sfdx-scanner-lwc
sfdx-scanner is a sfdx plugin scanning apex and triggers using Apex PMD, and javascript using eslint
If your root folder is not force-app, please set variable SALESFORCE_SFDX_SCANNER_LWC_DIRECTORY
You can select categories and single rules by defining custom arguments (example: SALESFORCE_SFDX_SCANNER_ARGUMENTS: -c "Best Practices,Security")
See more details in Help
Workaround: Restricted to LWC

Configuration in MegaLinter
- Enable sfdx-scanner-lwc by adding
SALESFORCE_SFDX_SCANNER_LWCin ENABLE_LINTERS variable - Disable sfdx-scanner-lwc by adding
SALESFORCE_SFDX_SCANNER_LWCin DISABLE_LINTERS variable
| Variable | Description | Default value |
|---|---|---|
| SALESFORCE_SFDX_SCANNER_LWC_ARGUMENTS | User custom arguments to add in linter CLI call Ex: -s --foo "bar" |
|
| SALESFORCE_SFDX_SCANNER_LWC_COMMAND_REMOVE_ARGUMENTS | User custom arguments to remove from command line before calling the linter Ex: -s --foo "bar" |
|
| SALESFORCE_SFDX_SCANNER_LWC_CLI_LINT_MODE | Override default CLI lint mode ⚠️ As default value is project, overriding might not work - file: Calls the linter for each file- list_of_files: Call the linter with the list of files as argument- project: Call the linter from the root of the project |

| SALESFORCE_SFDX_SCANNER_LWC_CONFIG_FILE | sfdx-scanner-lwc configuration file nameUse LINTER_DEFAULT to let the linter find it |
--eslintconfig |
| SALESFORCE_SFDX_SCANNER_LWC_RULES_PATH | Path where to find linter configuration file | Workspace folder, then MegaLinter default rules |
| SALESFORCE_SFDX_SCANNER_LWC_DISABLE_ERRORS | Run linter but consider errors as warnings | false |
| SALESFORCE_SFDX_SCANNER_LWC_DISABLE_ERRORS_IF_LESS_THAN | Maximum number of errors allowed | 0 |
| SALESFORCE_SFDX_SCANNER_LWC_CLI_EXECUTABLE | Override CLI executable | ['sf'] |

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: falsedoesn't make sfdx-scanner-lwc analyze only updated files
Example calls
sf scanner:run
