@gensx/anthropic v0.2.2

@gensx/anthropic

A pre-wrapped version of the Anthropic SDK for GenSX. This package provides a simple way to use Anthropic's API with GenSX components.

Installation

npm install @gensx/anthropic

Usage

You can use this package in two ways:

1. Drop-in Replacement (Recommended)

Simply replace your Anthropic import with the GenSX version:

// Instead of:
// import { Anthropic } from '@anthropic-ai/sdk';

// Use:
import { Anthropic } from "@gensx/anthropic";

// Create a client as usual
const client = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
});

// All methods are automatically wrapped with GenSX functionality
const completion = await client.messages.create({
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: "Hello!" }],
  max_tokens: 1000,
});

// Use streaming
const stream = await client.messages.create({
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: "Hello!" }],
  max_tokens: 1000,
  stream: true,
});

2. Wrap an Existing Instance

If you already have an Anthropic instance, you can wrap it with GenSX functionality:

import { Anthropic } from "@anthropic-ai/sdk";
import { wrapAnthropic } from "@gensx/anthropic";

// Create your Anthropic instance as usual
const client = wrapAnthropic(
  new Anthropic({
    apiKey: process.env.ANTHROPIC_API_KEY,
  }),
);

// Now all methods are wrapped with GenSX functionality
const completion = await client.messages.create({
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: "Hello!" }],
  max_tokens: 1000,
});

3. Using with GenSX Components

You can also use the package with GenSX components:

import * as gensx from "@gensx/core";
import { AnthropicProvider, ChatCompletion } from "@gensx/anthropic";

const ChatBot = gensx.Component(async ({ userInput }) => {
  return (
    <AnthropicProvider apiKey={process.env.ANTHROPIC_API_KEY!}>
      <ChatCompletion
        system="You are a helpful assistant."
        messages={[{ role: "user", content: userInput }]}
        model="claude-sonnet-4-20250514"
        temperature={0.7}
      />
    </AnthropicProvider>
  );
});

// Use with streaming
const StreamingChat = gensx.Component(async ({ userInput }) => {
  return (
    <AnthropicProvider apiKey={process.env.ANTHROPIC_API_KEY!}>
      <ChatCompletion
        system="You are a helpful assistant."
        messages={[{ role: "user", content: userInput }]}
        stream={true}
        model="claude-sonnet-4-20250514"
      >
        {async (stream) => {
          for await (const token of stream) {
            process.stdout.write(token);
          }
        }}
      </ChatCompletion>
    </AnthropicProvider>
  );
});
