7.71 Update Dockerfile for TypeScript Build

Summary

Update the backend Dockerfile to build and run the TypeScript-based backend. Ensure the image compiles TypeScript, runs Prisma migrations if needed, and starts the compiled Node server in a production-appropriate environment.

Tasks

• Review the migration roadmap for Docker and build requirements
• Update Dockerfile base image to a supported Node LTS version
• Configure build stage:
  - Set working directory
  - Copy package.json, pnpm-lock.yaml, and pnpm config
  - Install dependencies with pnpm install --frozen-lockfile
  - Copy source files (app/, prisma/, tsconfig.json, etc.)
  - Run TypeScript build (pnpm build or npx tsc)
• Configure runtime stage:
  - Copy compiled output (e.g., dist/) and minimal runtime dependencies
  - Copy prisma artifacts if required (e.g., node_modules/.prisma)
  - Set environment variables and NODE_ENV=production
  - Set CMD to run compiled server entrypoint (e.g., node dist/app/server.js)
• Ensure Dockerfile uses .dockerignore to exclude unnecessary files (node_modules, tests, local artifacts)
• If using Prisma:
  - Optionally run prisma migrate deploy or prisma generate in the image or entry script
• Build and run the image locally for verification
• Commit Dockerfile changes

Expected Behavior

The Docker image builds the TypeScript backend, runs the compiled server, and supports Prisma and other runtime dependencies in a production context.

Tech Notes

• Prefer a multi-stage Docker build to keep the runtime image small.
• Align Docker build commands with package.json scripts used for local builds.

Acceptance Criteria

• docker build for the backend image completes successfully
• Running the container starts the compiled server and serves GraphQL/HTTP endpoints
• Container logs show correct startup with TypeScript build artifacts

Test Instructions

1. Run pnpm test locally before building the image.
2. Build the Docker image: docker build -t quote-vote-backend:ts .
3. Run the container: docker run -p 4000:4000 quote-vote-backend:ts
4. Hit health and GraphQL endpoints from the host to confirm behavior.
5. Optionally, run a minimal smoke test suite inside the container or against the running container.
