API requests

Learn how to make requests to your Remix API in Makerkit

To make requests to the API functions in the api folder, we provide a custom hook useApiRequest, a wrapper around fetch.

It has the following functionality:

  1. Uses an internal state to keep track of the state of the request, like loading, error and success. This helps you write fetch requests the "hooks way"
  2. Automatically adds a Firebase AppCheck Token to the request headers if you enabled Firebase AppCheck
  3. Automatically adds a CSRF token to the request headers

Similarly to making Firestore Requests, it's a convention to create a custom hook for each request for readability/reusability reasons.

import useApiRequest from '~/core/hooks/use-api'; interface Body { idToken: string; } export function useCreateSession() { return useApiRequest<void, Body>('/api/session/sign-in'); }

The hook returns an array with:

  1. the callback to make the request
  2. the state object of the request
const [createSession, createSessionState] = useCreateSession();

The state object internally uses useApiRequest, and has the following interface:

{ success: boolean; loading: boolean; error: string; data: T | undefined; }

When success is true, the property data is inferred with its correct type.

You can use this hook in your components:

import { useCreateSession } from '~/core/hooks/use-create-session'; function Component() { const [createSession, createSessionState] = useCreateSession(); return ( <> { createSessionState.loading ? `Loading...` : null } { createSessionState.error ? `Error :(` : null } { createSessionState.success ? `Yay, success!` : null } <SignInForm onSignIn={(idToken) => createSession({ idToken })} /> </> ); }

Similarly, you can also use it to fetch data:

import { useCreateSession } from '~/core/hooks/use-create-session'; function Component() { const [fetchMembers, { loading, error, data }] = useFetchMembers(); // fetch data when the component mounts useEffect(() => { fetchMembers(); }, [fetchMembers]); if (loading) { return <div>Fetching members...</div>; } if (error) { return <div>{error}</div>; } return ( <div> { => <MemberItem member={member} />)} </div> ); }
