Good examples of Go back ends?

[george looshch]

hi!
can i please ask if someone knows good examples of back ends written in Go? If not good, just production code would be great as well!
thanks in advance and have a great rest of the weekend!

This question is too vague.

You are likely to get more helpful answers if you specify what kind of "backend" you are looking for.  As it is, we can only guess.  

Do you want backends that are web servers? (see the standard library net/http or the caddy web server)  Is it a backend for iOS iPhone Apps? For Android Apps? That respond to a specific kind of RPC such as gRPC? That simply access a database?...  A relational database? A non-relational database (graph?, vector?, full-text search?) 

Pocketbase is a backend mentioned recently on hackernews, that is written in Go and seems to do alot.  Perhaps it is similar to firebase, just going by the name. I have not used it myself.  I cannot say whether it is a "good example" or not, because I've not used it, and similarly this is too vague a criteria (good at what?)

https://github.com/pocketbase/pocketbase

Generally, go over to github and search for the kind of backend you want, and select those projects that are written in Go on the left side filter click-boxes.  You could also look at the curated lists of Go libraries such as https://awesome-go.com/

hi Jason,

thanks a million for pointing out the vagueness of my question! English isn’t my mother tongue so now i see where you’re coming from

what i meant was examples of real-world web server with routing, authentication, DB, etc.

curated lists have libraries and frameworks, what i’m looking for is examples of usages these libraries and frameworks in production. Search on github didn’t yield any good results, unfortunately

github.com/robaho/go-trader has many easy to follow examples - authentication, multicast , routing, rest apis, websockets. A major system not covered though is db access.

thanks, Robert!

Much of the code backing the official Go website and infrastructure is open source and hosted (or at least mirrored into) the golang Github project at https://github.com/golang

Some specific examples:

• pkgsite, the backend for pkg.go.dev: https://github.com/golang/pkgsite
• vulndb, the backend for the Go vulnerability database: https://github.com/golang/vulndb
• website, the go.dev and Go tour website: https://github.com/golang/website
• playground, the go.dev/play backend: https://github.com/golang/playground

There's probably not much auth handling in any of those but it should meet the rest of your criteria.

oh that’s lovely, thank you, Jason!

Hi George,

I highly suggest you check out the Fiber web framework. You will find the framework interesting.

This repo has a list of many examples using Fiber – https://github.com/gofiber/recipes

Scroll through the repository, and you will most likely find what you are looking for.

[Steven Hartland]

It's high level, but there's some good stuff mentioned in https://github.com/avelino/awesome-go

hey Abu,

thanks, looks interesting!

hi Steven,

thanks for the link! As was noted previously, i did a terrible job at expressing my question initially; what i really meant was examples of real-world web server with routing, authentication, DB, etc.

[Charles Forsyth]

Possibly again not exactly what you're looking for, but I still like Alex Edwards' "Let's Go" and "Let's Go Further" as examples of building up realistic backend servers with the different functions you mention (routing, auth, db etc), for at least modest scale. The former is forms-oriented and superficially but you can easily intuit how to extend it to JSON apps, partly because it does emphasise general techniques and structures so you can build your own. The second book starts with apis. I found the books clear and useful. I think the db is MySQL in the first book and PostgresSQL in the second. From 1.22, one might consider using net/http.ServeMux as the router. One advantage compared to just looking at code is that, being a book and tutorial, it discusses alternatives at every stage.

Jason Phillips excellent suggestion of the 4 Go infrastructure sites is one I'd completely forgotten about!

[Charles Forsyth]

"forms-oriented and superficially but you can" that was supposed to read "forms-oriented but only superficially, and you can"

I also forgot to mention that runnable code comes with both books, with incremental development.

[george looshch]

hello Charles,

first of all, thank you very much for looping in on quite an old thread, appreciate it!

second, thanks a million for the recommendations! Books are absolutely something of my interest, along with real-world examples. I personally a text person (as opposed to video/audio), and books is one of my favorite ways to learn due to ability to mix code and prose in a free form. I don’t mind a material being forms- or anything-else-oriented because, as you rightfully noted, i can adapt the learnings to my particular case, no problem with that!

on Jason Phillips’ suggestion: sorry but i couldn’t find it, would you mind sharing a link please? Thanks in advance!
