gulp源图

Question

我需要帮助添加源代码映射到SASS编译器在相同的CSS输出文件夹。到目前为止，我已经在gulpfile.js中安装了gulp-sourcemaps模块，但是不知道是否能成功地将sourcemaps.write绑定为gulp.task。

任何帮助都是非常感谢的:)

var gulp = require('gulp');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var bs = require('browser-sync').create();

gulp.task('browser-sync', ['sass'], function() {
    bs.init({
    server: {
        baseDir: "./"
    },
    proxy: {
        target: "localhost:8080", // can be [virtual host, sub-directory, localhost with port]
        ws: true // enables websockets
    }
});
});

gulp.task('sass', function() {
    return gulp.src('scss/**/*.scss')
        .pipe(sourcemaps.init())
        .pipe(sass())
        .pipe(sourcemaps.write('.'))
        .pipe(gulp.dest('assets/css'))
        .pipe(bs.reload({
            stream: true
        }));
});

gulp.task('watch', ['browser-sync'], function () {
    gulp.watch("scss/*.scss", ['sass']);
    gulp.watch("*.php").on('change', bs.reload);
});

尝试以下代码来执行吞咽任务“sass”：

gulp.task('sass', function() {
    return gulp.src('scss/**/*.scss')
        .pipe(sourcemaps.init())
        .pipe(sass())
        .pipe(sourcemaps.write('.'))
        .pipe(gulp.dest('assets/css'))
        .pipe(bs.reload({
            stream: true
        }));
});

首先初始化源地图，然后编译sass()，然后将源地图写在同一个文件夹('.')中。

5个月以来，我每天都在使用这个任务，而且效果很好，

const gulp            = require('gulp'),
      autoprefixer    = require('gulp-autoprefixer'),
      plumber         = require('gulp-plumber'),
      sass            = require('gulp-sass'),
      sourcemaps      = require('gulp-sourcemaps');

var sassSourcePath = 'YourPath/scss/**/*.scss',
    cssDestPath    = 'YourPath/css/';


gulp.task('sass', () => {

  return gulp
    .src(sassSourcePath)
    .pipe(plumber())
    .pipe(sourcemaps.init())
    .pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))
    .pipe(sourcemaps.write({includeContent: false}))
    .pipe(sourcemaps.init({loadMaps: true}))
    .pipe(autoprefixer({ browser: ['last 2 version', '> 5%'] }))
    .pipe(sourcemaps.write('.'))
    .pipe(gulp.dest(cssDestPath));

});

我也推荐你生产版的require('gulp-csso')

一个完整的解决方案，用于gulp-sass，map，count all files，minify：

./sass/部分文件夹/index.scss

@import 'base/_reset';
@import 'helpers/_variables';
@import 'helpers/_mixins';
@import 'helpers/_functions';
@import 'base/_typography';
etc..

./gupfile.js

var gulp = require('gulp');
var sass = require('gulp-sass');
var concat = require('gulp-concat');
var uglifycss = require('gulp-uglifycss');
var sourcemaps = require('gulp-sourcemaps');

gulp.task('styles', function(){
    return gulp
            .src('sass/**/*.scss')
            .pipe(sourcemaps.init())
            .pipe(sass().on('error', sass.logError))
            .pipe(concat('styles.css'))
            .pipe(uglifycss({
                "maxLineLen": 80,
                "uglyComments": true
            }))
            .pipe(sourcemaps.write('.'))
            .pipe(gulp.dest('./build/css/'));
});


gulp.task('default', function(){
    gulp.watch('sass/**/*.scss', ['styles']);
})
