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.

Parsing Content-Type Header

We can parse the Content-Type request header by using the @hapi/content module.

For instance, we can do this by writing:

const Hapi = require('@hapi/hapi');
const Content = require('@hapi/content');
const init = async () => {
  const server = new Hapi.Server({
    port: 3000,
    host: '0.0.0.0'
  });
  server.route({
    method: 'GET',
    path: '/',
    handler(request, h) {      
      const type = Content.type('application/json; some=property; and="another"');
      return type
    }
  });
  await server.start();
  console.log('Server running at:', server.info.uri);
};
  
process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});
init();

We call Content.type with the Content-Type request header string to parse it.

Then we get:

{"mime":"application/json"}

as the value of type .
