What is the role Nodejs in .NET 5 Blazor WebAssembly

When you create new .NET 5 Blazor WebAssembly project from Visual Studio 2019 and then run it, Windows Firewall asks for permission for Nodejs.

Why do I need Nodejs? What is its role in .net 5 blazor webassembly project and why does it want to connect to internet?? What happens if I don't allow Nodejs in my firewall?

NodeJS is required to allow debugging client side code from Visual Studio. It plays the role of a debug proxy. In case of a Blazor code runing in a browser, the real debugger is the Mono debugger which is part of Blazor runtime. To communicate with the debugger, VS uses Node which plays the role of a mapper between the code seen in VS and the one loaded in the browser and communicates with the browser using Chrome DevTools Protocol. For more details see: Blazor documentation and this CaptainSafia's blog post.
