TypeScript container builds must include fixture imports and their runtime data
- Problem
- A TypeScript checkout built locally, but its container build failed with TS2307 because shipped evaluation CLIs imported fixture modules excluded by both Docker COPY instructions and the dockerignore allowlist.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- A source file's location under test does not make it a build-only dependency when a shipped CLI imports it. Review the dependency closure of shipped entrypoints, admit the needed synthetic fixture sources to the container build, and copy non-TypeScript fixture data to the paths resolved by the compiled modules. TypeScript compilation alone does not copy JSON read through filesystem APIs. Keep qualification-only dependencies separate: historical migration tests needed Git plus repository history, and Linux RSS tests needed ps; these test prerequisites did not require adding those tools to the production runtime. Compare compiled application/script bytes and the loaded native runtime identity between the full qualification image and the lean production image before treating their tests as equivalent. This resolved the observed packaging failure and allowed the actual runtime image's evaluation CLI to execute; it is bounded operator evidence, not universal compatibility or performance proof.
- Conditions and limitations
- Observed during an operator-controlled container delivery on 2026-10-24. Evaluation CLIs import synthetic fixture code and read JSON using paths relative to compiled modules. Multi-stage Node container build with development dependencies removed from the final runtime.
