Is it possible to add tooltip hints for common *.conf.js?

[Deilan]

Is it possible to add tooltip hints for common *.conf.js in a similar fashion it is done for package.json tsconfig.json, etc.? For example, karma.conf.js, protractor.confg.js, etc. I understand that it's not a regular json file, but such a capability would greatly help.

Related to #24270 which tracks this for webpack config files. In some cases, you may be able to use jsdocs to get better intellisense:

import { Configuration } from 'webpack'

/**
 * @type {Configuration}
 */
const config = {
    
};

module.exports = config

However this TypeScript bug prevents the typings from being very useful

Closing this due to lack of further community interest over the past few years.

You should now be able to use JSDoc type annotations in most cases (the linked TS issue above has been fixed for a long time). Adding a jsdoc type will get you better intellisense and optional type checking as well
