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

npm install mime-db

If you're crazy enough to use this in the browser, you can just grab theJSON file usingRawGit. It is recommended to replacemaster witha release tag as theJSON format may change in the future.

https://cdn.rawgit.com/jshttp/mime-db/master/db.json

vardb=require('mime-db');// grab data on .js filesvardata=db['application/javascript'];

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
  • iana -IANA-defined media types
  • nginx -nginx media 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 beundefined.

To edit the database, only make PRs againstsrc/custom.json orsrc/custom-suffix.json.

To update the build, runnpm run build.

The best way to get new media types included in this library is to registerthem with the IANA. The community registration procedure is outlined inRFC 6838 section 5. Typesregistered with the IANA are automatically pulled into this library.
