What This Project Is

Real-time global intelligence dashboard. TypeScript SPA (Vite + Preact) with 86 panel components, 60+ Vercel Edge API endpoints, a Tauri desktop app with Node.js sidecar, and a Railway relay service. Aggregates 30+ external data sources (geopolitics, military, finance, climate, cyber, maritime, aviation).

How to Run

npm install              # Install deps (also runs blog-site postinstall)
npm run dev              # Start Vite dev server (full variant)
npm run dev:tech         # Start tech-only variant
npm run typecheck        # tsc --noEmit (strict mode)
npm run typecheck:api    # Typecheck API layer separately
npm run test:data        # Run unit/integration tests
npm run test:sidecar     # Run sidecar + API handler tests
npm run test:e2e         # Run all Playwright E2E tests
make generate            # Regenerate proto stubs (requires buf + sebuf plugins)

Architecture Rules

Dependency Direction

types -> config -> services -> components -> app -> App.ts

• types/ has zero internal imports
• config/ imports only from types/
• services/ imports from types/ and config/
• components/ imports from all above
• app/ orchestrates components and services

API Layer Constraints

• api/*.js are Vercel Edge Functions: self-contained JS only
• They CANNOT import from ../src/ or ../server/ (different runtime)
• Only same-directory _*.js helpers and npm packages
• Enforced by tests/edge-functions.test.mjs and pre-push hook esbuild check

Server Layer

• server/ code is bundled INTO Edge Functions at deploy time via gateway
• server/_shared/ contains Redis client, rate limiting, LLM helpers
• server/worldmonitor/<domain>/ has RPC handlers matching proto services
• All handlers use cachedFetchJson() for Redis caching with stampede protection

Proto Contract Flow

proto/ definitions -> buf generate -> src/generated/{client,server}/ -> handlers wire up

• GET fields need (sebuf.http.query) annotation
• repeated string fields need parseStringArray() in handler
• int64 maps to string in TypeScript
• CI checks proto freshness via .github/workflows/proto-check.yml

Variant System

The app ships multiple variants with different panel/layer configurations:

• full (default): All features
• tech: Technology-focused subset
• finance: Financial markets focus
• commodity: Commodity markets focus
• happy: Positive news only

Variant is set via VITE_VARIANT env var. Config lives in src/config/variants/.

Key Patterns

Adding a New API Endpoint

1. Define proto message in proto/worldmonitor/<domain>/
2. Add RPC with (sebuf.http.config) annotation
3. Run make generate
4. Create handler in server/worldmonitor/<domain>/
5. Wire handler in domain's handler.ts
6. Use cachedFetchJson() for caching, include request params in cache key

Adding a New Panel

1. Create src/components/MyPanel.ts extending Panel
2. Register in src/config/panels.ts
3. Add to variant configs in src/config/variants/
4. Wire data loading in src/app/data-loader.ts

Circuit Breakers

• src/utils/circuit-breaker.ts for client-side
• Used in data loaders to prevent cascade failures
• Separate breaker per data domain

Caching

• Redis (Upstash) via server/_shared/redis.ts
• cachedFetchJson() coalesces concurrent cache misses
• Cache tiers: fast (5m), medium (10m), slow (30m), static (2h), daily (24h)
• Cache key MUST include request-varying params

Testing

• Unit/Integration: tests/*.test.{mjs,mts} using node:test runner
• Sidecar tests: api/*.test.mjs, src-tauri/sidecar/*.test.mjs
• E2E: e2e/*.spec.ts using Playwright
• Visual regression: Golden screenshot comparison per variant

CI Checks (GitHub Actions)

Workflow	Trigger	What it checks
typecheck.yml	PR + push to main	tsc --noEmit for src and API
lint.yml	PR (markdown changes)	markdownlint-cli2
proto-check.yml	PR (proto changes)	Generated code freshness
build-desktop.yml	Manual	Tauri desktop build
test-linux-app.yml	Manual	Linux AppImage smoke test

Pre-Push Hook

Runs automatically before git push:

1. TypeScript check (src + API)
2. CJS syntax validation
3. Edge function esbuild bundle check
4. Edge function import guardrail test
5. Markdown lint
6. MDX lint (Mintlify compatibility)
7. Version sync check

Deployment

• Web: Vercel (auto-deploy on push to main)
• Relay/Seeds: Railway (Docker, cron services)
• Desktop: Tauri builds via GitHub Actions
• Docs: Mintlify (proxied through Vercel at /docs)

Critical Conventions

• fetch.bind(globalThis) is BANNED. Use (...args) => globalThis.fetch(...args) instead
• Edge Functions cannot use node:http, node:https, node:zlib
• Always include User-Agent header in server-side fetch calls
• Yahoo Finance requests must be staggered (150ms delays)
• New data sources MUST have bootstrap hydration wired in api/bootstrap.js
• Redis seed scripts MUST write seed-meta:<key> for health monitoring
