Node js apache- Full Guide 2022

Hey readers, in this article, we will be covering all about apache in Node js and its working along with examples. Before jumping directly to the working part, we will learn about Node js and the basics of what exactly apache is in Node js. So if you are new to all these concepts, don’t worry, we will be covering it right from the fundamentals and will then move to differences. So keep reading.

Introduction

It is an open-source organization and it provides a runtime environment for running JavaScript code beyond your browser. It is not a framework neither it is a programming language. It is mostly used in the backend for building  API services, accessing databases, etc.

Node js helps developers build large complex applications with ease by using microservices. It can handle thousands of requests coming to the server without slowing down the system. Using microservices in Node js, one can easily scale a large-scale system and can divide it into different chunks for feature updates. It helps add independent features to the application without changing other services.

It is largely used by developers in the backend of an application. Due to its non-blocking I/O and asynchronous nature, it has become the primary language used on the server side. Tech giants like Netflix, PayPal, Linkedin, and Uber use it for building API and servers. 

Uses case:

• API server
• Data streaming
• Microservices
• Building Real-time applications

Applications:

Both tech stacks are being widely used for developing web apps. Large tech giants like Netflix, Airbnb, and Instagram use this tech stack in their applications.

Why do developers use Node js?

Following are the reasons for choosing Node js over other backend languages:

• Easy to learn as it uses JavaScript
• Used for agile development and prototyping
• Provides fast and scalable services
• Asynchronous nature
• Uses “Single-threaded-event-loop” architecture

Node js apache

Configuring Apache for Node.js has a number of advantages.

For Node apps, it provides three key advantages:

• Caching
• Load balancing is a term used to describe the process of balancing
• The proxy server in the reverse
• Let’s look at each benefit’s use case.

Caching in apache

When an app’s content loads rapidly, it’s more likely to keep users engaged. Caching increases an application’s performance by reducing bandwidth usage and increasing speed. Caching is required if a Node application receives several requests for the same static material at the same time.

We enable the Apache server to install static content by configuring Apache for a Node application. Future queries for the same content will receive a response straight from Apache, rather than the application’s server.

Load balancing

It is a term used to describe the process of balancing

Even as it scales, high-performing software must remain accessible to consumers. By dispersing incoming requests over multiple servers, load balancing enhances the responsiveness of a program. Thousands of requests per second may be received by a popular app. We enable Apache to spread numerous events across all servers in the application by configuring Apache for a Node application.

The proxy server in the reverse

It’s critical to secure your application from viruses, malware, and other cyber threats. Apache can be set to function as a firewall or filter for all incoming requests using reverse proxy. Some security issues, such as DDoS attacks, can be mitigated by the reverse proxy. Improved user request management and encryption of the application’s IP address and data are further advantages of a reverse proxy.

Let’s install and start the Apache server now that we’ve gone over the advantages of employing one.

The Apache server is installed and started.

To begin, run the following command to see if it is already installed on our system:

apache2 -v

This will show you the Apache version that is presently installed.

Reviewing the Apache server’s fundamental commands

Restart the Apache server by doing the following: sudo systemctl restart apache2

After adding a configuration, restart the server using the command: sudo systemctl reload apache2

Disable the Apache server from automatically starting when the computer is rebooted: sudo systemctl disable apache2

After you’ve disabled the Apache server, you’ll need to re-enable it: sudo systemctl enable apache2

Conclusion

In this post, we looked at some of the advantages of the Apache server, as well as some fundamental instructions. We also showed how to increase the efficiency and security of a Node application by configuring the Apache server. Additional information, tips, and techniques can be found in the Apache server documentation and Wiki.
