Value

Simple value that can be hooked into React.

Source code is hosted on GitHub

yarn

yarn add @corets/value

npm

Seamless React integration is shipped in a separate package:

useValue

These packages provide extended functionality and are built on top of this library:

StoreListLocal Storage ValueLocal Storage StoreLocal Storage List

createValue()

Create a new observable value:

import { createValue } from "@corets/value"

const count = createValue(0)

Create a new observable value without the factory function:

import { Value } from "@corets/value"

const value = new Value(0)

Create a new observable value with a custom differ:

import { createValue } from "@corets/value"

const differ = (oldValue, newValue) => true
const count = createValue(0, { differ })

Value.get()

Get current value:

value.get()

Value.set()

Update current value:

value.set("new value")

Value.listen()

Listen to value changes:

const unsubscribe = value.listen((value) => console.log(value))

unsubscribe()

Invoke listener immediately:

value.listen((value) => console.log(value), { immediate: true })

Listen with a custom differ:

const differ = (oldValue, newValue) => true

value.listen((value) => console.log(value), { differ })

Value.use()

Convenience method for people used to React's useState syntax:

import { createValue } from "@corets/value"

const [value, setValue] = createValue(1).use()
