ACM PCA Client - AWS SDK for JavaScript v3

@aws-sdk/client-acm-pca

NPM version NPM downloads

Description

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

This is the Private Certificate Authority (PCA) API Reference. It provides descriptions, syntax, and usage examples for each of the actions and data types involved in creating and managing a private certificate authority (CA) for your organization.

The documentation for each action shows the API request parameters and the JSON response. Alternatively, you can use one of the Amazon Web Services SDKs to access an API that is tailored to the programming language or platform that you prefer. For more information, see Amazon Web Services SDKs.

Each ACM Private CA API operation has a quota that determines the number of times the operation can be called per second. ACM Private CA throttles API requests at different rates depending on the operation. Throttling means that ACM Private CA rejects an otherwise valid request because the request exceeds the operation's quota for the number of requests per second. When a request is throttled, ACM Private CA returns a ThrottlingException error. ACM Private CA does not guarantee a minimum request rate for APIs.

To see an up-to-date list of your ACM Private CA quotas, or to request a quota increase, log into your Amazon Web Services account and visit the Service Quotas console.

Installing

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

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

Getting Started

Import

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

// ES5 example
const { ACMPCAClient, CreateCertificateAuthorityCommand } = require("@aws-sdk/client-acm-pca");
// ES6+ example
import { ACMPCAClient, CreateCertificateAuthorityCommand } from "@aws-sdk/client-acm-pca";

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 ACMPCAClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new CreateCertificateAuthorityCommand(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-acm-pca";
const client = new AWS.ACMPCA({ region: "REGION" });

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

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

// callbacks.
client.createCertificateAuthority(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;
   * }
   */
}
