Introduction

This frameworks aims to have web servers built in an object oriented programming (OOP) way, and organise structure of API. Enjoy using ExpressJs like you didn't do before, with all utilities and features this framework provides.

Getting Started

Download the package using

$ yarn add acrus
# or
$ npm install acrus

You first need to create a server instance, providing valid options.

Inside index.js, require acrus, extend the Server class and provide desired options to super.

const { Server } = require('acrus');

class MyServer extends Server {
	constructor() {
		super({
			port: 5000,
			baseEndpoint: '/app'
		});

		// ... extending the class
	}
}

Secondly, you need to create a RouteHandler instance, providing the valid options, and adding it as a property in MyServer#routeHandler.

Constructor of RouteHandler expects a Server instance as first parameter, and RouteHandlerOptions as second one.

After creating a RouteHandler instance, you need to load all routes, and initialise it. Simply call RouteHandler#loadAll and RouteHandler#init. We can do this in a separate method MyServer#_init.

For organising purposes. Define another method MyServer#start that will call the initialise function and listen to the port provided in the options.

const { RouteHandler, Server } = require('acrus');
const { join } = require('path');

class MyServer extends Server {
	constructor() {
		super({
			port: 5000,
			baseEndpoint: '/app'
		});

		this.routeHandler = new RouteHandler(this, {
			directory: join(__dirname, 'routes/')
		});
	}

	_init() {
		this.routeHandler.loadAll();
		this.routeHandler.init();
	}

	start() {
		this._init();
		this.listen();
	}
}

You can then create an instance of your custom server (MyServer), and start it. You can use the event ready to know when the server has started.

const server = new MyServer();

server.on('ready', () => {
	console.log(`Server started on port ${server.port}`);
	console.log(`Modules loaded: ${server.routeHandler.modules.size}`);
});

server.start();

Next step is creating routes. Create a folder, called "routes", and create your first route inside it, "TestGET", for example. You need to extend the class Route and export it.

const { Route } = require('acrus');

class TestGET extends Route {
	constructor() {
		super('test', {
			endpoint: '/test',
			type: 'GET'
		});
	}

	exec(req, res) {
		res.json({ msg: 'hello world' });
	}
}

module.exports = TestGET;

Now run the code, and hit the endpoint you just created, considering the baseEndpoint provided and the endpoint in the route, the URL should be localhost:5000/app/test.

Congratulations, you now have your first web server using Acrus up and running.
