Description

As noted in a comment on #97, developers who want to write a Store implementation either need to:

  1. extend their Store from express-session's store.js, which typically means requiring express-session as a dependency
  2. implement their own version of the functionality in store.js, session.js, and cookie.js (or copy the files from express-session)

This is because express-session requires the following methods on the Store in order to work:

  • regenerate()
  • load()
  • createSession()

These are available in store.js, but createSession itself requires both session.js and cookie.js.

The documentation should be updated to provide guidance on these facts.

Research direction
Update the README to explain that developers implementing a custom Store must either extend from store.js (which requires express session as a dependency) or replicate methods from store.js, session.js, and cookie.js. Refer to the comment on issue #97 for context. The documentation should specify that three methods are required: regenerate(), load(), and createSession().
