JavaScript Redux form or simple form redux form simple example,redux form simple,react redux simple

Often in the interview questions it is heard that Why one should use redux form in the ReactJs instead of simple form. which extra ordinary facilities it provides to the developer ? Then what should be proper answer for this.

Answer:1

Now that is known why to keep the form data in the state and you reason if that makes sense for your application we can come back to our main subject. Given that the application uses React and Redux there are two main options:

  • ???? implements for each field an event handler that dispatches an action creator, and the reducer that will receive the action… All the redux stuff.
  • ✔️ Or we could use a library that does all this work for us.

Redux-Form is a great option to do that job to you. It keeps track of all common application form state such as:

  • The fields that are in the form;
  • The values of each field;
  • The focused field;
  • If the field values are valid;
  • The fields that the user have interacted with;
  • If the form is being submitted;
  • If is happening any asynchronous validation.

Back then Redux-Form didn't have an established alternative, but nowadays we have great options such as Formik and Final-Form, and both use React's component state.

When writing a Redux application, we should keep all the data that matters to the application in the in the application state as long as it makes sense. But the point is, reason about what make more sense for your application and pick your choice.
