Thus, stateless functional components programmatically enforce keeping the component pure. Since stateless functional components don’t support local states, you can’t easily hack into some state in a moment of laziness. See, it’s always tempting to add state to a presentational component when you’re in a hurry. Stateless functional components don’t support state or lifecycle methods. Instead, the state should be managed by higher-level “container” components, or via Flux/Redux/etc. Presentational components focus on the UI rather than behaviour, so it’s important to avoid using state in presentational components. Stateless functional components are useful for dumb/presentational components. Functional Components Enforced Best Practices Container Components use Class Components and concern state and behaviour.Ĭory House’s article React Stateless Functional Components: Nine Wins You Might Have Overlooked let me know the Functional Components’ advantages, Functional Components are more:įunctional Components are stateless, which is its limit.īut fortunately, most of the time, we don’t need a state.Presentational Components use Functional Components and are only concerned with the UI.We can also separate the components as Presentational Components and Container Components. Presentational Components are written as functional components unless they need state, lifecycle hooks, or performance optimizations.Įven though we don’t use Redux.
Redux’s creator Dan Abramov has written an article Presentational and Container Components: Presentational Components: concern about the UI.If we use Redux, there will be two kinds of Components: With react hooks, a functional component can also have a state.ġ. need to create an error boundary using componentDidCatch.You only need a class component when you:
We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you. I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. Unless you needįeatures available only in a class, we encourage you to use functional Can you give me some primary examples of the below of when you would want a specific feature of a class to make a component?Ī functional component is less powerful but is simpler, and acts likeĪ class component with just a single render() method. classes and reading from the docs they don’t really go into detail. I’m trying to understand when to use React functional components vs. All we need is an easy explanation of the problem, so here it is.
