Irving Forms

This package contains utilities, logic, and configuration for helping users create forms that submit to an external endpoint. Under the hood, this package uses react-hook-form to manage client-side form state and validation. This package consists of two peice you will need in order to set up connected form functionality:

• irving.config.js - a configuration preset for this package containing the sagas, reducers, and default state necessary to handle form state and data.
• useConnectedForm.js - a hook for managing form state, integrating with the react-hook-form API, and triggering form submissions.

Configuration

Configuration for submitting forms and managing their state in redux is a simple process. Import the irving config from the forms package, and add the imported config to the packages section of your project's config. Example:

import formsConfig from '@irvingjs/forms';

export default {
    packages: [
        formsConfig,
    ],
};

Integrating useConnectedForm

This hook will help you create a form that will submit to an external endpoint and report its status to Irving's internal, global redux data store.

The useConnectedForm hook expects two parameters when called:

• formEndpoint - a form endpoint in one of three possible formats:
  • A string (containing no forward slashes). This will submit your form to an endpoint nested unter a form endpoint path. Example: if your endpoint root is https://my-domain.com/api and you provide myForm as the first parameter to useConnectedForm, it'll submit the form to https://my-domain.com/api/form/myForm.
  • A path. This will submit your form to an endpoint at your api root. Example: if your endpoint root is https://my-domain.com/api and you provide lorem/ipsum/myForm as the first parameter to useConnectedForm, it'll submit the form to https://my-domain.com/api/lorem/ipsum/myForm.
  • A fully-qualified URL. This will submit your for to the URL provided, as-is. Example: if you provide https://another-endpoint.com/api as the first parameter to useConnectedForm, it'll submit the frm to https://another-endpoint.com/api.
• useFormOpts - options to pass to the underlying instance of react-hook-form's useForm hook. See the react-hook-form documentation for all available options.

useConnectedForm will return an object containing data you can use in any way you choose:

• onSubmit - a function you can supply to a form onSubmit event handler to validate (if configured) and submit your form to the provided endpoint.
• formApi - the react-hook-form api, returned directly from the underlying instance of the useForm hook. See the react-hook-form documentation for the full API.
• formState - global redux state for this form. This state contains the following fields:
  • submitting (bool) - whether or not the form is in the process of submitting.
  • submitted (bool) - if the form has been successfully submitted to your endpoint.
  • failed (bool) - if the form submission has failed
  • validation (object) - contains a key for each of your form fields. If you perform any form validation on the backend (once the form has been submitted), this is where validation messages should appear.
  • redirect (string) - location for the form to redirect users too upon successful submission.
