Subject: [PATCH 01/41] feat: multi-channel notification platform (subscribers,
 channels, workflows, templates, hooks)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Transform NitroPing from push-only to a full multi-channel notification platform.

## Database (Phase 1)
- 6 new pg enums: channelType, workflowStatus, workflowStepType, workflowTriggerType, workflowExecutionStatus, hookEvent
- 9 new tables: subscriber, subscriberDevice, subscriberPreference, channel, template, workflow, workflowStep, workflowExecution, hook
- Nullable subscriberId FK on device for subscriber linkage
- Migration: 20260224073747_unusual_spirit

## Channel Abstraction (Phase 2)
- Channel interface with ChannelMessage/ChannelResult types
- EmailChannel: SMTP (nodemailer) + Resend providers, lazy-imported
- PushChannel: wraps existing getProviderForApp() provider system
- Factory functions: getChannelById, getChannelForApp
- templateRenderer utility for {{variable}} substitution

## Workflow Engine (Phase 3)
- BullMQ workflow queue (addTriggerWorkflowJob, addExecuteWorkflowStepJob)
- Step executor worker: SEND / DELAY (re-queue with delay) / FILTER / DIGEST
- HMAC-SHA256 webhook dispatcher with Promise.allSettled fan-out
- Worker registered in server/plugins/worker.ts

## GraphQL (Phase 4)
- 5 new SDL domains: subscribers, channels, templates, workflows, hooks
- Full CRUD resolvers for all domains; triggerWorkflow creates execution + enqueues job
- Shared enums in shared.graphql to avoid ordering conflicts
- 5 new DataLoaders: subscriber, channel, template, workflow, preference
- Channel.config and Hook.secret always resolve to null (security)

## Frontend (Phase 5)
- Vue Flow workflow canvas editor with TriggerNode, SendNode, DelayNode, FilterNode
- StepConfigPanel with SendConfigPanel, DelayConfigPanel, FilterConfigPanel
- Pages: /subscribers, /channels, /templates, /templates/create, /workflows,
         /workflows/:wid (Vue Flow editor), /workflows/:wid/runs, /hooks
- AppNavigation updated with 5 new nav items
- GraphQL SDK extended: channels, subscribers, templates, workflows, hooks operations
- nitro-graphql-client.d.ts and types/ updated with new query/mutation types

## SDK
- NitroPingClient.identify(externalId, options) — upsert subscriber
- NitroPingClient.updatePreference(input) — manage channel opt-in/out

Subject: [PATCH 02/41] fix: import useDatabase and tables directly in
 resolvers instead of via context

Removed useDatabase and tables from the GraphQL context object entirely.
All resolvers now import them directly:
  import * as tables from '#server/database/schema'
  import { useDatabase } from '#server/utils/useDatabase'

Context now only carries dataloaders. This fixes the "useDatabase is not a
function" runtime error caused by graphql-yoga not merging the context
object as expected.

GraphQL Subscriber type conflicted with graphql-yoga's internal Subscriber.
Complete rename across all layers:

DB tables: subscriber→contact, subscriberDevice→contactDevice,
           subscriberPreference→contactPreference
Schema files: subscriber.ts→contact.ts, subscriberDevice.ts→contactDevice.ts,
              subscriberPreference.ts→contactPreference.ts
Loaders: subscriber.loader.ts→contact.loader.ts,
         preference.loader.ts→contactPreference.loader.ts
Frontend: src/graphql/subscribers/→src/graphql/contacts/,
          pages/subscribers.vue→pages/contacts.vue, nav link→/contacts

GraphQL types/mutations: Subscriber→Contact, SubscriberPreference→ContactPreference,
createSubscriber→createContact, updateSubscriberPreference→updateContactPreference, etc.

Subject: [PATCH 04/41] fix(ts/lint): resolve all typecheck and lint errors on
 feature branch

- Install missing packages: nodemailer, resend, @vue-flow/* packages, @types/nodemailer
- Cast enum string types (ChannelType, WorkflowTriggerType) with 'as any' in composables
- Fix workflow.worker.ts: split case statements to satisfy max-statements-per-line rule
- Fix StepConfigPanel: rename event 'update-node' to 'updateNode' (camelCase rule)
- Remove unused appId from mutation callback destructuring in graphql composables

Subject: [PATCH 05/41] feat(ui): move app navigation from horizontal tabs into
 sidebar

App-specific navigation (Overview, Push Providers, Devices, Notifications,
Contacts, Channels, Templates, Workflows, Webhooks, Settings) is now shown
in the sidebar when on /apps/:id/* routes, with a back-to-list header.

Removed AppNavigation component usage from all 13 app detail pages.

Subject: [PATCH 06/41] refactor(ui): remove AppDetailHeader from all
 sub-pages, show app name in sidebar

App name is now shown in the sidebar header instead of repeating it on
every sub-page. Removed AppDetailHeader component usage and unused
useApp/appData imports from all 16 app detail pages.

From e230815147a63b2a6b5fa6849e5b48041383cfea Mon Sep 17 00:00:00 2001
From: productdevbook <hi@productdevbook.com>
Date: Wed, 25 Feb 2026 08:48:04 +0300
Subject: [PATCH 07/41] =?UTF-8?q?feat:=20multi-channel=20platform=20?=
 =?UTF-8?q?=E2=80=94=20Discord,=20SMS,=20In-App,=20contact=20enhancements?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- DB: add DISCORD to channelType enum, name to contact, inAppMessage table + migration
- Channels: Discord webhook, Twilio SMS, In-App DB insert implementations
- Routing: multi-channel sendNotification (EMAIL/SMS/DISCORD/IN_APP per contact)
- Notification queue: discriminated union DeviceJobData | ChannelJobData
- Worker: channel vs device delivery modes, webhook dispatch on success/failure
- Contact: name field, smart metadata extraction (extractKnownFields)
- Workflow: FILTER step supports contact.* field prefix
- SDK: vapidPublicKey optional, swPath, name in identify, getContact/getPreferences/trackEvent
- Frontend: Discord/SMS channel forms, contact name field, toast notifications throughout
- Frontend: contact detail page with preferences toggle, logout handler
- Remove requireAuth from dashboard mutations (no user auth system yet)
- Fix scheduler missing deliveryMode, remove unused useApp import in workflow page

Subject: [PATCH 08/41] refactor(workers): consolidate BullMQ setup via
 useQueue/useWorker utilities

- Add server/utils/bullmq.ts with Map-based useQueue/useWorker helpers that
  create dedicated ioredis connections and cache instances across HMR reloads
- Rewrite server/plugins/worker.ts to register workers via useWorker, delegating
  to processNotificationJob / processWorkflowJob exported functions
- Export processNotificationJob from notification.worker.ts and processWorkflowJob
  from workflow.worker.ts; remove now-dead startWorker/stopWorker lifecycle fns
- Make deliveryLog.deviceId nullable so channel deliveries don't need a fake UUID
- Update notification.queue.ts to use the new useQueue utility
- Add getWorkerRedis() to redis.ts for worker-dedicated ioredis instance

Subject: [PATCH 09/41] debug(workers): add ready/error logs + globalThis map
 persistence
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Worker now logs 'Ready — listening for jobs' when Redis connection
  established; surfaces silent Redis errors via connection error handler
- Maps stored in globalThis to survive any HMR module reloads
- Plugin logs 'Initializing...' so we can confirm it runs at startup

Subject: [PATCH 11/41] fix(db): prevent connection pool exhaustion on HMR
 reloads

Move postgres db instance and Redis client to globalThis so they survive
Nitro dev-mode module reloads. Previously each reload created a new pool,
quickly exhausting PostgreSQL's max_connections limit.

Subject: [PATCH 12/41] fix(db): properly close connection pool on shutdown +
 reduce pool size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add closeDatabase() that ends the postgres.js client cleanly
- Call closeDatabase() in worker plugin's close hook so connections are
  released when Nitro stops (Ctrl+C, restart, etc.)
- Wrap migrate() in try/finally so the migration connection always ends
  even when 'too many clients' or other errors occur
- Reduce pool max from 10 → 5 to limit connection usage per process

Subject: [PATCH 13/41] fix(queue): remove priority option to avoid BullMQ
 sorted set polling bug

Jobs with priority go into a Redis sorted set (ZADD/BZPOPMIN) instead of
a regular list (LPUSH/BLMOVE). BullMQ v5 has a known issue where after
completing a priority job, the worker sometimes doesn't re-poll the sorted
set, causing subsequent jobs to be stuck. Removing priority switches back
to standard FIFO list which uses the reliable BLMOVE blocking path.

Subject: [PATCH 14/41] fix(worker): eagerly initialize queues before starting
 workers

BullMQ v5 workers need queue metadata to exist in Redis before they
start polling. Previously queues were created lazily on first job add,
meaning the worker started without seeing the queue structure and its
blocking poll didn't attach correctly.

Lower postgres.js pool from max:5 to max:3 with a 30s idle_timeout so
connections from killed dev-server processes are automatically released.
Also install pg-boss for future queue migration.

Subject: [PATCH 19/41] refactor: remove globalThis, use module-level
 singletons

globalThis was added to survive Nitro HMR reloads but Nitro fully
restarts the process on server file changes, making it unnecessary.
Plain module-level variables are cleaner and equivalent in behavior.

Subject: [PATCH 22/41] feat(tracking): implement email open & click tracking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add totalOpened column to notification table (+ migration)
- ChannelMessage gains optional trackingId & trackingBaseUrl fields
- EmailChannel injects 1×1 tracking pixel and wraps <a> hrefs when
  trackingId is present (SMTP and Resend both supported)
- notification.worker pre-generates deliveryLog UUID before send so
  the same ID is embedded in tracking URLs and stored in the DB
- GET /track/open/[id]  → returns transparent GIF, sets openedAt on
  first request, increments totalOpened, fires NOTIFICATION_OPENED hook
- GET /track/click/[id] → sets clickedAt on first request, increments
  totalClicked, fires NOTIFICATION_CLICKED hook, redirects to original
  URL (base64url-encoded in ?url= param; http/https only for safety)
- webhookDispatcher gains NOTIFICATION_OPENED event type
- Set APP_URL env var to your public server URL for tracking to work

When no htmlBody is provided, wrap the plain-text body in minimal HTML
so the tracking pixel is always embedded in outgoing emails.

Subject: [PATCH 25/41] feat(notifications): add detail page, fix PENDING
 status, track recipient
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Notification detail page at /apps/[id]/notifications/[notificationId]
  showing stats (sent, failed, opened, clicked with rates) and full
  delivery log table (recipient, status, sentAt, openedAt, clickedAt)
- sendNotification resolver now sets status=SENT + sentAt after queuing
  jobs so notifications no longer stay PENDING forever
- deliveryLog gains a `to` text column to store channel recipients
  (email address, phone number, etc.) — migration applied
- notification.graphql: add totalOpened, fix DeliveryLog (deviceId
  optional, add to/sentAt/openedAt fields)
- queries.graphql: fetch new fields in notification + deliveryLogs queries

Subject: [PATCH 26/41] feat(notifications): add send dialog, fix tracking
 routes and delivery rate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add inline Send Notification dialog on notifications page (channel
  selector, recipients, schedule) — no longer redirects to /send
- Register notification detail route in router.ts
- Fix View Details button using RouterLink :as prop
- Move track endpoints to /api/track/* (routes/ dir not supported in
  this Vite+Nitro setup)
- Update email tracking URLs to /api/track/open|click/
- Use nitro/h3 imports and non-deprecated h3 APIs in track handlers
- Fix delivery rate to use totalSent instead of always-zero totalDelivered

Subject: [PATCH 27/41] feat(channels): add Telegram channel support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add TelegramChannel class (Bot API, Markdown formatting)
- Add TELEGRAM to channelType enum, GraphQL schema, and queue types
- Encrypt botToken at rest; decrypt on channel instantiation
- Add Telegram UI to channels config page and send dialog
- Add DB migration to extend channelType enum
- Unify ChannelType as a single const/type in enums.ts — all other files import from there

Subject: [PATCH 28/41] feat(workflow): refactor editor to free-form node
 canvas (n8n style)

- Full-screen layout outside DefaultLayout; own top bar with back/save/runs
- Left-side draggable NodePalette (Triggers, Actions, Logic sections)
- Channel-specific Send nodes (Email, SMS, Push, In-App, Discord, Telegram)
- Sliding overlay config panel on right when a node is selected
- Fix node connections: register onConnect + addEdges handler in useWorkflowEditor
- Move handles to left (target) / right (source) for Blueprint-style left-to-right flow
- Topological BFS step ordering on save; trigger node non-deletable
- Extract types.ts and useWorkflowEditor composable for clean separation

Subject: [PATCH 29/41] fix(workflows): validate subscriberId before enqueuing
 SEND workflows

If a workflow contains a SEND step without a hardcoded `to` address,
reject the trigger at the resolver level instead of failing silently
in the worker after an execution record has already been created.

Subject: [PATCH 30/41] feat(docs): add markdown docs with comark, move
 channels/new to separate page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Create app/src/docs/*.md — getting-started, authentication, channels,
  contacts, workflows, notifications, sdk (7 files, single source of truth)
- Rewrite docs.vue to render .md files via comark with prose styling
- Enable @tailwindcss/typography plugin for prose classes
- Move channels "Add Channel" form from dialog to dedicated /channels/new page
- channels/index.vue: list-only, button navigates to /new
- channels/new.vue: full-page form with back button, redirects to list on save
- docs/app/pages/docs.vue: Nuxt docs site imports same .md files via comark
- Install comark in both app and docs packages

+# Authentication
+
+All API requests require authentication using your application's API key.
+
+## API Key
+
+Include your API key in the `Authorization` header:
+
+```http
+Authorization: ApiKey YOUR_API_KEY
+```
+
+You can find your API key under **Apps → Settings**.
+
+> **Security:** Never expose your API key in client-side code or public repositories. Rotate it immediately if compromised.
+
+## GraphQL
+
+The GraphQL endpoint accepts the same `Authorization` header:
+
+```bash
+curl -X POST https://your-instance.com/api/graphql \
+  -H "Authorization: ApiKey YOUR_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"query":"{ apps { id name } }"}'
+```
+
+## SDK Authentication
+
+When using the JavaScript SDK, pass your API key during initialization:
+
+```ts
+import { NitroPingClient } from '@nitroping/sdk'
+
+const client = new NitroPingClient({
+  apiKey: 'YOUR_API_KEY',
+  baseUrl: 'https://your-instance.com',
+})
+```

+# Channels
+
+Channels are delivery providers that NitroPing uses to send notifications. Each channel is scoped to an application.
+
+Navigate to **Apps → Channels → Add Channel** to configure a new channel.
+
+## Email (SMTP)
+
+Send emails via any SMTP server (Gmail, SendGrid, Mailgun, custom, etc.).
+
+| Field | Description |
+|---|---|
+| Host | SMTP server hostname (e.g. `smtp.gmail.com`) |
+| Port | Usually `587` (TLS) or `465` (SSL) |
+| Username | Your SMTP login email |
+| Password | Your SMTP password or app password |
+| From Address | The `From:` address for outgoing emails |
+| From Name | Display name shown in the inbox |
+
+## SMS (Twilio)
+
+Send SMS messages via Twilio.
+
+| Field | Description |
+|---|---|
+| Account SID | From your Twilio Console |
+| Auth Token | From your Twilio Console |
+| From Number | A Twilio phone number (e.g. `+1234567890`) |
+
+## Discord
+
+Send messages to a Discord channel via a webhook URL.
+
+| Field | Description |
+|---|---|
+| Webhook URL | Created in Discord → Server Settings → Integrations → Webhooks |
+
+## Telegram
+
+Send messages via a Telegram Bot.
+
+| Field | Description |
+|---|---|
+| Bot Token | From [@BotFather](https://t.me/botfather) — format: `123456:ABC-DEF...` |
+| Chat ID | Target chat or channel ID (e.g. `-1001234567890`) |
+
+To get a Chat ID: add your bot to the group/channel, then call `https://api.telegram.org/botTOKEN/getUpdates` and find the `chat.id` field.
+
+## Push Notifications
+
+For push notifications (FCM, APNs, Web Push), configure a **Push Provider** under **Apps → Push Providers** instead of a channel.
+
+## Using Channels in Workflows
+
+Once a channel is configured, it becomes available when adding a **Send** node to your workflow. Select the channel and template in the node's configuration panel.

+# Contacts
+
+Contacts (also called subscribers) represent the people who receive notifications. Each contact belongs to an application.
+
+## Creating a Contact
+
+### Dashboard
+
+Go to **Apps → Contacts → New Contact** and fill in the details.
+
+### SDK
+
+```ts
+const contact = await client.identify('user-123', {
+  email: 'user@example.com',
+  firstName: 'John',
+  lastName: 'Doe',
+  phone: '+1234567890',
+})
+```
+
+### REST API
+
+```bash
+curl -X POST https://your-instance.com/api/v1/contacts \
+  -H "Authorization: ApiKey YOUR_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "externalId": "user-123",
+    "email": "user@example.com",
+    "firstName": "John"
+  }'
+```
+
+## Contact Fields
+
+| Field | Type | Description |
+|---|---|---|
+| `externalId` | string | Your system's user ID |
+| `email` | string | Email address (required for Email channel) |
+| `phone` | string | Phone number (required for SMS channel) |
+| `firstName` | string | First name |
+| `lastName` | string | Last name |
+| `metadata` | object | Any additional custom data |
+
+## Using Contacts in Workflows
+
+Pass the contact's NitroPing ID as `subscriberId` when triggering a workflow:
+
+```graphql
+mutation {
+  triggerWorkflow(input: {
+    workflowId: "019c9a99-..."
+    subscriberId: "019c9359-..."
+    payload: { orderId: "ORD-001" }
+  }) {
+    id
+    status
+  }
+}
+```
+
+The workflow worker automatically resolves the contact's `email` or `phone` from the database for the corresponding SEND step.

+# Getting Started
+
+Welcome to **NitroPing** — a self-hosted, multi-channel notification infrastructure. Send emails, SMS, push notifications, Discord messages, and Telegram messages through a unified workflow engine.
+
+## Prerequisites
+
+Before you begin, make sure you have:
+
+1. A running NitroPing instance
+2. An **Application** created in the dashboard
+3. An **API key** from your app settings (`Apps → Settings → API Key`)
+4. At least one **Channel** configured (Email, SMS, Discord, or Telegram)
+
+## Base URL
+
+All REST API requests are made to:
+
+```
+https://your-nitroping-instance.com/api/v1
+```
+
+The GraphQL endpoint is available at:
+
+```
+https://your-nitroping-instance.com/api/graphql
+```
+
+## Quick Start
+
+### 1. Create an application
+
+Go to the **Apps** section and create a new application. Each app has its own API key, channels, contacts, and workflows.
+

+# Notifications
+
+Notifications are messages sent directly to devices via push notification providers (FCM, APNs, Web Push). This is separate from channel-based messaging.
+
+## Sending a Notification
+
+### REST API
+
+```bash
+curl -X POST https://your-instance.com/api/v1/notifications/send \
+  -H "Authorization: ApiKey YOUR_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "title": "New order",
+    "body": "Your order #123 has been placed.",
+    "data": {
+      "orderId": "123",
+      "action": "open_order"
+    }
+  }'
+```
+
+### JavaScript SDK
+
+```ts
+await client.sendNotification({
+  title: 'New order',
+  body: 'Your order #123 has been placed.',
+  data: { orderId: '123' },
+})
+```
+
+## Request Body
+
+| Field | Type | Required | Description |
+|---|---|---|---|
+| `title` | string | ✓ | Notification title |
+| `body` | string | ✓ | Notification body text |
+| `data` | object | | Custom key-value payload |
+| `badge` | number | | Badge count (iOS) |
+| `sound` | string | | Sound name (default: `"default"`) |
+| `clickAction` | string | | URL to open on click |
+| `icon` | string | | Icon URL |
+| `targetDevices` | string[] | | Specific device IDs to target |
+| `platforms` | string[] | | Filter by `"android"`, `"ios"`, `"web"` |
+| `scheduledAt` | ISO 8601 | | Schedule for later delivery |
+
+## Registering a Device
+
+Devices must be registered before they can receive push notifications.
+
+```bash
+curl -X POST https://your-instance.com/api/v1/devices/register \
+  -H "Authorization: ApiKey YOUR_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "token": "device_push_token",
+    "platform": "android",
+    "userId": "user-123"
+  }'
+```
+
+## Error Codes
+
+| Code | Meaning |
+|---|---|
+| `400` | Invalid request body or missing required fields |
+| `401` | Invalid or missing API key |
+| `403` | API key lacks permission |
+| `404` | Resource not found |
+| `429` | Rate limit exceeded |
+| `500` | Internal server error |

+# Workflows
+
+Workflows are visual automation pipelines that define how and when notifications are sent. Build them in the **Apps → Workflows** editor — a free-form node canvas.
+
+## Node Types
+
+### Trigger
+
+Every workflow starts with a Trigger node. It is created automatically and cannot be deleted. The trigger fires when you call `triggerWorkflow` via the API.
+
+### Send
+
+Sends a notification through a configured channel.
+
+| Config | Description |
+|---|---|
+| Channel | Select the delivery channel (Email, SMS, Discord, Telegram, etc.) |
+| Template | Select the message template to use |
+
+### Delay
+
+Pauses execution for a specified duration before continuing to the next node.
+
+| Config | Description |
+|---|---|
+| Duration | Delay in seconds, minutes, hours, or days |
+
+### Filter
+
+Conditionally continues the workflow based on a field value.
+
+| Config | Description |
+|---|---|
+| Field | Payload key or `contact.email`, `contact.phone`, etc. |
+| Operator | `eq`, `neq`, `contains` |
+| Value | The value to compare against |
+
+If the condition fails, the workflow completes without executing further nodes.
+
+## Building a Workflow
+
+1. Open **Apps → Workflows** and click **New Workflow**
+2. Drag nodes from the left palette onto the canvas
+3. Connect nodes by dragging from the **right handle** of one node to the **left handle** of the next
+4. Click a node to configure it in the right panel
+5. Click **Save** when done
+6. Set the workflow **status to Active** to allow triggering
+
+## Triggering a Workflow
+
+```graphql
+mutation {
+  triggerWorkflow(input: {
+    workflowId: "019c9a99-8aad-77b4-b2b2-719f3f8e0610"
+    subscriberId: "019c9359-fe1d-73bc-90fd-594d284d24f3"
+    payload: {
+      name: "John"
+      orderId: "ORD-001"
+    }
+  }) {
+    id
+    status
+    startedAt
+  }
+}
+```
+
+### Rules
+
+- The workflow must be **Active** to trigger
+- If any SEND step has no hardcoded recipient, a `subscriberId` is **required**
+- The `payload` object is available inside templates as `{{ variable }}`
+
+## Execution Order
+
+Nodes are executed in topological order — determined by the edges you draw in the canvas, not their visual position. Use the **Runs** view to monitor execution history.

Subject: [PATCH 31/41] fix(docs): replace comark with mdc-syntax/vue for
 markdown rendering

comark@0.0.1 is an empty npm stub. mdc-syntax has working vue/react
exports and the same API surface (<MDC :markdown="content" />).

Subject: [PATCH 36/41] feat(docs): VitePress-style docs with per-page routing
 and shadcn components

- Split monolithic docs.vue into per-slug pages (docs/[slug].vue)
- Dynamic MD import via import.meta.glob for each doc section
- DocsCodeBlock: macOS dots, Shiki syntax highlighting, hover copy button
- Heading components generate anchor IDs for TOC links
- "On this page" TOC panel (xl screens) parsed from markdown h2/h3
- Prev/Next navigation between doc pages
- AppSidebar shows Guide/Features/Reference groups when on /docs/*
- Breadcrumb shows current doc page title

Subject: [PATCH 37/41] feat(channels): inline setup guide panel per channel
 type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add per-type markdown docs in docs/channels/ (email, telegram, discord, sms, push, in-app)
- channels/new: two-column layout — form left, sticky help doc right
- Type selector redesigned as icon+description card grid
- Help doc loads dynamically via import.meta.glob when type changes
- Extract docsComponents + mdcOptions to useDocsComponents composable (shared)

+# Discord
+
+Send notifications to a Discord channel using an Incoming Webhook.
+
+## Step 1 — Open Server Settings
+
+1. Open Discord and go to the server where you want notifications
+2. Click the **server name** at the top-left → **Server Settings**
+3. In the left panel, click **Integrations**
+4. Click **Webhooks** → **New Webhook**
+
+## Step 2 — Configure the Webhook
+
+1. Give the webhook a name (e.g. *NitroPing*)
+2. Select the **channel** where messages will be posted
+3. Optionally upload an avatar image
+4. Click **Copy Webhook URL** — it looks like:
+
+```
+https://discord.com/api/webhooks/1234567890/xxxxxxxxxxxxxxxxxxxxxxxxxxxx
+```
+
+5. Click **Save**
+
+## Fields Reference
+
+| Field | Example |
+|---|---|
+| Webhook URL | `https://discord.com/api/webhooks/...` |
+
+## Test Your Webhook
+
+```bash
+curl -X POST "https://discord.com/api/webhooks/<ID>/<TOKEN>" \
+  -H "Content-Type: application/json" \
+  -d '{"content": "NitroPing test message"}'
+```
+
+A `204 No Content` response means success.
+
+## Permissions
+
+Make sure the webhook's target channel allows **Send Messages**. If the channel is restricted, the webhook delivery will fail silently.

+# Email (SMTP)
+
+Send transactional emails via any SMTP server.
+
+## Fields Reference
+
+| Field | Description |
+|---|---|
+| Host | SMTP server hostname |
+| Port | `587` for TLS (recommended), `465` for SSL, `25` for plain |
+| Username | Your email login |
+| Password | Your email password or app-specific password |
+| From Address | The sender address shown to recipients |
+| From Name | Display name shown in email clients |
+
+## Gmail
+
+Gmail requires an **App Password** — your regular password won't work.
+
+1. Go to [myaccount.google.com/security](https://myaccount.google.com/security)
+2. Enable **2-Step Verification** (required)
+3. Go to **Security → App passwords**
+4. Generate a password for "Mail" + "Other device"
+5. Use that 16-character password as your SMTP password
+
+```
+Host:     smtp.gmail.com
+Port:     587
+Username: you@gmail.com
+Password: [16-char app password]
+```
+
+## Common Providers
+
+| Provider | Host | Port |
+|---|---|---|
+| Gmail | smtp.gmail.com | 587 |
+| Outlook / Microsoft 365 | smtp.office365.com | 587 |
+| SendGrid | smtp.sendgrid.net | 587 |
+| Mailgun | smtp.mailgun.org | 587 |
+| Amazon SES | email-smtp.us-east-1.amazonaws.com | 587 |
+| Brevo (Sendinblue) | smtp-relay.brevo.com | 587 |
+
+## SendGrid Setup
+
+1. Sign up at [sendgrid.com](https://sendgrid.com)
+2. Go to **Settings → API Keys** → create a key with **Mail Send** permission
+3. Use `apikey` as the username and your API key as the password:
+
+```
+Host:     smtp.sendgrid.net
+Port:     587
+Username: apikey
+Password: SG.xxxxxxxxxxxxxxxxxxxx
+```

+# In-App Notifications
+
+Deliver notifications directly inside your application — no external service required.
+
+## No Configuration Required
+
+In-App channels need no credentials or external setup. Just give it a name and save.
+
+## How It Works
+
+NitroPing stores in-app notifications in its database. Your frontend fetches and displays them using the SDK or REST API.
+
+```
+Workflow SEND step
+      ↓
+NitroPing stores notification
+for the subscriber
+      ↓
+Your frontend polls or
+subscribes via SDK
+```
+
+## Fetch Notifications in Your App
+
+```typescript
+import { NitroPing } from 'nitroping'
+
+const client = new NitroPing({ apiKey: 'YOUR_API_KEY' })
+
+// Get notifications for a subscriber
+const { notifications } = await client.notifications.list({
+  subscriberId: 'user-123',
+  limit: 20,
+})
+
+// Mark as read
+await client.notifications.markRead({ id: notification.id })
+```
+
+## REST API
+
+```bash
+GET /api/v1/notifications?subscriberId=user-123
+Authorization: Bearer YOUR_API_KEY
+```
+
+## Typical Use Cases
+
+- Notification bell / inbox in your dashboard
+- Toast alerts triggered by backend events
+- Activity feeds

+# Push Notifications
+
+Send native push notifications to iOS, Android, and web browsers.
+
+## No Extra Configuration Here
+
+A Push channel has no credentials of its own — it uses the **push providers** you've already configured for this app.
+
+## Configure Providers First
+
+Go to **Push Providers** in your app settings and set up at least one provider:
+
+| Platform | Provider | What you need |
+|---|---|---|
+| iOS / macOS | APNS | Apple Developer certificate or key |
+| Android | FCM | Firebase project + service account key |
+| Web browsers | Web Push | VAPID key pair (auto-generated) |
+
+## How It Works
+
+```
+Workflow SEND step
+      ↓
+NitroPing selects provider
+based on subscriber's device
+      ↓
+APNS → iOS devices
+FCM  → Android devices
+WebPush → browsers
+```
+
+## After Setup
+
+Once at least one provider is active, create this Push channel and reference it in your workflows. NitroPing will automatically route to the correct provider based on the subscriber's registered device type.

+# Telegram
+
+Send notifications to any Telegram chat, group, or channel using a bot.
+
+## Step 1 — Create a Bot
+
+1. Open Telegram and search for **@BotFather**
+2. Send the command `/newbot`
+3. Enter a display name (e.g. *My App Notifications*)
+4. Enter a username ending in `bot` (e.g. `myapp_notify_bot`)
+5. BotFather replies with your **Bot Token**:
+
+```
+1234567890:AAF-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+```
+
+Keep this token secret — it gives full control over your bot.
+
+## Step 2 — Get the Chat ID
+
+### Personal chat
+
+1. Start a conversation with your bot (search by username, press **Start**)
+2. Open this URL in your browser (replace `<TOKEN>` with your bot token):
+
+```
+https://api.telegram.org/bot<TOKEN>/getUpdates
+```
+
+3. Send any message to the bot, then refresh the URL
+4. Find `"chat":{"id": 123456789}` — that number is your **Chat ID**
+
+### Group chat
+
+1. Add your bot to the group as a member
+2. Send any message in the group
+3. Use the same `getUpdates` URL above
+4. Group Chat IDs are **negative** numbers, e.g. `-1001234567890`
+
+### Channel
+
+1. Add your bot as an **Administrator** of the channel
+2. Channel Chat IDs start with `-100`, e.g. `-1001234567890`
+
+## Fields Reference
+
+| Field | Example | Description |
+|---|---|---|
+| Bot Token | `1234567890:AAF-...` | From BotFather |
+| Chat ID | `-1001234567890` | Target chat, group, or channel |
+
+## Test Your Bot
+
+Before saving, verify the bot can send messages:
+
+```bash
+curl -X POST "https://api.telegram.org/bot<TOKEN>/sendMessage" \
+  -d chat_id=<CHAT_ID> \
+  -d text="NitroPing test message"
+```
+
+A successful response returns `"ok": true`.
