5.0.0

Changed

• BREAKING: Chunk large port stream messages into smaller frames by default (#68)
  • By default, ExtensionPortStream will send messages in 64MB chunks on Chromium-based browsers. When this mode is used the receiving end must also use ExtensionPortStream in its default mode:

    import { ExtensionPortStream } from "extension-port-stream";
    
    extension.runtime.onConnect.addListener(connectRemote);
    const portStream = new ExtensionPortStream(remotePort, {
      chunkSize: 0, // disable chunking
    });
    
    // Enjoy!

  • To disable chunking set the chunkSize option to 0. This will make the transport
    mostly backwards compatible with v4:

    import { ExtensionPortStream } from "extension-port-stream";
    
    extension.runtime.onConnect.addListener(connectRemote);
    const portStream = new ExtensionPortStream(remotePort, {
      chunkSize: 0, // disable chunking
    });
    
    // Enjoy!

  • message-too-large is emitted when a message is too large to send in a single postMessage call and needs to be chunked. This event is only emitted when chunking is enabled (default).
• BREAKING: Node.js-style Buffer messages are no longer supported (#68)
