我使用了一个Angular 4项目@angular/cli,在开发模式下运行应用程序时,我在控制台中收到了这些警告:
zone.js:1489 [Violation] 'setTimeout' handler took 209ms
2[Violation] Added non-passive event listener to a scroll-blocking 'mousewheel' event. Consider marking event handler as 'passive' to make the page more responsive.
zone.js:1157 [Violation] Added non-passive event listener to a scroll-blocking 'touchstart' event. Consider marking event handler as 'passive' to make the page more responsive.

2zone.js:1157 [Violation] …我正在 Angular-cli 项目中创建传单地图。地图图块本地存储在“资产”文件夹中，因为它是栅格地图。问题是当我有很多缩放级别的地图时，我有超过 28 万张图像，大小大约为 1.1 GB，而且它会变得更大。
当我ng serve在这里使用时是控制台输出（它被卡住了@assets optimization）：
** NG Live Development Server is running on http://localhost:4200. **
