AWS SDK for JavaScript Ecs Client for Node.js, Browser and React Native
npm install @aws-sdk/client-ecsAWS SDK for JavaScript ECS Client for Node.js, Browser and React Native.
Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container
management service. It makes it easy to run, stop, and manage Docker containers. You can
host your cluster on a serverless infrastructure that's managed by Amazon ECS by
launching your services or tasks on Fargate. For more control, you can host your
tasks on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) or External
(on-premises) instances that you manage.
Amazon ECS makes it easy to launch and stop container-based applications with simple
API calls. This makes it easy to get the state of your cluster from a centralized
service, and gives you access to many familiar Amazon EC2 features.
You can use Amazon ECS to schedule the placement of containers across your cluster
based on your resource needs, isolation policies, and availability requirements. With
Amazon ECS, you don't need to operate your own cluster management and configuration
management systems. You also don't need to worry about scaling your management
infrastructure.
npm install @aws-sdk/client-ecsyarn add @aws-sdk/client-ecspnpm add @aws-sdk/client-ecsThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the ECSClient and
the commands you need, for example ListTasksCommand:
``js`
// ES5 example
const { ECSClient, ListTasksCommand } = require("@aws-sdk/client-ecs");
`ts`
// ES6+ example
import { ECSClient, ListTasksCommand } from "@aws-sdk/client-ecs";
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.destroy()
- If you are using a custom http handler, you may call to close open connections.
`js
// a client can be shared by different commands.
const client = new ECSClient({ region: "REGION" });
const params = { /* input parameters / };
const command = new ListTasksCommand(params);
`
#### Async/await
We recommend using 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
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,
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
`ts
import * as AWS from "@aws-sdk/client-ecs";
const client = new AWS.ECS({ region: "REGION" });
// async/await.
try {
const data = await client.listTasks(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listTasks(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listTasks(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).
`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;
* }
*/
}
