Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
@types/retry
Advanced tools
The @types/retry package provides TypeScript type definitions for the 'retry' npm package, which is a utility for retrying operations that might fail. It allows developers to implement retry logic with various strategies and options, making it easier to handle transient failures in applications. The types package doesn't add functionality but offers type support for TypeScript users of 'retry'.
Creating a retry operation
This feature allows you to create a retry operation. You can specify the operation you want to retry, such as a network request. The `attempt` method is used to try the operation, and `retry` is called if the operation fails, until the maximum number of attempts is reached.
import * as retry from 'retry';
const operation = retry.operation();
operation.attempt((currentAttempt) => {
// Your operation here, e.g., a network request
if (networkError) {
if (operation.retry(networkError)) {
return;
}
// Handle the network error after max retries
}
});
Customizing retry options
This feature demonstrates how to customize the retry operation with specific options. You can set the maximum number of retries, the exponential backoff factor, minimum and maximum timeout between retries, and whether to randomize the retry intervals.
import * as retry from 'retry';
const operation = retry.operation({
retries: 5, // Maximum number of attempts
factor: 2, // The exponential factor
minTimeout: 1 * 1000, // The number of milliseconds before starting the first retry
maxTimeout: 60 * 1000, // The maximum number of milliseconds between two retries
randomize: true, // Randomizes the timeouts by multiplying with a factor between 1 to 2
});
Similar to 'retry', 'async-retry' provides retry functionality specifically designed for asynchronous operations. It supports both promise-based and async/await syntax, making it a good alternative for modern JavaScript and TypeScript applications. Unlike @types/retry, which is just type definitions, 'async-retry' is a standalone package that doesn't require separate type definitions.
This package is a promise-based retry library that offers a simple API for retrying operations. It is very similar to 'async-retry' but focuses more on promises. 'p-retry' is useful for applications heavily utilizing promises. It differs from @types/retry in that it's specifically designed for promise-based operations and also doesn't require separate type definitions for TypeScript users.
