Description

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

This is the Proton Service API Reference. It provides descriptions, syntax and usage examples for each of the actions and data types for the Proton service.

The documentation for each action shows the Query API request parameters and the XML response.

Alternatively, you can use the Amazon Web Services CLI to access an API. For more information, see the Amazon Web Services Command Line Interface User Guide.

The Proton service is a two-pronged automation framework. Administrators create service templates to provide standardized infrastructure and deployment tooling for serverless and container based applications. Developers, in turn, select from the available service templates to automate their application or service deployments.

Because administrators define the infrastructure and tooling that Proton deploys and manages, they need permissions to use all of the listed API operations.

When developers select a specific infrastructure and tooling set, Proton deploys their applications. To monitor their applications that are running on Proton, developers need permissions to the service create, list, update and delete API operations and the service instance list and update API operations.

To learn more about Proton administration, see the Proton Administrator Guide.

To learn more about deploying serverless and containerized applications on Proton, see the Proton User Guide.

Ensuring Idempotency

When you make a mutating API request, the request typically returns a result before the asynchronous workflows of the operation are complete. Operations might also time out or encounter other server issues before they're complete, even if the request already returned a result. This might make it difficult to determine whether the request succeeded. Moreover, you might need to retry the request multiple times to ensure that the operation completes successfully. However, if the original request and the subsequent retries are successful, the operation occurs multiple times. This means that you might create more resources than you intended.

Idempotency ensures that an API request action completes no more than one time. With an idempotent request, if the original request action completes successfully, any subsequent retries complete successfully without performing any further actions. However, the result might contain updated information, such as the current creation status.

The following lists of APIs are grouped according to methods that ensure idempotency.

Idempotent create APIs with a client token

The API actions in this list support idempotency with the use of a client token. The corresponding Amazon Web Services CLI commands also support idempotency using a client token. A client token is a unique, case-sensitive string of up to 64 ASCII characters. To make an idempotent API request using one of these actions, specify a client token in the request. We recommend that you don't reuse the same client token for other API requests. If you don’t provide a client token for these APIs, a default client token is automatically provided by SDKs.

Given a request action that has succeeded:

If you retry the request using the same client token and the same parameters, the retry succeeds without performing any further actions other than returning the original resource detail data in the response.

If you retry the request using the same client token, but one or more of the parameters are different, the retry throws a ValidationException with an IdempotentParameterMismatch error.

Client tokens expire eight hours after a request is made. If you retry the request with the expired token, a new resource is created.

If the original resource is deleted and you retry the request, a new resource is created.

Idempotent create APIs with a client token:

• CreateEnvironmentTemplateVersion

• CreateServiceTemplateVersion

• CreateEnvironmentAccountConnection

Idempotent create APIs

Given a request action that has succeeded:

If you retry the request with an API from this group, and the original resource hasn't been modified, the retry succeeds without performing any further actions other than returning the original resource detail data in the response.

If the original resource has been modified, the retry throws a ConflictException.

If you retry with different input parameters, the retry throws a ValidationException with an IdempotentParameterMismatch error.

Idempotent create APIs:

• CreateEnvironmentTemplate

• CreateServiceTemplate

• CreateEnvironment

• CreateService

Idempotent delete APIs

Given a request action that has succeeded:

When you retry the request with an API from this group and the resource was deleted, its metadata is returned in the response.

If you retry and the resource doesn't exist, the response is empty.

In both cases, the retry succeeds.

Idempotent delete APIs:

• DeleteEnvironmentTemplate

• DeleteEnvironmentTemplateVersion

• DeleteServiceTemplate

• DeleteServiceTemplateVersion

• DeleteEnvironmentAccountConnection

Asynchronous idempotent delete APIs

Given a request action that has succeeded:

If you retry the request with an API from this group, if the original request delete operation status is DELETE_IN_PROGRESS, the retry returns the resource detail data in the response without performing any further actions.

If the original request delete operation is complete, a retry returns an empty response.

Asynchronous idempotent delete APIs:

• DeleteEnvironment

• DeleteService

Installing

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

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

Getting Started

Import

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

// ES5 example
const { ProtonClient, AcceptEnvironmentAccountConnectionCommand } = require("@aws-sdk/client-proton");

// ES6+ example
import { ProtonClient, AcceptEnvironmentAccountConnectionCommand } from "@aws-sdk/client-proton";

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 ProtonClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new AcceptEnvironmentAccountConnectionCommand(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-proton";
const client = new AWS.Proton({ region: "REGION" });

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

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

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