OutOfProcessNodeInstance Class

Definition

Namespace:

Microsoft.AspNetCore.NodeServices.HostingModels

Assembly:

Microsoft.AspNetCore.NodeServices.dll

Package:

Microsoft.AspNetCore.NodeServices v3.1.18

Source:

OutOfProcessNodeInstance.cs

Caution

Use Microsoft.AspNetCore.SpaServices.Extensions

Class responsible for launching a Node child process on the local machine, determining when it is ready to accept invocations, detecting if it dies on its own, and finally terminating it on disposal.

This abstract base class uses the input/output streams of the child process to perform a simple handshake to determine when the child process is ready to accept invocations. This is agnostic to the mechanism that derived classes use to actually perform the invocations (e.g., they could use HTTP-RPC, or a binary TCP protocol, or any other RPC-type mechanism).

Methods

Dispose()	Disposes this instance.
Dispose(Boolean)	Disposes the instance.
Finalize()	Implements the finalization part of the IDisposable pattern by calling Dispose(false).
InvokeExportAsync<T>(CancellationToken, String, String, Object[])	Asynchronously invokes code in the Node.js instance.
InvokeExportAsync<T>(NodeInvocationInfo, CancellationToken)	Asynchronously invokes code in the Node.js instance.
OnErrorDataReceived(String)	Virtual method invoked whenever the Node.js process emits a line to its stderr.
OnOutputDataReceived(String)	Virtual method invoked whenever the Node.js process emits a line to its stdout.
PrepareNodeProcessStartInfo(String, String, String, IDictionary<String,String>, Boolean, Int32)	Configures a ProcessStartInfo instance describing how to launch the Node.js process.
