Build configuration needs attention
The publish configuration in package.json needs adjustment because:
- The build directory doesn't exist yet, but it's configured as the output directory in tsconfig.json
- The current publish config in package.json uses
ignorewhich is not a valid npm publish configuration field- The .npmignore file already handles most exclusions properly
Suggested changes:
- Replace
"ignore"with"files"in package.json's publishConfig and include only the build directory:"publishConfig": { "files": ["build/"] }
- Or remove the publishConfig section entirely since .npmignore already handles the exclusions correctly

The engine requirement of Node.js >=22.0.0 is very recent. This could impact Docker builds and deployments.
Consider:
- Ensuring the Docker base image supports Node.js 22
- Documenting this requirement prominently in README.md
- Adding version checks in the startup script
✅ Verification successful
Docker configuration aligns with Node.js version requirement
The Dockerfile is already configured correctly using node:22-alpine as the base image, which matches the Node.js >=22.0.0 engine requirement in package.json. The configuration is consistent across both build and runtime stages.

💡 Codebase verification
Path resolution needs to be updated for Docker compatibility
The current path ../build/src/daemon.js in bin/peblar2mqtt is inconsistent with the Docker setup. The Dockerfile copies the build output to /app/dist and runs dist/src/daemon.js, while the local development uses the build directory. The path should be aligned with both environments.
bin/peblar2mqtt: Update import path to use environment-aware resolution instead of a hard-coded relative path- Consider using
process.env.NODE_ENVto determine the correct path or use a configuration file
🔗 Analysis chain
Verify path resolution in Docker environment
The path change aligns with the new build structure, but we should verify that this relative path works correctly both in local development and within the Docker container.
Let me gather more information about the build structure and Docker configuration to better understand the path resolution.
Let me check the Dockerfile content to understand the build and runtime environment setup.

Docker doesn't use this file, so we can probably ignore it for now

@itavero, understood. We'll ignore the path mismatch in “bin/peblar2mqtt” for now, given that Docker doesn’t rely on this script. Thanks for clarifying!

💡 Codebase verification
The Dockerfile's CMD path needs to be updated to match the build output directory
The tsconfig.json shows the output directory as ./build, and this is confirmed by the start script in package.json which runs node build/src/daemon.js. However, the Dockerfile's CMD is using dist/src/daemon.js. This path mismatch will cause the container to fail at runtime.
- Update the CMD in Dockerfile to use
build/src/daemon.jsinstead ofdist/src/daemon.js

@coderabbitai Since we switched to the alpine image one of the ARM builds hangs. Perhaps we should switch to the slim image? |
|
Tip For best results, initiate chat on the files or code changes. @itavero: Switching to the Slim variant may resolve ARM build issues. One possible approach is to modify both stages in your Dockerfile from node:22-alpine to node:22-slim, for example: FROM node:22-slim AS build

2-2: LGTM! The switch to slim variant should help with ARM builds.
The change from Alpine to Slim is a good choice as it provides better ARM compatibility while maintaining a relatively small image size.
Let's verify the image supports all required architectures:
✅ Verification successful
✅ Verified: The node:22-slim image fully supports ARM architectures
The manifest shows that node:22-slim supports both ARM architectures needed:
- arm64 (v8) for 64-bit ARM
- arm (v7) for 32-bit ARM
This confirms the switch from Alpine to Slim will work correctly for ARM builds.

# Expected: Should see arm64 and arm/v7 in the list of supported architectures

The CMD path has been updated to dist/src/daemon.js, but we need to ensure the COPY command preserves this structure.

Also applies to: 19-19
✅ Verification successful
Build output path structure is correctly aligned
The path structure is correctly configured:
- Source file exists at
src/daemon.ts - TypeScript
outDiris set to./build - Dockerfile copies from
/app/buildto/app/dist - CMD correctly references
dist/src/daemon.js
The COPY command will preserve the directory structure from the build output, maintaining the src subdirectory. The path in the CMD statement matches this structure.

🧹 Nitpick (assertive)
Consider pinning to a specific version for better reproducibility.
The change to slim is good, but using a floating tag like 22-slim could lead to unexpected issues if the base image is updated.
Consider using a specific version like:
-FROM node:22-slim
+FROM node:22.4.0-slimCommittable suggestion skipped: line range outside the PR's diff.
