@anthropic-ai/sdk 0.5.0

v0.5.0 – ⚠️ BREAKING, fully rewritten library

on Node.js NPM

  // Import "Anthropic" instead of "Client":
- import { Client, HUMAN_PROMPT, AI_PROMPT } from '@anthropic-ai/sdk';
+ import Anthropic, { HUMAN_PROMPT, AI_PROMPT } from '@anthropic-ai/sdk';

  // Instantiate with "apiKey" as an object property:
- const client = new Client(apiKey);
+ const client = new Anthropic({ apiKey });
  // or, simply provide an ANTHROPIC_API_KEY environment variable:
+ const client = new Anthropic();

  async function main() {
    // Request & response types are the same as before, but better-typed.
    const params = {
      prompt: `${HUMAN_PROMPT} How many toes do dogs have?${AI_PROMPT}`,
      max_tokens_to_sample: 200,
      model: "claude-1",
    };

    // Instead of "client.complete()", you now call "client.completions.create()":
-   await client.complete(params);
+   await client.completions.create(params);

    // Streaming requests now use async iterators instead of callbacks:
-   client.completeStream(params, {
-     onUpdate: (completion) => {
-       console.log(completion.completion); // full text
-     },
-   });
+   const stream = await client.completions.create({ ...params, stream: true });
+   for await (const completion of stream) {
+     console.log(completion.completion); // incremental text
+   }

    // And, since this library uses `Anthropic-Version: 2023-06-01`,
    // completion streams are now incremental diffs of text
    // rather than sending the whole message every time:
    let text = '';
-   await client.completeStream(params, {
-     onUpdate: (completion) => {
-       const diff = completion.completion.replace(text, "");
-       text = completion.completion;
-       process.stdout.write(diff);
-     },
-   });
+   const stream = await client.completions.create({ ...params, stream: true });
+   for await (const completion of stream) {
+     const diff = completion.completion;
+     text += diff;
+     process.stdout.write(diff);
+   }
    console.log('Done; final text is:')
    console.log(text)
  }
  main();
