A free video course to help you integrate (sneak!) Elm into existing web apps
Watch Course Intro
"Once I've learned Elm, how do I introduce it into my apps?"
Once folks discover how delightful it is to program in Elm, they're eager to find ways to use it in existing applications. Not everyone has the luxury of working on a greenfield Elm project. And a big rewrite is impractical and loaded with risk.
So here's a pragmatic idea: you incrementally and strategically convert a small part of your app to Elm. Learn how in this free course!
4 Practical Examples
In this 40-minute video course we walk through several practical ways to slip Elm into an existing, larger application. This is an intermediate course that assumes you're already familiar with the basics of Elm, or have completed our Building Web Apps with Elm course.
Embed Elm Anywhere (4:49) Elm can be set up to render within any element of a page, so you can sprinkle in Elm to taste. It's a practical way to convert small sections of your app. Sneaky!
Subscribe to External Events (13:43) Using an Elm subscription, your embedded code can listen for external events and react accordingly. Just because it's embedded doesn't mean it's cut off from the world.
Listen to WebSocket Messages (6:22) Got a backend websocket server? We'll hook up embedded Elm code to react to websocket messages. Real-time sports scores, anyone?
It's our hope that once you see practical ways that Elm can be integrated into larger apps you'll be inspired to give Elm a spin on your project. For more inspiration, check out this true story of how one developer successfully integrated Elm into his company.
For Elm Developers
This isn't a beginner course intended for developers new to Elm. It's an intermediate course that assumes you're already familiar with the basics of Elm, or you've completed our Building Web Apps with Elm course where we build an Elm web app from scratch.
Meet Mike & Nicole
Hey, there! Mike here. I love to create stuff and teach what I've learned. Over the past 20 years I've taught and used many languages to develop real applications, but there's a quality to Elm that feels special. I discovered it in late 2014 when looking for something fresh and fun to learn over the holidays. I'm as excited about Elm now as I was back then. Elm is what finally got me into functional programming. It made me a better programmer. And so I naturally can't help but want to share it with you!
Together Nicole and I own and run The Pragmatic Studio. We'd love to have you join us in the Studio for this great course! Learn more about us…
