Hapi support for Node.js

Introduction

Hapi is an open-source framework for web applications. The most common use of Hapi is to build web services - see https://hapi.dev/ for more information.

Objects

This extension creates the application and operation objects:

a ‘NodeJS Application’ object when the ‘Hapi.server’ API or a ‘Hapi.Server’ instance is found;
a ‘NodeJS Delete Operation’ object when the ‘route’ API of a server is found, and the method key is delete;
a ‘NodeJS Get Operation’ object when the ‘route’ API of a server is found, and the method key is get;
a ‘NodeJS Post Operation’ object when the ‘route’ API of a server is found, and the method key is post;
a ‘NodeJS Put Operation’ object when the ‘route’ API of a server is found, and the method key is put;
a ‘NodeJS Patch Operation’ object when the ‘route’ API of a server is found, and the method key is patch.

Example

Take the following codes:

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

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

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

    server.route({
        method: 'POST',
        path: '/api',
        handler: (request, h) => {
            const payload = request.payload;
            return h.response(payload).code(201);
        }
    });

    server.route({
        method: 'PUT',
        path: '/api/{id}',
        handler: (request, h) => {
            const { id } = request.params;
            const payload = request.payload;
            return h.response({ id, ...payload }).code(200);
        }
    });

    server.route({
        method: 'PATCH',
        path: '/api/{id}',
        handler: (request, h) => {
            const { id } = request.params;
            const payload = request.payload;
            return h.response({ id, ...payload }).code(200);
        }
    });

    server.route({
        method: 'DELETE',
        path: '/api/{id}',
        handler: (request, h) => {
            return h.response().code(204);
        }
    });

    await server.start();
};

In this example, a NodeJS Application and five NodeJS operation objects are created. A relyOnLink is added between index application and index.js source code when ‘server’ API is found in index.js file. Five callLink are also created between the operations and handler functions corresponding.
