About this guide
This development guide walks you through everything you need to do to build a high-quality Next.js app integrated with Supabase DB and Tailwind. 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
Create a Next.js app using Setup your Next.js app
npx create-next-app
and then run your project locally with thenpm run dev
command.Create React hooks that wrap your Supabase queries, such as Create Supabase query hooks
useUser
,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 the database tables that your app requires. For a simple SaaS app you could start with tables for Create Supabase tables and policies
users
,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.When a user signs up with Supabase Auth you'll want to automatically insert their data to the Setup a trigger to create user in database on signup
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 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.Create a data-driven UI using Tailwind elements that reads/writes data to Supabase. The specifics will depend on the type of app you're building, but we generally recommend having a Build a data-driven UI
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 Tailwind modal and form components.Install Tailwind and add a Install and configure Tailwind
tailwind.config.js
file by following the Tailwind guide for Next.js.Make all Tailwind link elements hook into Next.js routing by wrapping them with the Ensure Tailwind link components hook into Next.js routing
Link
component fromnext/link
.Add any components that you'd like displayed across all pages (such as Create a persistent layout
Navbar
andFooter
) to your Next.jsApp
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 asLandingPageLayout
andAdminLayout
) and wrap the contents of each page.Build out the rest of your UI using Tailwind elements and composing them into high-level page sections, such as Finish your app UI with Tailwind
HeroSection
andAccountSettings
. Use theming and dynamic classes for styling your components and overriding default element styles.
Get the code
You can get the code for this guide with our Next.js, Supabase DB, and Tailwind Boilerplate. You'll get a complete Next.js codebase with Supabase DB and Tailwind 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.
