Why i won't use React Hooks

revskill10 profile image Truong Hoang Dung ・1 min read

I'm passionate about ReactJS, because of its declarative programming model.

That means, in React,

view = function(state)

That's why i never mess React Component with side-effects, like ajax request or state.

With separate function for behaviour, you can easily reuse, unit test, and package it.

With React Hooks, what i have to do is to mess side-effects within the component.

It's not good to me.
It's not simple to debug.
It's not simple to reuse the behaviour.
It's not easy to unit test the behaviour.

That's why i would say NO to React hooks, because i prefer simplicity to magic.
I'm a simple developer, not a magician trying to understand wtf is going on with my production code.

I can understand your concerns. Though at the same time, hooks are just an upgrade for the lifecycle functions of class components or the HOC's, but they make it simpler, so if you used those, there's no reason you shouldn't use hooks. I find that hooks look clearer than HOC's or lifecycle functions (HOC's would just always confuse me when I have to compose them, especially when I'd try to create props typings).

I get though that you want to keep your components as much functional as possible. Personally, I started separating my components into containers and views. Views have nothing async, zero side effects, just props => ReactElement. All the data loading and state management and side effects happen in containers. Even when I switch to hooks, it will stay that way.

 

I didn't get familiar with hooks, but it seems React team is sometimes pushing it too far, the need to innovate, and the question remains, whether there was really a need for it, or not.

 

Agree. I found no need for React Hooks.

 

Couldn't agree more. Sometimes, I wonder if they just add the hooks just for the sake of making it different and stand out from other libraries out there.

 

Yet you have a post on 'A React Hook for universal routing' xD
yeah seems like React team is stretching it too far with react hooks . not a fan YET :)

 

Yeah, i was wrong at the time of the post. I comeback and retry and i was hooked :P

 

Your article is well ranked on "react hooks community reaction" (yes, I did search for that before joining the band wagon). So, I think you could update this article with your newer finding about react hooks.
BR.

 

That's why i never mess React Component with side-effects, like ajax request or state.

How do you do it then?

 

You can use a HOC (Higher order component) to reuse behaviour, or using Render Props pattern.

 

No need for redux.
You can read more about HOC and render props in ReactJS guide.

 

I guess that's okay, it's exactly why the React team isn't making classes and HOC's go away :) Personally, I feel that hooks are more in the "spirit of React", but at the same time, the spirit of React is to have more than 1 way to do things, so this is just some healthy variety

 

Totally agree with. I also posted a question against it.
