Get started in three steps

Implement HAIP in your application with this quick guide.
Link to the examples in the repo.

​
📦 Install Packages

# Install SDK
npm install @haip/sdk

# Install Server
npm install @haip/server

# Install Types
npm install @types/haip

# Install CLI (optional)
npm install -g @haip/cli

​
Step 1: Create Server

Save this in server.js 
import { createPermissionMap, HAIPServer, HAIPTool } from "@haip/server";
import {
  HAIPEventType,
  HAIPMessage,
  HAIPSessionTransaction,
  HAIPToolSchema,
} from "haip";
import OpenAI from "openai";

const server = new HAIPServer({
  port: 8080,
  host: "0.0.0.0",
  jwtSecret: "CHANGE_THIS_TO_A_SECRET_STRING",
  enableCORS: true,
  enableLogging: true,
  flowControl: {
    enabled: true,
    minCredits: 100,
    maxCredits: 10000,
    creditThreshold: 200,
    backPressureThreshold: 0.8,
    adaptiveAdjustment: true,
  },
});

server.authenticate((req) => {
  // Here you should validate your with your auth system
  // Hardcoded check here
  if (req.token === "Bearer TOKEN") {
    return {
      id: "user123",
      permissions: createPermissionMap({ MESSAGE: ["*"] }),
      credits: 1000,
    };
  }
  return null;
});

server.start();

​
Step 2: Create client

Save this in client.js 
import { createHAIPClient } from "@haip/sdk";

async function main() {
  const client = createHAIPClient({
    url: "ws://localhost:8080",
  });

  client.authenticate(() => {
    // You should send a token here.
    return {
      token: "Bearer TOKEN",
    };
  });

  try {
    await client.connect();

    const transaction = await client.startTransaction("echo", {});

    transaction.on("message", (message: any) => {
      console.log("🤖 Agent:", message.payload);
    });

    console.log("✅ Sending to transaction:", "Hello! Can you echo this?");
    transaction.sendTextMessage("Hello! Can you echo this?");
  } catch (error) {
    console.error("Error:", error);
    await client.disconnect();
  }
}

main();

​
Step 3: Run Locally

In the client 
node server.js
node client.js
You should see something like this: 
> @haip/sdk@1.0.1 example
> ts-node ./example/test-client.ts

[HAIP] Transport connecting...
[HAIP] Handshake sent

✅ Sending to transaction: Hello! Can you echo this?
🤖 Agent: Hello! Can you echo this?

​
Step 4: Connecting with the CLI Tool

Now run (assumig you are running this locally on localhost:8080) 
haip chat --tool echo
You can also use the echo tool: 
✔ Transaction started...
You: Hello This is me
🤖 Agent: Hello This is me

Authentication

Secure your connections with JWT tokens and proper validation.

Tool Integration

Enable agents to call external tools and APIs.

Flow Control

Manage back-pressure and prevent system overload.

Error Handling

Implement robust error handling and recovery.
