@smithy/eventstream-serde-browser

What is @smithy/eventstream-serde-browser?

@smithy/eventstream-serde-browser is a package designed to handle serialization and deserialization of event streams in a browser environment. It is part of the AWS SDK for JavaScript and is used to process event streams, which are sequences of events that can be sent and received over a network connection.

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

Serialization of Event Streams

This feature allows you to serialize an event stream into a format that can be transmitted over a network. The code sample demonstrates how to create an instance of EventStreamMarshaller and serialize an event.

const { EventStreamMarshaller } = require('@smithy/eventstream-serde-browser');

const marshaller = new EventStreamMarshaller();
const event = { eventType: 'example', data: 'sample data' };
const serializedEvent = marshaller.serialize(event);
console.log(serializedEvent);

Deserialization of Event Streams

This feature allows you to deserialize a received event stream back into its original event format. The code sample shows how to create an instance of EventStreamMarshaller and deserialize a binary event stream.

const { EventStreamMarshaller } = require('@smithy/eventstream-serde-browser');

const marshaller = new EventStreamMarshaller();
const serializedEvent = new Uint8Array([/* some binary data */]);
const event = marshaller.deserialize(serializedEvent);
console.log(event);

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

eventsource

The 'eventsource' package is a polyfill for the EventSource interface, which allows web applications to receive server-sent events. Unlike @smithy/eventstream-serde-browser, which focuses on serialization and deserialization of event streams, 'eventsource' is more about establishing a connection to receive events from a server.

websocket-stream

The 'websocket-stream' package provides a stream interface for WebSockets. It allows you to send and receive data over WebSocket connections using Node.js streams. While @smithy/eventstream-serde-browser is focused on event stream serialization and deserialization, 'websocket-stream' is more about managing WebSocket connections and data transfer.

rxjs

The 'rxjs' package is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. It can be used to handle event streams in a reactive manner. Unlike @smithy/eventstream-serde-browser, which is specifically for serialization and deserialization, 'rxjs' provides a broader set of tools for working with asynchronous data streams.
