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. 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 app
Setup a React app usingnpx create-react-app
and routing using React Router. There are many ways you can structure your app, but a common setup is to have anApp
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 thenpm run start
command.Create Supabase query hooks
Create React hooks that wrap your Supabase queries, such asuseUser
,useItem
, anduseItemsByUser
. 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 policies
Create the database tables that your app requires. For a simple SaaS app you could start with tables forusers
,customers
anditems
. Yourcustomers
anditems
tables would generally have auser_id
column that referencesusers.id
. You can create these tables right in your Supabase dashboard, but we recommend writing acreate 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 signup
When a user signs up with Supabase Auth you'll want to automatically insert their data to theusers
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 theusers
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 UI
Create a data-driven UI using your component library of choice that reads/writes data to Supabase. The specifics will depend on the type of app you're building, but we generally recommend having auseItemsByOwner
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 modal and form components.
Get the code
You can get the code for this guide with our React and Supabase DB Boilerplate. You'll get a complete React codebase with Supabase DB 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.
