Support for compression level

[tyke]

Would love support for compression level

[jstuckey]

Sure. I'll add an options object that will get passed directly to the gzip stream. That way compression level, chunkSize, etc. can all be set for gzip.

I had implemented those options in my pr, but then just realised that its pointless - default level (6) is most balanced on speed/compression.

[jstuckey]

Think it's worth adding? I don't see the harm in making the option available.

Actualy i started pr with that problem in mind, but never used it. Its worth, its just couple of locs. Actually i used custom zlib properties once - i had busy logining infrastructure (.5-2m insert/s), and had to put logs in queue with bulk compression. Ive set Z_SYNC_FLUSH and cranked up memLevel, but that was an edge case.

I'd welcome support for a compression level option, too.

Thanks for the input. I'm in the process of adding this feature. Should be out today or tomorrow.

Thanks!

I added a gzipOptions config in version 0.0.8. This can be used to pass any of the usual options to zlib.Gzip

Example:

var gulp = require('gulp');
var gzip = require('gulp-gzip');

var config = {
    gzipOptions: {
        level: 9,
        memLevel: 9
    },
    append: true
};

gulp.task('default', function() {
    gulp.src('...')
        .pipe(gzip(config))
        .pipe(gulp.dest('...'));
});
