Disallow async functions which have no `await` expression (require-await)

Async functions which have no await expression may be the unintentional result of refactoring.

Rule Details

This rule warns async functions which have no await expression.

Examples of incorrect code for this rule:

/*eslint require-await: "error"*/

async function foo() {
    doSomething();
}

bar(async () => {
    doSomething();
});

Examples of correct code for this rule:

/*eslint require-await: "error"*/

async function foo() {
    await doSomething();
}

bar(async () => {
    await doSomething();
});

function foo() {
    doSomething();
}

bar(() => {
    doSomething();
});

// Allow empty functions.
async function noop() {}

When Not To Use It

If you don't want to notify async functions which have no await expression, then it's safe to disable this rule.

require-yield

Version

This rule was introduced in ESLint 3.11.0.
