Run two projects in single launch.json - asp.net-core

Question

I have two projects with common root opened in visual code. First is .net core webapi. Second is frontend on react/redux etc. Now when I want to run application I need to manually from console run 'npm start' and then run webapi from visual code. How can I achieve this with configuration of vs code?
At then end I want that after clicking debug I will have recompiled and deployed webapi and rebuild and same with frontend app. Then open browser in desired page.
There is an idea that I can run some script that would handle that, but I would prefer do it with pure vs code configuration.
I think that I need to modify my launch.json file. Don't know how though.
This is launch.json https://pastebin.com/9a66n3Rx
