From Finnish kaiku /ˈkɑi̯ku/, meaning echo.

A lightweight JSX-based UI framework with a freely mutable, boilerplate-free global state management.

Try it out!

Getting started

Kaiku is packaged to be easily used in both browser and as a module, no build tools required:

<script type="module">
  import { h, render, createState } from 'https://unpkg.com/kaiku'

  const state = createState({ greeting: 'Hello world' })
  const App = () => h('span', null, state.greeting)

  render(h(App), document.body)
</script>

Or, just install the package using your favorite package manager:

# With NPM
npm i -s kaiku

# With yarn
yarn add kaiku

Example

A simple ticker component with global state management.

import { render, createState } from 'kaiku'

const state = createState({ ticks: 0 })

const Ticker = () => (
  <div>
    <div>
      There have been <b>{state.ticks} ticks</b> since last update.
    </div>
    <button onClick={() => { state.ticks = 0 }}>Reset</button>
  </div>
)

setInterval(() => state.ticks++, 1000)

render(<Ticker />, document.body)
