JSON-to-Go: Convert JSON to Go instantly
This tool instantly converts JSON into a Go type definition. Paste a JSON structure on the left and the equivalent Go type will be generated to the right, which you can paste into your program. The script has to make some assumptions, so double-check the output! For an example, try converting JSON from the SmartyStreets API or the GitHub API. © 2015 Matt Holt (@mholt6) • View on GitHub • Dark mode

JSON and Go - The Go Programming Language
Andrew Gerrand 25 January 2011 Introduction JSON (JavaScript Object Notation) is a simple data interchange format. Syntactically it resembles the objects and lists of JavaScript. It is most commonly used for communication between web back-ends and JavaScript programs running in the browser, but it is used in many other places, too. Its home page, json.org, provides a wonderfully clear and concise
Strings, bytes, runes and characters in Go - The Go Programming Language
Rob Pike 23 October 2013 Introduction The previous blog post explained how slices work in Go, using a number of examples to illustrate the mechanism behind their implementation. Building on that background, this post discusses strings in Go. At first, strings might seem too simple a topic for a blog post, but to use them well requires understanding not only how they work, but also the difference b

Benchmarking Nginx with Go
benchmark+go+nginx.md Benchmarking Nginx with Go There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts
