gulp使用——将js、css引入index.html中(以wiredep为例)
wiredep是一个gulp插件，能够将js、css文件自动插入到html中。它属于inject相关插件，这一类插件的功能就是如此。gulp使用的步骤如下：
1.首先，在项目根目录下创建一个文件package.json ，内容如下：
{
"name": "demo",
"version": "0.1.0-SNAPSHOT",
"description": "spring-boot and angularJS",
"private": true,
"dependencies": {},
"devDependencies": { //项目需要依赖的前端插件(注意：拷贝进去时这段注释要删掉)
"gulp": "^3.9.0",
"gulp-util": "^3.0.7",
"gulp-cssnano": "^2.1.0",
"gulp-htmlmin": "^1.3.0",
"gulp-imagemin": "^2.4.0",
"gulp-uglify": "^1.5.1",
"gulp-filter": "^3.0.1",
"gulp-replace": "^0.5.4",
"gulp-useref": "^3.0.5",
"gulp-autoprefixer": "^3.1.0",
"gulp-ng-annotate": "^1.1.0",
"gulp-sass": "^2.1.1",
"gulp-rev": "^6.0.1",
"gulp-rev-replace": "^0.4.3",
"gulp-flatten": "^0.2.0",
"gulp-jshint": "^2.0.0",
"gulp-htmlhint": "^0.3.1",
"jshint-stylish": "^2.1.0",
"htmlhint-stylish": "^1.0.3",
"wiredep": "^3.0.0",
"browser-sync": "^2.11.1",
"del": "^2.2.0",
"http-proxy-middleware": "^0.9.1"
}
}2.其次，cmd进入项目根目录，运行命令npm install，它将把package.json中声明的依赖插件都down下来，并在项目根目录下生成文件夹node_modules,并将插件保存在其中。
3.在项目根目录下创建一个文件gulpfile.js，内容如下：
"use strict";
var gulp = require('gulp'), //将上面down下来的插件都要引入，以便需要
gutil = require('gulp-util'),
wiredep = require('wiredep').stream
gulp.task('html', function() { // 创建task任务:可以在cmd命令中执行任务
gulp.src('src/main/webapp/index.html')
.pipe(wiredep({ // 调用插件wiredep执行方法
optional: 'configuration',
goes: 'here'
}))
.pipe(gulp.dest('src/main/webapp'))
})4.接着在项目根目录下创建一个文件:.bowerrc,创建完毕后在IDE中会被隐藏。文件内容如下:
{
"directory" : "src/main/webapp/bower_components"
}显而易见，这个文件的作用是指定bower install时，下载的angularJS等插件存放的目录位置。如果没有这个文件，那么通过bower命令下载的插件将会被保存在项目根目录下。
5.在项目根目录下创建文件:bower.json，内容如下:
{
"name": "demo",
"description": "spring-boot and angularJS",
"version": "0.1.0-SNAPSHOT",
"keywords": [
"the first project of spring-boot and angularJS"
],
"private": true,
"ignore": [
"**/.*",
"node_modules",
"src/main/webapp/bower_components",
"src/main/webapp/lib",
"src/main/java",
"src/main/resources",
"src/test",
"target"
],
"dependencies": { //依赖的插件，bower install时将会下载的插件，具体作用自行百度（拷贝进去时这段注释要删掉）
"angular": "1.5.5",
"angular-resource": "1.5.5",
"angular-cookies": "1.5.5",
"angular-messages": "1.5.5",
"angular-animate": "1.5.5",
"angular-sanitize": "1.5.5",
"angular-aria": "1.5.5",
"angular-route": "1.5.5",
"angular-i18n": "1.5.5",
"angular-material": "1.0.4",
"angular-ui-router": "0.2.15",
"angular-ui-validate": "1.2.2",
"codemirror": "5.14.2",
"angular-ui-codemirror": "0.3.0",
"angular-loading-bar": "0.9.0",
"angular-local-storage": "0.2.7",
"angular-material-data-table": "0.10.9",
"angular-once": "0.1.9",
"moment": "2.10.6",
"angular-moment": "1.0.0-beta.3",
"Chart.js": "1.0.2",
"angular-chart.js": "0.8.8",
"angular-filter": "0.5.8",
"ng-file-upload": "^12.0.4",
"editor.md": "1.5.0",
"jquery": "3.1.0"
},
"devDependencies": {
"angular-mocks": "1.5.5",
"angular-scenario": "1.5.5"
},
"resolutions": {
"angular": "1.5.5",
"Chart.js": "1.0.2",
"moment": "2.10.6"
}
}显然，指定一会儿bower install时需要下载哪些插件。
6.cmd进入项目根目录下：执行bower install。安装完成后，将在第4步指定的目录下出现这些插件。接着执行下一步。
7.接下来并不是执行之前在gulpfile.js中定义的html task命令，而要先再index.html中添加如下代码:
<html>
<head>
<meta charset="UTF-8">
<title>first project of angularJS and spring-boottitle>
// 1
// 2
head>
<body ng-app>
// 3
//4
body>
html>添加1、2、3、4的注释必不可少，他将取决执行htmltask任务后，将bower install下载的插件引入到index.html中的哪个位置。
7.最后一步，cmd进入项目根目录下执行gulp html以便执行htmltask命令，打开index.html，便会发现，bower_components下的插件都被自动引入到指定的位置中了。如下：
<html>
<head>
<meta charset="UTF-8">
<title>Insert title heretitle>
<link rel="stylesheet" href="bower_components/angular-material/angular-material.css" />
<link rel="stylesheet" href="bower_components/codemirror/lib/codemirror.css" />
<link rel="stylesheet" href="bower_components/angular-loading-bar/build/loading-bar.css" />
<link rel="stylesheet" href="bower_components/angular-material-data-table/dist/md-data-table.css" />
<link rel="stylesheet" href="bower_components/angular-chart.js/dist/angular-chart.css" />
head>
