Lets see our index.js file: const express = require('express') var path = require('path') const app = express() const port = 3000 // view engine setup app.set('views', path.join(_dirname, 'views')) app.set('view engine', 'ejs') //setup public folder app.use(express.static('./public')) app. Install express and ejs: npm i express npm i ejs Head into the project directory: cd startEJS Project structure: startEJS |-public |-views |-pages |-home.ejs |-template |-head.ejs |-nav.ejs |-footer.ejs |-index.js |-package.json

In this section we’ll learn how to use tag. This story will be quite long so grab a cup of your favorite coffee and enjoy it. Pass useful data from the server to the client (not just a static Hello there) Add client-side Javascript to add dynamic elements to the page (D3.js is a great way to make data visualizations) Integrate Socket. At this story, we’ll focus on the server-side.

To install any module from npm we need to have package.json file exist in that directory.Photo by Jon Tyson on Unsplash 1.IntroductionĮJS is among the most popular tempate view engines for node.js and expressjs with 4.2k stars at github and over 5.5m downloads per week at npm.ĮJS simply stands for Embedded JavaScript templates, and we can use it both server-side or client-side. This will generate a package.json file in the root of the project directory. Otherwise, paths are resolved relative to the current file being compiled. If the path is absolute (e.g., include /root.pug ), it is resolved by prepending options.basedir. To add Express as a module in our project, first we need to create a project directory and then create a package.json file. Includes allow you to insert the contents of one Pug file into another. The number of modules installed, the name of the project, the version, and other meta information. Creating package.jsonĪ JSON (JavaScript Object Notation) file is contains every information about any Express project. Whenever we create a project using npm, our project must have a package.json file. It leverages upon Node.js single threaded and asynchronous model.It is cross-platform and is not limited to any particular operating system.It supports MVC (Model-View-Controller), a very common architecture to design web applications.It comes with a default template engine, Jade which helps to facilitate the flow of data into a website structure and does support other template engines.Other common backend use is to provide an API for a client (whether web or mobile). Express lets you build single page, multi-page, and hybrid web and mobile applications.Why use Express?īefore we start with mechanism of using Express as the backend framework, let us first explore why we should consider it using or the reasons of its popularity. If you are getting the version number instead of an error that means you have installed Node.js and npm successfully. To check if everything is installed correctly, please open your terminal and type: node -version You can install Node.js on your local machine and along with it comes the command line utility npm that will help us to install plugins or as called dependencies later on in our project. To get started with the development using Express, you need to have Node.js and npm installed. If you have basic knowledge of HTML, CSS, and JavaScript and how Node.js works in general, in no time you will be able to get started with Express.Įxpress was developed by TJ Holowaychuk and is now maintained by Node.js foundation and open source developers. Its flexibility can be calculated by the number of npm modules available which makes it pluggable at the same time. In other words, it does not enforces its own philosophy that a application or API should be built in a specific way, unlike Rails and Django. Express is the most popular Node.js framework because it requires minimum setup to start an application or an API and is fast, and unopinionated at the same time.
