tiny-store

Tiny immutable store for any value

Install

npm install tiny-store

Use

let store = require('tiny-store')

// create a fruit
let data = { fruit: 'apple' }
apple = store(data)

// try & change FAIL
console.log(apple()) // { fruit: 'apple' }
apple().fruit = 'pear'
console.log(apple()) // { fruit: 'apple' }
data.fruit = 'orange'
console.log(apple()) // { fruit: 'apple' }

// update
let grape = apple({ fruit: 'grape' })
console.log(grape()) // { fruit: 'grape' }
console.log(apple()) // { fruit: 'apple' }

Implementation Notes

This uses a recursive Object.freeze under the hood. It's turned off in production (process.env.NODE_ENV === 'production').

If you use strict at top of your JS, the script will throw at runtime if you try and make changes like this: apple().fruit = "pear".
