I’m working on an intermediate level Elm book called Practical Elm for a Busy Developer. I wanted to post a quick note about it for people who are not on my mailing list, since I’ve just added a huge new section and the book is 70-80% complete now.

I chose not to include the basics (Elm syntax, the Elm architecture etc.) in the book because I think they are adequately covered by other sources. Instead, it will guide you through the practical tasks of creating applications with Elm: building UIs, styling, working with JSON, interacting with JavaScript code, testing and so on.

What does the book cover?

The focus of the book is on practical topics:

• A discussion of options for creating UIs and styling
• Approaches and tools for preventing and finding bugs
• JSON parsing (the most commonly reported problem Elm newcomers face)
• Making server requests and working with commands
• JS interop and ports
• A discussion of code organisation as your application grows
• A discussion of integrating Elm into a JS application
• An in-depth look at language features such as pattern matching
• Tools for being more productive when writing Elm code

Practical Elm is currently available as an “early access” book, with some of the content yet to be included.
