WebTransportError: WebTransportError() constructor

The WebTransportError() constructor creates a new WebTransportError object instance.

Note: This feature is available in Web Workers

Syntax

js

new WebTransportError(init)

Parameters

init Optional

An object containing the following properties:

message

A string describing the error that has occurred.

streamErrorCode

A number in the range 0-255 indicating the application protocol error code for this error.

Examples

A developer would not use this constructor manually. A new WebTransportError object is constructed when an error related to WebTransport occurs, for example a server error or network connection problem.

js

const url = "notaurl";

async function initTransport(url) {
  try {
    // Initialize transport connection
    const transport = new WebTransport(url);

    // The connection can be used once ready fulfills
    await transport.ready;

    // ...
  } catch (error) {
    const msg = `Transport initialization failed.
                 Reason: ${error.message}.
                 Source: ${error.source}.
                 Error code: ${error.streamErrorCode}.`;
    console.log(msg);
  }
}
