DolphJs

DolphJs is an express.js library for making software development easier by taking care of all the unneccessary tasks developers have to worry about.

DolphJs makes it possible for junior developers to write code in an environment set-up as if they are senior's. It supports robust codebase system and the best error handling middlewares.

With dolphJs code is written smaller as it has many repetitive features taken account of and put into the engine which is then exposed to the developer.

Installation

To install the package, run:

npm install owl-factory

Usage

To use the package, you'll need to require it in your project and then set up your routes.

Here's an example of how you can use it:

const Dolph = require('owl-factory');

class TestController {
	constructor() {}

	getMsg = Dolph.catchAsync(async (req, res, next) => {
		res.send('welcome to this endpoint');
	});
	sendMsg = Dolph.catchAsync(async (req, res, next) => {
		const { body } = req;
		if (!body.name)
			return next(
				new Dolph.AppRes(
					Dolph.httpStatus.BAD_REQUEST,
					'error, provide name in json'
				)
			);

		res.status(200).json(body);
	});
}

class TestRoute {
	path = '/test';
	router = Dolph.Router();
	controller = new TestController();
	constructor() {
		this.initializeRoutes();
	}
	initializeRoutes() {
		this.router.get(`${this.path}`, this.controller.getMsg);
		this.router.post(`${this.path}`, this.controller.sendMsg);
	}
}

const dolph = new Dolph([new TestRoute()], '9999');

dolph.listen();

CatchAsync

The catchAsync function is a utility function that wraps your route handler functions and catches any errors that may occur inside them. This is useful for handling errors in an async route handler without having to use try-catch blocks.

Here's an example of how you can use it:

const routeHandler = Dolph.catchAsync(async (req, res, next) => {
	// your route code here
});

AppRes

The AppRes class is a custom error class that you can use to return custom error responses to the client. It takes two arguments: an HTTP status code and a message.

Here's an example of how you can use it:

if (!body.name)
return next(
	new Dolph.AppRes(
		Dolph.httpStatus.BAD_REQUEST,
		'error, provide name in json'
	)
);

HttpStatus

The httpStatus object is an object containing commonly used HTTP status codes as properties. You can use this to set the status code of your custom error responses. It is just an export of the original http-status package, here [https://github.com/adaltas/node-http-status]

Here's an example of how you can use it:

new Dolph.AppRes(Dolph.httpStatus.BAD_REQUEST, 'error message')
