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")

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
- 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
Help content
evaluate a selection of rules against a codebase
USAGE
$ sfdx scanner:run -t <array> [-c <array>] [-r <array>] [-e <array>] [-f
csv|html|json|junit|sarif|table|xml] [-o <string>] [--tsconfig <string>]
[--eslintconfig <string>] [--pmdconfig <string>] [--env <string>] [-s
<integer> | | [-v | --json]] [--normalize-severity] [--verbose] [--loglevel
trace|debug|info|warn|error|fatal|TRACE|DEBUG|INFO|WARN|ERROR|FATAL]
OPTIONS
-c, --category=category
categor(ies) of rules to run
-e, --engine=engine
engine(s) to run
-f, --format=(csv|html|json|junit|sarif|table|xml)
format of results
-o, --outfile=outfile
location of output file
-r, --ruleset=ruleset
[deprecated] ruleset(s) of rules to run
-s, --severity-threshold=severity-threshold
throws an error when violations of specific severity (or more severe) are
detected, invokes --normalize-severity
-t, --target=target
(required) location of source code
-v, --violations-cause-error
[deprecated] throws an error when violations are detected
--env=env
JSON-formatted string, overrides ESLint's default environment variables
--eslintconfig=eslintconfig
location of eslintrc config to customize eslint engine
--json
format output as json
--loglevel=(trace|debug|info|warn|error|fatal|TRACE|DEBUG|INFO|WARN|ERROR|FATA
L)
[default: warn] logging level for this command invocation
--normalize-severity
A normalized severity 1 (high), 2 (moderate), and 3 (low) is returned in
addition to the engine specific severity
--pmdconfig=pmdconfig
location of PMD rule reference XML file to customize rule selection
--tsconfig=tsconfig
location of tsconfig.json file
--verbose
emit additional command output to stdout
EXAMPLE
Invoking without specifying any rules causes all rules to be run.
E.g., $ sfdx scanner:run --format xml --target "somefile.js"
Evaluates all rules against somefile.js.
Specifying multiple categories is treated as a logical OR.
E.g., $ sfdx scanner:run --format xml --target "somefile.js" --category
"Design,Best Practices"
Evaluates all rules in the Design or Best Practices categories.
Categories can be excluded by specifying the negation operator, the values
must be enclosed in single quotes.
E.g., $ sfdx scanner:run --format xml --target "somefile.js" --category
'!Design,!Best Practices'
Evaluates all rules except those in the Design or Best Practices categories.
Wrap globs in quotes.
Unix example: $ sfdx scanner:run --target './**/*.js,!./**/IgnoreMe.js' ...
Windows example: > sfdx scanner:run --target ".\**\*.js,!.\**\IgnoreMe.js" ...
Evaluate rules against all .js files below the current directory, except for
IgnoreMe.js.
Specify tsconfig.json if the current working directory does not contain the
tsconfig.json that corresponds to the TypeScript files being scanned.
E.g., sfdx scanner:run --target "/my-project/**/*.ts" --tsconfig
"/my-project/tsconfig.json"
Scans the project contained in '/my-project' if the current working directory
is another directory.
Use --env to override the default ESLint environment variables to add
frameworks.
E.g., $ sfdx scanner:run --target "somefile.js" --env '{"jasmine": true}'
Evaluates rules against somefile.js, including Jasmine in the environment
variables.
Use --violations-cause-error to throw exit with a non-zero code when
violations are found.
E.g., $ sfdx scanner:run --target "somefile.js" --violations-cause-error
Evaluates rules against somefile.js. If any rules are violated, the exit code
will be the severity of the most severe violation.
Use --engine to include or exclude engines. Any engine listed will be run,
regardless of its current 'disabled' attribute.
E.g., $ sfdx scanner:run --target "somefile.js" --engine "eslint-lwc,pmd"
Evaluates rules against somefile.js, using eslint-lwc and pmd engines.
Use --engine to invoke engines that are not enabled by default.
E.g, $ sfdx scanner:run --target "/some/dir" --engine cpd
Executes CPD engine against known file extensions in "/some/dir". CPD helps
detect blocks of code duplication in selected languages.
To use PMD with your own rule reference file, use --pmdconfig. Note that rule
filters are not applied.
E.g, $ sfdx scanner:run --target "src" --pmdconfig "pmd_rule_ref.xml"
To use Eslint with your own .eslintrc.json file, use --eslintconfig. Make sure
that the directory you run the command from has all the NPM dependencies
installed.
E.g., $ sfdx scanner:run --target "src" --eslintconfig
"/home/my/setup/.eslintrc.json"
Use --normalize-severity to output a normalized (across all engines) severity
(1 [high], 2 [moderate], and 3 [low]) in addition to the engine specific
severity (when shown).
E.g., $ sfdx scanner:run --target "/some-project/" --format csv
--normalize-severity
Use --severity-threshold to throw a non-zero exit code when rule violations of
a specific severity (or greater) are found. For this example, if there are
any rule violations with a severity of 2 or more (which includes 1-high and
2-moderate), the exit code will be equal to the severity of the most severe
violation.
E.g., $ sfdx scanner:run --target "/some-project/" --severity-threshold 2
WARNING: In September 2022, v3.x of the Salesforce Code Analyzer will become the default version,
and older versions, including your currently installed version, will no longer be supported.
You can manually update to v3.x earlier for a smoother transition.
WARNING: As of April 27, 2022, v3.x of the Salesforce Code Analyzer is available as an open pilot.
To update to v3.x and try out our pilot features, run these commands:
> sfdx plugins:uninstall @salesforce/sfdx-scanner
