I am running Visual Studio 2017 and use the Task Runner to run tasks in my gulpfile . I recently updated a gulp task to ES6 and now am getting this error: Failed to run "C:\Users\nz9rcn\Code\WebUI\Gulpfile.js"... cmd.exe /c gulp --tasks-simple C:\Users\nz9rcn\Code\WebUI\gulp-tasks\lesslint.js:5 let fail = false; ^^^ SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode at exports.runInThisContext (vm.js:53:16) at Module._compile (module.js:373:25) at Object.Module._extensions..js (module.js:404:10) at Module.load (module.js:343:32) at

I wondered if there is a way to have notify display a message on gulp-sass error. preferably the actual message that is displayed in the console. my gulp task looks like this: gulp.task('styles', function() { return gulp.src('src/scss/style.scss') .pipe(sass({ style: 'compressed', errLogToConsole: true })) .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9', 'opera 12.1', 'ios 6', 'android 4')) .pipe(gulp.dest('')) .pipe(livereload(server)) .pipe(notify({ message: 'Styles task complete' })); }); I'd like to pipe the notify to some kind of error callback. Any help appreciated. After

I have the following sass task which compiles app.scss to app.css and reloads the page: gulp.task('sass', function() { return gulp.src('./app/app.scss') .pipe(sass()) .pipe(gulp.dest('./app')) .pipe(livereload()); }); Now, I want to compile another file, namely ui-toolkit.scss to ui-toolkit.css . Is this the best way to update the task? gulp.task('sass', function() { gulp.src('./ui-toolkit/ui-toolkit.scss') .pipe(sass()) .pipe(gulp.dest('./ui-toolkit')); return gulp.src('./app/app.scss') .pipe(sass()) .pipe(gulp.dest('./app')) .pipe(livereload()); }); Just specify glob(s) that match multiple

In my office we are using gulp to build our less files. I wanted to improve the build task as it took over a second to build on a large project we recently worked on. The idea was to cache the files and only pass the one that changed. So I started with google and found incremental builds for javascript ang thought it would be easy to rewrite them for less. Here's the one I started with: https://github.com/gulpjs/gulp/blob/master/docs/recipes/incremental-builds-with-concatenate.md After a few unsuccessful tries I ended up with following code (tested with the latest bootstrap distribution): var

Short of it: started using Gulp recently (convert from Grunt), and am trying to use both Gulp's default watch task (not gulp-watch from npm) for SASS/JS/HTML and gulp-nodemon (from npm) to restart an Express server upon changes. When running just gulp watch , it works fine; and when running gulp server (for nodemon) that works fine. However, using both together (shown below in the configuration of the default task), the watch stuff isn't working. The task is running, and on the CLI gulp shows 'Starting' and 'Finished' for the watch tasks, but the files don't update. Relevant task

I'm trying to setup Gulp in my install of Laravel 5.1. I've ran then command npm install as specified in the Laravel documentation and that's worked fine. However, when I now run the command gulp I get the following message: ubuntu@NAME:/var/www/html/FOLDER# gulp [14:04:56] Using gulpfile /var/www/html/FOLDER/gulpfile.js [14:04:56] Starting 'default'...

I recently switched from browserify to webpack and the build time jumped from 4s to 16s on (2014 MBP). I understand webpack does alot more than browserify but i shouldn't take that long. My build process is fairly simple. Are there any tips or options to improve my build time? var webpackOptions = { cache : true, output: { filename: '[name].js', }, module: { loaders: [ { test: /\.js$/, loader: 'jsx-loader' }, { test: /\.css$/, loader: "style!css" } ] }, }; gulp.task('buildJs', function(){ multipipe( gulp.src(jsSrcPath), named(), webpack(webpackOptions), uglify(), gulp.dest(jsDestPath) ).on(
