Can context API replace Redux?
But now it’s possible to replace Redux with React Hooks and the Context API. In this tutorial, you’re going to learn a new way of handling state in your React projects, without writing excessive code or installing a bunch of libraries — as is the case with Redux.
Should I use Context API?
Context is primarily used when some data needs to be accessible by many components at different nesting levels. Apply it sparingly because it makes component reuse more difficult. If you only want to avoid passing some props through many levels, component composition is often a simpler solution than context.
Is Context API deprecated?
Note: The legacy context API will be removed in a future major version. Use the new context API introduced with version 16.3.
Does react Redux use Context API?
React-Redux allows any React component in the application to talk to the Redux store. This is only possible because React-Redux uses Context internally.
What is the downside of context API?
The problem with context is simple: Everything that consumes a context re-renders everytime that context’s state changes. That means that if you’re consuming your context all over the place in your app, or worse, using one context for your entire app’s state, you’re causing a ton of re-renders all over the place!
How can I avoid component reuse problem with context API?
If you need to have some data accessible by many components at different nesting levels, then you should use the Context API. React docs advises that we ‘apply it sparingly because it makes component reuse more difficult. ‘ In other words, you might not be able to reuse your components ‘out of context’.
Can I use both Redux and context API?
If you’re looking for a big store where you can dynamically manage data and constantly update it, Redux is the way. If you need both, my opinion is that it’s perfectly okay to do so.
What is the difference between react Context API and Redux?
The React Context API introduced with React 16.3. React Context API is a built function that enables sharing of data with nested components. One major difference is comparing to Redux it is built into React and does not require any additional library installations.
Do I need to use Redux?
The latest Context API can be used for Applications where you would simply be using Redux to pass data between component, however application which use centralised data and handle API request in Action creators using redux-thunkor redux-sagastill would need redux.
What is the difference between Redux connect and context consumer?
A context doesn’t retain anything; it merely distributes the data you pass in. Redux’s connect function is a higher-order component (or HoC for short). It wraps another component and passes props into it. The context Consumer, by contrast, expects the child component to be a function.
What are the best resources to learn about Context API?
If you have a subscription to egghead.io you might enjoy my course on the Context API over there. It’s only about 35 minutes long and covers a lot of ground: how to manage state with Context (without Redux), patterns for structuring your code, how to display notifications, testing, performance.
