Lemni

Lemni allows us to implement React components and aplications in a functional and reactive way, making it much more natural to deal with the asynchronicity of interfaces, as well as isolating side effects away from the actual implementation.

Installation

You may install Lemni through npm or Yarn:

npm i @lemni/core

# or

yarn add @lemni/core

Hello World

Lemni creates conventional React components, fully compatible with the entire React ecosystem, including React Native.

import ReactDOM from 'react-dom'
import { lemni } from 'lemni'

const HelloWorld = lemni(
  sources => ({
    view: (viewArgs) =>
      <div>
        <p>Hello World</p>
      </div>
  })
)

ReactDOM.render(
  <HelloWorld />,
  document.getElementById('app')
)

Basic Component

import { lemni } from 'lemni'
import xs from 'xstream'

const Incrementer = lemni(sources => {
  const onIncrement = xs.Stream.create()

  return {
    initialState: {
      count: 0,
    },

    stateReducer: onIncrement.mapTo(
      state => ({
        count: state.count + 1,
      })
    ),

    view: ({ state, emitter }) => (
      <p>Count: {state.count}</p>
      <button onClick={emmiter(onIncrement).emit}>
        Increment
      </button>
    )
  }
})
