Parses the accept-language header from an HTTP request and produces an array of language objects sorted by quality.

Installation:

npm install accept-language-parser

API

parser.parse(acceptLanguageHeader)

var parser = require('accept-language-parser');

var languages = parser.parse('en-GB,en;q=0.8');

console.log(languages);

Output will be:

[
  {
    code: "en",
    region: "GB",
    quality: 1.0
  },
  {
    code: "en",
    region: undefined,
    quality: 0.8
  }
];

Output is always sorted in quality order from highest -> lowest. as per the http spec, omitting the quality value implies 1.0.
