gulp使用详解

gulp.src(‘client/templates/*.jade‘)
  .pipe(jade())
  .pipe(minify())
  .pipe(gulp.dest(‘build/minified_templates‘));

gulp.src(‘client/js/**/*.js‘) // 匹配‘client/js/somedir/somefile.js‘ 并且自动设置 `base` 为 `client/js/`
  .pipe(minify())
  .pipe(gulp.dest(‘build‘));  // 写入 ‘build/somedir/somefile.js‘ gulp.src(‘client/js/**/*.js‘, { base:‘client‘ })  // 制定base 为‘client‘

  .pipe(minify())
  .pipe(gulp.dest(‘build‘));  // 写入 ‘build/js/somedir/somefile.js‘ 

gulp.task(‘buildStuff‘, function() {
  // Do something that "builds stuff"
  var stream = gulp.src(/*some source path*/)
  .pipe(somePlugin())
  .pipe(someOtherPlugin())
  .pipe(gulp.dest(/*some destination*/));

  return stream;
  });

var gulp = require(‘gulp‘);

// 注意fn有一个回调参数，所以当任务完成的时候，会调用这个cb，进程就会知道该任务完成了
gulp.task(‘one‘, function(cb) {
    // do stuff -- async or otherwise
    cb(err); // if err is not null and not undefined, the run will stop, and note that it failed
});

// 申明了一个任务two，必须在one完成之后才能执行
gulp.task(‘two‘, [‘one‘], function() {
    // task ‘one‘ is done now
});
//默认我们是申明要执行两个任务，这两个任务会同时初始化，但是任务two会因为有依赖延迟执行
gulp.task(‘default‘, [‘one‘, ‘two‘]);
