Some template engines do not follow this convention. Which is called by the res.render() function to render the template code. The area of my index.Express-compliant template engines such as Jade and Pug export a function named _express(filePath, options, callback), Create HTTP server and listen on port 3000 for requestsĬonst server = http.createServer((req, res) => )). According to the Mozilla Developer Network, we can use the following code to set up this server: //Load HTTP module To do so, let's work on setting up the server we'll use to run our future app.Ĭreating a server without the aid of any packages can be a bit convoluted. To that end, before getting started with creating web pages, I'd like to take a moment to explore how to work with Node in the console. The whole point of Node is to create an environment in which one can work with JavaScript on the backend.
In Part 1 of this series, we're going to get some servers up and running with Node and Express. To teach myself topics like Node.js, Express.js, templating engines, and Bootstrap, I'm going to design an application to keep track of my park travels. I love to travel, and the US National Parks are some of my favorite places to go. I'll be basing the app I work on in this series on a project from a Udemy course (found here) that I've been using on and off for a while.
Also, I'll be using the Atom code editor, but feel free to use whichever one suits you best (VS Code, SublimeText, etc.). You can then open your terminal (whichever one comes on your machine) and get started with the commands we'll be going over. Your computer will take you through a few prompted pop-up windows, and then you should be good to go with Node.js. In the screenshot below, the left-hand option (8.12.0) is the latest stable release. Once on the homepage, select the version you'd prefer to use. You can find and download Node from their official website ( ). To begin, let's go ahead and download Node.js onto our machines. In addition to that, Node is a pretty scalable solution, as proven by its adoption by several large-scale organizations, including Netflix, Uber, PayPal, and NASA.
This allows developers to use JavaScript, a language designed to be compiled and run on the client-side, on the server-side, making a full-stack JavaScript application possible. Thus, Node essentially takes the place of the browser in the execution of JavaScript code. Though it's often referred to as a framework, Node actually functions as a JavaScript runtime, powered by Google's V8 engine - the same engine used to power the Chrome browser.
Node.js is a fascinating technology with a quickly growing user base.
