Node.js

On Node.js, socket uses the built-in net.Socket API for TCP connections.

Implementation Details​

The JavaScript target wraps Node.js net.Socket:

  • Async connect/read/write via Node.js event-driven API
  • Buffer data bridged between Kotlin ReadBuffer/WriteBuffer and Node.js Buffer

Browser​

The browser target throws UnsupportedOperationException for socket operations, as browsers do not provide raw TCP socket access.

Requirements​

  • Node.js runtime (for net module access)

Testing​

./gradlew jsNodeTest

Note: The tcp-port-used npm package is used in tests to verify port availability.
