The com-lihaoyi Scala Platform 🇸🇬

The com-lihaoyi platform lets you write Scala in an easy and productive way while delivering real business value. It provides all the core building blocks a typical software engineer needs day to day: HTTP clients and servers, JSON/binary data serialization, filesystem operations, CLI argument parsing, build tooling, etc. These can be combined in a variety of ways to perform many useful real-world tasks:

The com-lihaoyi organization maintains an ongoing issue bounty program, paying out 100s to 1000s of USD for the completion of various issues. See the up-to-date listing here:

The com-lihaoyi projects are all open source, but if you want to learn more about writing Scala in the easy and productive way, you check out the following book:

Hands-on Scala Programming also comes with over 150 worked examples that demonstrate how to use Scala with the com-lihaoyi projects in a wide variety of real scenarios:

These examples are free to browse online, and are a great way to kickstart your next application, project or business using the Scala programming language.
