如何获取gulp + babel + browserify + uglify的源图

Question

我正在使用gulp将browserify + babelify与uglifyjs捆绑在一起.但是,从我的项目生成的源图只给了我捆绑的版本,而不是捆绑的版本.

这是我的设置:

var gulp       = require('gulp'),
    source     = require('vinyl-source-stream'),
    browserify = require('browserify'),
    gutil      = require('gulp-util'),
    buffer     = require('vinyl-buffer'),
    sourcemaps = require('gulp-sourcemaps'),
    uglify     = require('gulp-uglify'),
    file       = 'index.js';

gulp.task('build', function(){
    return browserify({
        entries: [file],
        transform: ["babelify"]
      })
    .bundle()
    .pipe(source(file))
    .pipe(buffer())
    .pipe(sourcemaps.init({loadMaps: true}))
    .pipe(uglify())
    .pipe(sourcemaps.write('./'))
    .pipe(gulp.dest('./public/js'))
    .pipe(gutil.noop())
})

有没有办法让我创建一个捆绑babel => browserify => uglify并仍然将地图返回给我的pre-babel文件的构建？

我也不介意不使用gulp(我实际上更喜欢咕噜声,但这个设置过去常常适合我).

首先,您需要通过将debug选项设置为true来设置browserify以生成源映射,然后如果您需要pre babelify源映射,则需要配置babelify以生成源映射:

   var gulp       = require('gulp'),
    source     = require('vinyl-source-stream'),
    browserify = require('browserify'),
    gutil      = require('gulp-util'),
    buffer     = require('vinyl-buffer'),
    sourcemaps = require('gulp-sourcemaps'),
    uglify     = require('gulp-uglify'),
    babelify   = require('babelify')
    file       = 'index.js';

gulp.task('build', function(){
    return browserify(file,{debug:true}).transform(babelify, {presets: ["es2015", "react"],sourceMaps:true})
    .bundle()
    .pipe(source(file))
    .pipe(buffer())
    .pipe(sourcemaps.init({loadMaps: true}))
    .pipe(uglify())
    .pipe(sourcemaps.write('./'))
    .pipe(gulp.dest('./build/js'))
    .pipe(gutil.noop())
})
