Behind the scenes
How are identified applicable files
- Activated only if sub-directory
force-appis found. (directory name can be overridden withSALESFORCE_DIRECTORY) - If this linter is active, all files will always be linted
How the linting is performed
sfdx-scanner-lwc is called once on the whole project directory (project CLI lint mode)
- filtering can not be done using MegaLinter configuration variables,it must be done using sfdx-scanner-lwc configuration or ignore file (if existing)
VALIDATE_ALL_CODEBASE: falsedoes not make sfdx-scanner-lwc analyze only updated files
Example calls
sfdx scanner:run
