@open-harness/server

Server utilities for Open Harness.

Status: Minimal Package

Most v0.2.0 server code was deleted as part of the v0.3.0 migration. This package now provides only essential middleware utilities.

Current Exports

import { createHealthRoute, corsMiddleware, errorHandler } from "@open-harness/server";

createHealthRoute()

Creates a Hono health check route:

import { Hono } from "hono";
import { createHealthRoute } from "@open-harness/server";

const app = new Hono();
app.route("/health", createHealthRoute());
// GET /health returns { status: "ok" }

corsMiddleware

CORS middleware for Hono:

import { corsMiddleware } from "@open-harness/server";

app.use("*", corsMiddleware);

errorHandler

Error handling middleware:

import { errorHandler } from "@open-harness/server";

app.onError(errorHandler);

Building v0.3.0 Servers

For v0.3.0, build custom Hono routes that consume Harness signals:

import { Hono } from "hono";
import { ClaudeHarness, createSignal } from "@open-harness/core";

const app = new Hono();

app.post("/chat", async (c) => {
  const harness = new ClaudeHarness();
  const input = await c.req.json();

  const signals: Signal[] = [];
  for await (const signal of harness.run(input, { signal: c.req.raw.signal })) {
    signals.push(signal);
  }

  return c.json({ signals });
});

Deleted Exports (v0.2.0)

The following were removed in v0.3.0:

• createChatRoute, createCommandsRoute, createEventsRoute - Old API routes
• createLocalAIKitTransport, WebSocketTransport - Old transports
• createWorkflow, runFlow, registerStandardNodes - Old workflow utilities
• Claude agent/node types - Use ClaudeHarness from @open-harness/core
