Microsoft.JavaScript.NodeApi namespace

public type	description
interface IJSValue<TSelf>	A base interface for a struct that represents a JavaScript value type or a built-in object type. It provides functionality for converting between the struct and JSValue.
delegate JSActionCallback	Represents a low-level void function or method call or callback from JavaScript into .NET.
struct JSArray
struct JSAsyncIterable
struct JSBigInt
delegate JSCallback	Represents a low-level function or method call or callback from JavaScript into .NET.
struct JSCallbackArgs	Provides access to the arguments for a low-level JavaScript function call or callback, along with the this argument and an optional context object.
struct JSDate
class JSDispatcherQueue
class JSDispatcherQueueController
class JSDispatcherQueueTimer
struct JSError
enum JSErrorType
class JSEventEmitter	Event emitter that can be backed by either a Node.js EventEmitter object or a standalone (runtime-agnostic) listener tracker.
class JSException	An exception that was caused by an error thrown by JavaScript code or interactions with JavaScript objects.
class JSExportAttribute	Exports an item to JavaScript, optionally specifying the name of the export and whether it is the default export of the module.
struct JSFunction	Represents a JavaScript Function value.
class JSImportAttribute	Indicates a class or struct is imported from JavaScript.
class JSInvalidThreadAccessException	An exception that was caused by an attempt to access a JavaScript value without any JSValueScope established on the current thread, or from a thread associated with a different environment / root scope.
struct JSIterable
enum JSKeyCollectionMode
enum JSKeyConversion
[Flags] enum JSKeyFilter
struct JSMap
struct JSObject
struct JSPromise	Represents a JavaScript Promise object.
[Flags] enum JSPropertyAttributes
struct JSPropertyDescriptor	Describes a property of a JavaScript object, including its name, value, and attributes. Can be converted to a JavaScript property descriptor object using the ToObject method.
struct JSProxy	Enables creation of JS Proxy objects with C# handler callbacks.
class JSReference	A strong or weak reference to a JS value.
struct JSSet
struct JSSymbol
struct JSTypedArray<T>
enum JSTypedArrayType
struct JSValue
class JSValueScope	A scope that controls the lifetime of JS values. When the scope is disposed, any JS values created within the scope are released unless they are held by a strong JSReference.
class JSValueScopeClosedException	An exception that was caused by an attempt to access a JSValue (or a more specific JS value type, such as JSObject or JSArray) after its JSValueScope was closed.
enum JSValueScopeType	Indicates the type of JSValueScope within the hierarchy of scopes.
enum JSValueType
static class NodeApiStatusExtensions
static class TaskExtensions	Extension methods for converting between .NET tasks and JS promises.

Microsoft.JavaScript.NodeApi.Interop namespace

public type	description
struct JSAbortSignal	Represents a JavaScript AbortSignal object and supports conversion to and from CancellationToken.
struct JSAsyncScope	Helps preventing Node.JS process from exiting while we execute C# async functions.
struct JSCallbackDescriptor	Descriptor for a callback not associated with an object property, for example a constructor callback or standalone function callback. Enables passing a data object via the callback args data.
struct JSCallbackOverload	Holds overload resolution information (parameter types) for one of multiple overloads for a .NET method.
class JSClassBuilder<T>
static class JSCollectionExtensions
abstract class JSInterface	Base class for a dynamically generated interface adapter that enables a JS object to implement a .NET interface. Holds a reference to the underlying JS value.
class JSModuleAttribute	Designates a non-static class or static method that initializes the JS module.
class JSModuleBuilder<T>	Builds JS module exports.
class JSModuleContext	Manages JavaScript interop context for the lifetime of a .NET module.
abstract class JSPropertyDescriptorList<TDerived,TObject>
class JSRuntimeContext	Manages JavaScript interop context for the lifetime of the .NET Node API host.
abstract class JSSynchronizationContext	Manages the synchronization context for a JavaScript environment, allowing callbacks and asynchronous continuations to be invoked on the JavaScript thread that runs the environment.
delegate JSThreadSafeCallback
delegate JSThreadSafeFinalizeCallback
class JSThreadSafeFunction
static class NodeProcess	Provides information about, and control over, the current Node.js process.
class NodeStream	Represents a Node.js Duplex, Readable, or Writable stream.
class NodeWorker	A Node.js worker thread, as documented at https://nodejs.org/api/worker_threads.html.
static class TypeExtensions

abstract class JSRuntime	Abstract base class for a JavaScript runtime.
static class NativeLibrary	Provides APIs for managing native libraries.
class NodejsEnvironment	A Node.js runtime environment with a dedicated main execution thread.
class NodejsPlatform	Manages a Node.js platform instance, provided by libnode.
class NodejsRuntime
class TracingJSRuntime	Wraps a JSRuntime and traces all the calls from .NET to JS, including basic inspection of arguments, out values, and return status.
