Golang libraries I refuse to build backend systems without in 2026: 🔶 chi (or gin) = HTTP routing that stays out of your way 🔶 zap (or slog) = structured logging that won’t slow prod 🔶 validator/v10 = request validation that isn’t “if err != nil” spaghetti 🔶 sqlc = type-safe SQL without ORM magic 🔶 pgx = Postgres driver that actually performs 🔶 redis/go-redis = caching + rate limits + locks 🔶 grpc-go = service-to-service calls done right 🔶 protobuf = contracts that don’t break silently 🔶 go-playground/middleware patterns = timeouts, recover, request IDs 🔶 prometheus/client_golang = metrics you can alert on 🔶 OpenTelemetry (otel) = tracing when “it’s slow sometimes” happens 🔶 testify = tests that don’t make you cry 🔶 mockery = sane mocking for interfaces 🔶 uber-go/fx (optional) = DI when the codebase gets big 🔶 golangci-lint = one command to keep code quality honest Which 3 Go libs are non-negotiable for you?

I really never expect it to reach 1.7k stars in two weeks when I pushed it. Looking forward to contributors.

@func25 again thanks @func25 for sharing, really didn't expect it to reach 1.7k stars in two weeks when I pushed it. Looking forward to contributors.

This repository has many Go challenges to help you write idiomatic Go. It looks very promising: github.com/MedUnes/go-kata

I’m building a set of Go katas for experienced engineers. Not algorithms. Not "learn Go" Just real production patterns: context, errgroup, goroutine leaks, HTTP hygiene, error semantics, allocation control. #golang #php #concurrency #java #JavaScript github.com/MedUnes/go-kata

I will write a series of blog posts to share my learning throughout the journey of transitioning to #Go In this first post, I explain why you'd rather stay away from the builder pattern once inside the Go land #golang #php #java #javascript #symfony dev.to/medunes/we-don…

A thread-safe, generic LRU cache implementation for Go, designed for high-throughput systems (GC pauses in mind). It achieves O(1) time complexity for all operations and zero heap allocations during standard R/W cycles github.com/MedUnes/cash #go #golang #softwareengineering

@jwage please define fail: fpm logs, app logs, the upstream's region / reacheability, OS, how often, a simultanous curl to the sipstream or even netcat, etc.. many things can help..

Anyone else run into this on Google Cloud Run We are migrating from Heroku to Cloud Run and some outbound HTTP API calls (using Symfony HttpClient w/ 5s timeout/max_duration) intermittently fail with a timeout or max duration error. Same code works fine on Heroku/AWS. Networking quirk? IPv6? HTTP/2? NAT?

We just moved from: "Automate the #boring stuff with python" to: "Automate the #boring (Automate the #boring stuff with #LLM) with python" It is the instinct of continuously targeting the #boring segment and automating it.
