#Configuration

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

export default defineConfig([
  promisePlugin.configs.recommended,

    rules: {
      'promise/no-new-statics': 'error',
    },
  },
]);

Disallow calling new on a Promise static method.

#Rule Details

Promise static methods (resolve, reject, all, allSettled, any, race, withResolvers) return Promises directly — they are not constructors. Calling new on them is almost always a mistake and produces unexpected behavior.

Examples of incorrect code for this rule:

new Promise.resolve(value);
new Promise.reject(reason);
new Promise.all([p1, p2]);
new Promise.allSettled([p1, p2]);
new Promise.any([p1, p2]);
new Promise.race([p1, p2]);
new Promise.withResolvers();

Examples of correct code for this rule:

Promise.resolve(value);
Promise.reject(reason);
Promise.all([p1, p2]);
new Promise(function (resolve, reject) {});
new SomeClass.resolve();

#Autofix

This rule provides an autofix that removes the new keyword.

#Differences from ESLint

• new (Promise as any).resolve() and similar TS type-assertion or non-null-assertion wrappers around Promise are not flagged. Under @typescript-eslint/parser, type wrappers are stripped before the rule sees the AST, so ESLint would flag these. rslint preserves the TS node structure and only unwraps parentheses.
