Table of Contents

Motivation & Spec

Since tokens are used everywhere make achieve better QR code experience, we should allow users to customize how to generate/store/update token records.

Basic APIs that a token storage should support:

  • async init(), optional, should be called before creating any instance, open a database connection, creating a embed database on file system
  • async create(token, status = created), create a new token record, persist in data store
  • async exist?(token, did), check for token existense
  • async read(token), read a token from database,
  • async update(token, updates), update token record
  • async delete(token), remove a token record
  • async gc(), optional, run garbage collection on the token storage

Plan to support:

  • token-storage-mongo
  • token-storage-psql
  • token-storage-nedb
  • token-storage-memory
