Choosing the right names makes your Go code clearer, more predictable, and easier to navigate — bad names do the opposite. I’ve just published a beginner-friendly guide covering naming conventions, practical tips, and examples: www.alexedwards.net/blog/go-nami...

It’s that time of year again! 🎁Treat yourself to some holiday Golang learning with 30% off my books Let’s Go and Let’s Go Further — offer on until Dec 1st. Both books are fully updated for the latest Go 1.25 release. lets-go.alexedwards.net lets-go-further.alexedwards.net

I’ve written a new tutorial on Go’s CrossOriginProtection middleware, explaining how it works and how you can combine it with SameSite cookies and TLS 1.3 to effectively prevent CSRF attacks. www.alexedwards.net/blog/prevent...

Way back in 2014 I wrote a blog post "Making and using HTTP Middleware in Go", which become one of the most read things I've ever made. I decided it was time to give it a bit of love... I've modernized the examples and restructured the post and explanations to (hopefully!) improve it further.

I've just finished writing a new blog post "How to manage configuration settings in Go web applications". I talks through patterns for using flags, env vars and config files, and how to pass settings to where they are needed in your application code. www.alexedwards.net/blog/how-to-...

It's a bit overdue, but I finally updated my "which #golang router should I use?" blog post to reflect the `http.ServeMux` changes in Go 1.22. www.alexedwards.net/blog/which-g...

New blog post now out: alexedwards.net/blog/organiz... It talks about how to extend Go's http .ServeMux to support middleware 'groups' (like chi), and also a quick and simple alternative to alice for chaining middleware.

Panic! …or maybe not? 🤔 I've just published a new tutorial exploring and answering the question: When is it OK to panic in Go? Give it a read at: alexedwards.net/blog/when-is... I enjoyed writing this one, and it was good to clarify and codify how I've been using panics for a long time.
