有没有办法将 typescript 编译成 es6 但强制它使用 requirejs？

Question

I am writing a NodeJS typescript project. Let's say I have the following file:

class MyArray extends Array {
   myCustomMethod() { /* do something */ }
}

However, when I do

let myarray = new MyArray();

myarray.myCustomMethod();

I see

TypeError: myarray.myCustomMethod is not a function

So, I tried to change the typescript module to es6 (so that it will keep the class extends syntax), but then it uses the import and export keyword, and NodeJS doesn't support that natively.

Is there a way to force the typescript compiler to use requirejs but also use es6?

Or is it my bad and I am missing something?

TypeScript's --module option (also -m ) lets you specify what module system it should output for. "CommonJS" is the variant that uses require . Details in the project configuration options documentation .

So for instance, in tsconfig.json , "module": "CommonJS" combined with "target": "ES2015" (or "ES2020" or "ESNext" , etc.) should output code using require and also class syntax.
