eslint/no-useless-catch Correctness

✅ This rule is turned on by default.

What it does

Disallow unnecessary catch clauses

Why is this bad?

A catch clause that only rethrows the original error is redundant, and has no effect on the runtime behavior of the program. These redundant clauses can be a source of confusion and code bloat, so it’s better to disallow these unnecessary catch clauses.

Example

try {
  doSomethingThatMightThrow();
} catch (e) {
  throw e;
}

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

oxlint --deny no-useless-catch

Config (.oxlintrc.json)

{
  "rules": {
    "no-useless-catch": "error"
  }
