What is @aws-sdk/eventstream-serde-browser?
@aws-sdk/eventstream-serde-browser is a package within the AWS SDK for JavaScript that provides serialization and deserialization of event streams in a browser environment. This is particularly useful for handling AWS services that use event streams, such as AWS Transcribe or AWS Kinesis.
What are @aws-sdk/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 the network. The code sample demonstrates how to create an EventStreamMarshaller and use it to serialize an event.
const { EventStreamMarshaller } = require('@aws-sdk/eventstream-serde-browser');
const marshaller = new EventStreamMarshaller(utf8Encoder, utf8Decoder);
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 a JavaScript object. The code sample demonstrates how to create an EventStreamMarshaller and use it to deserialize a binary event stream.
const { EventStreamMarshaller } = require('@aws-sdk/eventstream-serde-browser');
const marshaller = new EventStreamMarshaller(utf8Encoder, utf8Decoder);
const serializedEvent = new Uint8Array([/* some binary data */]);
const event = marshaller.unmarshall(serializedEvent);
console.log(event);
Other packages similar to @aws-sdk/eventstream-serde-browser
eventsource
The 'eventsource' package is a polyfill for the EventSource API, which allows you to receive server-sent events in a browser environment. While it does not provide serialization and deserialization of event streams, it is useful for handling real-time data streams from a server.
kinesis-client
The 'kinesis-client' package is a client library for AWS Kinesis, which provides functionalities for consuming and processing data streams. It includes features for handling event streams but is more focused on Kinesis-specific use cases compared to the general-purpose event stream serialization/deserialization provided by @aws-sdk/eventstream-serde-browser.
