#no-return-wrap

#Configuration

import { defineConfig, promisePlugin } from '@rslint/core';

export default defineConfig([
  promisePlugin.configs.recommended,
  {
    rules: {
      'promise/no-return-wrap': 'error',
    },
  },
]);

Disallow wrapping values in Promise.resolve or Promise.reject when not needed.

#Rule Details

Inside a .then(), .catch(), or .finally() callback, returning a raw value already resolves the promise chain with that value, and throwing already rejects it. This rule reports callbacks that return Promise.resolve(...) or Promise.reject(...) instead of using the direct value or throw.

Examples of incorrect code for this rule:

promise.then(function (value) {
  return Promise.resolve(value * 2)
})

promise.catch(function (error) {
  return Promise.reject(error)
})

promise.then(() => Promise.resolve(42))

Examples of correct code for this rule:

promise.then(function (value) {
  return value * 2
})

promise.catch(function (error) {
  throw error
})

promise.then(() => 42)

#Options

#allowReject

Pass { "allowReject": true } to allow returning Promise.reject(...) from a promise callback. Promise.resolve(...) remains disallowed.

{ "promise/no-return-wrap": ["error", { "allowReject": true }] }

promise.catch(function (error) {
  return Promise.reject(error)
})
