flow-runtime-mobx

Adds mobx support to flow-runtime.

Why?

Because mobx observables don't pass standard checks like Array.isArray(observableArray) or observableMap instanceof Map.

Installation

npm install flow-runtime-mobx

or

yarn add flow-runtime-mobx

Usage

Before you use any observable objects you must register the types:

import t from 'flow-runtime';
import * as mobx from 'mobx';
import flowRuntimeMobx from 'flow-runtime-mobx';

flowRuntimeMobx(t, mobx); // only need to do this once.

You are now free to use ObservableArray and ObservableMap in place of their native equivalents thoughout your app:

import {observable, ObservableMap} from 'mobx';

type Thing = {
  numbers: number[];
  map: Map<string, string>;
};

const thing: Thing = observable({
  numbers: [1, 2, 3],
  map: new ObservableMap({foo: 'bar'})
});

console.log(thing);
