Redux middleware for action side effects withcallbag

You may not need redux-saga/redux-observable. When you use redux-callbag, you will find that this's what you want.

• 🙀 Minisize
• 🙀 Scalable
• 🙀 Easy to understand

npm install --save  redux-callbag

• async-redux-callbag

This API is used to create middleware

This API is used to select action

If action-type is undefined, it is equivalent to select to initialize the action, as you can pass multiple action-types

This API is used to insert promise flow

This API is used to dispatch action when callbags chain is successed

This API is used to dispatch action when callbags chain is failed

You can install the latest version of babel7(@babel/cli), and use @babel/plugin-proposal-pipeline-operator.
