ESLint

Raycast makes it easy to lint your extensions using the CLI's lint command (ray lint).

Raycast provides by default an opinionated ESLint configuration that includes everything you need to lint your Raycast extensions. The default configuration is as simple as this:

import { defineConfig } from "eslint/config";
import raycastConfig from "@raycast/eslint-config";

export default defineConfig([...raycastConfig]);

It abstracts away the different ESLint dependencies used for Raycast extensions and includes different rule-sets.

It also includes Raycast's own ESLint plugin rule-set that makes it easier for you to follow best practices when building extension. For example, there's a rule helping you follow the Title Case convention for Action components.

You can check Raycast's ESLint plugin rules directly on the repository documentation.

Customization

You're free to turn on/off rules or add new plugins as you see fit for your extensions. For example, you could add the rule @raycast/prefer-placeholders for your extension:

import { defineConfig } from "eslint/config";
import raycastConfig from "@raycast/eslint-config";

export default defineConfig([
  ...raycastConfig,
  {
    rules: {
      "@raycast/prefer-placeholders": "warn",
    },
  },
]);

To keep the consistency of development experiences across extensions, we don't encourage adding too many personal ESLint preferences to an extension.

Migration

Starting with version 1.48.8, the ESLint configuration is included automatically when creating a new extension using the Create Extension command. If your extension was created before this version, you can migrate following the steps outlined on the v1.48.8 page.
