koa-jwt-auth

@salsita/koa-jwt-auth

Configures authentication middleware.

Important options:

• key - secure key for hashing payload (if persistent key not provided, new key is generated with each server start - logging out all users)
• version - should be increased with every change in createSession function, so users using old structure are logged out
• createSession - function returning data which identifies user (usually user id)
• getUserForSession - function which checks if user exists/session is valid (data returned from createSession are supplied) and result is put into ctx.state.user
