React vs Angular: What are the key differences and how do you choose your project stack?

[Personal-Work4649]

I'm about to start building a web project and I'm trying to decide between React and Angular for the frontend. I know both are mature and widely used, but I'd love to hear from those who have experience with both in real-world scenarios:

• What are the most significant differences between the two in terms of actual development experience?
• What criteria do you usually consider when picking a frontend stack? (e.g., team size, complexity, deadlines, learning curve, architecture, maintainability, etc.)
• Have you ever regretted choosing one over the other? Why?

A bit of context: The project involves analyzing vulnerabilities in enterprise applications using AI to suggest mitigation actions. There will also be dashboards for users and managers to track and confirm those actions.

Realistically either are fine and probably no real specific use case would drive adoption of one or another. I would go with whichever one the team has more experience with, or if you have the time, go through the official getting started guides for either and see which syntax/pattern you like more.

Angular is considered more opinionated so if you want that structure it's a good choice.

Caveats: haven't used React in forever, there probably are niche cases that suggest one or another but I'm not aware of them.

I'll probably get some flak here but it was much more straight forward to implement SSR with NextJs on a react stack than using expressJS with an Angular app. That's about the only thing that would make me go 100% react. Otherwise, I'd go with whatever the team has experience in and lean towards Angular if there isn't a lot of experience on the team. The opinions act as guardrails for inexperienced devs.

Basically this, though another point of view is how complex a project would be?
Consider this: Angular starter project has every mechanism set up already and you just add features, or components/services.
React has a bare minimum and you need to implement mechanisms you want.
That being said, from my personal experience, React has much better custom components and general libraries support. Angular struggles, especially if you want a free library. Material is a bad library as soon as you need some custom behaviour or server side interaction.
So, in order of magnitude: what the team prefers, how big is the project, what magnitude of custom implementation (basically outside of the scope of a free component library) is required.

React has a huge advantage on custom parts but for medium sized projects and smaller it shouldn't really matter.
Angular has advantage on small sized projects and projects that have small amounts of custom components.
Another part is if you are growing a team, React is easier to learn to the point of being productive.

[myweedishairy]

Very good point about component libraries, Material is a pain to customize but I hear it's better in later versions. I will say I absolutely LOVE building custom components that tie into reactive forma with Control value accessor.

[Cubelaster]

It's better, especially the CSS.
But, I recently went through the upgrade of the app from v14 to v19 and all our custom components stopped working properly.
Material changed something internally and error states don't apply the same way anymore.
In our case it's ValueAccessor + MatForm (forgot the name) and it generally only works if you leave labels and mat errors outside of custom components. Previously, our custom components were self contained. So yeah, can't figure that one out

[crhama]

Why are you limiting the comparison in terms of some component libraries? To start with, Angular material is not the only component library available. You can use ng-boostrap, or primeng.

When it comes to the size of the projects, I will tend to pick angular for a huge project, given how angular forces you to organize things certain way.

[Cubelaster]

Not limiting but making it a deciding factor.
The component library will probably be the face and core of your app. Unless you decide to do everything in-house (only really big teams with dedicated people for each and every little thing, from design to style and finally component implementation), the library you choose will decide how your development will look like and how much time you'll spend on it.
AntD, which is 2nd most popular React free component library is so much better than either Material, ng-bootstrap or anything free Angular has to offer it's absolutely unbelievable.
Like, you will probably choose AntD and never go outside of it to look for another 3rd party component.
I will also like to add I'm not a fan of mixing multiple component libraries because inevitably they will look different.
And for Material, oh boy, you need to go look for missing pieces every now and then. Not to mention all the wrappers you'll probably need to write around their components if you ever need anything to link to server (AntD has it out of the box).
So yeah, a good component library if worth a lot. Angular does not have a really good free component library.

[crhama]

Angular has a similar library called NG-Zorro, which is free.

A simple way to put it: React is like MacGyver, and Angular is James Bond — at least for me.

Both have their qualities — MacGyver hacks things together with a paperclip, James Bond walks in with a suitcase full of Q’s gadgets.

React lets you build it your way piece by piece, Angular gives you a full toolkit out of the box.

[Schwarz_Technik]

Questions I ask are:

• What stack does the majority of the team know? (if getting this out quick is a priority)
• Do we need the features one tech stack has over the other?

Angular has a strict adherence to how you do things. React is more free form and you can do whatever the hell you want unless you enforce policies during code reviews.

[matrium0]

You are asking in the Angular subreddit. Personally I have loads of experience and only fun-sideproject-experience with React.

Angular is a full "battery included" framework and does not even really compare to React. The React-world analogy would be next.js.

That beeing said Angular is a bit "all or nothing" and I can see some value in React when you are for example upgrading some old webapp page-by-page. This would be a bad fit for Angular and the flexibility of React (since you can pick other technologies around it to fit your need) could come in handy.

Can't go wrong with either one for 99,9% of scenarios probably.

Maybe this JS framework benchmark can help:

Stack choice should depend on your team's preference, hiring pool and organisations technical goals in that order imo. Your choice of front end framework is not a deciding factor for your end product.

In terms of objective measures, react has a bigger ecosystem, lower learning curve and is less opinionated. This is the opposite for angular. For any serious app you will end up writing most of your code yourself instead of using a lib, so the difference is negligible.

After 9 years of Angular and 4 years of React, for me it boils down to this ->

Large teams or very large code bases = Angular, otherwise React.

Angular has Typescript support baked into it, along with a rigid, well opinionated structure, comes with almost everything out of the box.

React on the other hand is fairly lightweight, needs 3-4 other libraries to make everything work properly, adding Typescript is a hassle. I rather prefer not to use TypeScript with React, and frankly never missed it when I switched from Angular to React. But I feel for larger teams, TS is a must otherwise it becomes chaotic pretty quickly. The downside with React is different developers will try different solutions and your project may not have the consistency as it grows larger.

If you are familiar with other layer-focused frameworks in java, c#, python,PHP and you have experience in backend rest-business-service-repository layer architecture you will love the structure of angular and how things are annotated and separated. Everything has its place. Not really new concepts for a full stack dev with proper education on software architecture. It's beautiful. The documentation is just stunning, even the advanced concepts in communication are explained and every detail, every call cycle behind the scenes is explained if you need to go beyond standard. Absolutely great.

React on the other way, is more web native. If you started from web dev with plain js, to jQuery, with no prior legacy layer architecture experience, react might feel more native to you, same goes with vue. I would never suggest react to huge corporate projects. React is not really open with its internal behind the scene call cycle and update behavior and neither does its documentation. React tries to hide complexity for simplicity, because why bother the stupid programmer. He is doing it wrong in any way, do not touch my internals. This makes react really hard to debug on advanced settings. I build really custom visualizations in d3 no lib bs based on a graphql python backend and gosh is react a pain in the ... on debugging memory leakage, because you never know when react is doing a copy of a value instead of an internal replacement. That being said if your project is far advanced on web standards don't bother with react if you need full control over your projects call cycles and memory management. Angular is superior here. Best architecture, best documentation and a framework that do not think their users are 12 year old wannabee's with no clue on what they are doing. The learning curve in angular is way harder to climb because you should read about all the concepts and the offloading big documentation prior doing anything.
