Development and CLI Lab currently execute TypeScript with Node’s strip-only loader, which rejects constructor parameter properties with ERR_UNSUPPORTED_TYPESCRIPT_SYNTAX. Load @oxc-node/core in these entry points so existing TypeScript syntax can run on Node without rewriting application code.

Add the loader explicitly to source-mode isolated executor subprocesses, which run with a restricted environment. Compiled production executors continue to run JavaScript without the loader. Pin Oxc as a development dependency and document the development runtime.

Validation:

• bun run check passed, including after rebasing onto current main.
• Isolated runtime tests: 54 passed, including after rebasing.
• bun run lab test passed before rebasing.
• Development server startup, source-change restart, and API response after restart passed before rebasing.
• Server production build passed; compiled isolated executor returned the expected result under Node without a TypeScript loader before rebasing.
• bun run test:docker was attempted but blocked before project build by a Docker Hub authentication endpoint connection reset. Container validation remains outstanding.

Summary by CodeRabbit

• Development
  • TypeScript development code now runs directly on Node.js, including isolated runtime execution. Production continues to use compiled JavaScript, and type checking remains a separate step.
• Documentation
  • Updated development setup instructions to explain the runtime and type-checking workflow.

Walkthrough

Development Node.js launch commands now preload @oxc-node/core/register. The isolated runtime executor adds the loader when the module path ends in .ts. The contribution guide distinguishes development transpilation from production JavaScript and states that type checking runs separately with bun run check.

Priority: Normal
