The Embedded JavaScript (EJS) is a widely used template engine in web development. It enables developers to generate dynamic HTML content by embedding JavaScript code within HTML templates.
Example usage
- Install dependencies
npm i ejs express- Set up Express application
const express = require("express");
const path = require("path");
const app = express();
const port = 3000;
// serving static assets
app.use(express.static(path.join(__dirname, "public")));
app.set("view engine", "ejs");
app.set("views", path.join(__dirname, "/views"));
app.get("/", (req, res) => {
res.render("index", { message: "Hello, World!" });
});
// start the server
app.listen(port, () => {
console.log(`Server is running on http://localhost:${port}`)
