This patch enables source maps in pgAdmin4 for development environment.
On running yarn run bundle It will create source maps(i.e. extract each module js file so that it is available to debug).
You can search each module(ie. menu.js to debug) file by filename as follows:
Start pgAdmin4 server or run separately yarn run bundle in pgadmin/web
Open pgAdmin4 in browser(I am using chrome). Click sources panel and press CMD+P and search for file menu.js. Click and then add breakpoint to the line where you want to debug codebase. Screenshot attached for reference.
I have excluded vendor and codemirror bundle from source map as i believe we don’t debug these files. If someone needs, they can remove vendor.js from source map plugin and rebuild.
