LWC Space CleanerA VS Code extension that safely removes trailing spaces and converts leading indentation
spaces → tabs only in Lightning Web Component Author: Monoranjan Choudhury Why it is safeJavaScript is not Apex — whitespace can be part of a string's value. This extension is JS-aware: a line is only modified when its leading/trailing whitespace is in code context. Lines inside template literals, block comments or strings are never touched, so string values can never change. Features
