A Danger plugin for reporting iOS and Android app size violations.

$ gem install danger-app_size_report

Report iOS app size violations given a valid App Thinning Size Report. A valid App Thinning Size Report must be passed to the plugin for accurate functionality.

// Dangerfile

report_path = "/Path/to/AppSizeReport.txt"
app_size_report.flag_ios_violations(
    report_path,
    build_type: 'App',
    limit_size: 4,
    limit_unit: 'GB',
    fail_on_warning: false
)

The list of variants with their sizes and any violations will be displayed in the PR report as seen below. Additionally, the report will include warnings for any variants that exceed the optimal size limit for cellular downloads (200 MB). Supported variant descriptors are placed under collapsible sections.

• report_path [String, required] Path to valid App Thinning Size Report text file.
• build_type [String, optional] [Default: 'App'] Specify whether the report corresponds to an App or an App Clip.
  • Supported values: 'App', 'Clip'
• limit_size [Numeric, optional] [Default: 4] Specify the app size limit. If the build type is set to 'Clip' and the specified app size limit exceeds 15 MB, the 15 MB limit will be enforced to meet Apple's App Clip size requirements.
• limit_unit [String, optional] [Default: 'GB'] Specific the unit for the given size limit.
  • Supported values: 'KB', 'MB', 'GB'
• fail_on_warning [Boolean, optional] [Default: false] Specify whether the PR should fail if one or more app variants exceed the given size limit. By default, the plugin issues a warning in this case.
