@rimbu/actor

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

For complete documentation please visit the Rimbu Docs.

Installation

Yarn/NPM

yarn add @rimbu/actor

or

npm i @rimbu/actor

Deno

Create a file called rimbu.ts and add the following:

export * from 'https://deno.land/x/rimbu/actor/mod.ts';

Or using a pinned version (x.y.z):

export * from 'https://deno.land/x/rimbu/actor@x.y.z/mod.ts';

Then import what you need from rimbu.ts:

import { Actor } from './rimbu.ts';

Because Rimbu uses complex types, it's recommended to use the --no-check flag (your editor should already have checked your code) and to specify a tsconfig.json file with the settings described below.

Running your script then becomes:

deno run --no-check --config tsconfig.json <your-script>.ts

Recommended tsconfig.json settings

Rimbu uses advanced and recursive typing, potentially making the TS compiler quite slow. It is recommended to set the following values in the tsconfig.json file of your project:

{
  "compilerOptions": {
    "skipLibCheck": true,
    "noStrictGenericChecks": true
  }
}

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 }
