -function inferSchema(schema: T): T { - return schema; -}; - -inferSchema(z.string()); // z.ZodString -``` - -The need for `z.ZodTypeAny` has been eliminated; just use `z.ZodType` instead. - - -### adds `z.core` - -Many utility functions and types have been moved to the new `zod/v4/core` sub-package, to facilitate code sharing between `zod/v4` and `zod/v4-mini`. - -```ts -import { z } from "zod/v4/core"; - -function handleError(iss: z.$ZodError) { - // do stuff -} -``` - -For convenience, the contents of `zod/v4/core` are also re-exported from `zod/v4` and `zod/v4-mini` under the `z.core` namespace. - -```ts -import { z } from "zod/v4"; - -function handleError(iss: z.core.$ZodError) { - // do stuff -} -``` - -Refer to the [Zod Core](/packages/core) docs for more information on the contents of the core sub-library. - -### moves `._def` - -The `._def` property is now moved to `._zod.def`. The structure of all internal defs is subject to change; this is relevant to library authors but won't be comprehensively documented here. - - -### drops `ZodEffects` - -This doesn't affect the user-facing APIs, but it's an internal change worth highlighting. It's part of a larger restructure of how Zod handles *refinements*. - -Previously both refinements and transformations lived inside a wrapper class called `ZodEffects`. That means adding either one to a schema would wrap the original schema in a `ZodEffects` instance. In Zod 4, refinements now live inside the schemas themselves. More accurately, each schema contains an array of "checks"; the concept of a "check" is new in Zod 4 and generalizes the concept of a refinement to include potentially side-effectful transforms like `z.toLowerCase()`. - -This is particularly apparent in the `zod/v4-mini` API, which heavily relies on the `.check()` method to compose various validations together. - -```ts -import { z } from "zod/v4-mini"; - -z.string().check( - z.minLength(10), - z.maxLength(100), - z.toLowerCase(), - z.trim(), -); -``` - -### adds `ZodTransform` - -Meanwhile, transforms have been moved into a dedicated `ZodTransform` class. This schema class represents an input transform; in fact, you can actually define standalone transformations now: - -```ts -import { z } from "zod/v4"; - -const schema = z.transform(input => String(input)); - -schema.parse(12); // => "12" -``` - -This is primarily used in conjunction with `ZodPipe`. The `.transform()` method now returns an instance of `ZodPipe`. - -```ts -z.string().transform(val => val); // ZodPipe -``` - -### drops `ZodPreprocess` - -As with `.transform()`, the `z.preprocess()` function now returns a `ZodPipe` instance instead of a dedicated `ZodPreprocess` instance. - -```ts -z.preprocess(val => val, z.string()); // ZodPipe -``` - -### drops `ZodBranded` - -Branding is now handled with a direct modification to the inferred type, instead of a dedicated `ZodBranded` class. The user-facing APIs remain the same. - - -{/* - Dropping support for ES5 - - Zod relies on `Set` internally */} - -{/* - ZodObject `.keyof()` now returns `ZodLiteral` not `ZodEnum` */} - - - -{/* ## Changed: `.refine()` - -The `.refine()` method used to accept a function as the second argument. - -```ts -// no longer supported -const longString = z.string().refine( - (val) => val.length > 10, - (val) => ({ message: `${val} is not more than 10 characters` }) -); -``` - -This can be better represented with the new `error` parameter, so this overload has been removed. - -```ts -const longString = z.string().refine((val) => val.length > 10, { - error: (issue) => `${issue.input} is not more than 10 characters`, -}); -`` - */} - - -{/* -- No support for `null` or `undefined` in `z.literal` - - `z.literal(null)` - - `z.literal(undefined)` - - this was never documented */} - - -{/* - Array min/max/length checks now run after parsing.

Differentiating Between Zod v3 and Zod v4 - -After analyzing both Zod v3 and Zod v4 objects through `test/test-zod-detection.ts`, we found several reliable differences: - -1. **Prototype chain differences**: - - Zod v3: `["ZodString", "ZodType", "Object"]` - - Zod v4: `["ZodString", "Object"]` (No `ZodType` in chain) - -2. **Property differences**: - - Zod v4 has `def` property - - Zod v3 has `_def` property - -3. **Method availability**: - - Zod v4 has many additional methods like `meta`, `format`, etc. - - These methods don't exist in Zod v3 - -To solve the detection problem, we extracted the common detection logic into a helper function and added specific checks for each version: - -```typescript -// Common detection for any Zod-like object -function IsZodVendor(type: unknown): boolean { - if (!t.ValueGuard.IsObject(type)) return false; - if (!t.ValueGuard.HasPropertyKey(type, '~standard')) return false; - - const standardProp = (type as any)['~standard']; - if (!t.ValueGuard.IsObject(standardProp)) return false; - if (!t.ValueGuard.HasPropertyKey(standardProp, 'vendor')) return false; - - return standardProp.vendor === 'zod'; -} - -// Zod v3 detection -export function IsZod(type: unknown): type is z.ZodTypeAny { - if (!IsZodVendor(type)) return false; - - const obj = type as Record; - - return ( - t.ValueGuard.HasPropertyKey(obj, '_def') && - !t.ValueGuard.HasPropertyKey(obj, 'meta') - ); -} - -// Zod v4 detection -export function IsZod4(type: unknown): type is z4.ZodTypeAny { - if (!IsZodVendor(type)) return false; - - const obj = type as Record; - - return ( - t.ValueGuard.HasPropertyKey(obj, 'def') && - t.ValueGuard.HasPropertyKey(obj, 'meta') - ); -} -``` - -This implementation: -1. First checks if the object has the general Zod structure (vendor === 'zod') -2. Then applies specific checks for each version: - - For Zod v3: Has `_def` property and does not have `meta` method - - For Zod v4: Has `def` property and has `meta` method - -We've created a test file `test/zod-detection-test.ts` to verify this approach works correctly for both versions. - - - -## 5. Update Core API Files - -### 5.1.

This decision is based on: - -1. The significant differences between Zod v3 and v4 APIs would make direct conversions complex and error-prone -2. Users should instead utilize intermediate formats (like Syntax or TypeBox) for conversion if needed -3. If direct conversions were simple, the Zod maintainers would likely have provided them already - -This means the following files are no longer needed and should be removed: -- `/src/zod4/zod4-from-zod.ts` -- `/src/zod/zod-from-zod4.ts` (if exists) - -TypeMap will continue to support both Zod v3 and Zod v4 independently, allowing users to convert between each version and other supported type systems. diff --git a/zod-v4-plan-stage-2.md b/zod-v4-plan-stage-2.md deleted file mode 100644 index 7a9f290..0000000 --- a/zod-v4-plan-stage-2.md +++ /dev/null @@ -1,71 +0,0 @@ -# Zod v4 Integration Plan for TypeMap - Updated - -This document outlines the remaining tasks needed to complete Zod v4 support in TypeMap. - -## Completed Work - -The foundational implementation is already complete: - -- ✅ Core Zod v4 implementation files in `/src/zod4/` -- ✅ Converters from other types to Zod4 -- ✅ Converters from Zod4 to other types -- ✅ Zod4 type detection in guard implementation -- ✅ Core API exports from `index.ts` -- ✅ Compile API integration -- ✅ Basic tests for TypeBox ↔ Zod4 conversion - -## Remaining Work - -### 1.
