room-server

Creates a room database that you can connect to over HTTP, socket.io, and osc!

You can test it out by running node server after installing the dependencies with npm install

installing

If you have systemd, you can generate and install a service file with npm run systemd

We also have a git post-receive hook which we setup like so:

# on remote machine
git clone --bare https://github.com/jedahan/room-server.git room-server.git
mkdir room-server
# on local machine
git remote add my-remote-machine ssh://my-remote-machine/home/room/room-server.git

After deploying the default branch, the post-receive hook checks it out and restarts the system service. neat.

example http

$ curl -d '{"fact": "#curl is an app at (20, 30)"}' -H "Content-Type: application/json" localhost:3000/assert
OK

$ curl -d '{"facts": ["$what is an app at ($x, $y)"]}' -H "Content-Type: application/json" localhost:3000/select
{"assertions":[{"what":{"id":"curl"},"x":20,"y":30}]}

example websocket

from examples/browser.js

const socket = io.connect(`http://localhost:3000`)

socket.on('solutions', solutions => {
  solutions.forEach(solution => {
    console.log(`what am i? a ${solution.what.str}`)
  })
})

socket.on('id', ({id}) => {
  console.log(`got id '${id}'`)
})

socket.emit('assert', ['i am a browser'])

setInterval(() => {
  socket.emit('select', ['i am a $what'])
}, 5000)
