OpenAPI / Swagger tips

📡

The OpenAPI spec supports both YAML and JSON. YAML is preferred for hand-written specs (more readable); JSON is preferred for programmatic generation.

💡

Many code generators (e.g., openapi-generator-cli) accept both formats. Convert if your CI requires one specific format for consistency.

🔍

Swagger Hub and SwaggerUI render both formats identically. Conversion is useful when sharing specs with teams that have different format preferences.

🧰

Use the conversion to validate spec structure — YAML can hide schema issues that become obvious in JSON's explicit braces and quoted strings.
