@rimbu/actor

This package offers state management tools to create stateful logic that can be easily integrated in any framework.

This package is still experimental, and therefore does not yet have complete documentation.

For complete documentation please visit the Rimbu Docs or the Rimbu API Docs.

Installation

Yarn/NPM

yarn add @rimbu/actor

or

npm i @rimbu/actor

Deno

For Deno, the following approach is recommended:

In the root folder of your project, create or edit a file called import_map.json with the following contents (where you should replace x.y.z with the desired version of Rimbu):

{
  "imports": {
    "@rimbu/": "https://deno.land/x/rimbu@x.y.z/"
  }
}

Note: The trailing slashes are important!

In this way you can use relative imports from Rimbu in your code, like so:

import { List } from '@rimbu/core/mod.ts';
import { HashMap } from '@rimbu/hashed/mod.ts';

Note that for sub-packages, due to conversion limitations it is needed to import the index.ts instead of mod.ts, like so:

import { HashMap } from '@rimbu/hashed/map/index.ts';

To run your script (let's assume the entry point is in src/main.ts):

deno run --import-map import_map.json src/main.ts

Usage

import { Actor, Obs } from '@rimbu/actor';

const obs = Obs.create({ count: 0, changes: 0 });

const actor = Actor.create(obs, {
  increase() {
    obs.patchState({ count: (v) => v + 1, changes: (v) => v + 1 }),
  }
  decrease() {
    obs.patchState({ count: (v) => v - 1, changes: (v) => v + 1 }),
  }
});

console.log(actor.state);
// => { count: 0, changes: 0 }
actor.increase()
actor.increase()
actor.decrease()
console.log(actor.state)
// => { count: 1, changes: 3 }
