如何忽略打字稿中的导入语句

Question

log.ts has the following code

import {LOG} from './log'

LOG.e("tag","error");
LOG.f("tag","error");
LOG.d("tag","error");

I want the IntelliSense support for the TS file but don't want the consequences of import on generated javascript.

I simply want the following in my Javascript file (log.js)

    LOG.e("tag","error");
    LOG.f("tag","error");
    LOG.d("tag","error");

Answer 1

log.ts file must contain only declarations.

declare class LOG {
  public static e(a: string, b: string): void;
  public static f(a: string, b: string): void;
  public static d(a: string, b: string): void;
}

If you want to use an imported class, and it should not be included in the generated javascript, then you need to declare it using declare .

This class is not functional javascript code, but only declares the type of the class and its methods. When generating javascript, this class will not be included in the build.

But to execute such javascript, LOG must already be declared in the global environment.
