Create a Next.js app with Supabase Auth and Bootstrap

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 Auth and Bootstrap. 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 Next.js appGet the code

  Create a Next.js app using npx create-next-app and then run your project locally with the npm run dev 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 Next.js 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. For the loading indicator you might try a Spinner component centered on the page.

• Build your authentication UIGet the code

  Create an authentication UI using Bootstrap components 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.

• Ensure Bootstrap link components hook into Next.js routingGet the code

  Make all Bootstrap link components hook into Next.js routing by wrapping them with the Link component from next/link and setting passHref to true.

• Create a persistent layoutGet the code

  Add any components that you'd like displayed across all pages (such asNavbar and Footer) to your Next.js 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.

• ‍Finish your app UI with BootstrapGet the code

  Build out the rest of your UI using Bootstrap components and composing them into high-level page sections, such as HeroSection and AccountSettings. Use SASS stylesheets for styling your components and overriding default component styles. You can scope each stylesheet to a single component using BEM syntax or CSS Modules.You should find our library of pre-built Bootstrap components to be helpful.

Get the code

You can get the code for this guide with our Next.js, Supabase Auth, and Bootstrap Boilerplate. You'll get a complete Next.js codebase with Supabase Auth and Bootstrap 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.
