#Server-side API

TeamPlay provides a server-side API for setting up the backend and handling connections. This API is typically used in your server setup code.

#createBackend()

Creates a new TeamPlay backend instance.

import { createBackend } from 'teamplay/server'

const backend = createBackend()

#initConnection(backend, options)

Initializes the connection handler for WebSocket connections.

import { initConnection } from 'teamplay/server'

const { upgrade } = initConnection(backend, options)

#Parameters

• backend: The TeamPlay backend instance created with createBackend().
• options (optional): An object with the following properties:
  • fetchOnly (default: true): If true, server-side subscriptions are not reactive.

#Return Value

Returns an object with an upgrade function to be used with a Node.js HTTP server.

#Usage Example

import http from 'http'
import { createBackend, initConnection } from 'teamplay/server'

const server = http.createServer()
const backend = createBackend()
const { upgrade } = initConnection(backend)

server.on('upgrade', upgrade)

server.listen(3000, () => {
  console.log('Server started on port 3000')
})

#Additional Exports

TeamPlay's server module also re-exports some utilities:

• ShareDB: The underlying ShareDB library.
• mongo, mongoClient, createMongoIndex: MongoDB utilities.
• redis, redlock: Redis utilities.
• sqlite: SQLite utility.

These can be imported from teamplay/server if needed for advanced configurations.

#Notes

• The server-side API is designed to work with Node.js HTTP servers.
• For production use, it's recommended to use MongoDB by setting the MONGO_URL environment variable.
• When deploying to a cluster with multiple instances, set the REDIS_URL environment variable for proper scaling.
