Configuration tips

⚙️

Different frameworks prefer different formats — Rails uses YAML, .NET uses JSON, Node.js apps are split. Convert configs when moving between ecosystems.

💡

Spring Boot reads YAML and JSON interchangeably from application.yml or application.json. Convert if you prefer one format for your team.

🔍

When sharing config snippets in documentation, YAML is more readable for humans; JSON is universal for examples that need to be valid JavaScript.

📝

Comments are YAML-only. When converting JSON → YAML, you can add comments by hand afterward. YAML → JSON will strip comments (JSON has no comment syntax).
