What is @aws-sdk/eventstream-serde-universal?
@aws-sdk/eventstream-serde-universal is a package within the AWS SDK for JavaScript that provides serialization and deserialization of event streams. This is particularly useful for handling streaming data in AWS services like AWS Transcribe, AWS Kinesis, and others that use event streams.
What are @aws-sdk/eventstream-serde-universal's main functionalities?
Serialization of Event Streams
This feature allows you to serialize an event stream into a format that can be transmitted over the network. The code sample demonstrates how to create an instance of EventStreamMarshaller and serialize an event.
const { EventStreamMarshaller } = require('@aws-sdk/eventstream-serde-universal');
const marshaller = new EventStreamMarshaller();
const event = { eventType: 'example', data: 'sample data' };
const serializedEvent = marshaller.marshall(event);
console.log(serializedEvent);
Deserialization of Event Streams
This feature allows you to deserialize an event stream received over the network back into its original format. The code sample demonstrates how to create an instance of EventStreamMarshaller and deserialize an event.
const { EventStreamMarshaller } = require('@aws-sdk/eventstream-serde-universal');
const marshaller = new EventStreamMarshaller();
const serializedEvent = /* some serialized event data */;
const event = marshaller.unmarshall(serializedEvent);
console.log(event);
Other packages similar to @aws-sdk/eventstream-serde-universal
event-stream
The 'event-stream' package is a toolkit for working with streams in Node.js. It provides a variety of utilities for creating and manipulating streams, including serialization and deserialization. While it is more general-purpose compared to @aws-sdk/eventstream-serde-universal, it can be used for similar tasks involving event streams.
kinesis-client-library
The 'kinesis-client-library' package is specifically designed for working with AWS Kinesis streams. It provides higher-level abstractions for consuming and processing Kinesis streams, including serialization and deserialization of event data. It is more specialized compared to @aws-sdk/eventstream-serde-universal, which is more general-purpose for AWS event streams.
