From 4aeb60eec3b36f996b2403440c1216532626e9fa Mon Sep 17 00:00:00 2001 From: "claude[bot]" <41898282+claude[bot]@users.noreply.github.com> Date: Fri, 10 Apr 2026 21:29:54 +0000 Subject: [PATCH 01/17] feat: initialize monorepo structure and development infrastructure Sets up the complete project bootstrap per issue #1: Monorepo: - Bun workspaces with packages: core, storage/mongodb, channels, server, trust - Shared tsconfig.base.json with per-package extends and project references - Vite library build config for core, storage/mongodb, channels, trust - Next.js setup for the server package Quality tooling: - ESLint v9 flat config with @typescript-eslint + prettier integration - Prettier with consistent formatting rules - lint-staged config in package.json for pre-commit hooks - husky prepare script (run `bun install` to initialize hooks) CI/CD: - GitHub Actions workflow: lint, typecheck, test on push/PR Dev environment: - Docker Compose with MongoDB 7.0 - .env.example with documented variables - Seed script at scripts/seed.ts for sample channels, routes, threads Co-authored-by: Gustavo Gondim --- .env.example | 51 ++++++++++ .github/workflows/ci.yml | 41 ++++++++ .gitignore | 32 ++++++ .prettierignore | 6 ++ .prettierrc | 9 ++ docker-compose.yml | 25 +++++ eslint.config.mjs | 38 ++++++++ package.json | 45 +++++++++ packages/channels/package.json | 29 ++++++ packages/channels/src/index.test.ts | 8 ++ packages/channels/src/index.ts | 5 + packages/channels/src/types.ts | 8 ++ packages/channels/tsconfig.json | 12 +++ packages/channels/vite.config.ts | 18 ++++ packages/core/package.json | 26 +++++ packages/core/src/index.test.ts | 8 ++ packages/core/src/index.ts | 5 + packages/core/src/types.ts | 68 +++++++++++++ packages/core/tsconfig.json | 9 ++ packages/core/vite.config.ts | 18 ++++ packages/server/next.config.ts | 7 ++ packages/server/package.json | 23 +++++ packages/server/src/app/layout.tsx | 14 +++ packages/server/src/app/page.tsx | 8 ++ packages/server/tsconfig.json | 19 ++++ packages/storage/mongodb/package.json | 33 +++++++ packages/storage/mongodb/src/adapter.ts | 30 ++++++ packages/storage/mongodb/src/index.test.ts | 8 ++ packages/storage/mongodb/src/index.ts | 4 + packages/storage/mongodb/tsconfig.json | 12 +++ packages/storage/mongodb/vite.config.ts | 18 ++++ packages/trust/package.json | 29 ++++++ packages/trust/src/index.test.ts | 8 ++ packages/trust/src/index.ts | 5 + packages/trust/src/types.ts | 21 ++++ packages/trust/tsconfig.json | 12 +++ packages/trust/vite.config.ts | 18 ++++ scripts/seed.ts | 108 +++++++++++++++++++++ tsconfig.base.json | 19 ++++ tsconfig.json | 10 ++ 40 files changed, 867 insertions(+) create mode 100644 .env.example create mode 100644 .github/workflows/ci.yml create mode 100644 .gitignore create mode 100644 .prettierignore create mode 100644 .prettierrc create mode 100644 docker-compose.yml create mode 100644 eslint.config.mjs create mode 100644 package.json create mode 100644 packages/channels/package.json create mode 100644 packages/channels/src/index.test.ts create mode 100644 packages/channels/src/index.ts create mode 100644 packages/channels/src/types.ts create mode 100644 packages/channels/tsconfig.json create mode 100644 packages/channels/vite.config.ts create mode 100644 packages/core/package.json create mode 100644 packages/core/src/index.test.ts create mode 100644 packages/core/src/index.ts create mode 100644 packages/core/src/types.ts create mode 100644 packages/core/tsconfig.json create mode 100644 packages/core/vite.config.ts create mode 100644 packages/server/next.config.ts create mode 100644 packages/server/package.json create mode 100644 packages/server/src/app/layout.tsx create mode 100644 packages/server/src/app/page.tsx create mode 100644 packages/server/tsconfig.json create mode 100644 packages/storage/mongodb/package.json create mode 100644 packages/storage/mongodb/src/adapter.ts create mode 100644 packages/storage/mongodb/src/index.test.ts create mode 100644 packages/storage/mongodb/src/index.ts create mode 100644 packages/storage/mongodb/tsconfig.json create mode 100644 packages/storage/mongodb/vite.config.ts create mode 100644 packages/trust/package.json create mode 100644 packages/trust/src/index.test.ts create mode 100644 packages/trust/src/index.ts create mode 100644 packages/trust/src/types.ts create mode 100644 packages/trust/tsconfig.json create mode 100644 packages/trust/vite.config.ts create mode 100644 scripts/seed.ts create mode 100644 tsconfig.base.json create mode 100644 tsconfig.json diff --git a/.env.example b/.env.example new file mode 100644 index 0000000..fc501dc --- /dev/null +++ b/.env.example @@ -0,0 +1,51 @@ +# ============================================================================= +# OpenThreads — Environment Variables +# Copy this file to .env and fill in your values. +# ============================================================================= + +# Server +PORT=3000 +NODE_ENV=development + +# MongoDB +# When using Docker Compose: mongodb://openthreads:openthreads@localhost:27017/openthreads +MONGODB_URI=mongodb://openthreads:openthreads@localhost:27017/openthreads + +# Security +# IMPORTANT: Change this in production!

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the full @openthreads/channels-slack package implementing the ChannelAdapter interface for Slack using @slack/bolt. Packages added: - packages/core — ChannelAdapter interface, A2H types, envelope types - packages/channels/slack — SlackAdapter class Features implemented: - Inbound: message events, app_mention events, /openthreads slash command - Outbound: text (mrkdwn), Block Kit blocks/buttons/select menus - Thread support: native Slack thread_ts ↔ OpenThreads threadId (1:1 map) - A2H AUTHORIZE → Approve/Deny Block Kit buttons (method 1) - A2H COLLECT with options → static_select menu (method 1) - A2H COLLECT free-text → thread reply capture (method 2) - A2H INFORM → plain text message - Capabilities: { threads, buttons, selectMenus, dms, fileUpload: true, replyMessages: false } Tests: - Unit tests for Block Kit builders (blocks.test.ts) - Unit tests for normalize utilities (normalize.test.ts) - Integration tests for SlackAdapter with mock App/WebClient (SlackAdapter.test.ts) - Shared adapter conformance suite (conformance.test.ts) Co-authored-by: claude[bot] --- package.json | 14 + packages/channels/slack/package.json | 24 + packages/channels/slack/src/SlackAdapter.ts | 593 +++++++++++++++++ .../slack/src/__tests__/SlackAdapter.test.ts | 620 ++++++++++++++++++ .../slack/src/__tests__/blocks.test.ts | 186 ++++++ .../slack/src/__tests__/conformance.test.ts | 242 +++++++ .../slack/src/__tests__/normalize.test.ts | 77 +++ packages/channels/slack/src/index.ts | 2 + packages/channels/slack/src/utils/blocks.ts | 162 +++++ .../channels/slack/src/utils/normalize.ts | 43 ++ packages/channels/slack/tsconfig.json | 11 + packages/core/package.json | 17 + packages/core/src/index.ts | 21 + packages/core/src/types.ts | 219 +++++++ packages/core/tsconfig.json | 8 + tsconfig.base.json | 16 + 16 files changed, 2255 insertions(+) create mode 100644 package.json create mode 100644 packages/channels/slack/package.json create mode 100644 packages/channels/slack/src/SlackAdapter.ts create mode 100644 packages/channels/slack/src/__tests__/SlackAdapter.test.ts create mode 100644 packages/channels/slack/src/__tests__/blocks.test.ts create mode 100644 packages/channels/slack/src/__tests__/conformance.test.ts create mode 100644 packages/channels/slack/src/__tests__/normalize.test.ts create mode 100644 packages/channels/slack/src/index.ts create mode 100644 packages/channels/slack/src/utils/blocks.ts create mode 100644 packages/channels/slack/src/utils/normalize.ts create mode 100644 packages/channels/slack/tsconfig.json create mode 100644 packages/core/package.json create mode 100644 packages/core/src/index.ts create mode 100644 packages/core/src/types.ts create mode 100644 packages/core/tsconfig.json create mode 100644 tsconfig.base.json diff --git a/package.json b/package.json new file mode 100644 index 0000000..aa8d1aa --- /dev/null +++ b/package.json @@ -0,0 +1,14 @@ +{ + "name": "openthreads", + "version": "0.0.1", + "private": true, + "workspaces": [ + "packages/core", + "packages/channels/slack" + ], + "scripts": { + "build": "bun run --filter '*' build", + "test": "bun run --filter '*' test", + "typecheck": "bun run --filter '*' typecheck" + } +} diff --git a/packages/channels/slack/package.json b/packages/channels/slack/package.json new file mode 100644 index 0000000..f68d2d3 --- /dev/null +++ b/packages/channels/slack/package.json @@ -0,0 +1,24 @@ +{ + "name": "@openthreads/channels-slack", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "./src/index.ts", + "exports": { + ".": "./src/index.ts" + }, + "scripts": { + "build": "tsc", + "test": "bun test", + "typecheck": "tsc --noEmit" + }, + "dependencies": { + "@openthreads/core": "workspace:*", + "@slack/bolt": "^3.21.1", + "@slack/web-api": "^7.3.4" + }, + "devDependencies": { + "@types/node": "^20.14.0", + "typescript": "^5.4.5" + } +} diff --git a/packages/channels/slack/src/SlackAdapter.ts b/packages/channels/slack/src/SlackAdapter.ts new file mode 100644 index 0000000..2489a62 --- /dev/null +++ b/packages/channels/slack/src/SlackAdapter.ts @@ -0,0 +1,593 @@ +/** + * Slack channel adapter for OpenThreads. + * + * Implements the full ChannelAdapter interface using the Slack Bolt framework. + * + * A2H delivery methods used: + * Method 1 (inline) — AUTHORIZE → Approve/Deny buttons + * — COLLECT with options → static_select menu + * Method 2 (thread capture) — COLLECT free-text → awaits thread reply + */ + +import { App } from '@slack/bolt';

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds packages/channels/discord — a full ChannelAdapter implementation for Discord using discord.js: Inbound: - message create, @mentions (parseMessage) - slash commands (parseSlashCommand + REST registration) Outbound: - plain text messages - styled Discord embeds (INFORM / AUTHORIZE / COLLECT / ESCALATE) - message components: approve/deny buttons (AUTHORIZE), select menus (COLLECT with closed options) Threads: - getThread / createThread supporting both TextChannel threads and ForumChannel posts (1:1 mapping with OpenThreads thread IDs) - ensureThreadActive helper to unarchive threads before sending A2H (method 1 + method 2): - buildA2HComponents maps A2H intents to Discord action rows - awaitResponse captures button/select interactions and thread replies - Timeout configurable via interactionTimeoutSeconds Capabilities: { threads, buttons, selectMenus, dms, fileUpload: true; replyMessages: false } Tests: - Unit tests for message/command parsing, component builders, embeds - Conformance tests verifying ChannelAdapter interface contract Co-authored-by: claude[bot] --- packages/channels/discord/package.json | 31 ++ .../discord/src/__tests__/adapter.test.ts | 316 ++++++++++++ .../discord/src/__tests__/conformance.test.ts | 124 +++++ packages/channels/discord/src/adapter.ts | 477 ++++++++++++++++++ .../channels/discord/src/inbound/commands.ts | 50 ++ .../channels/discord/src/inbound/index.ts | 2 + .../channels/discord/src/inbound/messages.ts | 44 ++ packages/channels/discord/src/index.ts | 34 ++ .../discord/src/outbound/components.ts | 148 ++++++ .../channels/discord/src/outbound/embeds.ts | 99 ++++ .../channels/discord/src/outbound/index.ts | 17 + .../channels/discord/src/outbound/text.ts | 55 ++ .../channels/discord/src/threads/index.ts | 113 +++++ packages/channels/discord/src/types.ts | 166 ++++++ packages/channels/discord/tsconfig.json | 19 + 15 files changed, 1695 insertions(+) create mode 100644 packages/channels/discord/package.json create mode 100644 packages/channels/discord/src/__tests__/adapter.test.ts create mode 100644 packages/channels/discord/src/__tests__/conformance.test.ts create mode 100644 packages/channels/discord/src/adapter.ts create mode 100644 packages/channels/discord/src/inbound/commands.ts create mode 100644 packages/channels/discord/src/inbound/index.ts create mode 100644 packages/channels/discord/src/inbound/messages.ts create mode 100644 packages/channels/discord/src/index.ts create mode 100644 packages/channels/discord/src/outbound/components.ts create mode 100644 packages/channels/discord/src/outbound/embeds.ts create mode 100644 packages/channels/discord/src/outbound/index.ts create mode 100644 packages/channels/discord/src/outbound/text.ts create mode 100644 packages/channels/discord/src/threads/index.ts create mode 100644 packages/channels/discord/src/types.ts create mode 100644 packages/channels/discord/tsconfig.json diff --git a/packages/channels/discord/package.json b/packages/channels/discord/package.json new file mode 100644 index 0000000..a02d5a7 --- /dev/null +++ b/packages/channels/discord/package.json @@ -0,0 +1,31 @@ +{ + "name": "@openthreads/channel-discord", + "version": "0.1.0", + "description": "Discord channel adapter for OpenThreads", + "type": "module", + "main": "./dist/index.js", + "module": "./dist/index.js", + "types": "./dist/index.d.ts", + "exports": { + ".": { + "import": "./dist/index.js", + "types": "./dist/index.d.ts" + } + }, + "scripts": { + "build": "tsc --project tsconfig.json", + "test": "bun test", + "test:integration": "bun test --grep integration", + "typecheck": "tsc --noEmit" + }, + "dependencies": { + "discord.js": "^14.16.3" + }, + "devDependencies": { + "@types/bun": "latest", + "typescript": "^5.7.2" + }, + "peerDependencies": { + "@openthreads/core": "workspace:*" + } +} diff --git a/packages/channels/discord/src/__tests__/adapter.test.ts b/packages/channels/discord/src/__tests__/adapter.test.ts new file mode 100644 index 0000000..b5f3a89 --- /dev/null +++ b/packages/channels/discord/src/__tests__/adapter.test.ts @@ -0,0 +1,316 @@ +/** + * Unit tests for the DiscordAdapter. + * + * These tests use mock Discord.js objects and do NOT require a real Discord + * bot token.

Key components: - types/index.ts: full data model (ChatSDKMessage, A2HMessage, ChannelAdapter, ReplyEngineConfig, and all supporting types) - reply-engine/normalizer.ts: normalize single object → 1-item array - reply-engine/classifier.ts: duck-typing classification (intent field = A2H) - reply-engine/method-selector.ts: decision tree for methods 1–4 with capture hierarchy for method 2 - reply-engine/response-collector.ts: TimeoutError, withTimeout(), and ResponseRegistry for pending form submissions (methods 3 & 4) - reply-engine/index.ts: ReplyEngine class orchestrating all of the above Unit tests cover: classification, method selection across all intent/capability combinations, normalizer, mixed arrays, method 4 batching, trust layer, timeout handling, escalation handler, and ResponseRegistry.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the full ChannelAdapter interface for WhatsApp using the Baileys library (WhatsApp Web protocol). Key features: - SessionManager: QR-code auth, multi-file auth-state persistence, automatic reconnection with exponential backoff, clean shutdown - Inbound: text, image, video, audio, document, sticker, button/list responses; virtual thread IDs via quoted-reply chains - Outbound: text, buttons (max 3), list messages, image/video/audio/ document media - A2H method 1: AUTHORIZE with ≤3 options → WhatsApp interactive buttons - A2H method 3: AUTHORIZE >3 options / COLLECT / complex intents → external form link - A2H method 2: quoted-reply capture for free-text responses (pending capture map with configurable timeout) - Capabilities: { threads: false, buttons: true, selectMenus: false, replyMessages: true, dms: true, fileUpload: true } - Conformance test suite covering capabilities, inbound/outbound, A2H flows, and lifecycle Co-authored-by: claude[bot] --- packages/channels/whatsapp/package.json | 31 + .../channels/whatsapp/src/SessionManager.ts | 228 +++++++ .../channels/whatsapp/src/WhatsAppAdapter.ts | 574 ++++++++++++++++++ .../src/__tests__/WhatsAppAdapter.test.ts | 519 ++++++++++++++++ packages/channels/whatsapp/src/index.ts | 59 ++ packages/channels/whatsapp/src/types.ts | 112 ++++ packages/channels/whatsapp/tsconfig.json | 13 + 7 files changed, 1536 insertions(+) create mode 100644 packages/channels/whatsapp/package.json create mode 100644 packages/channels/whatsapp/src/SessionManager.ts create mode 100644 packages/channels/whatsapp/src/WhatsAppAdapter.ts create mode 100644 packages/channels/whatsapp/src/__tests__/WhatsAppAdapter.test.ts create mode 100644 packages/channels/whatsapp/src/index.ts create mode 100644 packages/channels/whatsapp/src/types.ts create mode 100644 packages/channels/whatsapp/tsconfig.json diff --git a/packages/channels/whatsapp/package.json b/packages/channels/whatsapp/package.json new file mode 100644 index 0000000..02e5101 --- /dev/null +++ b/packages/channels/whatsapp/package.json @@ -0,0 +1,31 @@ +{ + "name": "@openthreads/channel-whatsapp", + "version": "0.1.0", + "private": true, + "type": "module", + "main": "./src/index.ts", + "exports": { + ".": "./src/index.ts" + }, + "scripts": { + "build": "tsc --project tsconfig.json", + "dev": "tsc --project tsconfig.json --watch", + "test": "bun test", + "typecheck": "tsc --noEmit" + }, + "dependencies": { + "@openthreads/core": "workspace:*", + "@whiskeysockets/baileys": "^6.7.18", + "@hapi/boom": "^10.0.1", + "pino": "^8.21.0", + "qrcode": "^1.5.4", + "qrcode-terminal": "^0.12.0", + "node-cache": "^5.1.2" + }, + "devDependencies": { + "@types/node": "^20.12.0", + "@types/qrcode": "^1.5.5", + "@types/qrcode-terminal": "^0.12.2", + "typescript": "^5.4.0" + } +} diff --git a/packages/channels/whatsapp/src/SessionManager.ts b/packages/channels/whatsapp/src/SessionManager.ts new file mode 100644 index 0000000..2a23d94 --- /dev/null +++ b/packages/channels/whatsapp/src/SessionManager.ts @@ -0,0 +1,228 @@ +import { + makeWASocket, + DisconnectReason, + useMultiFileAuthState, + fetchLatestBaileysVersion, + type WASocket, + type ConnectionState, + type AuthenticationState, +} from "@whiskeysockets/baileys";

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the full management dashboard UI for the OpenThreads server. ## Dashboard pages (/dashboard/*) - Overview: live stats (channel/route/thread counts) - Channels: list + add wizard (platform → credentials → test → save), edit/delete, masked API key with eye/copy toggle - Routes: ReactFlow visual flow (channel → route → recipient nodes), drag-to-create edges, criteria drawer, priority list, test route matching - Threads: searchable + filterable table, click-to-detail - Thread Detail: chronological turn timeline, A2H intent rendering, raw envelope collapsible - Settings: global TTL/trust-layer config + per-channel overrides ## New API endpoints - POST /api/routes/test — simulate inbound criteria → matching route IDs - GET /api/settings — read global settings from MongoDB - PUT /api/settings — update global settings ## Updated - GET /api/threads — channelId now optional; added search query param - lib/db.ts — listThreads(), AppSettings/ChannelOverride types, getSettings(), updateSettings() - Root page redirects to /dashboard - Root layout wraps with AntdRegistry for Next.js SSR CSS handling - lib/api-client.ts — new typed API client for dashboard pages fixes #13 Co-authored-by: Gustavo Gondim --- packages/server/next.config.ts | 2 +- packages/server/package.json | 4 + .../server/src/app/api/routes/test/route.ts | 33 ++ packages/server/src/app/api/settings/route.ts | 48 ++ packages/server/src/app/api/threads/route.ts | 18 +- .../src/app/dashboard/channels/page.tsx | 541 ++++++++++++++++++ packages/server/src/app/dashboard/layout.tsx | 109 ++++ packages/server/src/app/dashboard/page.tsx | 65 +++ .../app/dashboard/routes/RouteFlowCanvas.tsx | 336 +++++++++++ .../server/src/app/dashboard/routes/page.tsx | 520 +++++++++++++++++ .../src/app/dashboard/settings/page.tsx | 338 +++++++++++ .../app/dashboard/threads/[threadId]/page.tsx | 336 +++++++++++ .../server/src/app/dashboard/threads/page.tsx | 173 ++++++ packages/server/src/app/layout.tsx | 11 +- packages/server/src/app/page.tsx | 9 +- packages/server/src/lib/api-client.ts | 166 ++++++ packages/server/src/lib/db.ts | 68 +++ 17 files changed, 2755 insertions(+), 22 deletions(-) create mode 100644 packages/server/src/app/api/routes/test/route.ts create mode 100644 packages/server/src/app/api/settings/route.ts create mode 100644 packages/server/src/app/dashboard/channels/page.tsx create mode 100644 packages/server/src/app/dashboard/layout.tsx create mode 100644 packages/server/src/app/dashboard/page.tsx create mode 100644 packages/server/src/app/dashboard/routes/RouteFlowCanvas.tsx create mode 100644 packages/server/src/app/dashboard/routes/page.tsx create mode 100644 packages/server/src/app/dashboard/settings/page.tsx create mode 100644 packages/server/src/app/dashboard/threads/[threadId]/page.tsx create mode 100644 packages/server/src/app/dashboard/threads/page.tsx create mode 100644 packages/server/src/lib/api-client.ts diff --git a/packages/server/next.config.ts b/packages/server/next.config.ts index e241181..1ce7557 100644 --- a/packages/server/next.config.ts +++ b/packages/server/next.config.ts @@ -1,7 +1,7 @@ import type { NextConfig } from 'next' const nextConfig: NextConfig = { - transpilePackages: ['@openthreads/core', '@openthreads/storage-mongodb'], + transpilePackages: ['@openthreads/core', '@openthreads/storage-mongodb', '@xyflow/react'], // Allow the mongodb package to run in the Node.js runtime (not Edge) serverExternalPackages: ['mongodb'], } diff --git a/packages/server/package.json b/packages/server/package.json index dab0173..dd41c92 100644 --- a/packages/server/package.json +++ b/packages/server/package.json @@ -9,8 +9,12 @@ "test": "bun test" }, "dependencies": { + "@ant-design/icons": "^5.6.0", + "@ant-design/nextjs-registry": "^1.0.1", "@openthreads/core": "workspace:*", "@openthreads/storage-mongodb": "workspace:*", + "@xyflow/react": "^12.4.4", + "antd": "^5.24.6", "mongodb": "^6.0.0", "next": "^15.0.0", "react": "^19.0.0", diff --git a/packages/server/src/app/api/routes/test/route.ts b/packages/server/src/app/api/routes/test/route.ts new file mode 100644 index 0000000..3f179c5 --- /dev/null +++ b/packages/server/src/app/api/routes/test/route.ts @@ -0,0 +1,33 @@ +/** + * POST /api/routes/test — Test which routes match given criteria + */ + +import { NextRequest, NextResponse } from 'next/server';

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements Issue #15 — Integration Testing & Hardening: **Resilience** - `packages/server/src/lib/retry.ts`: Exponential backoff retry utility (`withRetry`, `computeRetryDelay`) with configurable attempts, delays, and per-error `retryable` predicate. - `packages/server/src/lib/fanout.ts`: Extended with `deliverWithRetry` — automatically retries 5xx/network failures; treats 4xx as non-retryable. - `packages/server/src/lib/deduplication.ts`: Idempotent inbound message deduplication via in-memory LRU store with per-entry TTL. Includes platform-specific key builders (Slack, Telegram, WhatsApp, generic). - `packages/server/src/lib/graceful-storage.ts`: `withGracefulStorage` helper catches storage errors and returns a safe fallback; `StorageHealthMonitor` tracks sliding-window error rate for circuit-breaking. - `packages/channels/src/reconnect.ts`: Generic `ReconnectManager` for WebSocket-based adapters (Slack Socket Mode, Discord, etc.) with the same exponential-backoff pattern used by the WhatsApp `SessionManager`. **Adapter Conformance** - `packages/channels/src/conformance-suite.ts`: `runConformanceSuite()` factory generates a standardised Bun test suite for any `ChannelAdapter`. Covers interface shape, capability flags, handler registration, and lifecycle. Handles the different method naming conventions across adapters (Slack/WA/ Discord/Telegram). - `packages/channels/src/mocks/mock-channel-server.ts`: In-process mock servers for Slack, Telegram, and generic HTTP webhooks. Used to simulate platform callbacks in unit and E2E tests. **E2E Test Scenarios (Issue #15 — all 7 scenarios)** - `packages/core/tests/e2e/lifecycle.test.ts`: Full message lifecycle tests exercising all seven E2E scenarios from the issue using `InMemoryStorageAdapter` and core managers (no real HTTP or database). **Unit Tests** - `packages/server/tests/retry.test.ts` - `packages/server/tests/deduplication.test.ts` - `packages/server/tests/graceful-storage.test.ts` - `packages/server/tests/fanout.test.ts` - `packages/channels/tests/reconnect.test.ts` Co-authored-by: claude[bot] --- packages/channels/package.json | 4 +- packages/channels/src/conformance-suite.ts | 226 ++++++ packages/channels/src/index.ts | 4 +- .../channels/src/mocks/mock-channel-server.ts | 324 ++++++++ packages/channels/src/reconnect.ts | 186 +++++ packages/channels/tests/reconnect.test.ts | 214 ++++++ packages/core/tests/e2e/lifecycle.test.ts | 697 ++++++++++++++++++ packages/server/src/lib/deduplication.ts | 158 ++++ packages/server/src/lib/fanout.ts | 59 ++ packages/server/src/lib/graceful-storage.ts | 136 ++++ packages/server/src/lib/retry.ts | 99 +++ packages/server/tests/deduplication.test.ts | 165 +++++ packages/server/tests/fanout.test.ts | 232 ++++++ .../server/tests/graceful-storage.test.ts | 172 +++++ packages/server/tests/retry.test.ts | 171 +++++ 15 files changed, 2845 insertions(+), 2 deletions(-) create mode 100644 packages/channels/src/conformance-suite.ts create mode 100644 packages/channels/src/mocks/mock-channel-server.ts create mode 100644 packages/channels/src/reconnect.ts create mode 100644 packages/channels/tests/reconnect.test.ts create mode 100644 packages/core/tests/e2e/lifecycle.test.ts create mode 100644 packages/server/src/lib/deduplication.ts create mode 100644 packages/server/src/lib/graceful-storage.ts create mode 100644 packages/server/src/lib/retry.ts create mode 100644 packages/server/tests/deduplication.test.ts create mode 100644 packages/server/tests/fanout.test.ts create mode 100644 packages/server/tests/graceful-storage.test.ts create mode 100644 packages/server/tests/retry.test.ts diff --git a/packages/channels/package.json b/packages/channels/package.json index f29ec7a..9dab3e3 100644 --- a/packages/channels/package.json +++ b/packages/channels/package.json @@ -11,7 +11,9 @@ "import": "./dist/index.js", "require": "./dist/index.cjs", "types": "./dist/index.d.ts" - } + }, + "./conformance-suite": "./src/conformance-suite.ts", + "./mocks": "./src/mocks/mock-channel-server.ts" }, "scripts": { "build": "vite build", diff --git a/packages/channels/src/conformance-suite.ts b/packages/channels/src/conformance-suite.ts new file mode 100644 index 0000000..efbde42 --- /dev/null +++ b/packages/channels/src/conformance-suite.ts @@ -0,0 +1,226 @@ +/** + * Shared adapter conformance test suite. + * + * Provides a factory function `runConformanceSuite()` that generates a + * standardised set of Bun tests for any `ChannelAdapter` implementation. + * + * ### Usage + * ```ts + * // In your adapter's conformance.test.ts: + * import { runConformanceSuite } from '@openthreads/channels/conformance-suite';

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Packaging & Deployment: - Dockerfile for OpenThreads server (multi-stage Bun build) - docker-compose.yml production profile (app service, --profile production) - Helm chart scaffold (deploy/helm/openthreads/) with deployment, service, ingress, secret, HPA, serviceaccount templates - create-openthreads scaffold package (bunx create-openthreads ) Observability: - Structured JSON logger with configurable LOG_LEVEL + LOG_FORMAT env vars - Prometheus-compatible metrics endpoint (GET /api/metrics) with counters for messages in/out, A2H intents, fanout, HTTP requests, active threads - OpenTelemetry tracing setup in instrumentation.ts (enabled via OTEL_EXPORTER_OTLP_ENDPOINT, gracefully skipped if SDK not installed) A2H Layer 2 preparation: - Stub types for Layer 2 intents: POLICY, REVOKE, DELEGATE, SCOPE - isLayer1Intent() / isLayer2Intent() type guards - IntentHandlerRegistry extension point in reply-engine/intent-handler.ts for registering custom handlers (Layer 2 or overrides) - Export all new types from @openthreads/core Documentation: - docs/self-hosting.md (Docker, env vars, MongoDB, production checklist) - docs/adapter-authoring.md (ChannelAdapter interface guide) - docs/channels/slack.md, docs/channels/telegram.md Examples: - examples/plain-http/ — minimal Bun webhook consumer with cURL snippets - examples/n8n/ — n8n webhook node integration guide - examples/langgraph/ — LangGraph agent with A2H AUTHORIZE flow (Python) Co-authored-by: claude[bot] --- .env.example | 13 +

This guide explains how to implement a custom adapter for any +platform not natively supported. + +## When do you need a custom adapter? + +- Your platform isn't supported out of the box (WhatsApp via Baileys, Signal, Matrix, etc.) +- You need custom rendering for A2H intents on a supported platform +- You're integrating with an internal messaging system + +## The ChannelAdapter interface + +```typescript +import type { ChannelAdapter } from '@openthreads/core'; + +export class MyAdapter implements ChannelAdapter { + // Report what your platform supports + capabilities(): ChannelCapabilities { ... } + + // Set up webhooks / subscriptions when a channel is registered + async register(config: ChannelConfig): Promise { ... } + + // Send a message to a target (channel, group, user) + async sendMessage(target: string, message: ...): Promise { ... } + + // Render a Chat SDK message in platform-native format + async renderChatSDK(message: ChatSDKMessage, capabilities): Promise { ... } + + // Render an A2H intent as inline interactive elements (buttons, menus) + // Only called for Method 1 (inline rendering) + async renderA2HInline(intent: A2HMessage, capabilities): Promise { ... } + + // Capture a free-text response from the human (Method 2) + async captureResponse(thread: Thread, turn: Turn): Promise { ... } +} +``` + +## Step-by-step: implement a minimal adapter + +### 1. Create a new package + +``` +packages/channels/my-platform/ + src/ + adapter.ts # ChannelAdapter implementation + index.ts # public exports + package.json +``` + +### 2. Declare capabilities + +```typescript +capabilities(): ChannelCapabilities { + return { + threads: false, // does your platform have native threads? + buttons: true, // can you render interactive buttons? + selectMenus: false, // can you render dropdown menus? + replyMessages: true, // can senders reply to specific messages? + dms: true, // does it support DMs? + fileUpload: false, // can you upload files? + }; +} +``` + +The Reply Engine uses these flags to select the best method (1-4) for each +A2H intent. Reporting wrong capabilities leads to degraded UX. + +### 3. Implement `renderChatSDK` + +Map the Chat SDK message to your platform's native format: + +```typescript +async renderChatSDK( + message: ChatSDKMessage, + _capabilities: ChannelCapabilities, +): Promise { + return { + text: message.text ?? '', + // Add platform-specific fields + }; +} +``` + +### 4. Implement `renderA2HInline` (Method 1) + +For `AUTHORIZE` (approve/deny) and `COLLECT` with closed options: + +```typescript +async renderA2HInline( + intent: A2HMessage, + _capabilities: ChannelCapabilities, +): Promise { + if (intent.intent === 'AUTHORIZE') { + return { + text: intent.description ?? 'Action requires your approval', + // Platform-specific button payload + buttons: [ + { id: 'approve', text: 'Approve', value: 'true' }, + { id: 'deny', text: 'Deny', value: 'false' }, + ], + }; + } + // Handle COLLECT with options... +} +``` + +### 5. Implement `captureResponse` (Method 2) + +For free-text collection via thread/reply: + +```typescript +async captureResponse(thread: Thread, turn: Turn): Promise { + // Set up a listener for the next message in this thread from the sender + // This depends heavily on your platform's event system + return new Promise((resolve) => { + // ... platform-specific listener + }); +} +``` + +### 6. Implement `register` + +```typescript +async register(config: ChannelConfig): Promise { + // Store config + // Register webhooks with the platform + // Subscribe to events +} +``` + +## Example: WhatsApp via Baileys + +See `packages/channels/whatsapp/` for a real-world example using the +[Baileys](https://github.com/WhiskeySockets/Baileys) library. + +## Publishing your adapter + +Adapters are standalone npm packages.
