Hi, you can use WUIC: it's an open source project providing tools for compression with various libraries (closure and yuicompressor are good examples). Build time and on the fly optimization are supported. A servlet is provided and can do everything for you, including caching and gziping the content. A filter can also be installed to use HTTP/2 server-push when your HTML page is served.
Examples are here: https://github.com/wuic/wuic-samples Doc is here: http://wuic.github.io/wuic-documentation.html 2016-07-18 13:23 GMT+02:00 Carey Evans <ca...@carey.geek.nz>: > On Mon, 18 Jul 2016, at 07:15, Emmeran Seehuber wrote: > > For state of the art JS compression you need uglifyjs2 - you can run it > > on Rhino and I think even on Nashorn.
