lmk v1.0.1

lmk

Simple cross-file/cross-class data manager.

npm i lmk or yarn add lmk

Import it:

const lmk = require('lmk')

import * as lmk from 'lmk'

How to use it

To set a value at a path:

lmk.set('my_data.my_key').to('my_value')

Our base object is now equal to:

{
  my_data: {
    my_key: 'my_value'
  }
}

To get a value at a path:

lmk.get('my_data.my_key') // => 'my_value'
lmk.get('my_data') // => {my_key: 'my_value'}
lmk.get('fake_key') // => undefined
lmk.get('fake_key', 'my_default_value') // => 'my_default_value'

To listen for when a value at a path isChanged:

lmk.when('my_data.my_key').isChanged(newValue => {
  console.log(newValue)
})

To end a subscription:

const unsubscribe = lmk.when(...).isChanged(...)
// later, when we don't want to hear about changes anymore
unsubscribe()

To remove a value:

lmk.remove('some_key') // deletes anything at 'some_key'
