# TypeScript 

使用 @anthropic-ai/sdk 和 openai 的 Node 示例，涵盖流式响应。

[ 在 Claude 中提问](https://claude.ai/new?q=Read%20https%3A//aiprimetech.io/docs/sdks/typescript.md%20and%20answer%20questions%20about%20it.%20Start%20with%20a%20short%20summary.)   

## Anthropic SDK 

```
Copynpm install @anthropic-ai/sdk
```

```
Copyimport Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: process.env.CLAUDEAPIKEY!,
  baseURL: "https:">//aiprimetech.io",            // no /v1
});

const msg = await client.messages.create({
  model: "claude-sonnet-4-6",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Explain event loops briefly." }],
});

const block = msg.content[0];
if (block.type === "text") console.log(block.text);
```

content 是一个可辨识联合类型。请根据以下字段收窄类型： block.type === "text" 而不要盲目按索引访问——工具使用回复没有 .text 并且其值会是 undefined 在运行时。 

## 流式传输 

```
Copyconst stream = await client.messages.stream({
  model: "claude-sonnet-4-6",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Count to five." }],
});

for await (const event of stream) {
  if (event.type === "content_block_delta" && event.delta.type === "text_delta") {
    process.stdout.write(event.delta.text);
  }
}
const final = await stream.finalMessage();
console.log(final.usage);
```

## OpenAI SDK 

```
Copyimport OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.CLAUDEAPIKEY!,
  baseURL: "https:">//aiprimetech.io/v1",         // with /v1
});

const r = await client.chat.completions.create({
  model: "claude-sonnet-4-6",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(r.choices[0].message.content);
```

切勿在浏览器端代码中包含密钥。请从服务端调用网关，并向前端提供您自己的端点——打包产物中的任何内容都是公开的。
