Rift UI

Rift is a swift-ui inspired framework for the web.

This is just a concept

Performance has not been considered for this project, it's just for fun!

Installation

npm i rift-ui --save or yarn add rift-ui

Usage

import {Root, View, Text} from 'rift-ui'

const App = View(
  Text('Welcome to my app!', 'h1').fontSize('20px').color('red'),
  Text('It rocks...'),
  Button('Click Me').onClick(() => console.log('wow'))
)

Root(document.getElementById('root), App)

Components

import {
  Component, // Base component class for extending new HTML element types
  Root,
  View,
  Text,
  Button,
  Img,
  ForEach,
  If,
  Stack,
  HStack,
  VStack
}

Styling

Styling can be chained onto components like so:

  Text('My Text')
    .color('red')
    .borderRadius('200px')
    .height('100px')

State

Functional components are injected with state like so:

  const MyComponent = (state = initialState, setState) => {
    return Text(state.text).onClick(() => {
      setState({
        text: 'wow!'
      })
    })
  }

  const App = View(
    MyComponent
  )

Props

  const MyComponent = (...props) => {
    return Text(props.text)
  }

  const App = View(
    MyComponent(props here...)
  )

Props & State

  const MyComponent = (...props) => (state = initialState, setState) => {
    // use state here
    return Text(props.text)
  }

  const App = View(
    MyComponent(props here...)
  )

Events

Current only the onClick event is supported:

  Text('My Text')
    .onClick(myFunction)

Attributes

There is a special .attr method for adding attributes to an element:

  Text('My Text')
    .attr('data-thing', true)

Method Components

Rift UI currently supports ForEach and If components, used like so:

  const App = View(
    ForEach(array, (item) => Text(Item)),
    If(thingIsTrue, Text('It is true!'))
  )
