Spectrum

Spectrum is Photon's unified messaging SDK. Write your handler logic once against a single app.messages stream and deliver it across every platform — iMessage, WhatsApp Business, your terminal, or a custom platform you build yourself.

The current SDK is spectrum-ts (TypeScript). Spectrum is multi-platform by design and multi-language is on the roadmap — additional language SDKs (e.g. Python, Go, Swift) will join the family. The architecture, primitives, and patterns described in this skill are intended to be language-neutral; code samples in the topic files are currently TypeScript and are flagged where the API surface is language-specific (imports, syntax, runtime types).
