A practical approach to working with JSON
A short guide to readable JSON, useful validation, and safer data handling in everyday development.
Keep data readable
Consistent indentation makes nested data easier to review in code reviews and logs. Choose a format your team can scan quickly.
When a payload is large, focus on the shape first: identify the fields, types, and nesting before investigating individual values.
Validate at boundaries
Treat data from requests, files, and external services as untrusted. Parse it and validate the shape where it enters your application.
Useful validation errors explain what was expected and where the input differs. Avoid logging sensitive payloads while diagnosing issues.
