Registry toolkit

Want to keep track of and work with all fish of a specific type? Meet the RegistryFish pattern.

scalable, reuseable, composable, and maintainable

One thing that has come up quite a few times is the need to track all fish of a certain kind in someplace. You may have a fish representing a specific entity on your shop-floor. There are going to be many instances of this fish, one for each entity. Now, what if you wanted to show a list of all these entities somewhere?

The registry pattern will lead you to a data model that is scalable, reuseable, composable, and maintainable.

Read more about it in the blog post.

📦 Installation

Registry toolkit is available as an npm package.

npm install @actyx-contrib/registry

📖 Example / Micro tutorials

This library is made to reduce the code you write.

Using Callbacks:

import { observeRegistry } from '@actyx-contrib/registry'
import { ChatRoomRegistryFish, ChatFish } from "./fish/chatFish"
import { Pond } from '@actyx/pond'

Pond.default().then(pond => {
  observeRegistry(pond, MachineFish.registry, Object.keys, MachineFish.of, states => console.log(states))

using RxJS:

import { observeRegistry$ } from '@actyx-contrib/registry'
import { ChatRoomRegistryFish, ChatFish } from "./fish/chatFish"
import { RxPond } from '@actyx-contrib/rx-pond'

RxPond.default().then(rxPond => {
  observeRegistry$(pond, MachineFish.registry, Object.keys, MachineFish.of)
    .subscribe(states => console.log(states))
