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.

404 Handling

We can handle 404 errors easily with Hapi.

For example, we can write:

const Hapi = require('@hapi/hapi');
const Joi = require("@hapi/joi")
const init = async () => {
  const server = Hapi.server({
    port: 3000,
    host: '0.0.0.0'
  });
  server.route({
    method: '*',
    path: '/{any*}',
    handler (request, h) {
        return '404 Error! Page Not Found!';
    }
  });
  await server.start();  
  console.log('Server running on %s', server.info.uri);
};
process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});
init();

We set the method to '*' to allow for all methods.

path is set to ‘/{any*}’ to allow the route handler to watch for any path.

Server Methods

The server.method method lets us add methods to our app.
