React Component ... Component

What?

Declarative version of React.Component.

Why?

Because sometimes you want a lifecycle or some state but don't want to create a new component. Also, this stuff is composable as heck.

Installation

npm install react-component-component
# or
yarn add react-component-component

And then import it:
// using es modules
import Component from "react-component-component";

// common.js
const Component = require("react-component-component");

// AMD
// I've forgotten but it should work.

Or use script tags and globals.
<script src="https://unpkg.com/react-component-component"></script>

And then grab it off the global like so:
const Component = ReactComponentComponent;

How?

Let's say you want some async data but don't want to make a whole new component just for the lifecycles to get it:
```render-babel // import Component from 'react-component-component' const Component = ReactComponentComponent;
ReactDOM.render(
<h2>Let's get some gists!</h2>
<Component
  initialState={{ gists: null }}
  didMount={({ setState }) => {
    fetch("https://api.github.com/gists")
      .then(res => res.json())
      .then(gists => setState({ gists }));
  }}
>
  {({ state }) =>
    state.gists ? (
      <ul>
        {state.gists.map(gist => (
          <li key={gist.id}>{gist.description}</li>
        ))}
      </ul>
    ) : (
      <div>Loading...</div>
    )
  }
</Component>
, DOMNODE );
Or maybe you need a little bit of state but an entire component
seems a bit heavy:

```render-babel
// import Component from 'react-component-component'
const Component = ReactComponentComponent;

ReactDOM.render(
  <Component initialState={{ count: 0 }}>
    {({ setState, state }) => (
      <div>
        <h2>Every app needs a counter!</h2>
        <button
          onClick={() =>
            setState(state => ({ count: state.count - 1 }))
          }
        >
          -
        </button>
        <span> {state.count} </span>
        <button
          onClick={() =>
            setState(state => ({ count: state.count + 1 }))
          }
        >
          +
        </button>
      </div>
    )}
  </Component>,
  DOM_NODE
);

Props

You know all of these already:
  • didMount({ state, setState, props, forceUpdate })
  • shouldUpdate({ state, props, nextProps, nextState })
  • didUpdate({ state, setState, props, forceUpdate, prevProps, prevState })
  • willUnmount({ state, props })
  • children({ state, setState, props, forceUpdate })
  • render({ state, setState, props, forceUpdate })
