Gitignore for Dash apps
This example demonstrates a comprehensive `.gitignore` configuration for Dash applications, organizing ignore rules by category such as Python bytecode, virtual environments, IDE settings, and platform-specific files. The code excludes common generated artifacts like `__pycache__`, `.venv`, `.env`, and Jupyter checkpoint folders, while leaving commented placeholders for potential data files. It leverages standard Git ignore syntax with globbing patterns, including optional exclusions for project-specific directories when needed.
