Introduction

@byu-oit-sdk/session is the parent module of @byu-oit-sdk/session-fastify, @byu-oit-sdk/session-express, and @byu-oit-sdk/session-dynamo. While this package technically can be used on its own, those other packages are more purpose-built and well-documented than this one.

This package exports the following:

• A Session class that represents a users session data that can be stored and retrieved.
• An abstract SessionStore class
• A MemorySessionStore that implements SessionStore and acts as a basic, in-memory session store that should not be used in production but functions just fine while testing on a local machine.
  • @byu-oit-sdk/session-dynamo also implements SessionStore and is recommended for production use.

Configuring the MemorySessionStore

Though the MemorySessionStore shouldn't be used in production, its use is recommended for testing locally. It doesn't need any configuration to use, but there are some environment variables associated with the node-cache that it uses which can be overridden to change the default behavior.

Env Var Name	Purpose	Default Value
NODE_CACHE_TTL	This is the time-to-live as a number in seconds for every generated cache element. Set to 0 for unlimited lifespan.	120
NODE_CACHE_CHECK_PERIOD	The amount of seconds to wait before performing automatic deletion checks.	110

There are also some options that can be passed in the constructor:

Constructor Option Name	Type	Default	Purpose
maxLockTime	number	10	Optional. The max amount of seconds that a row can be locked before it is allowed to be forcibly unlocked.

See the documentation of the repositories linked above for usage and configuration details.
