reactive-vanillajs v1.1.1

Reactive Vanilla JS

This is a framework-agnostic library for implementing reactive, Svelte store-like data stores, that can be used anywhere to store global-state, business-logic, caching API requests, etc... Anything you need to store, can be stored.

Usage

• In a Javascript/Typescript file, export a reactiveStore(value), where value is the initial store value. It can be a default or named export.
• In another file, import your store.
• Use store.subscribe(callback), where callback is a function that takes the current value. Make sure to store the returned callback in a variable (const unsubscribe = store.subscribe(callback)) so you can call it later to remove the subscription and prevent memory leaks

Setting and updating value

• Use store.set(value) to set a value directly
• Use store.update(callback) to return a new value based on the current one. Callback is a function that takes the current value and returns a value.

Additional features

• In store.subscribe, in addition the the callback, you may pass an option with below properties:

{
    // If false, will not run the callback until the value changes. Default value: true
    runOnSubscription?: boolean
}

• Typescript supported! The library is written in TS anyways so types are included for those who use it

Missing features

• React hooks: This library is framework-agnostic, so while I'd love to implement it and it's easy to do so, I'm leaving it out
