Description

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

Introduction

The Amazon Interactive Video Service (IVS) API is REST compatible, using a standard HTTP
API and an Amazon Web Services EventBridge event stream for responses. JSON is used for both
requests and responses, including errors.

The API is an Amazon Web Services regional service. For a list of supported regions and
Amazon IVS HTTPS service endpoints, see the Amazon IVS page in the
Amazon Web Services General Reference.

All API request parameters and URLs are case sensitive.

For a summary of notable documentation changes in each release, see Document
History.

Key Concepts

• 
  

  
  Channel — Stores configuration data related to your live stream. You first create a channel and then use the channel’s stream key to start your live stream.

  
  


• 
  

  
  Stream key — An identifier assigned by Amazon IVS when you create a channel, which is then used to authorize streaming.
  Treat the stream key like a secret, since it allows anyone to stream to the channel.
  
  

  
  


• 
  

  
  Playback key pair — Video playback may be restricted using playback-authorization tokens, which use public-key encryption. A playback key pair is the public-private pair of keys used to sign and validate the playback-authorization token.

  
  


• 
  

  
  Recording configuration — Stores configuration related to recording a live stream and where to store the recorded content. Multiple channels can reference the same recording configuration.

  
  


• 
  

  
  Playback restriction policy — Restricts playback by countries and/or origin sites.

Tagging

A tag is a metadata label that you assign to an Amazon Web Services
resource. A tag comprises a key and a value, both
set by you. For example, you might set a tag as topic:nature to label a
particular video category. See Best practices and strategies in Tagging Amazon Web Services Resources and Tag Editor for details, including restrictions that apply to tags and "Tag naming limits and requirements"; Amazon IVS has no service-specific constraints beyond what is documented
there.

Tags can help you identify and organize your Amazon Web Services resources. For example,
you can use the same tag for different resources to indicate that they are related. You can
also use tags to manage access (see Access Tags).

The Amazon IVS API has these tag-related operations: TagResource, UntagResource, and ListTagsForResource. The following
resources support tagging: Channels, Stream Keys, Playback Key Pairs, and Recording
Configurations.

At most 50 tags can be applied to a resource.

Authentication versus Authorization

Note the differences between these concepts:

• 
  

  
  Authentication is about verifying identity. You need to be
  authenticated to sign Amazon IVS API requests.

  
  


• 
  

  
  Authorization is about granting permissions. Your IAM roles need to have permissions for Amazon IVS API requests. In addition,
  authorization is needed to view Amazon IVS private channels.
  (Private channels are channels that are enabled for "playback authorization.")

  
  

Authentication

All Amazon IVS API requests must be authenticated with a signature. The Amazon Web Services
Command-Line Interface (CLI) and Amazon IVS Player SDKs take care of signing the underlying
API calls for you. However, if your application calls the Amazon IVS API directly, it’s your
responsibility to sign the requests.

You generate a signature using valid Amazon Web Services credentials that have permission
to perform the requested action. For example, you must sign PutMetadata requests with a
signature generated from a user account that has the ivs:PutMetadata
permission.

For more information:

• 
  

  Authentication and generating signatures — See Authenticating Requests
  (Amazon Web Services Signature Version 4) in the Amazon Web Services
  General Reference.

  
  


• 
  

  Managing Amazon IVS permissions — See Identity and Access Management on
  the Security page of the Amazon IVS User Guide.

  
  

Amazon Resource Names (ARNs)

ARNs uniquely identify AWS resources. An ARN is required when you need to specify a
resource unambiguously across all of AWS, such as in IAM policies and API
calls. For more information, see Amazon
Resource Names in the AWS General Reference.

Installing

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

Getting Started

$3

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

``js
// ES5 example
const { IvsClient, ListStreamsCommand } = require("@aws-sdk/client-ivs");
`

`ts
// ES6+ example
import { IvsClient, ListStreamsCommand } from "@aws-sdk/client-ivs";
`

$3

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.

`js
// a client can be shared by different commands.
const client = new IvsClient({ region: "REGION" });

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

#### Async/await

We recommend using await
operator to wait for the promise returned by send operation as follows:

`js
// 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.

`js
client.send(command).then(
(data) => {
// process data.
},
(error) => {
// error handling.
}
);
`

Promises can also be called using .catch() and .finally() as follows:

`js
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.

`js
// 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

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

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

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

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

$3

When the service returns an exception, the error will include the exception information,
as well as response metadata (e.g. request id).

`js
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;
* }
*/
}
`
