Applications

Bassline is multi-purpose. Drop in or modify the systems below to enhance your projects.

Database
// Connect to your database
const db = createDbAdapter({
  type: 'postgres',
  connection: process.env.DATABASE_URL
})

// Query and write via paths
const users = await app.get({ path: '/db/users' })
await app.put({ path: '/db/users/123' }, {
  name: 'Alice', email: 'alice@example.com'
})
P2P Connection
// Connect to a remote peer
await remote.put({ path: '/peer1' }, {
  url: 'ws://localhost:9111'
})

// Proxy requests through the connection
const data = await remote.get({
  path: '/peer1/proxy/cells/counter'
})
await remote.put({
  path: '/peer1/proxy/cells/counter/value'
}, 42)
Cells
// Create a cell with lattice semantics
await kit.put({ path: '/cells/score' }, {
  lattice: 'maxNumber'
})

// Concurrent writes merge automatically
await kit.put({ path: '/cells/score/value' }, 50)
await kit.put({ path: '/cells/score/value' }, 30)
// → still 50, max wins

await kit.get({ path: '/cells/score/value' })
Propagators
// Create reactive cells
await kit.put({ path: '/cells/celsius' }, { lattice: 'lww' })
await kit.put({ path: '/cells/fahrenheit' }, { lattice: 'lww' })

// Wire them together
await kit.put({ path: '/propagators/c-to-f' }, {
  inputs: ['/cells/celsius'],
  output: '/cells/fahrenheit',
  fn: '/fn/c-to-f'
})
// Set celsius → fahrenheit updates automatically
