k-ramel

State manager for your app components, the safe and easy way.

Why should you give it a try? 🤔

Because k-ramel:

• ⚡️ is fast
• 📸 is immutable
• 📦 is modular
• 💎 encourages to decouple UI and state management
• 💥 encourages to not have side effect into your business logic
• 👌 has a light bundle size footprint
• 🐛 works with redux-dev-tools

Getting started

This getting started helps you to understand how to do things like that!

const listeners = [
  // when the user clicked on "add a todo" button
  // we ask the API to add a new todo (the title is hardcoded for simplicity here)
  when('@@ui/ADD_TODO>CLICKED')((action, store, drivers) => {
    drivers.http('TODO').post(
      'https://todo-backend-modern-js.herokuapp.com/todos',
      {
        title: 'Yo! I am a new todo!',
      },
    )
  }),
  // when the API responds (not in error),
  // we add the new todo returned by the API in the store
  when('@@http/TODO>POST>ENDED')((action, store) => {
    store.todos.add(action.payload)
  }),
  // when a new todo is added to the store
  // we log a message :)
  when('@@krf/ADD>TODOS')(() => {
    console.log('A todo is added!')
  }),
]

Ecosystem

You can pick some modules based on your usage, or even write your own.
The modules that are supported by k-ramel are listed here.
We add modules when we need them but feel free to open PR if you want to add your own.

Modules can be :

• connectors, used to connect your business logic (and your data) to your UI. We only have a ReactJS connector at the moment.
• drivers, used to do some side effects (http, window, history, etc) or share some logic, besides your business logic.

How to use k-ramel

k-ramel is a data store that allows you to listen to event and then react to it. In a reaction you can access:

• the outside world via drivers, this is where you put your side effects, like HTTP calls
• your data, via store

Then if you connect an UI to k-ramel, via connectors, it can be refreshed each time the store is updated.

You can find documentation about each part of k-ramel there:

• store
• listeners
• reactions
• drivers
