### ✅ Viability Checklist

- [x] This wouldn't be a breaking change in existing TypeScript/JavaScript code
- [x] This wouldn't change the runtime behavior of existing JavaScript code
- [x] This could be implemented without emitting different JS based on the types of the expressions
- [x] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
- [x] This isn't a request to add a new utility type: https://github.com/microsoft/TypeScript/wiki/No-New-Utility-Types
- [x] This feature would agree with the rest of our Design Goals: https://github.com/Microsoft/TypeScript/wiki/TypeScript-Design-Goals

### ⭐ Suggestion

Add an option to enforce imports with file extension when the module is iESM (type: module) and moduleResolution is bundler.

### 📃 Motivating Example

For now in bundler moduleResolution, typescript is tolerent.
But when we develop a library, we have no idea of the strictness of the bundler (webpack is strict for example).
We need a way to enforce the imports with file extension in case the module is ESM

A dedicated option in the tsconfig can resolve it that we will enable or not

### 💻 Use Cases

1. What do you want to use this for?
2. What shortcomings exist with current approaches?
3. What workarounds are you using in the meantime?

まず、コンパイラの moduleResolution bundler の動作と、ESM (type: module) import の処理を確認します。提案する tsconfig オプションが既存の動作を変更せずにファイル拡張子を強制する方法を定義し、その後、strict 構成と non-strict 構成の両方のカバレッジを追加します。完了の定義は、オプションが有効な場合に bundler resolution が拡張子のない ESM import を報告することです。
