callbag-connect-react

A utility for connecting a React component with Callbag sources. Comparable to ReactRedux, but for Callbags instead of Redux!

npm install callbag-connect-react

usage

import connect from 'callbag-connect-react

@connect(
  { // Objects are assumed to contain sourcess
    propName: source1,
    ...
  },
  [ // Arrays are assumed to contain signals
    [source2, callback],
    ...
  ]
})
class MyComponent extends React {
  ...
}

Now;

• Whenever source1 emits data, that will be sent to the propName prop in MyComponent.
• Whenever source2 emits, callback will be invoked with (componentInstance, emission).

Sources

An object where the keys are prop names and values are sources. When a source emits, the corresponding prop will be populated.

Signals

An array of tuples, each tuple is an array with a source and a callback. Whenever the source emits, the callback will be called with the component instance and the emitted data.

Use signals when you want your component to do something other than render when a source emits.
