Choosing React Over Angular: What You Will Gonna Lose?

In this article "What you gonna lose if you choose react over angular" I will spot some of the features that make angular unique and stand out from other frameworks and this article not meant to compare react with angular there are already tons of articles or blog posts doing this, but in my opinion, if you choose x over y you gonna lose something so I wrote this article to guide you throw the features you gonna lose if you choose react over angular and finnaly you are free to choose whatever you want but remember you gonna lose something 😉.

Before we start I know many of these features can add to react using the community libraries, but this approach came with many issues like 

  • The library not updated to match last version of react.
  • Library's author decides to remove it.
  • Maybe react upgrade itself making the library obsolete.

DI (Dependency injection)

Without a doubt Dependency injection is one of stand alone feature distinguished angular from other frameworks or library so I make it on the top of the list.

So what is Dependency injection?

In software engineering, dependency injection is a technique in which an object receives other objects that it depends on. These other objects are called dependencies. In the typical "using" relationship the receiving object is called a client and the passed object is called a service.

What Dependency injection in angular offers?

  • Singleton class (restricts the instantiation of a class to one "single" instance).
  • Easy to unit-test (you will pass the needed objects to the constructor).
  • Sharing state between components.
  • Sharing functionality through the app.

What react offers similar to Dependency injection in angular?

For sharing state react has a context, which provides a way to pass data through the component tree without having to pass props down manually at every level. This doesn't solve the scope issue after all context are global state and limited only to sharing state.

For sharing functionality you can use class but if you want it a singleton class or loaded it when you need it like angular you gonna build it with your self as react team doesn't provide such a solution for this problem.

Multi-Files component or single file component

Angular doesn't have restrictions to wrote your angular component in one file or multi files one for html, one for css and one for javascript, on the other hand, react force you to write your html with jsx syntax inside render function which is ok if the component very small and doesn't have a lot of logic attached to it but it will become a pain in ahead once that component scale up leaving you with readability issue.

Scoped CSS

Angular provides embedded solutions for scope css which is a very critical and essential feature if you want to build a reusable styled component, on the other hand, react team doesn't provide or recommend a solution and once again leaving you to decide whether you built your own solutions or stick with the various options to pick up one of them.

No Slandered HTML 😢

Surprise, JSX is not html and you can not use some attributes in html directly for example 

 I know it is not a big deal but it counts, and this leads us to another section.

Web Components not fully supported in react

I'm not going to explain what is Web Components please check this link for more details.

According to react documentation

"React and Web Components are built to solve different problems. Web Components provide strong encapsulation for reusable components, while React provides a declarative library that keeps the DOM in sync with your data. The two goals are complementary. As a developer, you are free to use React in your Web Components, or to use Web Components in React, or both."

This is sweet, but it is not completely honest for example according to the same documentation if you gonna use video tag for example and wat to listen to play or pause event from the dom you will need to use a ref to interact with the DOM node directly, it is like jquery old days.

React team recommended to warp the web component with react component just to make it work another workaround for the limitation.

Forms, Forms, and Forms 😁

There is no web app or websites nowadays doesn't have form or at least a search bar and I think reactive form is one of the shining features exist only in angular solved many problems related to forms in an elegant and extendable way, this amazing feature makes build complex form super easy, easy to maintain and easy to customize. On the other hand, react team doesn't provide any solutions for just common forms problem and make it for developer decision and that leads to the lake of solutions out there and a lot of them are very opinionated and many of them solving part of the problem.

Example: angular reactive form (Login Form)

    const form = new FormGroup({
      email: new FormControl('', [
      password: new FormControl('', [
        noWhitespaceValidator // custom validator

    onSubmit() {
        if (this.form.valid) {
            const formValue = form.value; // get the form data
            // call the server or do what you want
            // ...
<form [formGroup]="form" (ngSubmit)="onSubmit()" autocomplete="off">


  <button mat-button type="submit">Login!</button>

As you can see it is very easy to maintain, read, and more reasonable, I'm not going to explain reactive form in detail but here is a list of what makes it stand out features.

  • Reactive forms provide a model driven approach to handling form inputs whose values change over time.
  • Reactive inputs are observables.
  • Custom validators.
  • Async Validators (for example: checking with server side if username available or not).
  • Complex validator (for example: checking if renter password input matching password input).

Angular CLI

Angular CLI is not schofield generator or scripts running only it is beyond that and here are some the features.

  • Generate components files directly from cli with pre filling data as you configured in cmd
  • Upgrade your angular project with one command.
  • Create your own generates using Angular schematics.
  • Support sass, less and stylus out of the box no need for extra setup or edit or eject web pack configurations.


A lot of people are more interested in what they will lose, rather than what they will earn so that they will not regret the decision. It is like a trade-off you gonna win and lose there are no perfect solutions for all the problems either in life or in programming but after listing those features you can see the angular framework using regular html so most of solutions and features exist to enhance the web platform, on the other hand, react focus on keeping data in sync with ui.
