DX of Error Messages
summary
Claim: cryptic errors drive developers away and clear, actionable messages increase API loyalty. Compares a worthless return 2 error to explicit text like "missing required parameters: name, email" and shows production examples — Square Payments returning line_items[0].name required and Google Maps returning rich API key errors with guidance and links. Recommends error payloads that name the field, show the index for arrays, include a one-line next step and a documentation URL.
