we are migrating our app to the new angular ssr too. We have exactly the same problem. We can't directly use the new builder:application because we need to put the built browser into a subfolder and the property outputPath not allows to put subfolder so we kept the builder browser-esbuild for front and builder:server for the back BUT now how can i start my app like we did with ngUniversal ? We can't specify serverTarget anymore. Did you find a trick ? Regards
