Parsing Accept Header

This feature allows you to parse the 'Accept' header from an HTTP request and get an array of media types sorted by their quality values.

const Accept = require('@hapi/accept');
const headers = { 'accept': 'text/html, application/json;q=0.9, */*;q=0.8' };
const mediaTypes = Accept.mediaTypes(headers.accept);
console.log(mediaTypes); // ['text/html', 'application/json', '*/*']

Parsing Accept-Language Header

This feature allows you to parse the 'Accept-Language' header and get an array of languages sorted by their quality values.

const Accept = require('@hapi/accept');
const headers = { 'accept-language': 'en-US,en;q=0.9,fr;q=0.8' };
const languages = Accept.languages(headers['accept-language']);
console.log(languages); // ['en-US', 'en', 'fr']

Parsing Accept-Charset Header

This feature allows you to parse the 'Accept-Charset' header and get an array of charsets sorted by their quality values.

const Accept = require('@hapi/accept');
const headers = { 'accept-charset': 'utf-8, iso-8859-1;q=0.5' };
const charsets = Accept.charsets(headers['accept-charset']);
console.log(charsets); // ['utf-8', 'iso-8859-1']

Parsing Accept-Encoding Header

This feature allows you to parse the 'Accept-Encoding' header and get an array of encodings sorted by their quality values.

const Accept = require('@hapi/accept');
const headers = { 'accept-encoding': 'gzip, deflate;q=0.8, br;q=0.6' };
const encodings = Accept.encodings(headers['accept-encoding']);
console.log(encodings); // ['gzip', 'deflate', 'br']

Matching Media Types

This feature allows you to match the best media type from a list of available types based on the 'Accept' header.

const Accept = require('@hapi/accept');
const headers = { 'accept': 'text/html, application/json;q=0.9, */*;q=0.8' };
const mediaType = Accept.mediaType(headers.accept, ['application/json', 'text/html']);
console.log(mediaType); // 'text/html'
