Custom “House Style” Rules
Customize the JavaScript style rules that force:lightning:lint applies to your code.
It’s common that different organizations or projects will adopt different JavaScript rules. Lightning component validations help you work with Lightning component APIs, not enforce Salesforce coding conventions. To that end, the validation rules are divided into two sets, security rules and style rules. The security rules can’t be modified, but you can modify or add to the style rules.
Use the --config argument to provide a custom rules configuration file. A custom rules configuration file allows you to define your own code style rules, which affect the style rules used by force:lightning:lint.
The default style rules are provided below. Copy the rules to a new file, and modify them to
match your preferred style rules. Alternatively, you can use your existing ESLint rule
configuration file directly. For
example:
1sfdx force:lightning:lint ./path/to/lightning/components/ --config ~/.eslintrcDefault Style Rules
Here are the default style rules used by force:lightning:lint.
