@aws-sdk/middleware-serde

What is @aws-sdk/middleware-serde?

@aws-sdk/middleware-serde is a middleware package for the AWS SDK for JavaScript. It provides serialization and deserialization capabilities for AWS service requests and responses. This middleware is essential for converting data to and from the wire format used by AWS services.

What are @aws-sdk/middleware-serde's main functionalities?

Serialization Middleware

This feature allows you to add serialization logic to the client stack, converting input data into the format required by AWS services.

const { SerdePlugin } = require('@aws-sdk/middleware-serde');
const { HttpRequest } = require('@aws-sdk/protocol-http');

const serializeMiddleware = (next, context) => async (args) => {
  const request = new HttpRequest(args.input);
  // Add serialization logic here
  return next({ ...args, request });
};

const clientStack = [];
clientStack.push(serializeMiddleware);

console.log('Serialization middleware added to client stack.');

Deserialization Middleware

This feature allows you to add deserialization logic to the client stack, converting response data from AWS services into a usable format.

const { SerdePlugin } = require('@aws-sdk/middleware-serde');
const { HttpResponse } = require('@aws-sdk/protocol-http');

const deserializeMiddleware = (next, context) => async (args) => {
  const response = new HttpResponse(args.output);
  // Add deserialization logic here
  return next({ ...args, response });
};

const clientStack = [];
clientStack.push(deserializeMiddleware);

console.log('Deserialization middleware added to client stack.');

Other packages similar to @aws-sdk/middleware-serde

axios

Axios is a promise-based HTTP client for the browser and Node.js. It provides functionalities for making HTTP requests and handling responses, similar to the serialization and deserialization capabilities of @aws-sdk/middleware-serde. However, Axios is more general-purpose and not specifically tailored for AWS services.

superagent

Superagent is a small progressive client-side HTTP request library. It provides a flexible API for making HTTP requests and handling responses, similar to the serialization and deserialization features of @aws-sdk/middleware-serde. Like Axios, Superagent is not specifically designed for AWS services.
