My setup where some GWT modules are running both standalone but also inside in iframes. If you add HTTPS to the mix, having to constantly edit bookmarklets is not fun.
So I created this little extension that you can find here: https://github.com/vasvir/gwt-sdm-compile
From the README:
This extension replaces the following bookmarklets:
It works in Firefox and Chrome and it is Manifest V3 based.The extension scans for all GWT modules in all frames (main window and iframes) but iframes with different origin do not work in Firefox currently.
The extension provides some rudimetary support to save the configuration so it can be reused for the specific module/protocol combination. This is useful when you have multiple GWT modules or HTTPS setups as described here https://vasvir.wordpress.com/2017/02/07/gwt-super-dev-mode-https-setup-in-7-steps/
Hope that you will find this useful.
