Create a Next.js app with Auth0 and Bulma

About this guide

This development guide walks you through everything you need to do to build a high-quality Next.js app integrated with Auth0 and Bulma. 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.

• Extend the Auth0 libraryGet the code

  Create a file that wraps the auth0-js library and abstracts away the storage and retrieval of the user's access token. Auth functions, such as auth0.signupAndAuthorize() and auth0.client.login(), should store the access token in memory or local storage after executing. Add a function called getCurrentUser() that fetches the current user by passing the stored access token to auth0.client.userInfo(). Our auth logic in subsequent tasks can call this function to get the current user.

• Create an Auth0 AuthProvider and useAuth hookGet the code

  Create an AuthProvider component that fetches the current user from Auth0, 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 an Auth0 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 an .is-loading element centered on the page.

• Build your authentication UIGet the code

  Create an authentication UI using Bulma elements and Auth0 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 Auth0. 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.

• Enable Auth0 email and password updatingGet the code

  To allow users to update their email and password you'll need to setup an API endpoint. Create a Next.js API route at /pages/api/auth-user.js that uses the auth0 library and calls Auth0.ManagementClient.updateUser() to change this info. Make sure that Auth0.ManagementClient is instantiated with the credentials for a "Machine to Machine" app, instead of your client-side app credentials. You can then create an updateUser function in the Auth0 wrapper you previously setup that makes a request to this endpoint.

• ‍Create an Auth0 callback pageGet the code

  In order to support social login via OAuth you'll need to setup an Auth0 callback page and specify it's path as the redirectUri value when calling auth0.popup.authorize(). This page should use the auth0-js library and call auth0.popup.callback() on load. This is what enables your app to get the authentication results after the OAuth flow has completed.

• Ensure Bulma link elements hook into Next.js routingGet the code

  Make all Bulma link elements hook into Next.js routing by wrapping them with the Link component from next/link.

• 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 BulmaGet the code

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

Get the code

You can get the code for this guide with our Next.js, Auth0, and Bulma Boilerplate. You'll get a complete Next.js codebase with Auth0 and Bulma 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.
