    File Nesting Config for VS Code

    File Nesting Config for VS Code

    Config of File Nesting for VS Code

    ...It supports VS Code version 1.67 and above by enabling the built-in "explorer.fileNesting" setting. It is somewhat opinionated, offering a broad list of patterns (for example hiding .env.*, *.freezed.dart, etc) and it also includes an optional VS Code extension to automatically update the nesting config from the repo. Because the snippet is generated via a script (update.mjs), it is maintained for many languages, frameworks, and file types. The benefit is much cleaner project file trees, reduced noise, easier navigation, and less time wasted hunting through duplicate or generated files.
