Angular6 引入 adminLTE2.4.8，adminLTE 代码拆分成组件，超级简约版

1： 引入 adminlte

      npm install admin-lte --save

2： 此时，在node_modules  文件夹下生成  admin-lte文件夹，内容如下，

3： 在集成 admin-lte 的时候，已经自动帮我们把 bootstrap  ，  jquery 等集成了（可以在node_modules\admin-lte\bower_components 下查看，或 node_modules\admin-lte\plugins ， 也可以在 node_modules 下查看）， 不需要另行npm install

4：在angular.json中引入需要的 css ， 或者 js ,或者less

  "styles": [
              "node_modules/bootstrap/dist/css/bootstrap.css",
              "node_modules/font-awesome/css/font-awesome.css",
              "node_modules/ionicons/dist/css/ionicons.css",
              "src/_variables.less",
              "src/styles.css"
            ],
            "scripts": [
              "node_modules/jquery/dist/jquery.js",
              "node_modules/admin-lte/plugins/jQueryUI/jquery-ui.js",
              "node_modules/bootstrap/dist/js/bootstrap.js",
              "node_modules/admin-lte/dist/js/adminlte.js",
              "src/assets/js/adminLTEOptions.js",
              "src/assets/js/scripts.js"
            ]

5： 记得把  _variables.less   文件新建在src 目录下

@import "../node_modules/admin-lte/build/less/AdminLTE";
@import "../node_modules/admin-lte/build/less/skins/_all-skins";
@boxed-layout-bg-image-path: "/assets/img/boxed-bg.jpg";

6： 在  assets 文件下 新建 js 文件夹

7： adminLTEOptions.js 可以去官网上下载，也可以参考如下

var AdminLTEOptions = {
  //Add slimscroll to navbar menus
  navbarMenuSlimscroll: true,
  navbarMenuSlimscrollWidth: "3px", //The width of the scroll bar
  navbarMenuHeight: "200px", //The height of the inner menu
  //General animation speed for JS animated elements such as box collapse/expand and
  //sidebar treeview slide up/down. This options accepts an integer as milliseconds,
  //'fast', 'normal', or 'slow'
  animationSpeed: 500,
  //Sidebar push menu toggle button selector
  sidebarToggleSelector: "[data-toggle='offcanvas']",
  //Activate sidebar push menu
  sidebarPushMenu: true,
  //Activate sidebar slimscroll if the fixed layout is set (requires SlimScroll Plugin)
  sidebarSlimScroll: true,
  //Enable sidebar expand on hover effect for sidebar mini
  //This option is forced to true if both the fixed layout and sidebar mini
  //are used together
  sidebarExpandOnHover: true,
  //BoxRefresh Plugin
  enableBoxRefresh: true,
  //Bootstrap.js tooltip
  enableBSToppltip: true,
  BSTooltipSelector: "[data-toggle='tooltip']",
  //Enable Fast Click. Fastclick.js creates a more
  //native touch experience with touch devices. If you
  //choose to enable the plugin, make sure you load the script
  //before AdminLTE's app.js
  enableFastclick: false,
  //Control Sidebar Tree views
  enableControlTreeView: true,
  //Control Sidebar Options
  enableControlSidebar: true,
  controlSidebarOptions: {
    //Which button should trigger the open/close event
    toggleBtnSelector: "[data-toggle='control-sidebar']",
    //The sidebar selector
    selector: ".control-sidebar",
    //Enable slide over content
    slide: true
  },
  //Box Widget Plugin. Enable this plugin
  //to allow boxes to be collapsed and/or removed
  enableBoxWidget: true,
  //Box Widget plugin options
  boxWidgetOptions: {
    boxWidgetIcons: {
      //Collapse icon
      collapse: 'fa-minus',
      //Open icon
      open: 'fa-plus',
      //Remove icon
      remove: 'fa-times'
    },
    boxWidgetSelectors: {
      //Remove button selector
      remove: '[data-widget="remove"]',
      //Collapse button selector
      collapse: '[data-widget="collapse"]'
    }
  },
  //Direct Chat plugin options
  directChat: {
    //Enable direct chat by default
    enable: true,
    //The button to open and close the chat contacts pane
    contactToggleSelector: '[data-widget="chat-pane-toggle"]'
  },
  //Define the set of colors to use globally around the website
  colors: {
    lightBlue: "#3c8dbc",
    red: "#f56954",
    green: "#00a65a",
    aqua: "#00c0ef",
    yellow: "#f39c12",
    blue: "#0073b7",
    navy: "#001F3F",
    teal: "#39CCCC",
    olive: "#3D9970",
    lime: "#01FF70",
    orange: "#FF851B",
    fuchsia: "#F012BE",
    purple: "#8E24AA",
    maroon: "#D81B60",
    black: "#222222",
    gray: "#d2d6de"
  },
  //The standard screen sizes that bootstrap uses.
  //If you change these in the variables.less file, change
  //them here too.
  screenSizes: {
    xs: 480,
    sm: 768,
    md: 992,
    lg: 1200
  }
};

8： scripts.js 如下

$.widget.bridge('uibutton', $.ui.button);

//receive calls from typescript code to update the layouts
var AdminLTE = (function() {
  return {
    init: function() {
      $(function(){
        $.AdminLTE.layout.activate();
        $.AdminLTE.layout.fix();
        $.AdminLTE.layout.fixSidebar();
      });
    }
  }
})(AdminLTE||{});

9：  新建结构目录

11：app.component.html 如下

12：app.component.ts 如下

import {Component, OnChanges, OnInit} from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements  OnInit {
  bodyClasses = 'skin-blue sidebar-mini';
  body: HTMLBodyElement = document.getElementsByTagName('body')[0];
  title = 'angularstart7';
  ngOnInit() {
    this.body.classList.add('skin-blue');
    this.body.classList.add('sidebar-mini');
  }
}

10： 运行结果如下     如果发现 点击menu 按钮没有效果  ，或者所有的点击都没效果，请核对下使用的版本，

     adminlte.2.4.8   版本和 2.3版本 class 类差异有些大   ，  所以请去官网  使用想对应的  html 类
