zeusdeux/jwt-example: Playing with user registration, login/logout, auth, etc using JWTs, serverless functions & faunadb as the data store.

This is an example codebase that implements user registration and supports authorization using JWTs using serverless functions and the wonderful FaunaDB.

I wrote this to teach myself how JWTs work and also implement user registration and login/logout, etc flows serverlessly.

• sign up as new user (or re-sign up as a deleted user which is transparent to the user)
• login and get JWT with 1 hour expiry (multiple logged in sessions supported)
• access protected route with only with a valid token
• logout (kills all logged in sessions and invalidates all tokens for the user)
• delete user
• In-situ encrypted JWT signing/validation key pair to overcome AWS Lambda having a hard limit of 4kb on env vars when JSON-stringified

• todos in code
• switch to argon2 from bcrypt

  Waiting on vercel/nft#53 to switch to argon2

• api/* holds the lambdas that map to each supported route
• models/* holds the models for the entities in the system (User & Token) and some helpers
• errors/* holds the custom error tooling for the codebase
• utils/* hold code structure and type level utilties

I wanted to play with a different way of approaching authoring the code in this repository. Instead of messing with try/catch-es and lots of error handling madness, I have instead opted to push those to the edges as you can see in models/User.helpers.ts and instead wrap those values in Maybes and/or Eithers. These values are then accessed in a declarative manner using match. Their usage, imho, has greatly simplified the code as you can see in the api/*.ts. It's not everyone's ☕and I get that.

More info can be found in files with the same names under they utils/ directory.
