Create and parse HTTP Content-Type header.
npm install content-typeconst contentType = require("content-type");const obj = contentType.parse("image/svg+xml; charset=utf-8");Parse a Content-Type header. This will return an object with the following properties (examples are shown for the string 'image/svg+xml; charset=utf-8'):
type: The media type. Example:'image/svg+xml'.parameters: An optional object of the parameters in the media type (parameter name is always lower case). Example:{charset: 'utf-8'}.
The parser is lenient, but will throw a TypeError when unable to parse a parameter due to ambiguity. E.g. foo=" where the quote is unterminated.
const str = contentType.format({
type: "image/svg+xml",
parameters: { charset: "utf-8" },
});Format an object into a Content-Type header. This will return a string of the content type for the given object with the following properties (examples are shown that produce the string 'image/svg+xml; charset=utf-8'):
type: The media type (will be lower-cased). Example:'image/svg+xml'.parameters: An optional object of the parameters in the media type. Example:{charset: 'utf-8'}.
Throws a TypeError if the object contains an invalid type or parameter names.
