JSCS - JavaScript Code Style Checker - security Cheatsheets

JSCS (JavaScript Code Style Checker) is a powerful tool designed to enforce consistent coding styles across your JavaScript projects. By defining and enforcing a set of rules, JSCS helps teams maintain code readability, reduce bugs, and improve overall code quality. This guide provides essential commands and usage examples for JSCS.

JSCS Command Line Usage

JSCS can be used directly from the command line to check and fix code style issues in your JavaScript files.

Checking a Single File

To check a single JavaScript file for code style violations, use the following command:

jscs path/to/file.js

Checking a Directory

To check all JavaScript files within a specific directory, use:

jscs path/to/directory

Checking Multiple Files

You can specify multiple files to check simultaneously:

jscs file1.js file2.js file3.js

Using a Configuration File

JSCS allows you to define your coding standards in a configuration file (e.g., .jscsrc). To use a specific configuration file:

jscs --config path/to/.jscsrc path/to/file.js

Automatically Fixing Style Violations

JSCS can automatically fix many common style issues. Use the --fix flag to apply these fixes:

jscs --fix path/to/directory

Custom Reporters

For advanced reporting needs, you can specify a custom reporter:

jscs --reporter path/to/custom-reporter.js path/to/file.js

JSCS Help and Version

To get a list of all available rules and options, use the --help flag:

jscs --help

To check the installed version of JSCS, use:
