Walkthrough

Adds Cloudflare Workers deployment: a new wrangler TOML, a build script step to bundle a worker, and a new worker adapter that loads the Express app and maps Worker requests/responses to Node-style req/res for runtime execution.

Changes

Cohort / File(s) Summary
Deployment Configuration
deploy/system-wrangler.toml
New Cloudflare Wrangler config: project metadata, node_compat = true, compatibility date/flags, workers_dev = false, route finance.chitty.cc/*, declared environment variables and secret placeholders, resource limit cpu_ms = 50000, build pipeline (command "npm run build:system"), and upload.format = "modules".
Build Configuration
package.json
Updated build:system script to append an esbuild step that bundles server/worker.ts for a browser target into dist/system, keeping the existing system build step.
Worker Adapter Implementation
server/worker.ts
New Cloudflare Worker entrypoint exporting default { fetch(request, env, ctx) }: sets env vars (NODE_ENV, MODE, DATABASE_URL, OPENAI_API_KEY, CHITTYCONNECT_API_BASE, CHITTY_AUTH_SERVICE_TOKEN), dynamically imports the Express app (index.js), creates mock Node-style req/res, dispatches to Express, converts the Express response to a Cloudflare Response, and returns JSON 500 on errors.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

  • Inspect server/worker.ts for correct request/response translation, body streaming, header handling, and error serialization.
  • Verify package.json esbuild options and output path align with deploy/system-wrangler.toml.
  • Check deploy/system-wrangler.toml syntax, upload.format = "modules", route, and declared secret names.

Poem

🐇 I hopped a bridge from Node to cloud,
I set some env and called the crowd.
I mock, I import, I route the tide,
Express in a worker — swift and wide.
Finance paths now softly prance and bow.

Pre-merge checks and finishing touches

❌ Failed checks (1 inconclusive)
Check name Status Explanation Resolution
Title check ❓ Inconclusive The title describes deploying and verifying ChittyConnect integration, but the actual changes focus on configuring Cloudflare Workers deployment and integrating an Express app adapter—not specifically ChittyConnect verification. Clarify whether the title should emphasize the Cloudflare Workers deployment aspect or specify what ChittyConnect integration verification entails in the changeset.

15-20: Note: Process.env population concern already tracked.

This manual assignment of environment variables to process.env has been flagged in previous reviews and you've created an issue to track it.


23-23: Note: Missing export concern already tracked.

Previous reviews identified that server/index.ts doesn't export the Express app, causing this import to fail. You've created an issue to track this critical blocker.


34-82: Note: Incomplete Express adapter concerns already documented.

The limitations of this minimal mock request/response adapter have been comprehensively covered in previous reviews, including missing stream methods, incomplete body handling, and missing Express response helpers. These architectural concerns remain valid.

83-94: Error handling correctly avoids leaking sensitive details.

The error handler appropriately returns only a generic error message to clients while logging full details server-side. This addresses the concern raised in previous reviews about leaking stack traces or implementation details.
