Describes the API operations for running inference using Amazon Bedrock models.
## Installing To install this package, simply type add or install @aws-sdk/client-bedrock-runtime using your favorite package manager: - `npm install @aws-sdk/client-bedrock-runtime` - `yarn add @aws-sdk/client-bedrock-runtime` - `pnpm add @aws-sdk/client-bedrock-runtime` ## Getting Started ### Import The AWS SDK is modulized by clients and commands. To send a request, you only need to import the `BedrockRuntimeClient` and the commands you need, for example `ListAsyncInvokesCommand`: ```js // ES5 example const { BedrockRuntimeClient, ListAsyncInvokesCommand } = require("@aws-sdk/client-bedrock-runtime"); ``` ```ts // ES6+ example import { BedrockRuntimeClient, ListAsyncInvokesCommand } from "@aws-sdk/client-bedrock-runtime"; ``` ### Usage To send a request, you: - Initiate client with configuration (e.g. credentials, region). - Initiate command with input parameters. - Call `send` operation on client with command object as input. - If you are using a custom http handler, you may call `destroy()` to close open connections. ```js // a client can be shared by different commands. const client = new BedrockRuntimeClient({ region: "REGION" }); const params = { /** input parameters */ }; const command = new ListAsyncInvokesCommand(params); ``` #### Async/await We recommend using [await](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/await) operator to wait for the promise returned by send operation as follows: ```js // async/await. try { const data = await client.send(command); // process data. } catch (error) { // error handling. } finally { // finally. } ``` Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks. #### Promises You can also use [Promise chaining](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises#chaining) to execute send operation. ```js client.send(command).then( (data) => { // process data. }, (error) => { // error handling. } ); ``` Promises can also be called using `.catch()` and `.finally()` as follows: ```js client .send(command) .then((data) => { // process data. }) .catch((error) => { // error handling. }) .finally(() => { // finally. }); ``` #### Callbacks We do not recommend using callbacks because of [callback hell](http://callbackhell.com/), but they are supported by the send operation. ```js // callbacks. client.send(command, (err, data) => { // process err and data. }); ``` #### v2 compatible style The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on [modular packages in AWS SDK for JavaScript](https://aws.amazon.com/blogs/developer/modular-packages-in-aws-sdk-for-javascript/) ```ts import * as AWS from "@aws-sdk/client-bedrock-runtime"; const client = new AWS.BedrockRuntime({ region: "REGION" }); // async/await. try { const data = await client.listAsyncInvokes(params); // process data. } catch (error) { // error handling. } // Promises. client .listAsyncInvokes(params) .then((data) => { // process data. }) .catch((error) => { // error handling. }); // callbacks. client.listAsyncInvokes(params, (err, data) => { // process err and data. }); ``` ### Troubleshooting When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id). ```js try { const data = await client.send(command); // process data. } catch (error) { const { requestId, cfId, extendedRequestId } = error.$metadata; console.log({ requestId, cfId, extendedRequestId }); /** * The keys within exceptions are also parsed. * You can access them by specifying exception names: * if (error.name === 'SomeServiceException') { * const value = error.specialKeyInException; * } */ } ``` ## Getting Help Please use these community resources for getting help.
