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).
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://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js" integrity="sha384-OgVRvuATP1z7JjHLkuOU7Xw704+h835Lr+6QL9UvYjZE3Ipu6Tp75j7Bh/kR0JKI" 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>
我猜上面的方法在发布后已经改变了，看看这个链接
https://github.com/valor-software/ng2-bootstrap/blob/development/docs/getting-started/ng-cli.md
启动项目
npm i -g angular-cli
ng new my-app
cd my-app
ng serve
npm install --save @ng-bootstrap/ng-bootstrap
安装ng-bootstrap和bootstrap
npm install ng2-bootstrap bootstrap --save
src / app / app.module开放。Ts和add
import { AlertModule } from 'ng2-bootstrap/ng2-bootstrap';
...
@NgModule({
...
imports: [AlertModule, ... ],
...
})
angular-cli开放。并在样式数组中插入一个新条目
"styles": [
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.min.css"
],
打开src/app/app.component.html并通过添加测试所有工作
<alert type="success">hello</alert>
做以下几点:
npm i bootstrap@next --save
这将为您的项目添加引导4。
接下来进入src/style。SCSS或src/style.css文件(选择你正在使用的任何一个)并导入bootstrap:
对于style.css
/* You can add global styles to this file, and also import other style files */
@import "../node_modules/bootstrap/dist/css/bootstrap.min.css";
对于style.scss
/* You can add global styles to this file, and also import other style files */
@import "../node_modules/bootstrap/scss/bootstrap";
对于脚本，你仍然需要在angular-cli中添加文件。在Angular版本6中，这个编辑需要在Angular .json文件中完成:
"scripts": [
"../node_modules/jquery/dist/jquery.js",
"../node_modules/tether/dist/js/tether.js",
"../node_modules/bootstrap/dist/js/bootstrap.js"
],
