AWS SDK for JavaScript Budgets Client for Node.js, Browser and React Native.
Use the Amazon Web Services Budgets API to plan your service usage, service costs, and instance reservations. This API reference provides descriptions, syntax, and usage examples for each of the actions and data types for the Amazon Web Services Budgets feature.
Budgets provide you with a way to see the following information:
-
How close your plan is to your budgeted amount or to the free tier limits
-
Your usage-to-date, including how much you've used of your Reserved Instances (RIs)
-
Your current estimated charges from Amazon Web Services, and how much your predicted usage will accrue in charges by the end of the month
-
How much of your budget has been used
Amazon Web Services updates your budget status several times a day. Budgets track your unblended costs, subscriptions, refunds, and RIs. You can create the following types of budgets:
-
Cost budgets - Plan how much you want to spend on a service.
-
Usage budgets - Plan how much you want to use one or more services.
-
RI utilization budgets - Define a utilization threshold, and receive alerts when your RI usage falls below that threshold. This lets you see if your RIs are unused or under-utilized.
-
RI coverage budgets - Define a coverage threshold, and receive alerts when the number of your instance hours that are covered by RIs fall below that threshold. This lets you see how much of your instance usage is covered by a reservation.
Service Endpoint
The Amazon Web Services Budgets API provides the following endpoint:

To install the this package, simply type add or install @aws-sdk/client-budgets using your favorite package manager:
npm install @aws-sdk/client-budgetsyarn add @aws-sdk/client-budgetspnpm add @aws-sdk/client-budgets
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the BudgetsClient and
the commands you need, for example DescribeBudgetsCommand:
// ES5 example
const { BudgetsClient, DescribeBudgetsCommand } = require("@aws-sdk/client-budgets");// ES6+ example
import { BudgetsClient, DescribeBudgetsCommand } from "@aws-sdk/client-budgets";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 BudgetsClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new DescribeBudgetsCommand(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-budgets";
const client = new AWS.Budgets({ region: "REGION" });
// async/await.
try {
const data = await client.describeBudgets(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.describeBudgets(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.describeBudgets(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;
* }
