Angular - 在index.html中合併所有JS文件的最佳做法

Question

我有我的Angular應用程序，其中我的index.html列出了我所有的服務和控制器JS文件。

例如很多這些行<script src="services/loginService.js"></script>

爲了進入生產我想簡化這個，只是引用一個js文件（這是一個縮小版本）。

有人發現有用的工具是什麼工具？

我在猜測吞嚥？

任何意見，將不勝感激。

謝謝。

在咽，可以如下做到這一點：

下面是一個簡單gulpfile我已經建立了本地。您可以使用腳本任務或useref任務。 Useref允許你指定哪些文件應該被縮小。

// Include gulp 
var gulp = require('gulp'); 

// Include Our Plugins 
var jshint = require('gulp-jshint'); 
var sass = require('gulp-sass'); 
var concat = require('gulp-concat'); 
var uglify = require('gulp-uglify'); 
var gulpIf = require('gulp-if'); 
var rename = require('gulp-rename'); 
var babel = require('gulp-babel'); 
var webserver = require('gulp-webserver'); 
var connect = require('gulp-connect'); 
var gulpIgnore = require('gulp-ignore'); 
var useref = require('gulp-useref'); 
var minifyCSS = require('gulp-minify-css'); 
var autoprefixer = require('gulp-autoprefixer'); 
var rename = require('gulp-rename'); 
var cssnano = require('gulp-cssnano'); 
var imagemin = require('gulp-imagemin'); 

var outputDir = 'dist'; 
var jsLintIgnore = 'app/js/bootstrap-3.3.6/**/*.js'; 

// run a local webserver from app directory 
gulp.task('webserver', function() { 
    gulp.src('app') 
    .pipe(webserver({ 
     livereload: true, 
     fallback: './src/index.html', 
     //port: 8000, // Default is 8000 
     //directoryListing: true, 
     open: true 
    })); 
}); 

// Lint Task - checks any JavaScript file in our js/ directory and makes sure there are no errors in our code. 
gulp.task('lint', function() { 
    return gulp.src('app/js/**/*.js') 
     .pipe(jshint()) 
     //.pipe(gulpIgnore.include(jsLintIgnore)) 
     .pipe(jshint.reporter('default')); 
}); 


gulp.task('useref', function(){ 
    return gulp.src('app/*.html') 
    .pipe(useref()) 
    // Minifies only if it's a JavaScript file 
    .pipe(gulpIf('js/**/*.js', uglify())) 
    .pipe(gulpIf('css/**/*.css', cssnano())) 
    .pipe(gulp.dest('dist')) 
}); 

// Compile Our Sass - compiles any of our Sass files in our scss/ directory into CSS and saves the compiled CSS file in our dist/css directory. 
gulp.task('sass', function() { 
    return gulp.src('app/scss/**/*.scss') 
     .pipe(sass()) 
     .pipe(gulp.dest('app/css')); 
}); 

gulp.task('css', function(){ 
    gulp.src('app/css/**/*.css') 
     .pipe(minifyCSS()) 
     .pipe(rename('style.min.css')) 
     .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9')) 
     .pipe(gulp.dest('dist/css')) 
}); 

gulp.task('images', function(){ 
    return gulp.src('app/images/**/*.+(png|jpg|gif|svg)') 
    .pipe(imagemin()) 
    .pipe(gulp.dest('dist/images')) 
}); 

// Concatenate & Minify JS - concatenates all JavaScript files in our js/ directory and saves the ouput to our dist/js directory. Then gulp takes 
// that concatenated file, minifies it, renames it and saves it to the dist/js directory alongside the concatenated file. 
gulp.task('scripts', function() { 
    return gulp.src('app/js/**/*.js') 
     .pipe(concat('all.js')) 
     .pipe(gulp.dest('dist')) 
     .pipe(rename('all.min.js')) 
     .pipe(uglify()) 
     .pipe(gulp.dest('dist/js')); 
}); 

// Watch Files For Changes - run tasks as we make changes to our files. 
gulp.task('watch', function() { 
    gulp.watch('app/js/**/*.js', ['lint', 'scripts']); 
    gulp.watch('app/scss/**/*.scss', ['sass']); 
}); 

// Default Task - used as a grouped reference to our other tasks. This will be the task that is ran upon entering gulp into the command line without any additional parameters. 
gulp.task('default', ['webserver', 'lint', 'sass', 'useref','images', 'watch']); 

在你的HTML，你想包你想與以下minifed的js文件：

<!--build:js js/main.min.js --> 

<script src="/js/script1.js"></script> 
<script src="/js/script2.js"></script> 
<script src="/js/script3.js"></script> 

<!-- endbuild --> 

這將創建一個名爲縮小的文件：JS/main.min.js在DIST文件夾中。正如你所看到的，我對我的css文件也一樣。您可以在標籤包裝他們也瞄準某些或所有的CSS文件：

<!--build:css css/styles.min.css--> 
    <link rel="stylesheet" href="/css/styles1.css"> 
    <link rel="stylesheet" href="/css/styles2.css"> 
    <link rel="stylesheet" href="/css/styles3.css"> 
    <!--endbuild--> 

這一飲而盡文件採用以下目錄結構，但你可以改變它來適應你的環境：

- Root Folder 
    - /app (development environment) 
    - /css 
    - /images 
    - /js 
    - /scss 
    - index.html 
    - /dist (production version of site here) 
    - /css 
    - /images 
    - /js 
    - index.html 
    - /node_modules 
    - bower.json 
    - gulpfile.js 
    - package.json

現在說了所有這些，我更喜歡webpack。雖然它的學習曲線有點陡峭，但Gulp可能是一個開始的好地方。
