API documentation React

getContainerSetHooks

Generates a set of app specific container hooks

// my-app-hooks.ts
import React, { useContext } from "react"
import { getContainerSetHooks } from "iti-react"
import { getProviders, PizzaAppContainer } from "./_root.store"

export const MyRootCont = React.createContext(<PizzaAppContainer>{})

let mega = getContainerSetHooks(getProviders, MyRootCont)
export const useContainerSet = mega.useContainerSet

// PizzaData.tsx
import { useContainerSet } from "./my-app-hooks"
export const PizzaData = () => {
  const containerSet = useContainerSet((containers) => [containers.kitchen])
  console.log(containerSet)
  return 123
}

useContainer

export const PizzaData = () => {
  const [kitchenContainer, err] = useContainer().kitchen
  if (!kitchenContainer || err) {
    return <>Kitchen is loading</>
  }

  return <>{kitchenContainer.oven.pizzasInOven}</>
}

useContainerSet

Get multiple containers and autosubscribes to change.

export const PizzaData = () => {
  const containerSet = useContainerSet((containers) => [
    containers.kitchen,
    containers.auth,
  ])
  if (!containerSet) {
    return <>Kitchen is loading</>
  }

  return <>{containerSet.kitchen.oven.pizzasInOven}</>
}

generateEnsureContainerSet

You can create a simpler API for a portion of your applicatoin to avoid dealing with async in every component. There are some helpfull Context helpers at your service. Also you can use classic props drilling to avoid dealing with async flow in every component

import React, { useContext } from "react"
import { useContainerSet } from "../containers/_container.hooks"
import { generateEnsureContainerSet } from "iti-react"

const x = generateEnsureContainerSet(() =>
  useContainerSet(["kitchen", "pizzaContainer", "auth"]),
)
export const EnsureNewKitchenContainer = x.EnsureWrapper
export const useNewKitchenContext = x.contextHook

export const PizzaApp = () => {
  return (
    <div>
      Pizza App:
      <EnsureNewKitchenContainer
        fallback={<>Pizza App is still loading please wait</>}
      >
        <NewPizzaPlaceControls />
      </EnsureNewKitchenContainer>
    </div>
  )
}
export const PizzaData = () => {
  const { kitchen, pizzaContainer } = useNewKitchenContext()

  return (
    <div>
      <div>Name: {kitchen.kitchen.kitchenName}</div>
      <div>Tables: {pizzaContainer.diningTables.tables}</div>
    </div>
  )
}
