toxy - Hackable HTTP proxy for resiliency testing and simulated network conditions

Hackable HTTP proxy to simulate server failure scenarios, resiliency and unexpected network conditions, built for node.js.It was mainly designed for failure resistance testing, when toxy becomes particularly useful in order to cover fault tolerance and resiliency capabilities of a system, especially in disruption-tolerant networks and service-oriented architectures, where toxy may act as MitM proxy among services in order to inject failure.

node-s3-client - high level amazon s3 client for node.js

See also the companion CLI tool which is meant to be a drop-in replacement for s3cmd: s3-cli.This contains a reference to the aws-sdk module. It is a valid use case to use both this module and the lower level aws-sdk module in tandem.

resilience4j - Resilience4j is a fault tolerance library designed for Java8 and functional programming

Resilience4j is a lightweight fault tolerance library inspired by Netflix Hystrix, but designed for Java 8 and functional programming. Lightweight, because the library only uses Vavr (formerly Javaslang), which does not have any other external library dependencies. Netflix Hystrix, in contrast, has a compile dependency to Archaius which has many more external library dependencies such as Guava and Apache Commons Configuration. With Resilience4j you don’t have to go all-in, you can pick what you need. Setup and usage is described in our User Guide.

tenacity - Retrying library for Python

Tenacity is an Apache 2.0 licensed general-purpose retrying library, written in Python, to simplify the task of adding retry behavior to just about anything. It originates from a fork of retrying. The simplest use case is retrying a flaky function whenever an Exception occurs until a value is returned.

node-graceful-fs - fs with incremental backoff on EMFILE

graceful-fs functions as a drop-in replacement for the fs module, making various improvements.The improvements are meant to normalize behavior across different platforms and environments, and to make filesystem access more resilient to errors.

guava-retrying - This is a small extension to Google's Guava library to allow for the creation of configurable retrying strategies for an arbitrary function call, such as something that talks to a remote service with flaky uptime

##What is this? The guava-retrying module provides a general purpose method for retrying arbitrary Java code with specific stop, retry, and exception handling capabilities that are enhanced by Guava's predicate matching. This is a fork of the excellent RetryerBuilder code posted here by Jean-Baptiste Nizet (JB). I've added a Gradle build for pushing it up to my little corner of Maven Central so that others can easily pull it into their existing projects with minimal effort. It also includes exponential and Fibonacci backoff WaitStrategies that might be useful for situations where more well-behaved service polling is preferred.

gentleman - Full-featured, plugin-oriented, composable HTTP client toolkit for Go

Full-featured, plugin-driven, middleware-oriented toolkit to easily create rich, versatile and composable HTTP clients in Go.gentleman embraces extensibility and composition principles in order to provide a flexible way to easily create featured HTTP client layers based on built-in or third-party plugins that you can register and reuse across HTTP clients.

Error Handling Block

Provides customizable handling of transient errors. Built-in handlers for WCF, WebClient, HttpRequest. For .NET, Silverlight, Store App, Windows Phone.

retry - A simple, stateless, functional mechanism to perform actions repetitively until successful.

A simple, stateless, functional mechanism to perform actions repetitively until successful. This project is currently in "pre-release". While the code is heavily tested, the API may change. Vendor (commit or lock) this dependency if you plan on using it.

backoff - Python library providing function decorators for configurable backoff and retry

This module provides function decorators which can be used to wrap a function such that it will be retried until some condition is met. It is meant to be of use when accessing unreliable resources with the potential for intermittent failures i.e. network resources and external APIs. Somewhat more generally, it may also be of use for dynamically polling resources for externally generated content.Decorators support both regular functions for synchronous code and asyncio's coroutines for asynchronous code.

riprova - Versatile Python library for retrying failed operations with configurable backoff strategies

riprova (meaning retry in Italian) is a small, general-purpose and versatile Python library that provides retry mechanisms with multiple backoff strategies for any sort of failed operations.It's domain agnostic, highly customizable, extensible and provides a minimal API that's easy to instrument in any code base via decorators, context managers or raw API consumption.

recovery - Recover from a network failure using randomized exponential backoff.

Recovery provides randomized exponential back off for reconnection attempts. It allows you to recover the connection in the most optimal way (for both server and client). The exponential back off is randomized to prevent a DDoS like attack on your server when it's restarted, spreading the reconnection attempts instead of having all your connections attempt to reconnect at exactly the same time.The code base of this module was originally written for Primus but has been extracted as separate module. It has been thoroughly tested and it's written with love <3.

node-promise-retry - Retries a function that returns a promise, leveraging the power of the retry module

Retries a function that returns a promise, leveraging the power of the retry module to the promises world.There's already some modules that are able to retry functions that return promises but they were rather difficult to use or do not offer an easy way to do conditional retries.

node-request-replay - Replays a request when a network error occurs using the retry module

Replays a request when a network error occurs using the retry module.DO NOT use this module if you are piping request instances. If you are listening to data events to buffer, beware that you must reset everything when a replay occurs. This is why pipping is not supported.

s3-write-stream - Pipe data straight to an S3 key of your choice

Pipe data straight to an S3 key of your choice.This is a writeable stream that takes data and uploads it to Amazon S3 using its multipart upload API. This is ideal for handling generated content without needing to know the content's length ahead of time, and without resorting to file system hacks or buffering everything before the upload.

retry-request - Retry a request with built-in exponential backoff.

It should work the same as request in both callback mode and stream mode.Note: This module only works when used as a readable stream, i.e. POST requests aren't supported (#3).
