CircleCI - Scan your code for unused feature flags

ConfigCat's CircleCI Orb has the ability to scan your source code for feature flag and setting usages and upload the found code references to ConfigCat.

This feature makes the elimination of the technical debt easier, as it can show which repositories reference your feature flags and settings in one centralized place on your Dashboard.

Here you can find more details about how this feature works.

This section describes how to use ConfigCat's CircleCI Orb to automatically scan your source code for feature flag and setting usages and upload the found code references to ConfigCat. You can find more information about CircleCI Orbs here.

Setup

  1. Create a new ConfigCat Management API credential and store its values in CircleCI Environment Variables with the following names: CONFIGCAT_API_USER, CONFIGCAT_API_PASS.

  2. Get your selected Config's ID.

  3. Create a new CircleCI YAML config in your repository under the .circleci folder, and put the following snippet into it. Don't forget to replace the PASTE-YOUR-CONFIG-ID-HERE value with your actual Config ID.

    version: 2.1

    orbs:
    configcat: configcat/scan-[email protected]

    workflows:
    main:
    jobs:
    - configcat/scan:
    config-id: PASTE-YOUR-CONFIG-ID-HERE # required
    file-url-template: 'https://github.com/your/repo/blob/{commitHash}/{filePath}#L{lineNumber}' # optional
    commit-url-template: 'https://github.com/your/repo/commit/{commitHash}' # optional
    # line-count: 3 # optional
    # sub-folder: 'src' # optional
    # exclude-keys: > # optional
    # flag_key_to_exclue_1
    # flag_key_to_exclue_2
    # verbose: true # optional
  4. Commit & push your changes.

The above example configures a workflow that executes the scan and code reference upload on every git push event. Scan reports are uploaded for each branch of your repository that triggers the workflow.
