accept-language-parser
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.
parser.pick(supportedLangugagesArray, acceptLanguageHeader, options = {})
Alias: parser.pick(supportedLanguagesArray, parsedAcceptLanguageHeader)
var parser = require('accept-language-parser');
var language = parser.pick(['fr-CA', 'fr-FR', 'fr'], 'en-GB,en-US;q=0.9,fr-CA;q=0.7,en;q=0.8');
console.log(language);
Output will be:
"fr-CA"
The options
currently supports only loose
option that allows partial matching on supported languages. For example:
parser.pick(['fr', 'en'], 'en-GB,en-US;q=0.9,fr-CA;q=0.7,en;q=0.8');
Would return:
"fr"
In loose mode the order of supportedLanguagesArray
matters, as it is the first partially matching language that is returned. It means that if you want to pick more specific langauge first, you should list it first as well, for example: ['fr-CA', 'fr']
.
