no-silent-promise-catch

Disallow .catch() and second-argument .then() handlers that silently swallow a rejection; log, rethrow, or handle the error.

silentCatch Rule source Tests Catalog JSON

Why

A swallowed rejection hides failures and gives callers an indistinguishable fallback value.

Fix

Log, rethrow, or explicitly recover from the rejection; explain intentional teardown suppression.

Examples

Before — flagged Do not swallow the rejection

src/load.ts

load().catch(() => null);

After — preferred Report the rejection

src/load.ts

load().catch((error) => logger.error({ error }, "load failed"));
