promise/avoid-new Style

Disallow creating promises with new Promise().

Many cases that use new Promise() could be refactored to use an async function. async is considered more idiomatic in modern JavaScript.

Examples of incorrect code for this rule:

javascript

function foo() {
  return new Promise((resolve, reject) => {
    /* ... */
  });
}

Examples of correct code for this rule:

javascript

async function foo() {
  // ...
}
const bar = await Promise.all([baz(), bang()]);

How to use

To enable this rule using the config file or in the CLI, you can use:

Config (.oxlintrc.json)Config (oxlint.config.ts)CLI

json

{
  "plugins": ["promise"],
  "rules": {
    "promise/avoid-new": "error"
  }
}

import { defineConfig } from "oxlint";

export default defineConfig({
  plugins: ["promise"],
  rules: {
    "promise/avoid-new": "error",
  },
});

bash

oxlint --deny promise/avoid-new --promise-plugin

This rule was added in v0.6.1.
