IndustryState

Immutable state for your factories.

Requirements

This extension requires that the factory function returns a stateful object.

Usage

import { factory } from "industry"
import { functions } from "industry-functions"
import { instance } from "industry-instance"
import { standard_io } from "industry-standard-io"
import { state } from "industry-state"
 
class Test {
  init() {
    this.state({ a: 1 })
  }
 
  a({ state: { a } }) {
    return a
  }
}
 
let test = factory(Test)
  .set("functions", functions)
  .set("instance", instance)
  .set("state", state)
  .set("standard_io", standard_io)
 
test({ b: 2 })
test().state() // { a: 1, b: 2 }
test.a() // { value: 1 }
