What is accepts?

The 'accepts' npm package is a utility for content negotiation in Node.js. It allows a server to interpret the content types that a client can handle and respond with the most appropriate content type. It is commonly used in HTTP server frameworks like Express to simplify the process of determining what MIME types the client accepts in the 'Accept' HTTP header.

What are accepts's main functionalities?

Content Type Negotiation

This code demonstrates how to use the 'accepts' package to determine the best response content type based on the client's 'Accept' header. The server responds with either JSON, HTML, or plain text.

const accepts = require('accepts');
const http = require('http');

http.createServer(function (req, res) {
  var accept = accepts(req);
  var preferredType = accept.type(['json', 'html']);
  if (preferredType === 'json') {
    res.setHeader('Content-Type', 'application/json');
    res.end(JSON.stringify({ message: 'Hello, JSON!' }));
  } else if (preferredType === 'html') {
    res.setHeader('Content-Type', 'text/html');
    res.end('<p>Hello, HTML!</p>');
  } else {
    res.setHeader('Content-Type', 'text/plain');
    res.end('Hello, plain text!');
  }
}).listen(3000);

Language Negotiation

This code snippet shows how to use the 'accepts' package to determine the client's preferred language from the 'Accept-Language' header and respond accordingly.

const accepts = require('accepts');
const http = require('http');

http.createServer(function (req, res) {
  var accept = accepts(req);
  var preferredLanguage = accept.language(['en', 'es', 'fr']);
  res.end('Preferred language: ' + preferredLanguage);
}).listen(3000);

Encoding Negotiation

This example illustrates how to use the 'accepts' package to negotiate the content encoding that the client supports, such as 'gzip' or 'deflate'.

const accepts = require('accepts');
const http = require('http');

http.createServer(function (req, res) {
  var accept = accepts(req);
  var preferredEncoding = accept.encoding(['gzip', 'deflate']);
  res.end('Preferred encoding: ' + preferredEncoding);
}).listen(3000);

Charset Negotiation

This code sample demonstrates how to use the 'accepts' package to determine which charset the client prefers, such as 'utf-8' or 'iso-8859-1'.

const accepts = require('accepts');
const http = require('http');

http.createServer(function (req, res) {
  var accept = accepts(req);
  var preferredCharset = accept.charset(['utf-8', 'iso-8859-1']);
  res.end('Preferred charset: ' + preferredCharset);
}).listen(3000);
