gulp配置

Gulp.js 是一个自动化构建工具,开发者可以使用它在项目开发过程中自动执行常见任务。

整个文件项目的目录如下图：

1、全局安装gulp：npm install --global gulp

2、安装项目开发依赖：npm install --save-dev gulp

3、安装package.json：yarn init -y

配置package.json文件：

{
  "name": "gulp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo "Error: no test specified" && exit 1"
  },
  "author": "iceStone <ice@wedn.net> (http://wedn.net/)",
  "license": "ISC",
  "devDependencies": {
    "browser-sync": "^2.11.1",
    "del": "^2.2.0",
    "gulp": "^3.9.0",
    "gulp-autoprefixer": "^3.1.0",
    "gulp-base64": "^0.1.3",
    "gulp-concat": "^2.6.0",
    "gulp-cssnano": "^2.1.0",
    "gulp-font-spider": "^0.3.6",
    "gulp-htmlmin": "^1.3.0",
    "gulp-imagemin": "^3.3.0",
    "gulp-less": "^3.0.5",
    "gulp-rev": "^7.1.2",
    "gulp-rev-collector": "^1.2.2",
    "gulp-uglify": "^3.0.0"
  }
}

4、创建gulpfile.js：touch gulpfile.js

配置gulpfile.js文件：

var gulp = require('gulp');
var less = require('gulp-less');
var cssnano = require('gulp-cssnano');
var base64 = require('gulp-base64');
var imagemin = require('gulp-imagemin');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var htmlmin = require('gulp-htmlmin');
var browserSync = require('browser-sync');
var rev = require('gulp-rev');
var revCollector = require('gulp-rev-collector');

var fontSpider = require( 'gulp-font-spider' );

gulp.task('css',['images'],function() {
  gulp.src(['src/css/*.less', '!src/css/_*.less'])
     .pipe(less())
       .pipe(base64({
          extensions: ['png', /.jpg#datauri$/i],
          exclude:    [/.server.(com|net)/dynamic//, '--live.jpg'],
          maxImageSize: 800*1024,
          debug: true
      }))
    .pipe(concat('style.min.css'))
    .pipe(cssnano())
    .pipe(gulp.dest('dist/css'))
    .pipe(browserSync.reload({
      stream: true
    }));
});


gulp.task('images',function(){
    gulp.src('./src/images/*')
     .pipe(gulp.dest('dist/images'))
});

gulp.task('js', function() {
  gulp.src('src/js/*.js')
    .pipe(concat('all.js'))
    .pipe(uglify())
    .pipe(gulp.dest('dist/js'))
    .pipe(browserSync.reload({
      stream: true
    }));
});


gulp.task('html', function() {
  gulp.src('src/*.html')
    .pipe(htmlmin({
      collapseWhitespace: true,
      removeComments: true
    }))
    .pipe(gulp.dest('dist'))
    .pipe(browserSync.reload({
      stream: true
    }));
});

gulp.task('md5',function(){
    gulp.src('dist/css/*.css')
      .pipe(rev())
      .pipe(gulp.dest('dist/css/'))
      .pipe(rev.manifest())
      .pipe(gulp.dest('dist/config'))
})

gulp.task('top',function(){
    gulp.src(['./dist/config/*.json', './dist/*.html'])
      .pipe(revCollector())
      .pipe(gulp.dest('./dist/'))
})

gulp.task('fontspider', function() {
     return gulp.src('./src/index.html')
   .pipe(fontSpider())

        // .pipe(fontSpider({
    //         silent: false,
    //         backup: false,
    // }))
    .pipe(gulp.dest('./dist/font'))
});



gulp.task('server', function() {
  browserSync({
    server: {
      baseDir: ['dist']
    },
  }, function(err, bs) {
    console.log(bs.options.getIn(["urls", "local"]));
  });

  gulp.watch('src/*.html',['html']);
  gulp.watch('src/css/*.less',['css']);
  gulp.watch('src/js/*.js',['js']);
  gulp.watch('src/fonts/*.otf', ['fontspider'])

});

5、运行gulp：gulp server

梦想还是要有，万一实现了呢？
