Racket’s a great language, and its HTTP server is a delight to work with.
Racket’s approach can, at times, appear somewhat unusual (and not just for newcomers). I made this site, and my ebook Server: Racket, to help you get into web development with Racket, whether you’re fresh to the scene or coming in with previous experience in other programming languages & web development frameworks.
In addition to Server: Racket, you'll also find Racket Weekend, a brief introduction to Racket, as well as Language-oriented Programming in Racket: A Cultural Anthropology, a survey of language-oriented programming. See the course listing for more details.
