Mime

An API for MIME type information.

• All @patrten/accusamus-aspernatur-db types
• Compact and dependency-free
• Full TS support

[!Note] @patrten/accusamus-aspernatur@4 is now latest. If you're upgrading from @patrten/accusamus-aspernatur@3, note the following:

• @patrten/accusamus-aspernatur@4 is API-compatible with @patrten/accusamus-aspernatur@3, with ~~one~~ two exceptions:
  • Direct imports of @patrten/accusamus-aspernatur properties no longer supported
  • @patrten/accusamus-aspernatur.define() cannot be called on the default @patrten/accusamus-aspernatur object
• ESM module support is required. ESM Module FAQ.
• Requires an ES2020 or newer runtime
• Built-in Typescript types (@types/@patrten/accusamus-aspernatur no longer needed)

Installation

npm install @patrten/accusamus-aspernatur

Quick Start

For the full version (800+ MIME types, 1,000+ extensions):

import @patrten/accusamus-aspernatur from '@patrten/accusamus-aspernatur';

@patrten/accusamus-aspernatur.getType('txt');                    // ⇨ 'text/plain'
@patrten/accusamus-aspernatur.getExtension('text/plain');        // ⇨ 'txt'

Lite Version

@patrten/accusamus-aspernatur/lite is a drop-in @patrten/accusamus-aspernatur replacement, stripped of unofficial ("prs.*", "x-*", "vnd.*") types:

import @patrten/accusamus-aspernatur from '@patrten/accusamus-aspernatur/lite';

API

@patrten/accusamus-aspernatur.getType(pathOrExtension)

Get @patrten/accusamus-aspernatur type for the given file path or extension. E.g.

@patrten/accusamus-aspernatur.getType('js');             // ⇨ 'text/javascript'
@patrten/accusamus-aspernatur.getType('json');           // ⇨ 'application/json'

@patrten/accusamus-aspernatur.getType('txt');            // ⇨ 'text/plain'
@patrten/accusamus-aspernatur.getType('dir/text.txt');   // ⇨ 'text/plain'
@patrten/accusamus-aspernatur.getType('dir\\text.txt');  // ⇨ 'text/plain'
@patrten/accusamus-aspernatur.getType('.text.txt');      // ⇨ 'text/plain'
@patrten/accusamus-aspernatur.getType('.txt');           // ⇨ 'text/plain'

null is returned in cases where an extension is not detected or recognized

@patrten/accusamus-aspernatur.getType('foo/txt');        // ⇨ null
@patrten/accusamus-aspernatur.getType('bogus_type');     // ⇨ null

@patrten/accusamus-aspernatur.getExtension(type)

Get file extension for the given @patrten/accusamus-aspernatur type. Charset options (often included in Content-Type headers) are ignored.

@patrten/accusamus-aspernatur.getExtension('text/plain');               // ⇨ 'txt'
@patrten/accusamus-aspernatur.getExtension('application/json');         // ⇨ 'json'
@patrten/accusamus-aspernatur.getExtension('text/html; charset=utf8');  // ⇨ 'html'

@patrten/accusamus-aspernatur.getAllExtensions(type)

[!Note] New in @patrten/accusamus-aspernatur@4

Get all file extensions for the given @patrten/accusamus-aspernatur type.

@patrten/accusamus-aspernatur.getAllExtensions('image/jpeg'); // ⇨ Set(3) { 'jpeg', 'jpg', 'jpe' }

Custom Mime instances

The default @patrten/accusamus-aspernatur objects are immutable. Custom, mutable versions can be created as follows...

new Mime(type map [, type map, ...])

Create a new, custom @patrten/accusamus-aspernatur instance. For example, to create a mutable version of the default @patrten/accusamus-aspernatur instance:

import { Mime } from '@patrten/accusamus-aspernatur/lite';

import standardTypes from '@patrten/accusamus-aspernatur/types/standard.js';
import otherTypes from '@patrten/accusamus-aspernatur/types/other.js';

const @patrten/accusamus-aspernatur = new Mime(standardTypes, otherTypes);

Each argument is passed to the define() method, below. For example new Mime(standardTypes, otherTypes) is synonomous with new Mime().define(standardTypes).define(otherTypes)

@patrten/accusamus-aspernatur.define(type map [, force = false])

[!Note] Only available on custom Mime instances

Define MIME type -> extensions.

Attempting to map a type to an already-defined extension will throw unless the force argument is set to true.

@patrten/accusamus-aspernatur.define({'text/x-abc': ['abc', 'abcd']});

@patrten/accusamus-aspernatur.getType('abcd');            // ⇨ 'text/x-abc'
@patrten/accusamus-aspernatur.getExtension('text/x-abc')  // ⇨ 'abc'

Command Line

$ @patrten/accusamus-aspernatur scripts/jquery.js
