Writing Taubyte Functions (Go SDK)

When to use

• Authoring a new Go handler (HTTP / PubSub / P2P)
• Reading or fixing existing function source
• Wiring a function to a database, storage, messaging channel, or library
• Calling another library's exported function from inside a function
• Calling external HTTP services from inside a function
• Producing PubSub messages from an HTTP function
• Surfacing a WebSocket URL to a browser
• Using IPFS-backed files

Mental model

A Taubyte serverless function is a TinyGo-compiled WebAssembly module. The SDK (github.com/taubyte/go-sdk) is a Go wrapper over host functions the Taubyte VM exports. You write Go, compile to WASM (via the taubyte/go-wasi Docker recipe — see verifying-taubyte-functions), and the cloud invokes your exported function for each event.
