AWS SDK for JavaScript Ecr Client for Node.js, Browser and React Native
@aws-sdk/client-ecr is an AWS SDK for JavaScript package that allows developers to interact with Amazon Elastic Container Registry (ECR). ECR is a fully managed Docker container registry that makes it easy to store, manage, and deploy Docker container images.
Create Repository
This feature allows you to create a new repository in Amazon ECR. The code sample demonstrates how to create a repository named 'my-repo' using the ECRClient and CreateRepositoryCommand.
const { ECRClient, CreateRepositoryCommand } = require('@aws-sdk/client-ecr');
const client = new ECRClient({ region: 'us-west-2' });
const command = new CreateRepositoryCommand({ repositoryName: 'my-repo' });
client.send(command).then(
(data) => console.log(data),
(error) => console.error(error)
);List Repositories
This feature allows you to list all repositories in your Amazon ECR. The code sample demonstrates how to use the DescribeRepositoriesCommand to retrieve and log the list of repositories.
const { ECRClient, DescribeRepositoriesCommand } = require('@aws-sdk/client-ecr');
const client = new ECRClient({ region: 'us-west-2' });
const command = new DescribeRepositoriesCommand({});
client.send(command).then(
(data) => console.log(data.repositories),
(error) => console.error(error)
);Delete Repository
This feature allows you to delete a repository from Amazon ECR. The code sample demonstrates how to delete a repository named 'my-repo' using the DeleteRepositoryCommand.
const { ECRClient, DeleteRepositoryCommand } = require('@aws-sdk/client-ecr');
const client = new ECRClient({ region: 'us-west-2' });
const command = new DeleteRepositoryCommand({ repositoryName: 'my-repo', force: true });
client.send(command).then(
(data) => console.log(data),
(error) => console.error(error)
);Push Image
This feature allows you to push a Docker image to an Amazon ECR repository. The code sample demonstrates how to get an authorization token, log in to the ECR registry using Docker, and push an image named 'my-repo:latest'.
const { ECRClient, GetAuthorizationTokenCommand } = require('@aws-sdk/client-ecr');
const { exec } = require('child_process');
const client = new ECRClient({ region: 'us-west-2' });
const command = new GetAuthorizationTokenCommand({});
client.send(command).then(
(data) => {
const authData = data.authorizationData[0];
const authToken = Buffer.from(authData.authorizationToken, 'base64').toString('utf-8').split(':')[1];
const proxyEndpoint = authData.proxyEndpoint;
exec(`docker login -u AWS -p ${authToken} ${proxyEndpoint}`, (err, stdout, stderr) => {
if (err) {
console.error('Login failed:', stderr);
return;
}
console.log('Login successful:', stdout);
exec('docker push my-repo:latest', (err, stdout, stderr) => {
if (err) {
console.error('Push failed:', stderr);
return;
}
console.log('Push successful:', stdout);
});
});
},
(error) => console.error(error)
);Dockerode is a Node.js module that provides a Docker Remote API client. It allows you to manage Docker containers, images, and networks. Unlike @aws-sdk/client-ecr, which is specific to Amazon ECR, Dockerode provides a more general interface for interacting with Docker.
Node-docker-api is another Node.js client for the Docker Remote API. It offers a promise-based interface for managing Docker containers, images, volumes, and networks. Similar to Dockerode, it is not specific to Amazon ECR but provides broader Docker management capabilities.
The aws-sdk package is the older, monolithic AWS SDK for JavaScript. It includes support for all AWS services, including ECR. However, it is larger and less modular compared to the newer, service-specific packages like @aws-sdk/client-ecr.

Amazon Elastic Container Registry
Amazon Elastic Container Registry (Amazon ECR) is a managed container image registry service. Customers can use the familiar Docker CLI, or their preferred client, to push, pull, and manage images. Amazon ECR provides a secure, scalable, and reliable registry for your Docker or Open Container Initiative (OCI) images. Amazon ECR supports private repositories with resource-based permissions using IAM so that specific users or Amazon EC2 instances can access repositories and images.
Amazon ECR has service endpoints in each supported Region. For more information, see Amazon ECR endpoints in the Amazon Web Services General Reference.
To install this package, simply type add or install @aws-sdk/client-ecr using your favorite package manager:
npm install @aws-sdk/client-ecryarn add @aws-sdk/client-ecrpnpm add @aws-sdk/client-ecrThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the ECRClient and
the commands you need, for example ListImagesCommand:
// ES5 example
const { ECRClient, ListImagesCommand } = require("@aws-sdk/client-ecr");
// ES6+ example
import { ECRClient, ListImagesCommand } from "@aws-sdk/client-ecr";
To send a request, you:
send operation on client with command object as input.destroy() to close open connections.// a client can be shared by different commands.
const client = new ECRClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListImagesCommand(params);
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.
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.
});
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.
});
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-ecr";
const client = new AWS.ECR({ region: "REGION" });
// async/await.
try {
const data = await client.listImages(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listImages(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listImages(params, (err, data) => {
// process err and data.
});
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;
* }
*/
}
