Anthropic Bedrock TypeScript API Library

This library provides convenient access to the Anthropic Bedrock API.

For the non-Bedrock Anthropic API at api.anthropic.com, see @anthropic-ai/sdk.

Installation

npm install @anthropic-ai/bedrock-sdk

Usage

import { AnthropicBedrock } from '@anthropic-ai/bedrock-sdk';

// Note: this assumes you have configured AWS credentials in a way
// that the AWS Node SDK will recognise, typicaly a shared `~/.aws/credentials`
// file or `AWS_ACCESS_KEY_ID` & `AWS_SECRET_ACCESS_KEY` environment variables.
//
// https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/setting-credentials-node.html
const client = new AnthropicBedrock();

async function main() {
  const message = await client.messages.create({
    model: 'anthropic.claude-3-5-sonnet-20241022-v2:0',
    messages: [
      {
        role: 'user',
        content: 'Hello!',
      },
    ],
    max_tokens: 1024,
  });
  console.log(message);
}

main();

Custom Credential Provider (for non-Node environments)

For non-Node environments like Vercel Edge Runtime where the default AWS credential provider chain isn't available, you can provide a custom credential resolver:

import { AnthropicBedrock } from '@anthropic-ai/bedrock-sdk';

const customCredentialProvider = async () => {
  // Return an object that implements the AwsCredentialIdentityProvider interface
  return {
    accessKeyId: 'your-aws-access-key-id',
    secretAccessKey: 'your-aws-secret-access-key',
    sessionToken: 'your-aws-session-token', // Optional, if using temporary credentials
  };
};

const client = new AnthropicBedrock({
  awsRegion: 'us-east-1',
  providerChainResolver: async () => {
    return customCredentialProvider;
  },
});

For more details on how to use the SDK, see the README.md for the main Anthropic SDK which this library extends.
