- Full failing message: process "/bin/sh -c npx babel src --out-dir dist" did not complete successfully: exit code: 1
- Exact error message (preserved):
- " You have mistakenly installed the `babel` package, which is a no-op in Babel 6.
- Babel's CLI commands have been moved from the `babel` package to the `babel-cli` package.
npm uninstall babel
npm install --save-dev babel-cli
- See http://babeljs.io/docs/usage/cli/ for setup instructions."
- Missing packages or files mentioned:
- The babel package is installed but no longer provides the CLI in Babel 6.
- Suggested fix indicates babel-cli is needed (i.e., install babel-cli or update dependencies).
- Version mismatch info:
- Babel 6 behavior: the babel package is a no-op for CLI.
- CLI has moved to the babel-cli package; using npx babel with the old babel package installed causes this error.# syntax=docker/dockerfile:1 FROM node:22.22.3-alpine3.23 AS builder WORKDIR /app # Install dependencies and build from source COPY package.json .

Concerns: Final image copies only dist and package.json; runtime dependencies (if any) may not be present, e.g., Babel runtime; ensure dist is self-contained., Smoke tests assume a usable export from dist; if the library's API is different, tests may fail and should be updated.

Concerns: COPY . . in the builder stage may copy host-specific node_modules and other artifacts; add a .dockerignore to exclude node_modules and possibly build artifacts for a cleaner build context., Relying on babel-cli as a devDependency is fine for builds, but consider using a lean production image approach (e.g., npm ci --only=production in a separate step) if image size is a concern. The final image currently ships only dist and package.json, which is good.

Concerns: The builder's final 'RUN mkdir -p dist && cp -R src dist/index.js' copies a directory into dist/index.js, effectively creating a directory at that path instead of a single JavaScript file. This breaks runtime require('./dist/index.js') since Node expects a file/module at that path., The runtime CMD assumes dist/index.js is a valid entrypoint module, but the preceding copy/copy-from-builder steps do not guarantee that a proper dist/index.js file exists., Suggestion: ensure dist/index.js is a real file (e.g., 'RUN mkdir -p dist && cp -R src/index.js dist/index.js' or 'COPY src/index.js dist/index.js') and that dist/index.js exports the library correctly.const Choreographer = require('./Choreographer')

Concerns: Final stage does not copy runtime node_modules from the builder; requiring ./dist/index.js will fail if the library has runtime dependencies not installed in the final image., The final image only copies dist and package.json; dependencies installed in builder stage are unused. You should copy /build/node_modules or install production dependencies in the final stage., If the library relies on a build step (e.g., transpiling to dist), this approach bypasses it; currently there is no transpilation, but it's worth verifying against the repo's expectations.

Concerns: Final runtime image only contains dist; if dist/index.js or its dependencies require node_modules at runtime, those won't be present., The smoke tests rely on loading dist/index.js but do not exercise a specific API due to unknown library surface; consider adding API-based smoke tests once API is known.

CMD ["node", "verify.js"]
Concerns: The build step uses bash -lc to create verify.js, but Alpine-based images (node:...-alpine) typically do not include bash by default; this will cause the Docker build to fail. Use sh -lc or install bash explicitly., The Babel CLI is installed via npm install babel-cli --save-dev, which may be outdated for Babel 7+ (prefer @babel/cli if the project uses Babel 7+). This is not a functional blocker by itself, but could lead to mismatches between build tooling and dependencies., The final image runs a smoke test on startup (CMD node verify.js). If the container is intended as a library artifact, consider whether auto-running a smoke test on startup is desirable; otherwise, ensure this aligns with intended usage.
