| If you're using Vue 3, you're probably using composables. But other than using VueUse where you can, how do you get the most out of them? Over the past few years I've been slowly putting together a list of patterns and best practices for how to write composables in the best way.
I've spent hours reading the source code of VueUse (one of the best — but most time-consuming — ways to learn it).
I've read articles, listened to talks, and written lots and lots of my own code. I ended up with 15 different patterns, and each one will help you to write better composables. I've condensed and put all of these composables together into a course — Composable Design Patterns. Get Composable Design Patterns now. Because this is the launch, it's on sale for 35% off until Thursday. For each of the 15 patterns in this course, you'll get: - A concise overview that tells you when and how to use it, along with variations and edge cases you need to know
- Real-world demos showcasing the pattern in action
- Step-by-step refactoring guides showing how to apply the pattern to your own code
Here's a taste of what you'll learn: - Master the "Thin Composables Pattern" to separate reactivity from business logic — a technique senior Vue developers use to simplify debugging and testing.
- Transform messy parameter lists into clean, maintainable code with the Options Object Pattern — the professional approach to function inputs.
- Discover the Reactivity Boundary Pattern: Strategic placement of reactivity breaks to prevent cascading updates and improve performance.
- Beyond Pinia: Learn lightweight state management techniques that eliminate prop drilling without the overhead of a full state manager.
- Harness the power of TypeScript in Vue with
MaybeRef<T> and other utility types for type-safe composables. - Scale with confidence using the Dynamic Return Pattern — future-proof your features from day one.
- Write testable composables by cleanly separating business logic from reactivity concerns.
- Create framework-agnostic logic that seamlessly ports between Vue, React, and other frameworks — making it more robust and reusable.
- Master dependency isolation techniques to build truly independent, maintainable components.
- Leverage
toValue() to elegantly handle refs, raw values, and computed properties in your composables. Remember, the 35% off sale ends this Thursday! Here's the link again if you'd like to check it out: Composable Design Patterns in Vue Have a great day! — Michael |
