Proof of Concept - Watchlistarr API

[nylonee]

Added an API to allow sending new configuration to Watchlistarr.

Can be used to prototype and experiment with building a GUI

Example cURL command:

curl --location --request PATCH 'localhost:3434/config' \
--header 'Content-Type: application/json' \
--data '{
    "interval.seconds": "30"
}'

Walkthrough

The project updates focus on enhancing Watchlistarr's Docker configuration, adding new dependencies, optimizing the Dockerfile, and introducing a dynamic configuration update mechanism via HTTP PATCH requests. These changes improve the build efficiency, extend functionality, and offer more customization and debug options, significantly enhancing the application's flexibility and user experience.

Changes

Files	Change Summary
.gitignore	Added config/ to ignore the config directory.
README.md	Updated Docker configuration instructions, including environment variable and config.yaml changes.
build.sbt	Added new dependencies for various libraries.
docker/Dockerfile	Optimized the build process by reordering COPY and RUN commands.
src/main/scala/Routes.scala src/main/scala/Server.scala src/main/scala/configuration/...	Introduced dynamic configuration updates, refactored server setup, and added configuration readers.

🐇✨

In the realm of code, where changes abound,
A rabbit hopped in, improvements were found.
With a flick and a hop, the Docker refined,
Configurations danced, dynamically aligned.
Through the maze of code, with a joyful bound,
It left things better, more robust, and sound.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit-tests for this file.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit tests for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository from git and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit tests.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• The JSON schema for the configuration file is available here.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json

Additional comments: 8

src/main/scala/configuration/SystemPropertyReader.scala (1)

• 4-4: Adding the override keyword enhances clarity and ensures that SystemPropertyReader correctly implements the method from ConfigurationReader. Good practice for maintaining code readability and safety.

src/main/scala/configuration/MapReader.scala (1)

• 3-7: The implementation of MapAndFileAndSystemPropertyReader provides a clear and efficient way to layer configuration sources, first attempting to retrieve from the provided map and then falling back to file and system properties if necessary. This is a solid approach for flexible configuration management.

docker/Dockerfile (1)

• 5-7: The reordering and modification of COPY and RUN commands in the Dockerfile are likely aimed at optimizing the build process by leveraging Docker's layer caching more effectively. Ensure thorough testing of the Docker build process to confirm the optimizations achieve the desired improvements without introducing issues.

src/main/scala/Routes.scala (1)

• 11-27: The implementation of dynamic configuration updates via HTTP PATCH requests in Routes.scala is well-structured and logically sound. However, consider adding explicit error handling to gracefully manage any failures during the configuration update process, ensuring a clear response is sent back to the client in case of errors.

build.sbt (1)

• 14-40: > 📝 NOTE

This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [17-49]

The addition of new dependencies (ip4s-core, snakeyaml, http4s-ember-server, http4s-dsl, and http4s-server) is aligned with the PR objectives to enhance server functionality and support dynamic configuration management. Ensure to check for any potential dependency conflicts or compatibility issues with the project's existing dependencies.

src/main/scala/Server.scala (1)

• 24-71: The refactoring in Server.scala, including the introduction of configRef and the separation of server setup logic, significantly improves the maintainability and modularity of the configuration management system. Ensure to review the concurrent access to configRef to prevent potential data races, especially given the asynchronous nature of the operations involved.

src/main/scala/configuration/FileAndSystemPropertyReader.scala (1)

• 11-83: The implementation in FileAndSystemPropertyReader for managing configurations from files and system properties is well-structured and follows good practices, including proper resource management and handling of nested YAML structures. Consider reviewing the logging levels, especially for missing critical resources like config-template.yaml, to ensure important issues are adequately highlighted.

README.md (1)

• 90-110: > 📝 NOTE

This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [55-107]

The updates to the Docker configuration instructions and the addition of debug mode instructions in the README.md are clear and align with the PR's objectives of enhancing flexibility and customization. These changes improve the documentation's usefulness for users looking to configure and troubleshoot Watchlistarr. Consider adding examples or further clarification if necessary to ensure users can easily follow the instructions.
