gulp-watch

问题 Can I use gulp-imagemin plugin with gulp-watch? So, I need to optimize images as soon as they are put into the folder. Here is a part of my gulpfile.js: var gulp = require('gulp'); var imagemin = require('gulp-imagemin'); var pngquant = require('imagemin-pngquant'); gulp.task('default', function() { gulp.watch('dist/images/**', function(event) { gulp.run('images'); }); }); // Image files gulp.task('images', function () { return gulp.src('src/images/*') .pipe(imagemin({ progressive: true,

问题 Hi I have a web application runnig on the Aurelia CLI. From what I’ve read in the documentation, the Aurelia CLI runs always “bundled” and never targeting directly source files. By running the “au run –watch” command, Aurelia “listens” to file changes and recreates the app-bundle.js automatically. Sample output from console: Starting 'readProjectConfiguration'... Finished 'readProjectConfiguration' Starting 'processMarkup'... Starting 'processCSS'... Starting 'configureEnvironment'...

问题 I am trying to pass a parameter to a task that is being invoked by gulp-watch. I need it because I am trying to build a modular framework. So if a file changes in module 1, the other modules don't need to be rebuild. And I want just one function to create the concatted & uglified files per module. This is what I got so far: //here I need the 'module' parameter gulp.task('script', function(module) { ... } gulp.task('watch', function() { gulp.watch('files/in/module1/*.js', ['script']); //here I

问题 I'm trying to run a task whenever a file get's changed, delete or a new file is added. The first two work, however: when a new file is added it's not being picked up. I installed the package gulp-watch and I have this task: var gulp = require('gulp'), watch = require('gulp-watch'); gulp.task('watch', function() { watch( ['./src/Scripts/**/*.js'], function(ev, cb) { console.log('test'); cb(); }); }); 回答1: That was a weird problem. Removing ./ from glob fixes it. var gulp = require('gulp'); var

问题 With gulp you often see patterns like this: gulp.watch('src/*.jade',['templates']); gulp.task('templates', function() { return gulp.src('src/*.jade') .pipe(jade({ pretty: true })) .pipe(gulp.dest('dist/')) .pipe( livereload( server )); }); Does this actually pass the watch'ed files into the templates task? How do these overwrite/extend/filter the src'ed tasks? 回答1: I had the same question some time ago and came to the following conclusion after digging for a bit. gulp.watch is an eventEmitter
