Create a React app with Supabase DB and Material UI

About this guide

This development guide walks you through everything you need to do to build a high-quality React app integrated with Supabase DB and Material UI. 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 Supabase query hooksGet the code

  Create React hooks that wrap your Supabase queries, such as useUser, useItem, and useItemsByUser. These hooks should fetch data and return a query status of "success", "loading", or "error". The React Query library makes it especially easy to setup these hooks and have components re-render when data changes.

• Create Supabase tables and policiesGet the code

  Create the database tables that your app requires. For a simple SaaS app you could start with tables for users, customers and items. Your customers and items tables would generally have a user_id column that references users.id. You can create these tables right in your Supabase dashboard, but we recommend writing a create table SQL snippet for each table, allowing you to easily recreate them in the future. Lastly, you'll want to enable Row Level Security for your tables and secure read/write access with policies.

• Setup a trigger to create user in database on signupGet the code

  When a user signs up with Supabase Auth you'll want to automatically insert their data to the users table so that you can easily query on it. This can be accomplished with a trigger. Setup a trigger that inserts a new row into the users table when a user signs up. You'll also want to create a trigger that updates that data when a user's auth email changes. This ensures that your database is always in sync with user data in Supabase Auth.

• Build a data-driven UIGet the code

  Create a data-driven UI using Material UI components that reads/writes data to Supabase. The specifics will depend on the type of app you're building, but we generally recommend having a useItemsByOwner hook that fetches "items" in Supabase that are owned by the current user. You can then create a component for displaying that data in a simple list or table if more columns are needed. Finally, you'll want create a flow for creating and updating items utilizing Material UI modal and form components.

• Ensure Material UI link components hook into React RouterGet the code

  Make all Material UI link components hook into React Router by using the component prop and setting the value to Link from react-router-dom.

• Create a persistent layoutGet the code

  Add any components that you'd like displayed across all pages (such asNavbar and Footer) to your App component. If you need multiple persistent layouts you can instead have each page define its own layout. In that case, create multiple layout components (such as LandingPageLayout and AdminLayout) and wrap the contents of each page.

• Add a Material UI ThemeProviderGet the code

  Add the Material UI ThemeProvider component so that you customize theme values. If your entire app uses the same theme (as opposed to different nested themes), then the best way to do this is update your App component so that ThemeProviderwraps all your pages.

• Add dark mode supportGet the code

  To support dark mode you'll need to define a light and dark Material UI theme object, read the user's preference from local storage on mount, fall back to their browser default using prefers-color-scheme, and pass the correct theme object to ThemeProvider. You'll also want to create a useDarkMode React hook that any component can call to get/toggle the user's preference. Be sure to check out our example Material UI components with dark mode toggle.

• ‍Finish your app UI with Material UIGet the code

  Build out the rest of your UI using Material UI components and composing them into high-level page sections, such as HeroSection and AccountSettings. Use Material UI's CSS-in-JS solution for styling your components and overriding default component styles. You should find our library of pre-built Material UI components to be helpful.

Get the code

You can get the code for this guide with our React, Supabase DB, and Material UI Boilerplate. You'll get a complete React codebase with Supabase DB and Material UI 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.
