AWS SDK for JavaScript Compute Optimizer Client for Node.js, Browser and React Native
AWS SDK for JavaScript ComputeOptimizer Client for Node.js, Browser and React Native.
Compute Optimizer is a service that analyzes the configuration and utilization metrics of your Amazon Web Services compute resources, such as Amazon EC2 instances, Amazon EC2 Auto Scaling groups, Lambda functions, Amazon EBS volumes, and Amazon ECS services on Fargate. It reports whether your resources are optimal, and generates optimization recommendations to reduce the cost and improve the performance of your workloads. Compute Optimizer also provides recent utilization metric data, in addition to projected utilization metric data for the recommendations, which you can use to evaluate which recommendation provides the best price-performance trade-off. The analysis of your usage patterns can help you decide when to move or resize your running resources, and still meet your performance and capacity requirements. For more information about Compute Optimizer, including the required permissions to use the service, see the Compute Optimizer User Guide.
To install this package, simply type add or install @aws-sdk/client-compute-optimizer using your favorite package manager:
npm install @aws-sdk/client-compute-optimizeryarn add @aws-sdk/client-compute-optimizerpnpm add @aws-sdk/client-compute-optimizerThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the ComputeOptimizerClient and
the commands you need, for example GetEnrollmentStatusCommand:
// ES5 example
const { ComputeOptimizerClient, GetEnrollmentStatusCommand } = require("@aws-sdk/client-compute-optimizer");
// ES6+ example
import { ComputeOptimizerClient, GetEnrollmentStatusCommand } from "@aws-sdk/client-compute-optimizer";
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 ComputeOptimizerClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new GetEnrollmentStatusCommand(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-compute-optimizer";
const client = new AWS.ComputeOptimizer({ region: "REGION" });
// async/await.
try {
const data = await client.getEnrollmentStatus(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.getEnrollmentStatus(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.getEnrollmentStatus(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;
* }
*/
}
