Support finding a `jsconfig.json` with `tsc -p .`

jsconfig project

Suggestion

When I run tsc -p . on a JavaScript project with jsconfig.json and // @ts-check with JSDoc it complains about not finding a tsconfig.json

Currently I have to run tsc -p jsconfig.json --maxNodeModuleJsDepth 0 to check my JavaScript project.

~/projects/sync-wait-group on master*
$ tsc -p .
error TS5057: Cannot find a tsconfig.json file at the specified directory: '.'.

It tells me that tsconfig.json does not exist.

Adding detection for jsconfig.json and turning --maxNodeModuleJsDepth 0 on by default ( which we do for tsconfig.json but not jsconfig.json ) would be a good user experience improvmenent.

Use Cases

Being able to use the tsc cli on a JavaScript + JSDoc project.

Examples

tsc -p . will "just work" for a JavaScript project.

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.

まず、jsconfig.json と JSDoc を含む // @ts-check がある JavaScript プロジェクトで、報告された tsc -p . の動作を再現します。tsc CLI がプロジェクト構成をどのように解決し、maxNodeModuleJsDepth を適用するかを追跡します。tsc -p . が jsconfig.json を検出し、明示的なフラグを必要とせずに意図したデフォルト値を使用すれば完了です。
