How to ignore a directory in gulp?

Question

gulp.js

Tell me how to set it up so that it monitors all folders except for ... the necessary one,
let's say in the app folder there is a certain subset of directories that you need to monitor and from them the "bad" folder needs to be skipped

gulp.task('task',function(){
        gulp.watch('app/**/**.js',['run'])
})

Answer 1

gulp.watchuses vinyl-fs , which uses gaze , which finally uses minimatch . Therefore, you can ignore files/folders like this !./js/*.min.*.
fs.src(["./js/**/*.js", "!./js/vendor/*.js"])
