🔧 --fix

This eslint parameter fix simple rules of linter and with this plugin convert all camelCase variables or function name to snake_case. Fix command support whitelist. Run this command in your project directory:

eslint ./ --cache --ignore-pattern .gitignore --fix

WARNING: You need install eslint globally for this feature: npm install eslint -g

📋 White list

Ignore variables, methods, etc... without snake_case syntax. Add to settings: "snakecasejs/whitelist": ["NewPageClass"] with array of variables with camelCase that you can not convert to snake_case (example: for external library naming convention).

Plugin ignore check on this variables/methods. Example: "snakecasejs/whitelist": ["externalPath","setNumber"]

🚬 Filter

Ignore global checks for class declarations, all methods, etc... Add to settings: "snakecasejs/filter": [] with array of eslint expression or declaration, default value: ["ClassDeclaration", "NewExpression"] for better compatibility with camel case class.
