AWS SDK for JavaScript ResourceGroups Client for Node.js, Browser and React Native.
Resource Groups lets you organize Amazon Web Services resources such as Amazon Elastic Compute Cloud instances, Amazon Relational Database Service databases, and Amazon Simple Storage Service buckets into groups using criteria that you define as tags. A resource group is a collection of resources that match the resource types specified in a query, and share one or more tags or portions of tags. You can create a group of resources based on their roles in your cloud infrastructure, lifecycle stages, regions, application layers, or virtually any criteria. Resource Groups enable you to automate management tasks, such as those in Amazon Web Services Systems Manager Automation documents, on tag-related resources in Amazon Web Services Systems Manager. Groups of tagged resources also let you quickly view a custom console in Amazon Web Services Systems Manager that shows Config compliance and other monitoring data about member resources.
To create a resource group, build a resource query, and specify tags that identify the criteria that members of the group have in common. Tags are key-value pairs.
For more information about Resource Groups, see the Resource Groups User Guide.
Resource Groups uses a REST-compliant API that you can use to perform the following types of operations.
-
Create, Read, Update, and Delete (CRUD) operations on resource groups and resource query entities
-
Applying, editing, and removing tags from resource groups
-
Resolving resource group member ARNs so they can be returned as search results
-
Getting data about resources that are members of a group
-
Searching Amazon Web Services resources based on a resource query
To install the this package, simply type add or install @aws-sdk/client-resource-groups using your favorite package manager:
npm install @aws-sdk/client-resource-groupsyarn add @aws-sdk/client-resource-groupspnpm add @aws-sdk/client-resource-groups
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the ResourceGroupsClient and
the commands you need, for example ListGroupsCommand:
// ES5 example
const { ResourceGroupsClient, ListGroupsCommand } = require("@aws-sdk/client-resource-groups");// ES6+ example
import { ResourceGroupsClient, ListGroupsCommand } from "@aws-sdk/client-resource-groups";To send a request, you:
- Initiate client with configuration (e.g. credentials, region).
- Initiate command with input parameters.
- Call
sendoperation 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 ResourceGroupsClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListGroupsCommand(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-resource-groups";
const client = new AWS.ResourceGroups({ region: "REGION" });
// async/await.
try {
const data = await client.listGroups(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listGroups(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listGroups(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;
* }
