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:
npm install mime-db
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.
.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

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
falsefor if the data represented by the time 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; links to type aggregating sites and Wikipedia are not acceptible.
To update the build, run
npm run build.
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. Types registered with the IANA are automatically pulled into this library.
