@smithy/eventstream-serde-universal

What is @smithy/eventstream-serde-universal?

@smithy/eventstream-serde-universal is a package designed to handle serialization and deserialization of event streams in a universal manner. It is part of the Smithy framework, which is used for building SDKs for AWS services. This package is particularly useful for working with event-driven architectures and streaming data.

What are @smithy/eventstream-serde-universal's main functionalities?

Serialization

This feature allows you to serialize an event into a format suitable for transmission over a network. The code sample demonstrates how to create an instance of EventStreamMarshaller and use it to serialize an event object.

const { EventStreamMarshaller } = require('@smithy/eventstream-serde-universal');
const marshaller = new EventStreamMarshaller();
const event = { type: 'event', data: 'example data' };
const serializedEvent = marshaller.serialize(event);
console.log(serializedEvent);

Deserialization

This feature allows you to deserialize a received event stream back into a usable event object. The code sample shows how to create an instance of EventStreamMarshaller and use it to deserialize a binary event stream.

const { EventStreamMarshaller } = require('@smithy/eventstream-serde-universal');
const marshaller = new EventStreamMarshaller();
const serializedEvent = new Uint8Array([/* some binary data */]);
const event = marshaller.deserialize(serializedEvent);
console.log(event);

Event Stream Handling

This feature demonstrates handling a stream of events by serializing and then deserializing them. The code sample shows how to process an array of event objects, serialize them, and then deserialize them back to their original form.

const { EventStreamMarshaller } = require('@smithy/eventstream-serde-universal');
const marshaller = new EventStreamMarshaller();
const eventStream = [
  { type: 'event', data: 'data1' },
  { type: 'event', data: 'data2' }
];
const serializedStream = eventStream.map(event => marshaller.serialize(event));
const deserializedStream = serializedStream.map(event => marshaller.deserialize(event));
console.log(deserializedStream);

Other packages similar to @smithy/eventstream-serde-universal

event-stream

The 'event-stream' package is a toolkit for working with streams in Node.js. It provides utilities for creating and manipulating streams, including event streams. Compared to @smithy/eventstream-serde-universal, 'event-stream' is more general-purpose and not specifically designed for AWS SDKs or event serialization/deserialization.

kafka-node

The 'kafka-node' package is a client for Apache Kafka, a distributed event streaming platform. It allows for producing and consuming messages in Kafka. While it provides robust event streaming capabilities, it is specific to Kafka and does not offer the universal serialization/deserialization features of @smithy/eventstream-serde-universal.

rxjs

The 'rxjs' package is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. It is highly versatile and can be used for event streams, but it does not provide built-in serialization/deserialization for event streams like @smithy/eventstream-serde-universal.
