Insight 📝

Using passport as it is framework agnostic comparedto https://next-auth.js.org/. However, we must pin the version of passport to 0.5.3 as there is an issue with many cookie packages with the latest stable of 0.6.0 (see issue).

https://github.com/vvo/iron-session is used to manage cookies.

The implementation leverages two types of middleware:

• Built into Next.JS middleware via the file middleware.ts. This is used to render pages.
• Custom middleware built with https://www.npmjs.com/package/next-connect to handle API requests. Inspired by the work done in https://github.com/blockprotocol/blockprotocol/tree/main/site.
  This structure is future-proof as it allows the addition of new middleware easily. Learn more about the reasons for using a middleware-based architecture in this article.

For the ORM and database client, https://github.com/prisma/prisma is set up and used.
