Julia Programming Projects

Overview of this book

Julia is a new programming language that offers a unique combination of performance and productivity. Its powerful features, friendly syntax, and speed are attracting a growing number of adopters from Python, R, and Matlab, effectively raising the bar for modern general and scientific computing. After six years in the making, Julia has reached version 1.0. Now is the perfect time to learn it, due to its large-scale adoption across a wide range of domains, including fintech, biotech, education, and AI. Beginning with an introduction to the language, Julia Programming Projects goes on to illustrate how to analyze the Iris dataset using DataFrames. You will explore functions and the type system, methods, and multiple dispatch while building a web scraper and a web app. Next, you'll delve into machine learning, where you'll build a books recommender system. You will also see how to apply unsupervised machine learning to perform clustering on the San Francisco business database. After metaprogramming, the final chapters will discuss dates and time, time series analysis, visualization, and forecasting. We'll close with package development, documenting, testing and benchmarking. By the end of the book, you will have gained the practical knowledge to build real-world applications in Julia.

Learning about Julia's web stack

Julia's package ecosystem has long provided a variety of libraries for building web apps. Some of the most mature are HttpServerMuxWebSockets, and JuliaWebAPI (to name just a few; this list is not exhaustive). But as the ecosystem settled with Julia version 1, a lot of community effort has been put into a newer package, simply known as HTTP. It provides a web server, an HTTP client (which we already used in the previous chapters to fetch the web pages from Wikipedia), as well as various utilities for making web development simpler. We'll learn about key HTTP modules ,such as Server, Router, Request, Response, and HandlerFunction, and we'll put them to good use.


Beginning with a simple example – Hello World

Let's take a look at a simple example of employing the HTTP server stack. This will help us understand the foundational building blocks before we dive into the more complex issue of exposing our game on the web.
