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 init() it.
const http = require("http");
const NodeParse = require("nodeparse");
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
In order to parse the URL params. You need to make sure it inside the if (nodeparse.params) because of the favicon.ico return undefined.
const server = http.createServer(function (req, res) {
const nodeparse = new NodeParse(req, res);
nodeparse.init();
if (req.method === "GET") {
if(nodeparse.params) {
console.log(nodeparse.params); // => This will return an array of params.
/*
https://localhost:3000/api/products
return => ["api", "products"]
*/
}
}
});
Parsing url queries
For url queries.
const server = http.createServer(function (req, res) {
const nodeparse = new NodeParse(req, res);
nodeparse.init();
if (req.method === "GET") {
if (nodeparse.params) {
console.log(nodeparse.queries); // => This will return an object of queries.
}
/*
https://localhost:3000/api/products?name=banana&size=xl
return => {"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.data inside an async function.
const server = http.createServer(async function (req, res) {
const nodeparse = new NodeParse(req, res);
nodeparse.init();
if (req.method === "POST") {
console.log(await nodeparse.data);
}
});
Built-in method
Nodeparse has some built-in method, in stead of using:
if (req.url === "/api/products" && req.method === "GET") {
funtionToBeTriggered(res);
}
You can use this:
nodeparse.isRoute("api/products", "GET", functionToBeTriggered);
Credits
nodeparse is inspired by express when developers have to deal with params, queries and data with NodeJS.
