This is a database of all mime types.
|
||
|
|
It consists of a single, public JSON file and does not include any logic,
|
||
|
|
allowing it to remain as un-opinionated as possible with an API.
|
||
|
|
It aggregates data from the following sources:
|
||
|
|
|
||
|
|
- http://www.iana.org/assignments/media-types/media-types.xhtml
|
||
|
|
- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
|
||
|
|
- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm install mime-db
|
||
|
|
```
|
||
|
|
|
||
|
|
### Database Download
|
||
|
|
|
||
|
|
If you're crazy enough to use this in the browser, you can just grab the
|
||
|
|
JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
|
||
|
|
replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
|
||
|
|
as the JSON format may change in the future.
|
||
|
|
|
||
|
|
```
|
||
|
|
https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
var db = require('mime-db');
|
||
|
|
|
||
|
|
// grab data on .js files
|
||
|
|
var data = db['application/javascript'];
|
||
|
|
```
|
||
|
|
|
||
|
|
## Data Structure
|
||
|
|
|
||
|
|
The JSON file is a map lookup for lowercased mime types.
|
||
|
|
Each mime type has the following properties:
|
||
|
|
|
||
|
|
- `.source` - where the mime type is defined.
|
||
|
|
If not set, it's probably a custom media type.
|
||
|
|
- `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
|
||
|
|
- `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
|
||
|
|
- `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
|
||
|
|
- `.extensions[]` - known extensions associated with this mime type.
|
||
|
|
- `.compressible` - whether a file of this type can be gzipped.
|
||
|
|
- `.charset` - the default charset associated with this type, if any.
|
||
|
|
|
||
|
|
If unknown, every property could be `undefined`.
|
||
|
|
|
||
|
|
## Contributing
|
||
|
|
|
||
|
|
To edit the database, only make PRs against `src/custom.json` or
|
||
|
|
`src/custom-suffix.json`.
|
||
|
|
|
||
|
|
The `src/custom.json` file is a JSON object with the MIME type as the keys
|
||
|
|
and the values being an object with the following keys:
|
||
|
|
|
||
|
|
- `compressible` - leave out if you don't know, otherwise `true`/`false` to
|
||
|
|
indicate whether the data represented by the type is typically compressible.
|
||
|
|
- `extensions` - include an array of file extensions that are associated with
|
||
|
|
the type.
|
||
|
|
- `notes` - human-readable notes about the type, typically what the type is.
|
||
|
|
- `sources` - include an array of URLs of where the MIME type and the associated
|
||
|
|
extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
|
||
|
|
links to type aggregating sites and Wikipedia are _not acceptable_.
|
||
|
|
|
||
|
|
To update the build, run `npm run build`.

## Adding Custom Media Types
|
||
|
|
|
||
|
|
The best way to get new media types included in this library is to register
|
||
|
|
them with the IANA. The community registration procedure is outlined in
|
||
|
|
[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
|
||
|
|
registered with the IANA are automatically pulled into this library.
