React Integration: How to connect react components with rails backend? - ruby-on-rails

Question

Apologies if there is a simple answer to this, but I'm very new to react.
I'm building an application in react and I'm trying to integrate two basic forms (register/login) with a rails backend. I don't really need to authenticate the user at this point, I just need it to remember the user and create a session.
Is there an easy way to do this that avoids using something like Devise? If somebody could point me in the right direction, it would be greatly appreciated.
As I mentioned the forms will be very basic. Something like this:
<form>
<label for='email'>Email Address:</label>
<input type="text" name="email" />
<label for='password'>Password:</label>
<input type="text" name="email" />
<button> Login</button>
</form>
and
<form>
<label for='email'>First Name:</label>
<input type="text" name="first-name" />
<label for='password'>Last Name:</label>
<input type="text" name="last-name" />
<label for='email'>Email Address:</label>
<input type="text" name="email" />
<label for='password'>Password:</label>
<input type="text" name="password" />
<label for='password'>Confirm Password:</label>
<input type="text" name="password" />
<button> Register</button>
</form>
Thanks in advance.

Answer 1

You need to create Rest Api on your Rails backend. Once you have your API endpoints you can make calls from react on those endpoints using fetch or axios whichever u like.

Answer 2

First, your rails backend need to be a rest API, if already is, you need to make the request of your react app, I recommend you to use Axios
