By Vikas Sharma | 0 Comments

Not everyone wants a website on a CMS platform. Some of us want our own website development server built from scratch. For that, you need a good website development company in UK to build a server using node.js. Building a backend using Node.js doesn’t take that long. If you know programming, then working with Node.js with the help of our guide will be easy. Let’s understand from the beginning.  

What is Node.js?

Node.js is a JavaScript runtime environment. It easily builds fast as well as scalable applications. It runs the JavaScript code on the server-side and hence, produces dynamic web content. Various modules are present in Node.js, for instance, HTTP and request. 

How Do Servers Work?

Do you know what a server is? When you search for anything on the net, the request goes to another computer which gives your required webpage as the output. That computer is called a web server. The web server, thus, receives HTTP requests from clients and accordingly, produces an HTTP response. Node.js helps us to write this server code. Thus, over time. Node.js has become the most popular choice for developers to write backend code.

How To Install Node.js?

First, you need to install the Node.js framework. Here’s how you go about it:

1.  Download Node.js Installer for your Windows OS.
2. Run the installation.
3. Start the installation.
4. Test the following command in your Command Prompt to check the updated version: $ node -v.

 

Build The Server Using Node.js

We are using Visual Studio Code for our project. Here’s how you go about it:

• Create the project folder using the required command:

Create your project folder using the following command. mkdir node-server-tutorial

• Inside the folder, make a file and name it server.js

Use the HTTP module to write the server.js file. // server.js var http = require('http'); var server = http.createServer(function(req, res) {     res.writeHead(200, { "Content-type": "text/plain" });     res.end("Hello world\n"); }); server.listen(3000, function() {server.js file,      console.log('Server is running at 3000') });

• “Require http” code needs you to have the HTTP module in your file.
• We have created the server using the method createServer.
• The method takes request and response parameters.
• A response is sent to the client.
• The application runs at port 3000.

• Run the Node.js server

Now that you have written the node.js file, it is time to run the Node.js server. In the terminal, write ‘node server’. Now, open your preferred browser and go to http://localhost:3000 since our application is running at port 3000. Hurray! A plain text shows Hello World, the response we had sent in our server.js file.

• Now, install the express framework

• Go to your terminal and write ‘npm init'.
• Now install the express framework.

 npm install express –save

• Now we will write the code using the express module and two commands: get() and listen()

// server.js var express = require('express'); var app = express(); var PORT = 3000; app.get('/', function(req, res) {     res.status(200).send('Hello world'); }); app.listen(PORT, function() {     console.log('Server is running on PORT:',PORT); }); After completing the above steps, you start the server again. Finally, your Node.js server is complete. Also Read :

Build Your eLearning Websites like W3 Schools or Coursera

By WNW SEO | 0 Comments

When all educational institutions went online, all students in the world got an experience of eLearning. This has undoubtedly given rise to platforms like W3 Schools and Coursera. One of the main reasons why they work is because they have built their website very strategically. You need the best web development company to build a platform that has so many features.

7 Easy Ways to Build Your eLearning Websites like W3 Schools or Coursera

So, how would you like to build your website? Let’s see what all you need to create an eLearning website:

1.   A Well-Defined Model and Structure

Usually, a website will contain either of the above 3 models. If you want to provide your own self-learning courses and certificates, then you need to brand yourself accordingly. And if you want to tie-up with other professionals – be it individuals or educational organizations, then you need to target two markets – the tutors through which your website will run and the students who will bring in the revenue.

2.   Learning Management System

Online course material usually comprises of e-books, videos, quizzes and other interactive learning content, all of which should be available only to paid subscribers. At the same time, the certificate can only be made available once the user has completed the course. To ensure the smooth and foolproof operations, you need a learning management system – a software application used to automate the entire process.

3.   Video Hosting Platform

An eLearning website consists of paid courses only. Whether you are providing your own tutorials or providing it through tutors, you need to ensure that only students who have paid for the course are allowed access to the videos. Hence, you need a plugin or a self-coded video hosting platform that is secure, light and functions properly.

4.   Ecommerce Integration

In the end, people are buying a course here – which is entirely a virtual product in itself. So, you need to integrate payment gateways and add other shopping features that can facilitate online purchases for users. If you’re creating a WordPress website, you can use WooCommerce. Other popular platforms include Edwiser Bridge Bundle, LMScheckout, Course Merchant, Arlo and Enrolmart.

5.   Using a Course Builder

This is a software that enables you to create an interactive online course. You can provide with the course title, description, featured image, pdf files, video files, quizzes, assignments and certificate of completion. With advanced features, you can ensure that all the files can be accessed in a certain order only. Additional details that you can provide include difficulty level, number of students enrolled, and tutor details.

6.   Focus on UI/UX is Very Important

If you see the UI/UX of Coursera or W3 Schools, you’ll see how simple it is for anyone to understand the course they can take up. Providing advanced features such as filters, easy sign-up, admin panel and multiple payment options is helpful. You need the best web development company to help you here.

7.   Providing 24x7 Online Support

If you have a business model similar to Udemy or Coursera, you’ll need two support teams – one for tutors and the other for students. While the option of live chat can always be there for all, you additionally can keep a contact form for a longer query. Creating an eLearning platform requires additional features that a regular website doesn’t have. Thus, you need the best web development company to do the job for you.
