Overview of using React to build a SaaS

SaaS, the term stands for software as a service, was initially introduced in the 1960s and gained worldwide popularity in the early 2000s. In today’s world, SaaS in React has become the ultimate trend. Thanks to Netflix, Spotify, Dropbox, and other amazing apps made SaaS famous to a much larger audience.

Statista says that by 2025, SaaS is to become the most intensive form of Software development in less than three years. Its market value is to cross $37,150 Million by 2025, more than all other kinds of software development combined.

The infographic below offers insights into the projected market revenue of SaaS compared to other sorts of software development. Have a look:

When developing SaaS applications, it’s essential to understand what makes one platform better than another. React is becoming the most preferred choice for SaaS application development. So, if you’re looking to build or develop an application, you may be wondering:

  • What is Reactjs used for?
  • Why is SaaS in React becoming a popular choice?

React is one of the top frontend JS libraries in the past few years and holds massive popularity of 40%.

It receives constant support & active development by Facebook engineers, ensuring that React JS keeps pace with modern web trends & challenges. Due to these reasons, SaaS developers often choose React over their immediate competitors, including Angular 2, Vue JS, etc.

1. Immutability in JavaScript:

The basic working principle of React is about generating immutable data, which helps to create a new state without modifying its previous one. This feature makes it highly scalable.

2. Unified Application Structure:

Unlike most other frontend frameworks, everything has to do with components. There are no particular concerns for handling data, server communication, etc. It gives a single structure across all platforms, making them easy to understand and maintain.

3. Virtual DOM

Using it helps ReactJS developers create a fast web application while maintaining its accuracy at every user’s click or keystroke.

4. Asynchronous Communication with Server Using Flux Pattern

The pattern used in ReactJS helps developers create applications that asynchronously communicate with a server, avoiding issues like blocking and executing several codes at once. It also makes it easier to change data on the server without impacting UI elements, enabling a developer to make changes quickly and fix errors before they occur.

5. Declarative Approach

You have to define what a UI element should look like instead of explaining how to build it. It makes it easier for the developers as well as users.

6. The Use Of One-way Data Binding

Most other popular frontend frameworks use two-way data binding that updates UI and changes user input without any confirmation from the user, leading to confusion in some cases.

However, with one-way data binding, if an unexpected change occurs due to an error on the server or any other means, react immediately shows users about changes using its virtual DOM. It then updates data sources when they are satisfied with changes through JavaScript code.

This feature helps web applications run smoothly but still allows programmers to make modifications where necessary.

7. Component-Based Architecture

Since everything in React application revolves around components, it makes it easy to understand code and reuse them for future projects.

For example, suppose you’re working on a project and need to add similar functionality later instead of rewriting all features from scratch. In that case, you can develop a new component and use it again with slight modifications where necessary.

There are no separate responsibilities or controls in ReactJS applications. Unlike most other frameworks, there’s only one way of doing things, making it easy to use components even by people with limited programming skills or are still learning.

8. Dependency Injection

For adding dependencies like a third-party API, it’s not necessary to extend other components or change their state. It makes it easier for any developer working on a project to make changes without affecting existing code. It also allows developers working on different sections of an application to work independently & share components that work well with one another.

9. Easy Debugging With Component Lifecycle Methods

Using component lifecycle methods, developers can easily control which actions or variables should be in effect at what point in time during the component rendering process without having to resort to calling multiple functions.
