Retries Made Better with Faraday Loop— Ever need a simple way to retry a block of code in Ruby? Maybe with a maximum number of retries or exponential backoff? The popular Faraday HTTP client library has a great built-in solution that it uses for retrying HTTP requests which has been extracted into Faraday Loop for us to use elsewhere.

💡 An improvement to last week's tip?

Last week we included a handy tip for using Caddy and mkcert to locally use 'fake' domains of your choice for development purposes. The tip works well, but reader Gamaliel Toro wrote in to point out that Caddy now has this feature built in and you might find it an easier approach.

He's written up the technique in this gist– I struggled to make it work on my first attempt, but this is a last minute addition to the newsletter and the feature does indeed appear to be offered by Caddy. If all else fails, though, the tip in last week's issue still works 😉
