README.md

Amazon Bedrock Runtime code examples for the SDK for JavaScript (v3)

Overview

Shows how to use the AWS SDK for JavaScript (v3) to work with Amazon Bedrock Runtime.

Amazon Bedrock Runtime is a fully managed service that makes it easy to use foundation models from third-party providers and Amazon.

⚠ Important

  • Running this code might result in charges to your AWS account. For more details, see AWS Pricing and Free Tier.
  • Running the tests might result in charges to your AWS account.
  • We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
  • This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Code examples

Prerequisites

For prerequisites, see the README in the javascriptv3 folder.

⚠ You must request access to a model before you can use it. If you try to use the model (with the API or console) before you have requested access to it, you will receive an error message. For more information, see Model access.

Get started

Scenarios

Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Amazon Nova

Amazon Nova Canvas

Amazon Titan Text

Anthropic Claude

Cohere Command

Meta Llama

Mistral AI

Run the examples

Instructions

Note: All code examples are written in ECMAscript 6 (ES6). For guidelines on converting to CommonJS, see JavaScript ES6/CommonJS syntax.

Run a single action

node ./actions/<fileName>

Run a scenario

Most scenarios can be run with the following command:

node ./scenarios/<fileName>

Run with options

Some actions and scenarios can be run with options from the command line:

node ./scenarios/<fileName> --option1 --option2

util.parseArgs is used to configure these options. For the specific options available to each script, see the parseArgs usage for that file.

Hello Amazon Bedrock Runtime

This example shows you how to get started using Amazon Bedrock Runtime.

node ./hello.js

Invoke multiple foundation models on Amazon Bedrock

This example shows you how to prepare and send a prompt to a variety of large-language models (LLMs) on Amazon Bedrock

Tool use with the Converse API

This example shows you how to build a typical interaction between an application, a generative AI model, and connected tools or APIs to mediate interactions between the AI and the outside world. It uses the example of connecting an external weather API to the AI model so it can provide real-time weather information based on user input.

Tests

⚠ Running tests might result in charges to your AWS account.

To find instructions for running these tests, see the README in the javascriptv3 folder.
