如何添加引导到一个angular-cli项目

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).

使用angular-cli和css的工作示例:

1.安装引导

NPM安装bootstrap tether jquery——保存

2.添加到.angular-cli.json

  "styles": [
    "../node_modules/bootstrap/dist/css/bootstrap.css"
  ],
  "scripts": [
    "../node_modules/jquery/dist/jquery.js",
    "../node_modules/tether/dist/js/tether.js",
    "../node_modules/bootstrap/dist/js/bootstrap.js"
  ],

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"
],

步骤1: NPM安装bootstrap@latest——save-dev 这将安装最新版本的引导程序，但是，可以通过添加版本号来安装指定的版本

打开styles.css并添加以下内容 @ import " ~引导/ dist / css / bootstrap.css”

Install bootstrap using npm i --save bootstrap@version.Now,go to nodemodules folder and from bootstrap folder copy the path of 'bootstrap.min.css.js' and paste the full path(like nodemodules/bootstrap/css/bootstrap.min.css.js) in angular.json under script tag file and re-run the server and to check whether the installation is successful run the program in any browser you like and press F12 you'll find a part of the window gets opened,now go to elements tab open head tag and if you see bootstrap in style tag,then your installation is successful.

在bash中运行npm install ng2-bootstrap bootstrap——save 在angular-cli.json中添加/更改以下内容 “风格”:( “. . / node_modules /引导/ dist / css / bootstrap.min.css” ), “脚本”:( “. . / node_modules / jquery / dist / jquery.min.js”, “. . / node_modules /引导/ dist / js / bootstrap.min.js” ),

将此添加到styles.css文件中

@import "~bootstrap/dist/css/bootstrap.css";
