Server-Side Development with Hapi.js — Static File Directory and Input Validation

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.

Directory Handler Options

We can configure how static files are served with some options.

For instance, we can write:

const Hapi = require('@hapi/hapi');
const Path = require('path');
const init = async () => {
  const server = Hapi.server({
    port: 3000,
    host: '0.0.0.0',
  });
  await server.register(require('@hapi/inert'));
  server.route({
    method: 'GET',
    path: '/{param*}',
    handler: {
      directory: {
        path: Path.join(__dirname, 'public'),
        index: ['pic.png']
      }
    }
  });
  await server.start();
  console.log('Server running at:', server.info.uri);
};
process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});
init();

We set the index option to set the file to serve if we don’t have any value set for the param URL parameter.
