express ejs
To use Express with EJS, you can follow these steps:
Install Express and EJS: Start by installing both Express and EJS packages using npm. Open your terminal and run the following command:
npm install express ejs
Import modules: In your JavaScript file, import the necessary modules. Add the following lines of code at the top of your file:
javascript const express = require('express'); const app = express(); const ejs = require('ejs');
Set the view engine: Configure Express to use EJS as the view engine by adding the following line of code:
javascript app.set('view engine', 'ejs');
Define routes: Create the routes for your application. You can define routes using the
app.get()
orapp.post()
methods. For example:javascript app.get('/', (req, res) => { res.render('index'); });
Create EJS templates: Create the EJS templates for your application. These templates will be stored in a folder named "views" by default. For example, create a file named "index.ejs" in the "views" folder and add your HTML code with EJS syntax. You can use EJS tags like
<% %>
,<%= %>
, and<%- %>
to embed JavaScript code and variables.Render views: Inside your route handler, use the
res.render()
method to render the EJS views. Pass the name of the EJS file as an argument. For example:javascript app.get('/', (req, res) => { res.render('index'); });
Start the server: Finally, start the server by adding the following line of code at the end of your file:
javascript app.listen(3000, () => { console.log('Server started on port 3000'); });
That's it! You have successfully set up Express with EJS. Now, when you navigate to the specified routes, Express will render the corresponding EJS templates.
