mobx-init-on-demand v0.0.7

mobx-init-on-demand

npm, github

Initialize large mobx objects on read, instead of on creation. For extremely large objects, this defers the performance cost of wrapping objects in mobx containers until they are actually needed.

Usage

yarn add mobx-init-on-demand

import { observableOnDemand } from 'mobx-init-on-demand';

const myObservable = observableOnDemand({
    ... // your large object here
})

// use the observable as normal
autorun(() => {
  console.log(myObservable.some.deep.nested.prop)
})
