Question

经过一些研究，包括阅读Font Awesome 5 with Angular，documentation等，我无法在Angular 5 App和Font-Awesome 5（Pro）之间进行整合。

问题：图标不会显示。

角cli.json

    (...)
    "scripts": [
    "../node_modules/jquery/dist/jquery.min.js",
    "../node_modules/popper.js/dist/umd/popper.js",

    "../node_modules/summernote/dist/summernote.min.js",
    "../node_modules/@fortawesome/fontawesome/index.js (tried with and without this file)"
  ], (...)

在我的研究期间，我了解我需要指定我需要使用的（图标），如下所示：

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（在font-awesome documentation中我需要调用负责使魔法发生的i2svg方法：

fontawesome.dom.i2svg();

文档说我必须在没有参数的情况下调用该方法。但编译器指向另一个方向，我必须告知以下数据：

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

到目前为止我实现的最大值是通过font-awesome使用以下信息在浏览器中登录＆＃34; fontawesome.dom.i2svg（）＆＃34;在这段代码之后：

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

function callbacki2Svr() { }

我已经尝试了很多（null结果＆＃34; Uncaught TypeError：无法读取属性＆＃39; querySelectorAll＆＃39; null＆＃34;）现在我无法前进。有人有建议吗？

安装：

1）按照use node js上的说明操作（[TOKEN]是我从购买时收到的钥匙）：

 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）更新了角度cli 3）使用（ng b -aot）重建应用程序 4）启动了项目。

提前谢谢！

HTML代码示例 登录页面（没有＆＃34;我＆＃34;标记）

<div class="login-page">
  <div class="wrapper-login">
    <img src="assets/image/logo/horizontal-bew.svg" />
    <raptor-textbox #txtUser type="text" iconClass="fa fa-user-o" iconPosition="right" placeholder="Login"
                [(value)]="userName" (onKeyUp)="updateUserName($event)" (onEnterPressed)="userKeyEnter()"></raptor-textbox>
    <raptor-textbox #txtPwd type="password" iconClass="fa fa-key" iconPosition="right" placeholder="Senha"
                [value]="pwd" (onKeyUp)="updatePwd($event)" (onEnterPressed)="pwdKeyEnter()"></raptor-textbox>
     <raptor-button cssClass="btn btn-light btn-block" text="Entrar" (click)="authenticate()"></raptor-button>
     <a [attr.href]="'#loginModal'" data-toggle="modal" [attr.data-target]="'#loginModal'">Forgot Password</a>
  </div>
</div>

<raptor-modal title="Forgot Password"
          icon="fa fa-envelope-o"
          cssClass="fade"
          classModal="modal-dialog modal-dialog-centered"
          modalId="loginModal"
          (onSavedClicked)="saveForm($event)"
          (onCancelClicked)="cancelModal($event)">

  <div class="row">
    <div class="form-group col-12">
      <label>Email</label>
      <raptor-textbox type="email" typeValue="email" applyValidation="true" applyMask="true" icon="fa fa-envelope" iconPosition="right" placeholder="E-mail..."></raptor-textbox>
    </div>
  </div>
</raptor-modal>

猛禽按钮（使用＆＃34; i＆＃34;标记）

<button type="button" [class]="cssClass" (click)="click()" [attr.data-target]="dataTarget" [attr.disabled]="isDisabled ?'' : null">
  <i *ngIf="hasIcon()" class="{{ icon }}"></i><span>{{ text }}</span>
</button>

/**
* verify if icon was defined
* @hasIcon
*
*/
public hasIcon() {
  return this.icon && this.icon.length > 0;
}

我们正在开发一个官方Angular组件（现在正在预发布中）https://github.com/FortAwesome/angular-fontawesome

然而，@ daniel-santana告诉我们，这不可能集成到他们的大型应用程序中。

所以我能给你的最好建议是不要将SVG与JS方法一起使用。它使用了诸如requestAnimationFrame和MutationObservers之类的高级功能，这些功能与Angular不兼容。如果您无法重构您的应用程序以使用新的SVG格式（这是Font Awesome 5中的新增功能），请坚持使用Web Fonts。版本5的Web字体与版本4中的Web字体一样工作。升级到5将涉及更改已重命名的任何图标的名称。我们详细介绍了docs here。
