require-await

Disallow async functions which have no await expression.

✅

Extending "plugin:@typescript-eslint/recommended-type-checked" in an ESLint configuration enables this rule.

💭

This rule requires type information to run.

This rule extends the base eslint/require-await rule. It uses type information to add support for async functions that return a Promise.

Examples​

Examples of correct code for this rule:

async function returnsPromise1() {
  return Promise.resolve(1);
}

const returnsPromise2 = () => returnsPromise1();

How to Use​

.eslintrc.cjs
module.exports = {
  "rules": {
    // Note: you must disable the base rule as it can report incorrect errors
    "require-await": "off",
    "@typescript-eslint/require-await": "error"
  }
};
Try this rule in the playground ↗

Options​
