if you want to do partial refactoring and need no connection between the old and the new, use the node and koa2 framework to build a front-end service, use node to manage your static resources, and route

has recently been working on the React refactoring jQuery project, which I would like to share with you.

1. Use < div id= "rebuild_id" > < / div > to stay where you need refactoring in the old project.
2. Completely use the React project to do that part of the refactoring. At this point, you need to know what parameters need to be passed to the react refactored part from the old part, and what the React section needs to return to the old code. The
parameter and the returned content are handled in index.js . When developing, you can write a mock data.
similar:

export function startup(containerId, inport, outport) {
    ReactDOM.render(<App {...inport} callback={data => outport(data)} />, document.getElementById(containerId));
}

5, packaged, packaged React project, which can be introduced in the old project. It depends on how the old project was introduced.
6. After it is introduced in the old project, just startup (.) is fine.
