sketch-magnetic-poetry

This is a multiplayer magnetic poetry web toy, running at magnetic-poetry.use-fireproof.com.

Users can drag and drop word tiles in collaboration with others in the same room. You can choose to save poems to the attached Fireproof database. Click the 🔥 link to see your data in the database.

Thanks to Matt Webb for creating the original app this is based on.

What you'll find here

This app is based on Next.js and PartyKit.

To share state, PartyKit keeps a Poem object in party-side storage. When a client connects, it receives the entire object in a websocket message called sync. When a client makes a turn, the new tile is added to the mosaic, and broadcast to all others in the room as an update message.

Saved poems are archived to the database and the raw data can be accessed by clicking the 🔥 link.

To see this code:

server (party-side): src/partykit/server.ts
client: src/app/Room.ts

You can see the database connection in src/app/Room.ts: connect.partykit(database, process.env.NEXT_PUBLIC_PARTYKIT_HOST!)

And see how to configure PartyKit for Fireproof in partykit.json:

{
  "name": "magnetic",
  "main": "src/partykit/server.ts",
  "parties": {
    "fireproof": "node_modules/@fireproof/partykit/src/server.ts"
  }
}

To run this locally

Clone the repo, then (assuming you have Node.js installed):

npm install
cp .env.example .env  # tells the app where to find the partyserver
npx partykit dev  # runs the partyserver
npm run dev       # runs the app

Then go to localhost:3000 to use the app (check out multiplayer by opening multiple browser windows).

The state of the game is kept in room storage. There's a debug endpoint so you can see the current state (you'll need to refresh the page to see changes). Go to 127.0.0.1:1999/party/announcer -- check out the the partyserver code for how this works.
