What's the return type of a dynamic import?
You need to use an import type and TypeScript 2.9 or higher. Here is an example:
my_module.ts
export const user = { name: "John", age: 30 };
export const event = { name: "Birthday", date: new Date(1989, 13, 2) };
demo.ts
type ModuleType = typeof import("./my_module"); // This is the import type!
export function load(): Promise<ModuleType> {
// ...
return import("./my_module");
}
(async () => {
const module = await load();
console.log(module.user.age); // It works!
})();
tsconfig.json (Added for reference)
