### Practical Functional Reactive Programming

Reflex is a fully-deterministic, higher-order Functional Reactive Programming (FRP) interface and an engine that efficiently implements that interface.

[Reflex-DOM](https://github.com/reflex-frp/reflex-dom) is a framework built on Reflex that facilitates the development of web pages, including highly-interactive single-page apps.

A summary of Reflex functions is available in the [quick reference](Quickref.md).

### Hacking

From the root of a [Reflex
Platform](https://github.com/reflex-frp/reflex-platform) checkout, run
`./scripts/hack-on haskell-overlays/reflex-packages/dep/reflex`. This
will check out the reflex source code into the
`haskell-overlays/reflex-packages/dep/reflex` directory. You can then
point that checkout at your fork, make changes, etc. Use the
`./try-reflex` or `./scripts/work-on` scripts to start a shell in
which you can test your changes.
