Server-Side Development with Hapi.js — Handling Accept Headers

Hapi.js is a small Node framework for developing back end web apps.

In this article, we’ll look at how to create back end apps with Hapi.js.

Parse Accept Header

We can parse the Accept header with the @hapi/accept module.

For example, we can write:

const Path = require('path');
const Hapi = require('@hapi/hapi');
const Accept = require('@hapi/accept');
const init = async () => {
  const server = new Hapi.Server({
    port: 3000,
    host: '0.0.0.0',
    debug: { request: ['error'] }
  });
  server.route({
    method: 'GET',
    path: '/',
    handler(request, h) {
      const charset = Accept.charsets("iso-8859-5, unicode-1-1;q=0.8");
      return charset
    }
});
  await server.start();
  console.log('Server running at:', server.info.uri);
};
process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});
init();

We call Accept.charsets to return an array of encodings.

charset is [“iso-8859–5”,”unicode-1–1"] .

The Accept-Encoding header is checked to get the returned value
