OpenAI Agents SDK Adds TypeScript Support

Overview

OpenAI's official Agent SDK has announced TypeScript support, bringing production-grade agent development capabilities to frontend and full-stack developers. This update fills the gap in the JavaScript/TypeScript ecosystem for OpenAI Agents SDK, enabling developers to build cross-platform AI agent applications using a unified API.

Core Features

1. Unified API Design

The TypeScript SDK maintains consistent API design with the Python version, reducing learning curve:

import { Agent } from 'openai-agents';

const assistant = new Agent({
  name: 'Code Assistant',
  instructions: 'You are a helpful coding assistant.',
  model: 'gpt-4o',
  tools: [
    {
      type: 'function',
      name: 'search_codebase',
      description: 'Search the codebase for relevant files',
      parameters: {
        type: 'object',
        properties: {
          query: { type: 'string', description: 'Search query' }
        },
        required: ['query']
      }
    }
  ]
});

2. Type Safety

Fully leverage TypeScript's type system:

Complete type inference for tool parameters and return values
Type safety for state objects
Auto-completion and error checking

3. Next.js Integration

Next.js-optimized integration:

// app/api/agent/route.ts
import { NextResponse } from 'next/server';
import { Agent } from 'openai-agents';

export async function POST(req: Request) {
  const agent = new Agent({ /* ... */ });
  const result = await agent.run('Explain this code');
  return NextResponse.json({ result });
}

4. Streaming Responses

Support for Server-Sent Events (SSE) streaming:

const stream = agent.runStream('Analyze this codebase');
for await (const event of stream) {
  console.log(event.delta);
}
