A simple diary for offline tree houses.

baumhaus-tagebuch

We have a demo deployed on IPFS. It uses a websocket connection to our test server on topiq.es. This is a simple web-chat application which leverages replikativ for its state management.

chat42 consists of two parts, a client written with ClojureScript and om-next (react) that compiles into efficient Javascript, and a server written in Clojure that brokers communication between peers over a websocket. The server will be available for node.js soon and is only necessary to ensure a communication channel.

There is also a react native client.

It was initially created as a presentation for ClojureScript in our local JavaScript meetup.

Usage

You need to have Leiningen installed.

Client development

Just run figwheel and edit core.cljs as needed. If the replikativ parts are un clear, also have a look at the API walkthrough.

lein figwheel

This allows you to develop the client in an offline mode.

Server peer

If you want to persist and distribute the state, run the server with:

lein run

The server uses an in-memory backend to allow quick resets, if you want to persist the data on disk, use a filestore by commenting out the mem-store instead:

(<?? S #_(new-mem-store) (new-fs-store "/tmp/chat42"))

The web clients will automatically connect to this peer on localhost. You can now open two tabs and the two chat clients will communicate over the server and update instantly.

If you want to open the socket on a broader interface, change the uri string. This is necessary if you want to connect clients from the local network or the internet.
