typedef imports should use default exports

Search Terms

checkJs typedef import

Suggestion

When the module ./core.controller has a default export defined, I would like to be able to do:

/**
 * @typedef { import("./core.controller") } Chart
 */

Instead of:

/**
 * @typedef { import("./core.controller").Chart } Chart
 */

Use Cases

My file had defined export default Chart;.

TypeScript made me add a duplicate export, which I don't want to have to add

export {
	Chart
};

This resulted in lots of extra code

It also took me an extremely long amount of time to figure out I needed to do this because the documentation did not mention this as a limitation.

Examples

Already shared in the above sections.

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

TypeScript ハンドブックの import types セクションと、issue に示されている既存の JSDoc typedef import forms から始めます。default-exported module がどのように表現され、テストされているかを追跡し、そのうえで、重複した named export を必要とせずに短い import form が受け入れられること、およびドキュメントがその動作を説明していることを確認します。
