懶癌直接貼代碼，想寫(xiě)在寫(xiě)
因?yàn)樽罱懔艘幌滦〕绦颍苯邮褂梦⑿诺拈_(kāi)發(fā)者工具搞感覺(jué)有點(diǎn)不習(xí)慣，并且看了幾篇給小程序瘦身的博客，決定給自己的項(xiàng)目做一套配置文件，使用gulp來(lái)支持sass scss文件編譯以及上傳之前壓縮文件的空行之類(lèi)的。

至于使用gulp沒(méi)有使用webpack的原因，因?yàn)槲也幌胩幚韏s文件，可能是我研究明白吧。后續(xù)還可以添加把a(bǔ)ssets目錄里面的資源上傳到ftp或者cdn的功能~

JSON

json文件開(kāi)發(fā)時(shí)候直接復(fù)制到dist目錄下，生產(chǎn)的時(shí)候使用jsonminify壓縮

gulp.task('json',() => {
  return gulp.src('./src/**/*.json')
    .pipe(gulp.dest('./dist'))
})

gulp.task('jsonPro',  () => {
  return gulp.src('./src/**/*.json')
    .pipe(jsonminify())
    .pipe(gulp.dest('./dist'))
})

wxml

wxml文件開(kāi)發(fā)時(shí)候直接復(fù)制到dist目錄下，生產(chǎn)的時(shí)候使用htmlmin壓縮

gulp.task('templates', () => {
  return gulp.src('./src/**/*.wxml')
    .pipe(gulp.dest('./dist'))
})

gulp.task('templatesPro', () => {
  return gulp.src('./src/**/*.wxml')
    .pipe(htmlmin({
      collapseWhitespace: true,
      removeComments: true,
      keepClosingSlash: true
    }))
    .pipe(gulp.dest('./dist'))
});

wxss

wxss文件，這個(gè)處理就比較多了，沒(méi)有使用的時(shí)候只能使用css，對(duì)于我這種習(xí)慣sass的人來(lái)說(shuō)有點(diǎn)痛苦。于是添加了sass支持，支持了.sass后綴的文件，會(huì)編譯成wxss格式的，原有wxss文件中也支持了scss語(yǔ)法

gulp.task('wxss', () => {
  var combined = combiner.obj([
    gulp.src(['./src/**/*.{wxss,sass}', '!./src/styles/**']),
    sass().on('error', sass.logError), // gulp sass編譯
    autoprefixer([
      'iOS >= 8',
      'Android >= 4.1'
    ]), // autoprofixer 自動(dòng)添加
    rename((path) => path.extname = '.wxss'), //重命名
    gulp.dest('./dist')
  ]);

  combined.on('error', handleError);
});

gulp.task('wxssPro', () => {
  var combined = combiner.obj([
    gulp.src(['./src/**/*.{wxss,sass}', '!./src/styles/**']),
    sass().on('error', sass.logError),
    autoprefixer([
      'iOS >= 8',
      'Android >= 4.1'
    ]),
    minifycss(), // 壓縮 css文件
    rename((path) => path.extname = '.wxss'),
    gulp.dest('./dist')
  ]);

  combined.on('error', handleError);
});

JavaScript

雖說(shuō)微信的IDE也支持ES6，但是還不是很完善，所以我使用Babel編譯js。使用uglify壓縮的js

gulp.task('scripts', () => {
  return gulp.src('./src/**/*.js')
    .pipe(babel({
      presets: ['es2015']
    }))
    .pipe(gulp.dest('./dist'))
})

gulp.task('scriptsPro', () => {
  return gulp.src('./src/**/*.js')
    .pipe(babel({
      presets: ['es2015']
    }))
    .pipe(uglify({
      compress: true,
    }))
    .pipe(gulp.dest('./dist'))
})

gulpfile.js

  gutil.log(colors.red('Error!'))
  gutil.log('fileName: ' + colors.red(err.fileName))
  gutil.log('lineNumber: ' + colors.red(err.lineNumber))
  gutil.log('message: ' + err.message)
  gutil.log('plugin: ' + colors.yellow(err.plugin))
