Node js vs Angular: Which one is better?

I am a Web Developer and have worked with lots of javascript libraries and frameworks. One of the most common questions that I hear from beginners is what is the difference between Node.js and Angular. There are so many libraries and frameworks for web development, getting lost among them is quite easy. I hope this article helps you in understanding how Node.js and Angular are different. To understand better I would recommend you start with Introduction to Web Development.

Node.js is used for building back-end services and is not a programming language or a framework. On the other hand, Angular.js is a frontend javascript framework. Comparing Node.js with Angular would be fundamentally wrong. If you want to build a web application you will need both back-end services and front-end. The most common frontend javascript libraries and frameworks are Angular, React, Vue, and Next.

What is Node.js?

Before 2009, we used Javascript only to build applications that run inside a web browser. But Node.js has allowed javascript to run outside the web browser. Node.js uses the javascript execution engine developed by Google Chrome. Each web browser has developed a different javascript execution engine. Mozilla Firefox developed SpiderMonkey, Microsoft Edge developed Chakra, and Google Chrome developed V8. The creator of node (Ryan Dahl) took Google’s V8 engine and embedded it inside a C++ program and called that program Node.

Node.js is an open-source runtime environment for executing javascript code outside of a browser. We often use Node to build back-end services called APIs (Application Programming Services). Node.js is ideal for building highly-scalable, data-intensive, and real-time apps that power client applications. Click to download Node.js

What’s so special about Node.js?

Node is easy to get started and can be used for prototyping and agile development. It can also be used for building super fast and highly scalable services. Large companies such as Uber, Netflix, PayPal, Walmart, etc use node.js for building back-end services. In fact, PayPal rebuild their java and spring based application using node and found that node application was built twice as fast with fewer people in 33% fewer lines of code and 40% fewer files. More importantly, they doubled the number of requests served per second, while decreasing the average response time by 35%. Which makes Node.js an excellent choice for building highly scalable services. It also has one of the largest ecosystem of open-sourced libraries available to you.

What is Angular?

Angular is a framework built by Google for building client (front-end) applications using HTML, CSS, and Javascript/TypeScript. Angular had a previous version called Angular.js which was created in 2009. It was a pure javascript framework and was discontinued on December 31, 2021. TypeScript is more common in the angular community because angular itself is written in typescript.

Benefits of using Angular

• Data Binding – Angular offers four ways of data binding (One-Way, Two-Way, Event, and Property).
• Supports Cross-Platform Applications – Since angular moved to typescript, it helped angular developers move closer to mobile development. As TypeScript is also used in nativescript developers are able to port up to 90% of code from web applications to mobile applications.
• Clean Structure – It gives a clean and loosely coupled structure that is easy to understand and maintain.
• Reusable Code – Angular brings in lots of utility code and is component-based just like react which allows developers to reuse the same components.
• Easily Testable – We can write automated tests to test various parts of applications.
