Not many are familiar with this awesome feature of dotnet core. Aspnet
team is actively maintaining a project named JavascriptServices
; Along with other packages, it includes the NodeServices
package. Using this package, one can easily create an instance of node
and execute JavaScript code (function) in the backend. If you think of it right now, you can see that it actually opens up a wide variety of development opportunities. By opportunities, I mean; the ASP.NET core project is trying hard to make its package eco-system (NuGet) rich but while doing it, why not get advantages of other package eco-system as well, right? When I talk about other than nuget package manager, the first name that comes to my mind is Npm
(node package manager). Npm
is the largest package manager out there on this very day and its growing rapidly. By using NodeServices
package, we can now use (not all of the npm
packages but) most of the npm
packages in our backend development. So, let me show you how to configure NodeServices
in your aspnet core project and use it to execute JavaScript code on the backend.

Json.NET 8.0 منتشر شد
To reduce allocations and memory usage when serializing Json.NET 8.0 adds a new IArrayPool interface. Json.NET is already very lean when it comes to allocations, working with raw characters on array buffers instead of allocated strings, but those buffers can easily grow large, and a new buffer is created each time JSON is read or written. IArrayPool allows array buffers to be reused, similar to connection pooling with a database, or thread pooling in .NET.
