Related to this SO question: https://stackoverflow.com/questions/66366486/how-to-add-authentication-in-nuxt-js-content-docs-theme

This is an example on how to make an authenticated @nuxt/docs-theme documentation project thanks to Auth0. The project is an SPA to disallow a non-JS access to the documentation.

Configuration

The requirements are to:

• setup the whole Auth0 configuration
  • go to Applications sidebar section
  • create a native app (application type), then go to the Settings tab
  • fill in the domain, let's say dope-asdasd.auth0.com (can be basically whatever before auth0)
  • get your client ID key
  • for allowed callback URLs, Allowed Logout URLs, Allowed Web Origins, Allowed Origins (CORS) you can basically set http://localhost:3000, https://documentation.dope-website.com
• go to Connections > Database sidebar section and enable Username-Password-Authentication
  • Requires Username > true
  • Disable Sign Ups > true
  • Enable your app in the Applications tab
• Go to Users & Roles > Users sidebar section
  • Create a user there and validate it's email
• go back to Applications > your-app-name, Connections tab and double check that Username-Password-Authentication is enabled
• follow this configuration section: https://auth.nuxtjs.org/providers/auth0/#pkce-grant-flow
• fill in the AUTH0_DOMAIN and AUTH0_CLIENT_ID env variables (used in nuxt.config.js) into Netlify or any static provider (.env file for local debugging)

Then, you should have access to it locally and on any static hosting solution. Working great so far and cannot be accessed by disabling the JS, good solution for a secure private documentation.

Screenshots

Here is how it looks after the local server is running (npm run dev).

You cannot access the misc > test doc page, you will be redirected to the Login one automatically until you do have the JWT Auth0 token. The latter is given by entering the credentials set in the Auth0 Users configuration page.

Once you have everything set up, you will be able to access the secure Test page.

PS: once authenticated, I'm not sure how to clear it. Auth0 seems to have some kind of verification even if you clear your cookies. But if you try it in another browser or in a private window, you will see that you'll need auth so it's working great on this point.
