What is @smithy/middleware-serde?
@smithy/middleware-serde is a middleware package for the Smithy framework that provides serialization and deserialization capabilities. It is used to convert data between different formats, such as JSON and XML, and to handle the transformation of request and response data in a consistent manner.
What are @smithy/middleware-serde's main functionalities?
Serialization Middleware
This feature allows you to add serialization middleware to a Smithy client. The middleware handles the conversion of request data into the appropriate format before sending it to the server.
const { getSerdePlugin } = require('@smithy/middleware-serde');
const { Client } = require('@smithy/client');
const client = new Client({
region: 'us-west-2',
plugins: [getSerdePlugin()]
});
// Example request
const request = {
operation: 'SomeOperation',
input: { key: 'value' }
};
client.send(request).then(response => {
console.log(response);
}).catch(error => {
console.error(error);
});
Deserialization Middleware
This feature allows you to add deserialization middleware to a Smithy client. The middleware handles the conversion of response data from the server into the appropriate format for the client.
const { getSerdePlugin } = require('@smithy/middleware-serde');
const { Client } = require('@smithy/client');
const client = new Client({
region: 'us-west-2',
plugins: [getSerdePlugin()]
});
// Example request
const request = {
operation: 'SomeOperation',
input: { key: 'value' }
};
client.send(request).then(response => {
console.log(response);
}).catch(error => {
console.error(error);
});
Other packages similar to @smithy/middleware-serde
axios
Axios is a popular HTTP client for Node.js and the browser. It provides similar functionalities for handling request and response transformations, including serialization and deserialization of data. However, Axios is more general-purpose and not specifically tied to the Smithy framework.
superagent
Superagent is another HTTP client library for Node.js and the browser. It offers features for handling request and response transformations, including serialization and deserialization. Like Axios, Superagent is a general-purpose library and not specifically designed for the Smithy framework.
request
Request is a simplified HTTP client for Node.js. It provides functionalities for handling request and response data transformations, including serialization and deserialization. Although it is not as actively maintained as Axios or Superagent, it is still widely used in many projects.
