Loop in ejs embedded javascript template
Hello viewers, whats up!! Here i am back again with the new series of Nodejs. Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to run JavaScript code outside of a web browser. It is built on the V8 JavaScript runtime engine, which is the same engine that powers the Google Chrome browser.
Node.js is commonly used for building APIs (Application Programming Interfaces). You can create RESTful APIs or GraphQL APIs using Node.js to handle HTTP requests and serve data to client applications.
Key features of Node.js include:
# Asynchronous - Node.js is designed to be asynchronous, meaning it can
handle a large number of concurrent connections without the need for
multithreading.
# Single-threaded, Non-blocking I/O -
Node.js uses a single-threaded event loop to manage asynchronous
operations.
# npm (Node Package Manager): npm is the default
package manager for Node.js, allowing developers to easily manage and install
libraries and dependencies for their projects.
# Server-Side Development: Node.js is commonly used for server-side development, where it excels at
handling real-time, data-intensive applications, such as chat applications,
online gaming, and streaming services.
But Why we are using Expressjs
, just because of incase if you want to make API using
nodejs directly then its a very complex method to create API and
integrate directly thats why we are using Expressjs framework and in
this framework with the help, you can create
RESTful API easily.
Why we need of EJS ?
Here we gonna discuss about ejs template because of you are all aware about our previous blog where we have to written static page name where we don't need to implement database and in static page for not possible but for this template you can Database connectivity with dynamic page.
How to Make loop in EJS?
First we will make object in index.js (we have already told you please check continuously visit our blog.
app.get('/profile',(__,resp) => {
const user = {
name: 'atul',
email: 'kumaratuljaiswal222@gmail.com',
city: 'hyderabad',
skills: ['php', 'js', 'reactjs', 'nodejs']
}
resp.render('profile', {user});
})
Here, we will consider app.get method and inside this method set as name whatever you want to set to parameter for url ('/profile). Then ( __, resp ) this line goes to define first parameter as a req or __ space after that response as a resp parameter.
After that written a const user object with property and last line goes to resp.render with rendering profile.ejs page and object name.
Whole Code (index.js)
const express = require('express')
const path = require('path')
const app = express();
const publicPath = path.join(__dirname, 'public');
app.set('view engine', 'ejs');
app.get('/profile',(__,resp) => {
const user = {
name: 'atul',
email: 'kumaratuljaiswal222@gmail.com',
city: 'hyderabad',
skills: ['php', 'js', 'reactjs', 'nodejs']
}
resp.render('profile', {user});
})
app.listen(5000)
Make loop in Profile page
<!DOCTYPE html>
<html lang="en">
<head>
<title>Profile Page (EJS)</title>
</head>
<body>
<h1>Welcome <%= user.name %></h1>
<!-- <h1>EmailID <%= user.email %></h1>
<h1>City <%= user.city %></h1>
-->
<% user.skills.forEach((item) => { %>
<li><%= item %></li>
<% }) %>
</body>
</html>
