Julia focuses on scientific computing and data science. But thanks to its great qualities as a generic programming language, its native parallel computing features, and its performance, we have an excellent use case for Julia in the area of web development.
The package ecosystem provides access to a powerful set of libraries dedicated to web programming. They are relatively low level, but still abstract away most of the complexities of working directly with the network stack. The HTTP package provides a good balance between usability, performance, and flexibility.
The fact that we managed to build a fairly complex (albeit small) web app with so little code is a testimony to the power and expressiveness of the language and to the quality of the third-party libraries. We did a great job with our learning project—it's now time to relax a bit and enjoy a round...
