Make 404 page for user goes to invalid page

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 Here, 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 404 or not found page?

Why i am sharing this blog. you are all aware about our previous blog where we have to written without extension page name visible but there we have to add some extra efforts ge. User will easily detect which technology we have used.

Let's code

Here we will write first not found html page in public folder (404.html). Then we have to write one more line code in index.js

app.get('*',(__,resp) => {
    resp.sendFile(`${publicPath}/404.html`)
})

Whole Code

const express = require('express')
const path = require('path')

const app = express();

const publicPath = path.join(__dirname, 'public');


app.get('',(__,resp) => {
    resp.sendFile(`${publicPath}/home.html`)
   
})

app.get('/about',(__,resp) => {
    resp.sendFile(`${publicPath}/about.html`)
})

app.get('/contact',(__,resp) => {
    resp.sendFile(`${publicPath}/contact.html`)
})


app.get('*',(__,resp) => {
    resp.sendFile(`${publicPath}/404.html`)
})



app.listen(5000)
