Best Practices for Sharing Code Online
Always format your code with proper indentation and consistent style. Use prettier or similar tools to ensure readability.
Include context about what the code does, why certain decisions were made, and any dependencies or setup instructions.
Never share API keys, passwords, or other sensitive data. Use environment variables and provide.env.example files instead.
Include a README with setup instructions, dependencies, and usage examples. Make it easy for others to understand and run your code.
Match the sharing method to your use case. Use real-time editors for collaboration, GitHub for projects, and snippets for quick examples.
