在打字稿中创建扩展类

Question

正在尝试为我们的代码库中广泛使用的遥测库创建扩展类。

在下面的沙箱中模拟了我创建扩展的方式。 Logger

Crux是，我们有一个库tat，它为我们提供了一个单例记录器。

//centralized client governed outside or project - but inheritance/overriding is possible,
class singletonClient {


   // this method's consumption is widespread, as a new param is introduced,lot of code changes required.
   // public log(some: string) {
      public log(some: string, extensionParams: any) {
        // is there any cleaner way to pass the param from the context object from context class? (like decorator or something)
        console.log(some, extensionParams);
      }
    }
    //singleton client used throughout the project - govered outside our project
    const _client = new singletonClient();

我的要求是向库中添加扩展，并且正在寻找最优雅/更干净的方法（可能是装饰器或闭包可能会有所帮助，但我对TS的了解非常有限）

我要上的课是

   class context {
      public extensionParams: any;
      public cli: singletonClient;
      constructor(name: string) {
        this.extensionParams = { name: name };
        this.cli = _client;
      }
    }

    // const _context = new context("Product A");
    const _context1 = new context("Product B");
    const _context2 = new context("Product C");

    //This change is difficult to make
    _client.log("entry", _context1.extensionParams);
    _client.log("entry", _context2.extensionParams);

    //This is easier => coz only one line change in the start of the js file.
    //_context1.cli.log("entry"); // but how to pass in the extension params without modifying the signatures
