• This is a crash

💻 Code

My tsconfig.json:

{
  "compilerOptions": {
    "module": "commonjs",
    "importHelpers": true,
    "declaration": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es2020",
    "sourceMap": true,
    "outDir": "./dist",
    "baseUrl": "./",
    "incremental": true,
    "skipLibCheck": true,
    "strict": true,
    "moduleResolution": "Node"
  }
}

Minimal reproducing code:

import {Color} from '../entities';
class Foo {
   d3color = import('d3-color');
}

🙁 Actual behavior

It's transpiled as:

const entities_1 = require("../entities");

class Foo {
    constructor() {
        this.d3color = Promise.resolve().then(() => require('d3-color'));
    }
    foo(): Color {
       throw new Error()
    }
}

🙂 Expected behavior

It's transpiled as:

const entities_1 = require("../entities");
class Foo {
    constructor() {
        this.d3color = import('d3-color');
    }
}

I want at least opt-in for dynamic imports.

Workaround

It won't work for relative path modules.

import type * as d3color from 'd3-color';
const nativeImport = Function('mod', `return import(mod)`);
const d3color: typeof d3color = await nativeImport('d3-color');

Looks like duplicate of #45125 which is about PR #44501

@IllusionMH You are right, I'm closing issue.
