在进行了一些研究之后，包括读取字体的5和angular，文档等。

  ], (...)

在研究期间，我了解我需要指定我需要使用的(图标(，如bellow：

import {faChevronLeft, faChevronRight} from '@fortawesome/fontawesome-free-solid';
import fontawesome from '@fortawesome/fontawesome';

然后，我需要将这些图标传递给Fontawesome对象：

fontawesome.library.add(faChevronLeft, faChevronRight);

最后，我发现了(在字体上令人陶醉的文档中，我需要对i2svg方法的呼吁，该方法负责使魔术发生：

fontawesome.dom.i2svg();

文档说我必须在没有参数的情况下调用该方法。但是编译器将我指向了我必须告知以下数据的另一个方向：

export interface DOM {
  i2svg(params: { node: Node; callback: () => void }): void;
  css(): string;
  insertCss(): string;
}

到目前为止，我获得的最大值是Font-Awesome制作的浏览器中的登录，并在此代码之后使用以下信息" fontawesome.i2svg(("

fontawesome.dom.i2svg({ node: document.body, callback: callbacki2Svr });
function callbacki2Svr() { }

我已经尝试了很多(null导致" untured typeError：无法读取属性'querySelectorall'null'的属性"(，现在我无法提前。有人有建议吗？

安装：

1(遵循使用节点JS的说明([token]是我从购买中收到的密钥(：

 npm i --save @fortawesome/fontawesome
 npm config set @fortawesome:registry https://npm.fontawesome.com/[TOKEN]
 Created a .npmrc file in the root of my project with the following content:
 @fortawesome:registry=https://npm.fontawesome.com/[TOKEN]
 npm i --save @fortawesome/fontawesome-pro-light

2(更新Angular-CLI3(使用(ng b -aot(重建应用程序4(开始项目。

预先感谢您！

我们正在制作官方的角度组件(现在是在释放前(

但是， @daniel-santana告诉我们，这是不可能集成到其大型应用中的。

所以我可以给您的最佳建议是不要使用JS方法使用SVG。它使用高级功能，例如RequestAnimationFrame和MutationObservers，它们在Angular上的表现不佳。如果您无法重构应用程序使用新的SVG格式(它是新的字体Awesome 5(，则请使用Web字体。版本5的Web字体像版本4中的Web字体一样工作。升级到5的升级将涉及更改已重命名的任何图标的名称。我们在这里有详细的文档。
