Modern technologies must be included in a business that would like to expand. Fortunately, businesses now have a wide range of options to choose from with the constant developments in technology. 

 

Node.js is one such technology that is widely used. Various businesses have embraced the Node.js application framework to create their back-end tech stack. Among various businesses, the ed-tech sector is now increasingly adopting Node.js. 

 

If you are looking to hire node js developer, then read below to learn some basics about building a scalable and securable ed-tech website using Node.js:

The working of Node.js  

Node.js offers an interesting point of convergence between front-end and back-end technologies in terms of application stacks. Node.js improves JavaScript’s functionality so that it can run on the back-end, server-side portion of a web application architecture as well as for serverless architecture. JavaScript is generally used as a front-end, client-side web scripting language.

 

Node.js executes this by running on the server within its own runtime. The comparison of Node.js and Java, which both allow for the execution of applications within their own runtimes, is a useful comparison. Building apps or websites in the Node.js ecosystem is made much simpler by the lightweight, efficient Node.js runtime’s non-blocking I/O and package manager.

 

The Node.js package manager is known as npm. Its function is to act as an index of the Node.js developer community’s libraries that can be quickly shared and imported by other projects.

These packages offer beneficial fixes for usual functions and lines of code that make it easier to build fresh projects and enhance existing ones.

Basics of Node.js:

The V8 engine is the foundation of Node.js, and it enables programmers to create server-side JavaScript applications. These are the basic Node.js ideas that will be followed when you hire node js developer to build an edu-tech website:

 

• Knowing about the Node.js architecture: As Node.js uses an event-driven, non-blocking I/O model, it can handle a large number of concurrent requests without affecting the execution of subsequent requests. To control callbacks and handle I/O operations, Node.js uses an event loop. 

 

• Installing Node.js: Installing Node.js is simple and can be done either by downloading the binary from the Node.js website or by using a package manager. Node.js can be configured using the command-line interface after installation.

 

• Node.js modules: Node.js uses modules to categorize functionality and organize code. The required function can be used to load a module into another module or script. These modules are basically reusable blocks of code.

 

• Asynchronous programming in Node.js: It is a fundamental feature that enables programmers to create non-blocking code. Callbacks, promises, and async/await are just a few of the techniques that Node.js offers for dealing with asynchronous operations.

 

Node.js is effective at handling enormous amounts of requests because of its event-driven, non-blocking I/O paradigm. Its modules and asynchronous programming capabilities keep your code clean and manageable.

Steps to build a scalable ed-tech website

These are the important scalable steps that will be followed by developers when you hire node js experts for building a website:

 

1. Rendering HTML in the browser

Developers have the option of sending some HTML rather than plain text when a route is accessed. Even the files that need to be transferred can be specified, and the HTML files can be manually created. However, it is helpful to create the HTML files using a template engine.

 

With the use of a template engine, developers can provide the templates for the application and replace the variables for real values during runtime. Then the template can converge into an actual HTML file that is then sent to the client.

2. Pug basics

The first thing to know about Pug is that there are no closing tags, and the indentation is used to explain the template’s structure. Elements must be indented one level to be nested.

3. Creating website

The keyword block enables programmers to extend a template through inheritance while building websites. Custom content for any block can be specified in the parent template when extending a template.

 

Any template that extends the default template must pass the default template’s title variable when rendering the template.

4. Using JSON data

The website’s pages can be built using the JSON file that is located in the root folder. On closer inspection, you will find a profile key, which is nothing more than an array of a few items, each of which denotes a profile. Usually, a database will be accessed to retrieve the data.

You must provide the index template with the JSON data while building the website and proceed as necessary. To build a user-friendly and responsive website, JSON data usage with the template is required. Both SQL and NoSQL databases, such as MongoDB, can be used with JavaScript without any issues.

Node.js security best practices

Securing your website is the most important factor after developing it, so when you hire node js programmers, they will follow these steps for security:

1. Use lint plugins

When you implement Node.js code, linter plugins like eslint-plugin security can help find security plugins and vulnerabilities.

2. Stop SQL Injections

The chances of database manipulation rise when you use JS strings or string concatenations. Your information becomes invalid because of this, and SQL injection attacks on the website become very likely.

For ORMs like Sequelize and Mongoose, built-in security against certain SQL injection threats is available. To protect against these attacks, you should always use database libraries that enable indexed parameterized queries or built-in indexed parameterized queries offered by Object-Relational Mapping/Object Document Mapper.

3. Installing logging and monitoring

For continuous security in Node.js, logging and monitoring are important. By keeping an eye on your logs, you can gain knowledge of what is happening in your application and look into any suspicious activity. 

4. Make sure you have effective authentication procedures in place.

You may have observed that a number of potential attacks may come from an evil actor who exploits or bypasses user authentication. A crucial defense against these attacks is having robust authentication mechanisms in place.

Final thoughts

If you are looking to hire remote node js developer, then knowing about these recommended practices can be beneficial. Therefore a quick and secure increase in your ed-tech website performance depends on which backend technology you select for your project as well as by following secure and scalable coding best practices.
