		[react-derivable](https://github.com/jevakallio/react-derivable) is where it's at.
		The fantastic project [react-derivable](https://github.com/andreypopp/react-derivable) lets you use
		derivables in your render method, providing seamless interop with component-local state and props.

		### With Redux

		DerivableJS can be used as a kind-of replacement for reselect, by just doing something like this:

		```javascript
		const $Store = atom(null);

		myReduxStore.subscribe(() => $Store.set(myReduxStore.getState()));
		```

		and then you derive all your derived state from $Store, rather than

		### Examples (very wip)
		### Examples

		The best example of writing good code with Derivables right now is the [talk demo](https://github.com/ds300/derivables-talk-demo), which is presented as a 'diff tutorial' and should be read from the initial commit.
		Coming soon.

		The next best is the [routing walkthrough](https://github.com/ds300/derivablejs/tree/master/examples/routing/README.md)

		I've also implemented a solution to @staltz's [flux challenge](https://github.com/staltz/flux-challenge/tree/master/submissions/ds300).

		There is a proper gitbook tutorial on the way!

		### Browser
		Either with browserify/webpack/common-js-bundler-du-jour or build as umd bundle with `npm run build -- --umd`
		Either with browserify/webpack/common-js-bundler-du-jour, or clone the repo, run `npm install && npm run build`, then grab the UMD bundle from `dist/derivable.umd[.min].js` (source maps are also available).

		### Equality Woes
		JavaScript is entirely whack when it comes to equality. People do [crazy jazz](https://github.com/ramda/ramda/blob/v0.16.0/src/internal/_equals.js) trying to figure out if some stuff is the same as some other stuff.

		If the data you're threading through DerivableJS needs its own notion of equality, make sure it has a sensible `.equals` method and everything will be fine.

		If you're using a data library with some custom non-standard mechanism for doing equality checks (e.g. mori), then you'll need to re-initialize DerivableJS with a custom equality function.
