Error Handling Packages
Ergonomic error-handling and result-type libraries that make failure states explicit instead of relying on exceptions (thiserror, anyhow).
Packages in Error Handling
thiserror

errors
Simple Go error handling primitives that add stack traces and context without losing the original cause.
tenacity
A general-purpose Python retrying library that adds configurable retry behavior to almost anything

A TypeScript library and ecosystem for building robust, type-safe, concurrent applications with a full functional effect system
backoff
Exponential backoff and retry for Go, with a generic Retry function, typed errors, and RetryAfter support for rate-limited APIs.

gobreaker
A lightweight, thread-safe circuit breaker for Go that wraps any function call to stop cascading failures when a dependency starts failing.
retry-go
A lightweight Go library for retrying fallible functions with configurable backoff, jitter, and per-error attempt limits.
express-async-errors
A one-line patch that lets Express route handlers throw or reject instead of manually calling next(err).
