In DSH (DeepSeek Harness) development, when Connection and Typert Gateway separately handle communication and business logic, building bidirectional service calls often requires an additional adapter layer. The the-binding-of-dsh plugin is designed to close this gap and enable the two to collaborate directly.

This is a DSH plugin maintained by CH4ACKO3. Its core value is enabling bidirectional service calls between DSH Connection and Typert Gateway, thereby simplifying the integration of multi-endpoint communication.

Core Capabilities

The plugin provides the following capabilities:

  • Targeted Calls: Supports targeted Host-to-Client calls to connected browser or Node peers.
  • Bidirectional Gateway: Implements symmetric Typert Gateway calls for bidirectional service interaction.
  • Lifecycle Management: Handles request association, cancellation, and the full connection lifecycle.
  • Transport Reuse: Typert RPC requests, results, and cancellation signals share the native events.host WebSocket; native multiplexed events and batched HTTP APIs retain their original transport methods.
  • Separation of Concerns: The plugin does not introduce parallel carriers. Connection is responsible for peer addressing and lifecycle management, while Typert Gateway is responsible for service descriptors, encoding/decoding, invocation, and error handling.

Installation and Activation

Install the plugin with the following command:

npm install the-binding-of-dsh

This plugin declares its DSH client entry point and Harmony patch in package.json, so it can be enabled directly as a standard DSH plugin. Before use, ensure your environment satisfies the following dependencies:

  • Node.js: 22.22.3 or later.
  • Harmony: 0.8.6 or later. Harmony automatically extracts browser module dependencies introduced by the Connection patch and automatically orders the Binding modules.

Typical Usage

Once the plugin is enabled, developers can establish a bidirectional channel between Connection and Typert Gateway. Through this mechanism, the Host side can issue requests directly to connected clients, while the Gateway can also perform service calls in both directions. Because the plugin reuses the native WebSocket and HTTP APIs, no additional transport-layer configuration is required.

Suitable Scenarios and Notes

This plugin is suitable for scenarios that require introducing bidirectional communication capabilities into an existing DSH architecture.

  • Environment Requirements: Node.js 22.22.3 or later, and Harmony 0.8.6 or later, are required.
  • Permissions and Security: The plugin runs with the permissions of the current DSH process. Be sure to review the source code and license before installation.
  • Architectural Responsibilities: During development, note that Connection is responsible for addressing and lifecycle management, while the Gateway is responsible for business logic (descriptors, encoding/decoding, and invocation). They collaborate through the Binding module.

By standardizing the bidirectional invocation process, this plugin reduces integration complexity in the DSH ecosystem. For more details, see the GitHub repository or the Skill Directory.
