Use gulp-if instead of gulp-filter

[yocontra]

gulp.task('sometask', function () {
    var jsFilter = $.filter('**/*.js');
    return gulp.src('app/*.html')
      .pipe(jsFilter)
      .pipe(uglify())
      .pipe(jsFilter.restore())
      .pipe(otherstuff)
      .pipe(gulp.dest('stuff'))
});

becomes

gulp.task('sometask', function () {
    return gulp.src('app/*.html')
      .pipe(gif('*.js', uglify()))
      .pipe(otherstuff)
      .pipe(gulp.dest('stuff'))
});

gulp-if provides a nice way to apply portions of the pipeline only when the file matches a regex, function, glob, boolean, etc.

Thanks for the tip @contra!

👍 much better. we should do that on generator-gulp-webapp too :)

I actually just sat down with the author of the plugin and rewrote it - it's super cool now. It's essentially a streaming ternary operation at it's core, with some gulp-specific sugar for globbing and whatnot.

@contra any way to run multiple gulp plugins when the condition is true?

@sindresorhus lazypipe or construct the stream ahead of time. You have to pass gulp-if the head of the stream, where .pipe returns the last item so you can see how gif(stuff, css.pipe(csso)) is a problem since it writes to csso
