react-state-store v0.0.1

react-state-store

Give you the ability to decide when and what states to execute in setState

Installation

npm install react-state-store --save

Why

Sometimes I have setState in different functions for seperating logic. Then when I try to use them in combination, I hope they can execute setState only one time so that it won't re-render too much.

this.setState({attribute1: name1})
callback(
	this.setState({attribute2: name2})
	(() => {
		this.setState({attribute3: name3})
	})(this);
)

But I hope execute setState only one time

Usage

1 . Require react-state-store after installation

        })
