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>
更新v1.0.0-beta.26
你可以在文档中看到导入引导的新方法
如果仍然不工作,使用ng serve命令重新启动
1.0.0或以下版本:
在index.html文件中,你只需要引导css链接(不需要js脚本)
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">
And
npm install ng2-bootstrap --save
npm install moment --save
在my_project/src/system-config中安装ng2-bootstrap后。ts:
/** Map relative paths to URLs. */
const map: any = {
'moment': 'vendor/moment/moment.js',
'ng2-bootstrap': 'vendor/ng2-bootstrap'
};
/** User packages configuration. */
const packages: any = {
'ng2-bootstrap': {
defaultExtension: 'js'
},
'moment':{
format: 'cjs'
}
};
在my_project/angular-cli-build.js中:
module.exports = function (defaults) {
return new Angular2App(defaults, {
vendorNpmFiles: [
'ng2-bootstrap/**/*',
'moment/moment.js'
]
});
};
不要忘记这个命令
把你的模块放到供应商中:
ng build
从另一个模块导入相同的原理。
