Hello everyone! Today, I'd like to introduce a CLI tool I developed that automatically detects unused Unleash flags. By using this tool, you can easily identify outdated feature flags in your project and help clean up your codebase.
Tool Overview
- Repository: stale-flag-detector
- Function: Automatically detects unused Unleash flags
-
Installation: Clone the repository and generate the executable using the
go buildcommand
Basic Usage
After building the tool, you can display a list of stale flags by running it as follows:
% ./stale-flag-detector
Stale flags:
- unleash-ai-example-stale
- another-stale-flag
Options
This tool has two main options:
-
--exclude-potentially-stale-flags- Excludes potentially stale flags from the results
- For more details on potentially stale flags, please refer to the Unleash documentation
-
--output-regex- Outputs the results in regex format
Example of Regex Output
% ./stale-flag-detector --output-regex
(unleash-ai-example-stale|another-stale-flag)
Practical Usage Example
The true value of this tool is realized when combined with other command-line tools. For example, by combining it with the pt command (The Platinum Searcher), you can easily identify where stale flags are being used in your project:
% pt -e `./stale-flag-detector --output-regex` ../sample-app-for-unleash-checker
../sample-app-for-unleash-checker/app/stale.py
9:if client.is_enabled("unleash-ai-example-stale"):
Using this method provides the following advantages:
- Accurately locate unused flags
- Simplify codebase cleanup
- Contribute to reducing technical debt
Summary
The stale-flag-detector is a powerful tool for streamlining the maintenance of projects using Unleash. It can help improve feature flag management and keep your codebase clean. Give it a try!
