javascript – gulp观看并重新加载jekyll,sass,js

我正在尝试构建一个gulpfile,它将观看jekyll / sass / js并与浏览器同步.
该脚本正确地监视jekyll的更改,重建并在浏览器中注入所有更改.

但我无法弄清楚为什么它没有同步sass / js的变化,即使它们已经被观看过了.再生.任何帮助将不胜感激！

/*** gulp.js ***/

var gulp         = require('gulp');

var package      = require('./package.json');

var messages        = {
    jekyllBuild: '<span style="color: grey">Running:</span> $jekyll build'

/**

gulp.task('jekyll-build', function (done) {
    browserSync.notify(messages.jekyllBuild);
    return cp.spawn('jekyll', ['build'], {stdio: 'inherit'})
        .on('close', done);
});

/**

 */
gulp.task('jekyll-rebuild', ['jekyll-build'], function () {
    browserSync.reload();
});

/**
 * Wait for jekyll-build, then launch the Server
 */
gulp.task('browser-sync', ['css', 'js', 'jekyll-build'], function() {
    browserSync({
        server: {
            baseDir: 'html'
        }
    });
});

gulp.task('css', ['bs-reload'], function () {
    return gulp.src('themes/dental-theme/assets/scss/main.scss')
    .pipe(sass({errLogToConsole: true}))
    .pipe(autoprefixer(['last 15 versions', '> 1%', 'ie 8', 'ie 7'], { cascade: true }))
    .pipe(gulp.dest('build/css'))
    .pipe(minifyCSS())
    .pipe(rename({ suffix: '.min' }))
    .pipe(header(banner, { package : package }))

gulp.task('bs-reload', function () {
    browserSync.reload();
});

gulp.task('default', ['css', 'js', 'browser-sync'], function () {
    gulp.watch("themes/dental-theme/assets/scss/*.scss", ['css']);
    gulp.watch("themes/dental-theme/assets/js/*.js", ['js']);
    gulp.watch(['index.html', '_layouts/*.html', '_posts/*'], ['jekyll-rebuild']);
});

解决方法:

你的js和css手表只是重新生成文件,但没有做一个Jekyll构建,你的html手表.

试试：

gulp.task('default', ['css', 'js', 'browser-sync'], function () {
    gulp.watch("assets/scss/*/*.scss", ['css', 'jekyll-rebuild']);
    gulp.watch("assets/js/*.js", ['js', 'jekyll-rebuild']);
    gulp.watch(['index.html', '_layouts/*.html', '_posts/*'], ['jekyll-rebuild']);
});

编辑：

如果您不想每次只复制生成资产到目标文件夹,那么您不想构建您的Jekyll：

gulp.task('default', ['css', 'js', 'browser-sync'], function () {
    gulp.watch("assets/scss/*/*.scss", ['css', 'css-to-site']);
    gulp.watch("assets/js/*.js", ['js', 'js-to-site']);
    gulp.watch(['index.html', '_layouts/*.html', '_posts/*'], ['jekyll-rebuild']);
});

gulp.task('js-to-site', function () {
  gulp.src('build/js/*')
    .pipe(gulp.dest('html/themes/dental-theme/js'));
    browserSync.reload();
});

gulp.task('css-to-site', function () {
  gulp.src('build/css/*')
    .pipe(gulp.dest('html/themes/dental-theme/css'));
    browserSync.reload();
});

没有测试过.
