Simple Redux Form Checker

This is a simple module that provides a function for redux form validation, along with the necessary action and reducer. If you are looking for a very simple way to validate a Redux form before submitting it to the backend, this may be helpful. In case you are in search of a more sofisticated solution, this is not for you, sorry.

How to use this module

You may download this repo and add it to your project, or you may install it using npm install, it is up to you. Either way you choose, once you have it, you will need to add formErrors to your reducers. In the component where you will have the form you would like to validate, you will need to import checkFormErrors, which is an action creator, and validateForm, which is a function that checks if the inputs of your form and returns a promise. You may provide the function to submit your form if it is all right, and an errors parameters to catch and checkFormErrors if it is not all right.

Example:

validateForm(formInputs, minLength) .then(()=> {/*Whatever you want to do if the form passess */} ) /* Of course, you can chain other then's */ .catch((errors) => this.props.checkFormErrors(errors));

Besides checkFormErrors and validateForm, you need to pass formErrors to your mapStateToProps function.
