Crystal

Crystal is a compiled programming language with a Ruby-like syntax that produces fast native binaries. Developers use it for web services, command line tools and background workers that need speed without a heavy runtime. This tag collects guides on building feeds and automation with Crystal. Articles explain routes, typed database queries, XML generation with the standard library, date formats and conditional requests with ETag headers. They also show how to connect a Crystal feed to social media so that new items are shared automatically.
