Contributing

Open an issue on GitHub. For bugs, include the app version, your operating system, the connection type (AWS, SSO, Assume Role or local endpoint) and the exact message you saw. Never paste credentials or real table data.

• Fork the repository, create a branch and keep each pull request focused on one change.
• Run npm test and npm run lint before opening it; both must pass.
• Describe what changed and how you verified it, with a screenshot for UI changes.
• By contributing you agree that your code is distributed under the project’s license.

• Controllers do not catch errors: they throw, and the central error handler maps AWS errors to HTTP responses.
• Every value interpolated into HTML goes through escapeHtml. Data from DynamoDB is untrusted.
• Table calls use tableApi(...) so they carry the active tab’s connection.
• localStorage is only accessed through utils/storage.js.
• A new code-generator language is a new module in public/js/codegen/languages/, registered in its index.js, with user values encoded through codegen/expressions.js.
