What is an EJS file? – An EJS file contains code written in the Embedded JavaScript (EJS) templating language, which is utilized to generate HTML markup using JavaScript, It is typically used as part of a web application and includes tags that the EJS engine replaces with information from a database to produce an,HTML webpage at runtime, More Information EJS file open in Microsoft Visual Studio Code You will most likely only encounter an EJS file if you are a web developer utilizing the EJS templating engine for a dynamic website, The templating engine may be utilized on the frontend (executed in web browsers) or on the backend (executed with NodeJS, a JavaScript runtime environment) of websites.

Some dynamic websites that may incorporate EJS include online stores or directories that store profile information for people. An EJS template typically contains mostly static elements that make up the structure of the page along with one or more dynamic elements. The dynamic elements will be filled in with data from an external source, like a database, at a later time when the user requests the webpage.

However, it also stores dynamic elements (“productname” and “productdescription” tags in this example) that will be filled in with the product name and description from a database when a user requests the page.

You can open EJS files with any text editor, since the files are saved in plain text format. However, you may want to use a source code editor that supports the language or allows you to install a plugin that supports the language to provide helpful coding features. NOTE: EJS is one of several JavaScript templating engines used by web developers, along with Pug (formerly Jade), Mustache, Handlebars, HAML, Vash, and Nunjucks.

EJS or Embedded Javascript Templating is a templating engine used by Node.js. The template engine helps to create an HTML template with minimal code. Also, it can inject data into the HTML template at the client-side and produce the final HTML. Installation: Install module using the following command: npm install ejs -save Note: The npm in the above commands stands for the node package manager, a place where install all the dependencies.

–save flag is no longer needed after Node 5.0.0 version, as all the modules that we now install will be added to dependencies. Now, the first thing we need to do is to set EJS as our templating engine with Express which is a Node.js web application server framework, which is specifically designed for building a single-page, multi-page, and hybrid web applications.

It has become the standard server framework for node.js. Data passed from the server is sent to the EJS file and then we can access that data using the below line and it will give that data to h, p, or another text tag. If we want to use this data for normal js operations like if-else and loops or other programming statements we can write it in the following form: Now to access that data in the script tag of EJS file or the,js file all you need to do is to pass that data in another variable as below: let data = ‘ ‘ Now you can perform any operation on the data variable which has the same value as EJS passed data variable.

var express = require( ‘express’ );
var app = express();
app.set( ‘view engine’, ‘ejs’ );
app.get( “/”, function (req, res) );
});
app.listen(3000, function (req, res) );

The default behavior of EJS is that it looks into the ‘views’ folder for the templates to render. So, let’s make a ‘views’ folder in our main node project folder and make a file named “home.ejs” which is to be served on some desired request in our node project. Filename: home.ejs

< html lang = "en" >
< head >
< meta charset = "UTF-8" >
< meta name = "viewport" content=
” width = device -width,
initial-scale = 1,0″>
< body >
< center >
< h2 >
Text from EJS variable passed
from server is =
< h2 style = "color:red" >
< br >
< h2 style = "color: blue;" >
Text from EJS variable passed
from script tag =
< h2 style = "color: blue;"
id = “text_from_script” >
< br >
< h2 style = "color: green;" >
Text from EJS variable passed from
script tag after manipulation =
< h2 style = "color: green;"
id = “text_from_script_manipulated” >
< script >
let name = ‘ ‘
let heading = document
,getElementById(‘text_from_script’);
heading.innerText = name;
name = “Mr. ” + name;
let heading_man = document.getElementById(
‘text_from_script_manipulated’);
heading_man.innerText = name;
