Create a React app with Supabase Auth

About this guide

This development guide walks you through everything you need to do to build a high-quality React app integrated with Supabase Auth. Check out the tasks below to get started. To save time, you can also use our boilerplate, which gives you a complete React codebase with all of these tasks done for you. Okay, let's dive in!

Tasks

• Setup your React appGet the code

  Setup a React app using npx create-react-app and routing using React Router. There are many ways you can structure your app, but a common setup is to have an App component that defines top-level routes, with each route component imported from the /pages directory. The rest of your components should be located in your /components directory. You can then run your app locally with the npm run start command.

• Create a Supabase AuthProvider and useAuth hookGet the code

  Create an AuthProvider component that fetches the current user from Supabase, subscribes to changes, stores the user in state, and then makes all this data available to child components using Context.Provider. Make sure to update your App component so that AuthProvider wraps all your pages. You'll then create a useAuth hook that reads the user with useContext and returns its value. This will enable any component to call useAuthto get the current user and re-render when it changes.

• ‍Protect pages with a Supabase requireAuth HOCGet the code

  Create a requireAuth higher order component for pages that should only be viewable by authenticated users. It should call your useAuth hook internally to get the current user, show a loading indicator while waiting on the response, and then either render the page or redirect to /signin depending on whether the user is authenticated.

• Build your authentication UIGet the code

  Create an authentication UI using your component library of choice and Supabase functions. You'll want routes for user sign-up, sign-in, forgot password, and change password. Make sure you properly validate inputs and display any errors returned by Supabase. You may also want to use a library, such as React Hook Form, for managing form state.

• Link user to analytics sessionGet the code

  You can connect Google Analytics sessions to the current authenticated user with the User ID feature. This allows you to see what your users are doing across sessions and devices. You'll need to update your useAuth hook to set the user_id property whenever the user changes.

Get the code

You can get the code for this guide with our React and Supabase Auth Boilerplate. You'll get a complete React codebase with Supabase Auth integration, all the tasks listed above done for you, and a responsive multi-page template. It should save you about two weeks of development time.
