Watch

HoC component to see what's going on with your components

Install

The npm-way

npm i react-watch --save-dev

Example

Use it like any HoC:

import withWatching from 'react-watch';

const MyStatelessComponent = withWatching(({ a, b }) => <span>{a + b}</span>);

class MyClassComponent extends React.Component {
	render() {
		return (
			<p>
				<MyStatelessComponent />
				{this.props.children}
			</p>
		);
	}
}

MyClassComponent = withWatching(MyClassComponent);

Now looking at your console logs you should see something like

MyClassComponent will mount
MyClassComponent rendering
MyClassComponent rendered
MyStatelessComponent will mount
MyStatelessComponent rendering
MyStatelessComponent rendered
MyStatelessComponent did mount
MyClassComponent did mount

API

withWatching(Component [, loggerFunction = console.log.bind(console) [, forceEnable = false]])

• Component: a valid React component to watch. It will log all lifecycle methods.
• loggerFunction (optional): use a custom log function
• forceEnable (optional): enable the HoC also on non-development environments. If set to false, react-watch will be active only on development environment. See below.

Environment detection

react-watch will look at process.env.NODE_ENV and disable itself if it's not set to "development" environment.

On the client, use something like envify to replace process.env.NODE_ENV with its value at build time. If you use a smart minifier, you will completely get rid of react-watch on production.

If react-watch can't detect process.env.NODE_ENV, it will be disabled by default.

All this behavior can be overridden by setting forceEnable argument to true.
