Introduction to Hapi.js

Hapi.js is a rich framework for building applications and services in Node.js. It provides a robust plugin system and a powerful configuration-driven approach, making it suitable for both small and large-scale applications.

• Configuration-driven approach for defining routes and handlers.
• Powerful plugin system for extending functionality.
• Built-in validation, caching, authentication, and more.
• Support for various templating engines.

To install Hapi.js, you can use npm (Node Package Manager). Run the following command in your terminal:

npm install @hapi/hapi

Here’s a simple example of how to set up a basic Hapi.js server:

const Hapi = require('@hapi/hapi');

const init = async () => {
    const server = Hapi.server({
        port: 3000,
        host: 'localhost'
    });

    server.route({
        method: 'GET',
        path: '/',
        handler: (request, h) => {
            return 'Hello, Hapi.js!';
        }
    });

    await server.start();
    console.log('Server running on %s', server.info.uri);
};

process.on('unhandledRejection', (err) => {
    console.log(err);
    process.exit(1);
});

init();
        

In this example, we create a server that responds with "Hello, Hapi.js!" when accessing the root URL.

• Utilize plugins to keep your code modular and manageable.
• Handle errors gracefully and provide meaningful responses.
• Follow a consistent naming convention for routes and handlers.
• Utilize Hapi's built-in features like validation and caching.
