allowNonTsExtensions

Suggestion

Make allowNonTsExtensions from
https://github.com/Microsoft/TypeScript/blob/0010a38660b1eb03c188c9c1758177b4501760b7/src/compiler/types.ts#L4480
public / not-internal

Use Cases

The Monaco Editor requires usage of this compiler option for in-memory TypeScript / JavaScript editors.

Examples

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.

Beginne mit allowNonTsExtensions in src/compiler/types.ts an der referenzierten Deklaration und vergleiche anschließend, wie das Monaco Editor-Beispiel die Option verwendet. Mache die Option wie angefordert öffentlich verfügbar und verifiziere, dass die öffentliche Compiler-API sie für den Anwendungsfall des In-Memory-Editors bereitstellt.
