    Project mention: อย่าเพิ่งใช้ fiber ถ้ายังไม่ได้อ่าน doc | dev.to | 2023-10-31
  • ws

    Tiny WebSocket library for Go. (by gobwas)

    Project mention: Websocket memory usage | /r/golang | 2023-05-24

    Then take a look at this article - https://www.freecodecamp.org/news/million-websockets-and-go-cc58418460bb/ - using external from Go std lib epoll implementation and https://github.com/gobwas/ws lib it's possible to reduce memory usage per connection drastically. Though keep in mind that this approach is not obvious to implement right and you better to go with STD lib.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • bombardier

    Fast cross-platform HTTP benchmarking tool written in Go

    Project mention: Discussion: Are we entering the golden age of hacking, where software written by language models that "looks correct" to the lazy human operator is used despite being full of vulnerabilities? | /r/hacking | 2023-03-22

    Why? There is a ready script for that https://github.com/codesenberg/bombardier

  • quicktemplate

    Fast, powerful, yet easy to use template engine for Go. Optimized for speed, zero memory allocations in hot paths. Up to 20x faster than html/template

    Project mention: Templ: A language for writing HTML user interfaces in Go | news.ycombinator.com | 2023-12-10

    Here are a couple:



    I'm sure there are many more.

    The thing about these is that performance is often not as good as when using templates, especially when the templates are compiled to native code. Quicktemplate [1] is still the leader here IMO, and I don't think the OP project brings much that couldn't be done pretty easily with QT.

  • fastjson

    Fast JSON parser and validator for Go. No custom structs, no code generation, no reflection (by valyala)

    Project mention: What's the best way to unmarshall this nested JSON? | /r/golang | 2023-06-29

    I’ve used fastjson when unmarshalling to Structs is inconvenient. https://github.com/valyala/fastjson

  • fastcache

    Fast thread-safe inmemory cache for big number of entries in Go. Minimizes GC overhead

    Project mention: Ask HN: Who wants to be hired? (June 2023) | news.ycombinator.com | 2023-06-01


    Here is an example of a bug-fix I made to an existing open source project https://github.com/VictoriaMetrics/fastcache/pull/17

  • hashmap

    A Golang lock-free thread-safe HashMap optimized for fastest read access.

    Project mention: SwissMap: A smaller, faster Golang Hash Table | news.ycombinator.com | 2023-03-31

    I generally just use this one: https://github.com/cornelk/hashmap

    Mostly in that it also gives me lock free performance, which cleans up a lot of defers.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • maroto

    Project mention: fasttemplate VS Salix - a user suggested alternative | libhunt.com/r/fasttemplate | 2023-10-31
  • ojg

    Optimized JSON for Go

    Project mention: Interactive Examples for Learning Jq | news.ycombinator.com | 2023-11-07

    I found Jq to be difficult to use which is why Oj, https://github.com/ohler55/ojg is based on JSONPath. There still are a lot of options but it only takes a couple of help screens to figure out what the options are.

  • metrics

    Lightweight alternative to github.com/prometheus/client_golang (by VictoriaMetrics)

    Project mention: How do I confirm whether I have a memleak from metrics (heap allocs)? | /r/golang | 2023-03-12

    Not the package but the otel collector (https://opentelemetry.io/docs/collector) to push the metrics to Uptrace. I'm using https://github.com/VictoriaMetrics/metrics client to expose the metrics on a certain route.
