Description

AWS SDK for JavaScript Pricing Client for Node.js, Browser and React Native.

The Amazon Web Services Price List API is a centralized and convenient way to programmatically query Amazon Web Services for services, products, and pricing information. The Amazon Web Services Price List uses standardized product attributes such as Location, Storage Class, and Operating System, and provides prices at the SKU level. You can use the Amazon Web Services Price List to do the following:

• Build cost control and scenario planning tools

• Reconcile billing data

• Forecast future spend for budgeting purposes

• Provide cost benefit analysis that compare your internal workloads with Amazon Web Services

Use GetServices without a service code to retrieve the service codes for all Amazon Web Services services, then GetServices with a service code to retrieve the attribute names for that service. After you have the service code and attribute names, you can use GetAttributeValues to see what values are available for an attribute. With the service code and an attribute name and value, you can use GetProducts to find specific products that you're interested in, such as an AmazonEC2 instance, with a Provisioned IOPS volumeType.

For more information, see Using the Amazon Web Services Price List API in the Billing User Guide.

Installing

To install this package, simply type add or install @aws-sdk/client-pricing using your favorite package manager:

• npm install @aws-sdk/client-pricing
• yarn add @aws-sdk/client-pricing
• pnpm add @aws-sdk/client-pricing

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the PricingClient and the commands you need, for example ListPriceListsCommand:

// ES5 example
const { PricingClient, ListPriceListsCommand } = require("@aws-sdk/client-pricing");

// ES6+ example
import { PricingClient, ListPriceListsCommand } from "@aws-sdk/client-pricing";

Usage

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.
• 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 PricingClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new ListPriceListsCommand(params);

Async/await

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.

Promises

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.
  });

Callbacks

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.
});

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

import * as AWS from "@aws-sdk/client-pricing";
const client = new AWS.Pricing({ region: "REGION" });

// async/await.
try {
  const data = await client.listPriceLists(params);
  // process data.
} catch (error) {
  // error handling.
}

// Promises.
client
  .listPriceLists(params)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  });

// callbacks.
client.listPriceLists(params, (err, data) => {
  // process err and data.
});

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 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;
   * }
   */
}
