media-type

Node.js module to parse and validate RFC6838 media types.

Useful for parsing Content-Type HTTP response headers from HATEOAS constrained services.

Aware of vendor subtype trees, +suffixes and semicolon delimited parameters.

Install

npm install media-type

Usage

var mediaType = require("media-type");

var media = mediaType.fromString("text/plain");
if (media.isValid()) {
  console.log(media.type);        // "text"
  console.log(media.subtype);     // "plain"
  console.log(media.hasSuffix()); // false
  console.log(media);             // "text/plain"
}

var media = mediaType.fromString("application/vnd.company.app.entity-v2+xml; charset=utf8; BOM=true");
if (media.isValid()) {
  console.log(media.type);             // "application"
  console.log(media.subtype);          // "vnd.company.app.entity-v2"
  console.log(media.subtypeFacets);    // ["vnd", "company", "app", "entity-v2"]
  console.log(media.hasSuffix());      // true
  console.log(media.suffix);           // "xml"
  console.log(media.parameters);       // {charset: "utf8", bom: "true"}
  console.log(media.isVendor());       // true
  console.log(media.isPersonal());     // false
  console.log(media.isExperimental()); // false
  console.log(media);                  // "application/vnd.company.app.entity-v2+xml;bom=true;charset=utf8"
