memory-decay

Background

In many applications it seems like a useful capability to have datafields of an object automatically deleted after some time.

E.g. authentication codes, which are valid for a limited time.

With this package you initialize the Object first, then whenever you want to have automatic deletion, call the obj.letForget("key") function.

Usage

Requirements

• ESM importability

Installation

Current git version:

npm install git+https://github.com/JhonnyJason/memory-decay-output.git

Npm Registry:

npm install memory-decay

Current Functionality

• Set a global default decay time.
• Prepare an object such that it's datafields may be forgotten -> adds letForget function
• Specify a specific datafield to be forgotten in the specified time letForget(key, timeMS) - timeMS is optional
• If you call letForget again it will postpone the deletion to the new time.

setDefaultDecayMS = (decayTimeMS) ->
makeForgetable  = (object, decayTimeMS) -> object
# here decayTimeMS is optional - defaultDecayMS will be take if decayTimeMS is not specified
# the same object as provided is returned
# the object now has a new function attached
object.letForget = (key, decayTimeMSs) ->
# also here decayTimeMS is optional - either the Object specified or the global default is taken if decayTimeMS is not specified

import { makeForgetable } from "memory-decay"

## default default is 30000ms
volatileIdeaMemory = makeForgetable({})

volatileIdeaMemory.task1 = "think about task 2"
volatileIdeaMemory.letForget("task1") ## is forgotten in 30000ms

volatileIdeaMemory.task2 = "plan task 3"
volatileIdeaMemory.letForget("task1", 1000) ## is forgotten in 1000ms


longtermMemory = {}
makeForgetable(longtermMemory, 30000000000)
longtermMemory.secret = "super secret secret"
longtermMemory.letForget("secret") ## is forgotten in 347 days

Further steps

• maybe make a proxy out of it so that the "letForget" is always implicitely triggered when set
• figure out what to do next^^

All sorts of inputs are welcome, thanks!
