Description

AWS Auto Scaling

Use AWS Auto Scaling to quickly discover all the scalable AWS resources for your application and configure dynamic scaling and predictive scaling for your resources using scaling plans. Use this service in conjunction with the Amazon EC2 Auto Scaling, Application Auto Scaling, Amazon CloudWatch, and AWS CloudFormation services.

Currently, predictive scaling is only available for Amazon EC2 Auto Scaling groups.

For more information about AWS Auto Scaling, including information about granting IAM users required permissions for AWS Auto Scaling actions, see the AWS Auto Scaling User Guide.

Installing

To install the this package using NPM, simply type the following into a terminal window:

npm install @aws-sdk/client-auto-scaling-plans-node

Getting Started

Import

The AWS SDK is modulized by clients and commands in CommonJS modules. To send a request, you only need to import the client(AutoScalingPlansClient) and the commands you need, for example CreateScalingPlanCommand:

//JavaScript
const {
  AutoScalingPlansClient
} = require("@aws-sdk/client-auto-scaling-plans-node/AutoScalingPlansClient");
const {
  CreateScalingPlanCommand
} = require("@aws-sdk/client-auto-scaling-plans-node/commands/CreateScalingPlanCommand");

//TypeScript
import { AutoScalingPlansClient } from "@aws-sdk/client-auto-scaling-plans-node/AutoScalingPlansClient";
import { CreateScalingPlanCommand } from "@aws-sdk/client-auto-scaling-plans-node/commands/CreateScalingPlanCommand";

Usage

To send a request, you:

Initiate client with configuration (e.g. credentials, region). For more information you can refer to the API reference.
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.

const autoScalingPlans = new AutoScalingPlansClient({region: 'region'});
//clients can be shared by different commands
const params = {
  ScalingPlanName: /**a string value*/,
  ApplicationSource: { /**an object specifying ApplicationSource*/ },
  ScalingInstructions: [ /**a list of structure*/ ],
};
const createScalingPlanCommand = new CreateScalingPlanCommand(params);
autoScalingPlans.send(createScalingPlanCommand).then(data => {
    // do something
}).catch(error => {
    // error handling
})

In addition to using promises, there are 2 other ways to send a request:

// async/await
try {
  const data = await autoScalingPlans.send(createScalingPlanCommand);
  // do something
} catch (error) {
  // error handling
}

// callback
autoScalingPlans.send(createScalingPlanCommand, (err, data) => {
  //do something
});

The SDK can also send requests using the simplified callback style from version 2 of the SDK.

import * as AWS from "@aws-sdk/@aws-sdk/client-auto-scaling-plans-node/AutoScalingPlans";
const autoScalingPlans = new AWS.AutoScalingPlans({ region: "region" });
autoScalingPlans.createScalingPlan(params, (err, data) => {
  //do something
});

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 autoScalingPlans.send(createScalingPlanCommand);
  // do something
} catch (error) {
  const metadata = error.$metadata;
  console.log(
    `requestId: ${metadata.requestId}
cfId: ${metadata.cfId}
extendedRequestId: ${metadata.extendedRequestId}`
  );
  /*
The keys within exceptions are also parsed. You can access them by specifying exception names:
    if(error.name === 'SomeServiceException') {
        const value = error.specialKeyInException;
    }
*/
}
