I’ve just published a beginner-friendly guide covering naming conventions, practical tips, and examples:

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.

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.

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.

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.
