no-log-only-catch

eslint:no-log-only-catch

Disallow `catch` clauses that only log (or silently do nothing) and then swallow the error; rethrow or handle it instead.

Default: error
Fix: none
Languages: typescript

Why

Swallowing an exception after logging lets execution continue as if the operation succeeded.

Fix

Rethrow the error, return an explicit fallback, or perform concrete recovery.

Before / after

Executed by this rule’s unit tests.

Before

Do not only log a failure

src/task.ts · focus

try { run(); } catch (error) { console.error(error); }

After

Preserve failure after logging

src/task.ts · focus

try { run(); } catch (error) { console.error(error); throw error; }

Limits

Documented intentional ignores, tests, and catches with observable recovery are excluded.
