Callback Error Guard Linting

A lint utility that rejects callback invocations using literals instead of error objects for configured callback identifiers.

Capabilities

Linting default callbacks

• Lints code strings and reports a violation when a callback named callback or cb receives a literal value as the first argument; passes when using null, undefined, Error instances, or variables. @test

Custom callback identifiers

• Accepts additional callback identifier names to lint and applies the same literal-rejection behavior. @test

Helpful output

• Returns lint results including the count of errors and the messages for each violation. @test

 * @param {{ callbackNames?: string[] }} [options] - Extra callback identifiers to check alongside defaults.
 * @returns {Promise<{ errorCount: number, messages: string[] }>} - Number of violations and their messages.
