Claude Code deployment rescue

Claude Code app works locally but will not deploy

Walkthrough

1. 01

   Audit what Claude Code produced

   Claude Code generates code but may not set up production build and deploy config.

   • Check package.json for build and start scripts.
   • Confirm the Node version matches what the app expects.
   • List every environment variable the app reads from process.env.
2. 02

   Set up the production server

   The server needs dependencies, env vars, and a process manager.

   • Install all dependencies with the same package manager used locally.
   • Add environment variables to the server deploy panel.
   • Set up a process manager to keep the app alive.
3. 03

   Build, deploy, and test

   Run the production build and verify every integration works.

   • Build the app on the server with production env vars loaded.
   • Start the process and confirm it responds on the expected port.
   • Test database connections, auth, and any external API calls.
