feat(chatapps): implement generic platform adapter template (RFC #218)#304
Conversation
Add a reference implementation template in chatapps/template/ that provides a starting point for creating new ChatApps platform adapters. The template includes: - config.go: Configuration struct with validation - adapter.go: Main adapter with ChatAdapter interface implementation - errors.go: Platform-specific error definitions - README.md: Documentation and usage guide Developers can copy this template and implement the TODO sections to quickly add support for new messaging platforms like Discord, Telegram, etc. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add Phase 1 & 2 of the platform adapter template: - chatapps/base/template.go: Core interfaces - EventParser[T]: Generic event parsing - PlatformFormatter: Message formatting - PlatformSender: Message sending - SignatureValidator, error types - chatapps/base/platform_adapter.go: Generic template - PlatformAdapter[T]: Orchestrates common workflow - HandleWebhook: Signature → Parse → Convert → Handler - SendMessage, DeleteMessage, UpdateMessage implementations - Implements ChatAdapter and MessageOperations interfaces - chatapps/base/signature.go: Add SkipVerify to NoOpVerifier Verification: - go build ./chatapps/... ✓ - go vet ./chatapps/... ✓ - go test ./chatapps/base/... ✓ Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Demonstrate using the new generic PlatformAdapter[T] template with a simplified Slack adapter implementation: - SlackSignatureVerifier: Platform-specific signature verification - SlackEventParser: Event parsing with base.EventParser[Event] - SlackFormatter: Message formatting with base.PlatformFormatter - SlackSender: Message sending with base.PlatformSender - TemplateAdapter: Simplified adapter using the template This shows the boilerplate reduction achievable with the template: - ~250 lines vs ~800+ lines in full adapter.go - Clear separation of concerns - Reusable components Verification: - go build ./chatapps/slack/... ✓ - go vet ./chatapps/slack/... ✓ - go test ./chatapps/slack/... ✓ Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Demonstrate new platform integration using the generic template: - chatapps/discord/adapter.go: Complete adapter using PlatformAdapter[T] - DiscordSignatureVerifier: Ed25519 signature verification stub - DiscordEventParser: Interaction parsing - DiscordFormatter: Message formatting - DiscordSender: REST API integration - Adapter: Template-based adapter struct This shows how quickly a new platform can be added: - ~200 lines vs 800+ lines for full-featured adapters - Clear separation of platform-specific components - Reusable generic template infrastructure The template enables 60%+ code reduction for new platform integrations.
