Migrate Your App from AngularJS to ReactJS

AngularJS was released in 2009 and back then, it was the only viable tool to develop single page applications (SPAs). By the time React came in 2013, web developers were fed up with its slow pace of development and were looking for an alternative. Angular did not release a new version until 2016. Meanwhile, a majority of AngularJS developers moved to React. AngularJS is in three years of long-term support (LTS) as of 2018.

Migrate your App to React

AngularJS is an Obsolete Technology and isn’t up for Modern Web Applications

While AngularJS was an excellent framework when it was launched, it no longer carries the same amount of credibility due of performance issues, complicated architecture, absence of new features, lack of resources, and a fading community.


No Upgrade Path

When Angular 2 replaced AngularJS in 2016, every business wanted to secure the official upgrade path to update their application, except there wasn’t any.


Security Risks

When AngularJS will go out of support in the mid-2021, your applications built in the technology will be exposed to security risks and zero-day vulnerabilities.


Lack of Human Resources

Most of the developers who started as AngularJS developers have upgraded their skills & moved to a better technology. You’re unlikely to find developers to fix bugs.


Absence of SSR

AngularJS doesn’t support server-side rendering (SSR) of JavaScript and thus, the application relies entirely on the user web browser to render JavaScript code.


Limited Integration

AngularJS being an old technology, lacks compatibility with modern web services. Businesses requiring apps to run third party services will be disappointed.


Too much HTML

Today, businesses are too much invested in JavaScript. AngularJS is HTML-centric rather than JS-centric. JavaScript is far more robust, simple and consistent than HTML.

ReactJS is the Future of JavaScript Development and the Path to Upgrade your Application

According to a JS framework comparison, React is regularly used by 53%, while 32% plan to learn it. An open source project is as good as the community backing it. At TOPS, we recommend upgrading your AngularJS application to React for the following reasons.

Facebook is Committed
to the Project

Businesses who invested into React are apprehensive how the future will hold if Facebook pulls support out of the project. They don’t want the AngularJS debacle to repeat. Well, Facebook and a ton of major developers are committed to the open-source project.

React is Securest Way to Develop
JavaScript Application

The React community rather than concentrating on major releases insists on minor releases. Minor releases contain security patches to combat any prevailing security issue. Unlike AngularJS, React is safe from cross-site scripting since it doesn’t generate HTML strings.

React has a Huge Pool
of Developers

React is an emerging JS library growing at an unprecedented rate. This growth derived larger developer interest in the JS library and the rising demand from startups and enterprises has completed the cycle, making React the most compelling solution to build single page applications on.

React Code Runs Server-side
and Client-side

React gives flexibility to run the application code either client-side or server-side. The proposition made for applications with either great server configurations or capable user devices. Also, SSR allows applications to be crawled by the search engines and, thus, appear on the search results.

React is JavaScript, Left,
Right, and Center

React applications run JSX code, which is more JavaScript than HTML. Unlike traditional web frameworks including AngularJS where JS is inserted into HTML, JSX is a JavaScript syntax that allows HTML quotes and convention of HTML tag syntax for rendering subcomponents.

React is a Vast

One of the reasons for the larger developers’ interest into React is its vast ecosystem. Developers can expand what core React library can do by means of additional libraries. You can add new features by adding a package from the ecosystem, without upgrading the core package.

React Ecosystem Accelerates Prospects Around SPA development

Rely on Our Expertise in React for a Seamless Development Experience

Controlled DOM Manipulation

Extensive DOM manipulation in AngularJS applications is a known bottleneck. We solved the problem with React’s Virtual DOM, which acts as a layer between the user layer and actual DOM.

Go JS-centric from being HTML-centric

AngularJS relies too much on HTML templates. In JSX, HTML is inserted into blocks of JS code making debugging easier with error codes and warnings, which reduces your apps’ time to market.

Components, rather than Template

While HTML templates are easier to work with, we depreciate templates when upgrading your app to React. We break UI into independent components to deliver ultimate single page experience.

SEO Friendly SPAs with SSR

Google crawlers return a blank page upon rendering a block of JS code. SSR makes JavaScript comprehensible to Google Crawlers. We insist on SSR when migrating to React to make them searchable.

Confused, Which the Right Path to Upgrade your AngularJS Application

Upgrade your AngularJS Application to the Latest version of React with TOPS

Long-term support for AngularJS will conclude in mid-2021, which will expose your AngularJS application to security threats and zero-day vulnerabilities, limit its community, and deprive it from modern features. TOPS has the adequate resources to make the necessary measures to upgrade your AngularJS application to the latest version of React. TOPS has a dual approach to the entire process of application upgradation.

Parallel Development

  • In parallel development, we try to create an exact replica of the AngularJS application in React. The process starts with our developers examining the app to determine what we can reuse and we have to write from scratch.
  • Once that is established, we communicate the deadline, cost, and other crucial detail of the project to you. Your AngularJS application will remain intact, unless the React application is ready for production.

Sequential Development

  • Sequential development is bit more challenging than parallel development. In this sort of development, we divide the application into many smaller modules representation one or more application features.
  • Then we enter in consecutive stages of sequential development, wherein our developers write a ReactJS code to replace the existing AngularJS module on the live application. It’s challenging because you’re replacing components of a moving car.
