Vroom

JavaScriptEngineSwitcher.Vroom contains a VroomJsEngine adapter (wrapper for the VroomJs version 1.2.3 with support of V8 version 3.17.16.2).

For correct working of the VroomJs on Windows require the Visual C++ Redistributable for Visual Studio 2012 and the Microsoft Visual C++ 2015 Redistributable.

VroomJs package does not contains a native assemblies for Linux and OS X, but you can try to build them by using the following instruction from official repository.

Engine settings

You can specify a settings of JS engine during its registration:

engineSwitcher.EngineFactories.AddVroom(newVroomSettings{MaxYoungSpaceSize=4194304,MaxOldSpaceSize=8388608});

If you manually create an instance of JS engine, then you can pass settings via the constructor:

IJsEngineengine=newVroomJsEngine(newVroomSettings{MaxYoungSpaceSize=4194304,MaxOldSpaceSize=8388608});

Consider in detail properties of the VroomSettings class:

Property name	Data type	Default value	Description
MaxYoungSpaceSize	Int32	-1	Maximum size of the young object heap in bytes.
MaxOldSpaceSize	Int32	-1	Maximum size of the old object heap in bytes.

1. Not supported undefined type.
2. Errors when calling methods of embedded objects and types, that have several overloaded versions.
3. Errors when accessing to the fields of embedded objects.
4. Inability to embed the instances of delegates.
5. There's no method, that starts the garbage collection.
