rabbit-context

A framework base on React new Context API but it can avoid nesting hell.

Installation

yarn add rabbit-context or npm i rabbit-context

Usage (4 steps)

Step 1: Declare your Provider.

1import Context from 'rabbit-context'
2
3// Everything is similar to React.Component
4class ProfileProvider extends Context.Provider {
5  constructor(props) {
6    super(props)
7    this.state = {name: 'rabbit'}
8  }
9  updateName = name => {
10    this.setState({name})
11  }
12}

Step 2: New a Context.

1const context = new Context(ProfileProvider) // or: const context = new Context({ProfileProvider})

Step 3: Inject a Component, then return an injected Component.

1const $InjectedComponent = context.inject(AnyComponent)

Step 4: Set context.Provider and use it.

1function App(props) {
2  return (
3    <div>
4      <h1>App</h1>
5      <$InjectedComponent {...props} />
6    </div>
7  )
8}
9document.render(
10  <context.Provider>
11    <App msg="hello" />
12  </context.Provider>,
13document.getElementById('root'))

That's all usages of rabbit-context, enjoy!

API

Context.Provider

Context.Provider is extends React.Component. So, you can do anything as same as you do in React.Component. But DO NOT write any lifecycle and render in your Context.Provider.

new Context(Providers: Context.Provider|object, smartTransform: boolean = true)

You can construct Context.Provider in two ways.

1. new Context(ProfileProvider)
2. new Context({ProfileProvider, ContactProvider})

smartTransform will auto transform ProfileProvider and ContactProvider to profile and contact as {profile, contact} in second way when passing compositedProps to injected Components, compositedProps is composited with values from Provider and the props from parent Component, and the second one has higher priority.

context.inject(Component: React.Component): React.Component

Return a wrapped Component that you can receive values as props from Providers.
