purescript-concur-react

Concur UI Lib is a brand new client side Web UI framework that explores an entirely new paradigm. It does not follow FRP (think Reflex or Reactive Banana), or Elm architecture, but aims to combine the best parts of both. This repo contains the Concur implementation for Purescript, using the React backend.

Work in progress tutorials are published in the Concur Documentation site

API documentation is published on Pursuit.

1. Concur for Haskell - The original version of Concur written in Haskell.
2. Concur for Javascript - An official but experimental port to Javascript.

You can quickly get a production setup going (using Parcel) by cloning the Purescript Concur Starter.

Else you can also install purescript-concur manually using bower -

bower install purescript-concur-react

git clone https://github.com/ajnsit/purescript-concur.git
cd purescript-concur
npm install
# Build examples
npm run ps
# Check examples
open html/index.html

Concur supports using external React components. For example, there is an ongoing effort to create concur bindings for SemanticUI-React. Look at the Sources, and the Demo.
