我们想在angular-cli 1.0.0-beta.5生成的应用程序中使用bootstrap 4 (4.0.0-alpha.2)(w/ node v6.1.0)。
在获得bootstrap及其对npm的依赖之后，我们的第一个方法是将它们添加到angular-cli-build.js中:
'bootstrap/dist/**/*.min.+(js|css)',
'jquery/dist/jquery.min.+(js|map)',
'tether/dist/**/*.min.+(js|css)',
然后导入到index。html中
<script src="vendor/jquery/dist/jquery.min.js"></script>
<script src="vendor/tether/dist/js/tether.min.js"></script>
<link rel="stylesheet" type="text/css" href="vendor/bootstrap/dist/css/bootstrap.min.css">
<script src="vendor/bootstrap/dist/js/bootstrap.min.js"></script>
这在ng serve中工作得很好，但当我们生成一个带有-prod标志的构建时，dist/vendor中的所有依赖项都消失了(惊讶!)
我们打算如何处理这样的场景(即加载引导脚本)在一个用angular-cli生成的项目?
我们有以下想法，但我们真的不知道该怎么做……
use a CDN ? but we would rather serve these files to guarantee that they will be available
copy dependencies to dist/vendor after our ng build -prod ? But that seems like something angular-cli should provide since it 'takes care' of the build part ?
adding jquery, bootstrap and tether in src/system-config.ts and somehow pull them into our bundle in main.ts ? But that seemed wrong considering that we are not going to explicitly use them in our application's code (unlike moment.js or something like lodash, for example).
现在有了新的ng-bootstrap 1.0.0-beta。5版本支持大多数基于Bootstrap的标记和CSS的原生Angular指令。
使用它所需的唯一依赖项是引导。不需要使用jquery和popper.js依赖。
ng-bootstrap是完全取代JavaScript实现的组件。所以你不需要在.angular-cli.json的scripts部分中包含bootstrap.min.js。
当你在angular-cli的最新版本中集成bootstrap和生成的项目时，请遵循以下步骤。
Inculde bootstrap.min.css in your .angular-cli.json, styles section.
"styles": [
"styles.scss",
"../node_modules/bootstrap/dist/css/bootstrap.min.css"
],
Install ng-bootstrap dependency.
npm install --save @ng-bootstrap/ng-bootstrap
Add this to your main module class.
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
Include the following in your main module imports section.
@NgModule({
imports: [NgbModule.forRoot(), ...],
})
Do the following also in your sub module(s) if you are going to use ng-bootstrap components inside those module classes.
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
imports: [NgbModule, ...],
})
Now your project is ready to use available ng-bootstrap components.
对于bootstrap 4.5, angular 10
npm install bootstrap --save
更新你的风格。这样的SCSS带有bootstrap import语句。
$theme-colors: (
"primary": #b867c6,
"secondary": #f3e5f5,
"success": #388e3c,
"info": #00acc1,
"light": #f3e5f5,
"dark": #863895
);
@import "~bootstrap";
@import url('https://fonts.googleapis.com/css2?family=Raleway&display=swap');
body {
color: gray('800');
background-color: theme-color('light');
font-family: 'Raleway', sans-serif;
}
导入引导应该在变量覆盖之后。[这个例子还展示了如何放置自己的主题颜色。]
我发现很多解决方案在新版本的Angular-CLI中不再适用了。
您可以尝试在app.component.html的顶部添加以下链接标记，并在底部添加脚本标记。
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous">

<script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script>

但是如果你想使用ngx-bootstrap，那么在你的项目目录下运行下面的命令
ng add ngx-bootstrap
使用以下内容作为app.component.html的内容进行测试
<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>
