JS Optimizer for GameMaker Studio HTML5 export:

As you may have noticed, after you export your GM:S project to HTML5 and you look into the js file, you can see that there is a lot of unnecessary functions that you don't need so they could be removed, but cleaning it by your hands would be very, very tedious and quite useless, because after the next export you would have to do that again which is unacceptable and so because here is this utility, that cleans it up for you, which is great. It's in early access, but it's already able to remove some unnecessary code from your js that you don't need, and it's also able to reduce and optimize your code to improve speed and reduce loading time.

Key features:

  • Reduce the size
  • Improve loading time
  • Improve the overall speed
  • Compatible with GM:S 1 and GMS 2

To do:

  • Improve overall speed
  • Add more features and improve cleaning/optimization technique
  • Add support for parameters (commands)
  • Fix bugs and clean up the code

Notice: it's still in developement and it needs a lot of testing, so it's possible that some parts might not work as expected.
So if you find some bugs or if you have any suggestions please report it here or to our bug tracker thanks!

Currently available for windows only, mac or linux version can be added on request.

TIP: If you want to see the details during the progress you can set  debug log output "JSOptimizer.exe -output debug.log"
