Docs

1. bindActionCreators(object: actionCreators)(ctx) => object: actions

Param actionCreators is a object contain action creators, like:

bindActionCreators({
  getIp: () => {},
  getUserName: () => {},
})

it will return a function, and then pass param ctx to this function. like:

const ctx = {
  req: {},
  res: {}
}

bindActionCreators({
  getIp: () => {},
  getUserName: () => {},
})(ctx)

it will return a object contains {getIp, getUserName}, now you can use getIp directly.

2. connect(function: bindActionCreators(actionCreators))(beConnected) => function: wrappedActionCreator

An action is written like (..args) => (ctx, getAction) => {...}, so if you want to use getAction method, you must connect it with other actions you need. like:

const getName = (...args) => (ctx, getAction) => {
  const {getParentName} = getAction()
  return getParentName(...args) + args[1]
}
// ... after do bindActionCreators(...)(ctx), you run getName() will
// cause an Error 'getParentName is not a function'

const connectedGetName = connect(
  bindActionCreators({
    getParentName
  })
)(getName)
// this will be ok
