Programming Crystal: Create High-Performance, Safe, Concurrent Apps

Crystal is elegant to read and easy to program like Ruby, allowing full object-oriented development. Its compiler is powerful enough to nearly always infer the type of your variables. So you get the benefits of a statically typed language: more robust code, safety, and execution speed while still reaching high productivity in development. Null pointer exceptions as in JavaScript, Java, or C#, are a thing of the past: Crystal annihilates them, just like Rust.

Explore the building blocks and design of the language and how you can use the Crystal tool chain to build and manage powerful applications. Harness the power of the macro system, as well as how to work with fibers and channels, making concurrency as easy as possible. Learn how to use the Kemal web framework and access databases and how to tap the potential of existing Crystal libraries. Find the spot that Crystal fills in today's software world with real-world examples.

With Crystal, you can combine the best of both worlds: the high-level coding of dynamic languages and the safety and blazing performance of a natively compiled language.

Now in beta from pragprog.com/book/crystal.
