Jbarzegar Component
A Fork of
What?
Declarative version of React.Component. Which also allows users to make "class methods"
Why?
Because sometimes you want a lifecycle, class methods or some state but don't want to create a new component. Also, this stuff is composable as heck.
Installation
npm install @jbarzegar/component
# or
yarn add @jbarzegar/component
And then import it:
// using es modules
import Component from "@jbarzegar/component";
// common.js
const Component = require("@jbarzegar/component");
// AMD
// I've forgotten but it should work.
Or use script tags and globals.
<script src="https://unpkg.com/@jbarzegar/component"></script>
And then grab it off the global like so:
const Component = ReactionsComponent;
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:
// import Component from '@jbarzegar/component'
const Component = ReactComponentComponent;
ReactDOM.render(
<div>
<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>
</div>,
DOM_NODE
);
Or maybe you need a little bit of state but an entire component seems a bit heavy:
// import Component from '@reactions/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
);
Orrr you want to write some functions
import Component from '@jbarzegar/Component'
<Component
initialState={{
count: 0
}}
handlers={{
increment: ({ setState, state }, ...params) =>
setState({ count: state.count + 1 }),
decrement: ({ state, setState }, ...params) =>
setState({ count: state.count - 1 })
}}
>
{({ handlers, state }) => (
<div>
<h1>{state.count}</h1>
<button onClick={handlers.decrement}>-</button>
<button onClick={handlers.increment}>+</button>
</div>
)}
</Component>
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 })
handlers({ state, setState, props, forceUpdate }, ...params)
Some notes on handlers
It must be an object
