@aws-sdk/client-rekognition is an AWS SDK for JavaScript package that provides a client for Amazon Rekognition, a service that makes it easy to add image and video analysis to your applications. The package allows you to perform a variety of tasks such as object detection, facial analysis, and text recognition.

What are @aws-sdk/client-rekognition's main functionalities?

Detecting Labels in an Image

This feature allows you to detect objects, scenes, and concepts in an image stored in an S3 bucket. The code sample demonstrates how to use the DetectLabelsCommand to get labels for an image.

const { RekognitionClient, DetectLabelsCommand } = require('@aws-sdk/client-rekognition');

const client = new RekognitionClient({ region: 'us-west-2' });
const params = {
  Image: {
    S3Object: {
      Bucket: 'example-bucket',
      Name: 'example.jpg'
    }
  },
  MaxLabels: 10
};

const run = async () => {
  try {
    const data = await client.send(new DetectLabelsCommand(params));
    console.log('Labels detected:', data.Labels);
  } catch (err) {
    console.error('Error:', err);
  }
};

run();

Facial Analysis

This feature allows you to analyze faces in an image to detect attributes such as age range, emotions, and facial landmarks. The code sample demonstrates how to use the DetectFacesCommand to get detailed facial analysis.

const { RekognitionClient, DetectFacesCommand } = require('@aws-sdk/client-rekognition');

const client = new RekognitionClient({ region: 'us-west-2' });
const params = {
  Image: {
    S3Object: {
      Bucket: 'example-bucket',
      Name: 'example.jpg'
    }
  },
  Attributes: ['ALL']
};

const run = async () => {
  try {
    const data = await client.send(new DetectFacesCommand(params));
    console.log('Face details:', data.FaceDetails);
  } catch (err) {
    console.error('Error:', err);
  }
};

run();

Text Detection in Images

This feature allows you to detect and recognize text within an image. The code sample demonstrates how to use the DetectTextCommand to extract text from an image stored in an S3 bucket.

const { RekognitionClient, DetectTextCommand } = require('@aws-sdk/client-rekognition');

const client = new RekognitionClient({ region: 'us-west-2' });
const params = {
  Image: {
    S3Object: {
      Bucket: 'example-bucket',
      Name: 'example.jpg'
    }
  }
};

const run = async () => {
  try {
    const data = await client.send(new DetectTextCommand(params));
    console.log('Detected text:', data.TextDetections);
  } catch (err) {
    console.error('Error:', err);
  }
};

run();

Installing

To install the this package, simply type add or install @aws-sdk/client-rekognition using your favorite package manager:

npm install @aws-sdk/client-rekognition
yarn add @aws-sdk/client-rekognition
pnpm add @aws-sdk/client-rekognition

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the RekognitionClient and the commands you need, for example ListCollectionsCommand:

// ES5 example
const { RekognitionClient, ListCollectionsCommand } = require("@aws-sdk/client-rekognition");

// ES6+ example
import { RekognitionClient, ListCollectionsCommand } from "@aws-sdk/client-rekognition";

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.

// a client can be shared by different commands.
const client = new RekognitionClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new ListCollectionsCommand(params);

Async/await

We recommend using await operator to wait for the promise returned by send operation as follows:

// 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 to execute send operation.

client.send(command).then(
  (data) => {
    // process data.
  },
  (error) => {
    // error handling.
  }
);

Promises can also be called using .catch() and .finally() as follows:

client
  .send(command)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  })
  .finally(() => {
    // finally.
  });

Callbacks

We do not recommend using callbacks because of callback hell, but they are supported by the send operation.

// 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

import * as AWS from "@aws-sdk/client-rekognition";
const client = new AWS.Rekognition({ region: "REGION" });

// async/await.
try {
  const data = await client.listCollections(params);
  // process data.
} catch (error) {
  // error handling.
}

// Promises.
client
  .listCollections(params)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  });

// callbacks.
client.listCollections(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).

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;
   * }
   */
}
