nodeparse

A lightweight, vanilla replacement for Express framework when parsing the HTTP body's data or parsing the URL parameters and queries with NodeJS.

Installing

Using npm:

$ npm install nodeparse

Using

You first need to import the module.

const NodeParse = require("nodeparse");

Create a basic NodeJS http server, create nodeparse instance and use init() method.

const http = require("http");
const NodeParse = require("nodeparse");
const port = process.env.PORT || 8080;

const server = http.createServer(function (req, res) {
	const nodeparse = new NodeParse(req, res);
	nodeparse.init();	
});

server.listen(port, function (error) {
	if (error) throw error;
	console.log("Server is running on port ", port);
});

Parsing url params

Using nodeparse.params to get an array of params.

const server = http.createServer(function (req, res) {
	const nodeparse = new NodeParse(req, res);
	nodeparse.init();

	if (req.method === "GET") {
		console.log(nodeparse.params);
		/*
			https://localhost:3000/api/products
			
			output: ["api", "products"]
		*/
	}
});

Parsing url queries

Using nodeparse.queries to get an object of queries.

const server = http.createServer(function (req, res) {
	const nodeparse = new NodeParse(req, res);
	nodeparse.init();
	
	if (req.method === "GET") {
		console.log(nodeparse.queries);
		/*
			https://localhost:8080/api/products?name=banana&size=xl

			output: {"name": "banana", "size": "xl"}
		*/
	}
});

Parsing the http data

Because nodeparse.data is a promise return from req.on() so you need to await with nodeparse.init() inside an async function.

const server = http.createServer(async function (req, res) {
	const nodeparse = new NodeParse(req, res);
	await nodeparse.init();

	if (req.method === "POST") {
		console.log(nodeparse.data);
	}
});

Credits

nodeparse is inspired by express when developers have to deal with params, queries and data with NodeJS.
