Join the Top 1% of Vue Developers
Master the advanced reactivity concepts that separate the best developers from the rest: effect scopes, custom refs, and the deep internals that power Vue.
Most Vue developers never learn these advanced concepts. Those who do become the top 1% that teams rely on for the most challenging problems. This course will get you there:
- Master Effect Scopes Like a Vue Core Team Member — understand the internal building blocks that 99% of developers never touch
- Control Watcher Timing with Surgical Precision — learn the advanced patterns that separate senior developers from the rest
- Build Custom Refs That Solve Impossible Problems — create specialized reactive references that make you indispensable to your team
- Debug Reactivity Like a Vue Expert — use the secret hooks that let you see exactly what Vue is doing under the hood
- and become the Vue developer everyone comes to for the hard problems!
Advanced Reactivity
What you'll learn
- Understand Effect Scopes: Discover the fundamental building blocks of Vue's reactivity system that you're already using to automatically manage and clean up reactive effects.
- Use Reactivity Outside of Vue: Unlock the power of Vue's reactivity system in plain JavaScript, opening up new possibilities for reactive programming in any environment.
- Create Long-Running Effect Scopes: Build shared state systems that persist across multiple components while avoiding memory leaks and broken reactivity.
- Master Advanced Watchers: Control watcher timing with post-flush and sync options, plus learn to pause, resume, and stop watchers dynamically.
- Debug Reactivity Issues: Use Vue's built-in debugging tools with `onTrack` and `onTrigger` hooks to diagnose tracking issues and troubleshoot reactive effects.
- Build Custom Refs: Create specialized reactive references with complete control over tracking and triggering behavior for custom reactivity patterns.
- Optimize Performance: Learn to temporarily or permanently opt out of reactivity using `toRaw` and `markRaw` to prevent unnecessary reactive overhead.
- Create Writable Computed Refs: Build custom two-way data binding solutions and even recreate Vue's `defineModel` from scratch.

Still have questions?
What prerequisites do I need for the Advanced Reactivity course?
You should have a solid understanding of Vue 3's basic reactivity system including refs, computed properties, and watchers. Basic JavaScript knowledge is also required. This is designed for advanced Vue developers who want to master the complex parts of the reactivity system.
Is this course suitable for beginners?
No. This course covers advanced topics like effect scopes, custom refs, and advanced watcher patterns. If you're new to Vue, start with the basics of reactivity first.
How long does it take to complete the Advanced Reactivity course?
The course is estimated to take about 10 hours to complete, but it's designed as both a learning path and a reference guide. You can work through it at your own pace.
Do I get both video and written content?
Yes! You get 1.5 hours of video content plus the complete written version of the course. The written version includes everything from the videos, so you can learn in whatever format works best for you.
Are the videos subtitled?
Yes! The videos include professional subtitles in 10 languages: German, French, Hindi, Italian, Japanese, Dutch, Polish, Portuguese, Russian, and Chinese. If you want me to add your own language, please email me at michael@michaelnthiessen.com.
What's the difference between the three tiers (Essentials, Premium, Mastery)?
Essentials (9 lessons) covers Effect Scopes. Premium (11 lessons) adds Advanced Watchers. Mastery (22 lessons) includes everything — Effect Scopes, Advanced Watchers, Custom Refs, and Reactivity Debugging. See the full lesson breakdown on the course page.
How hands-on is this course?
Very hands-on! All 22 lessons include practical exercises. You'll learn by building and implementing real reactivity patterns, not just watching passively (but of course you can just binge watch the videos if you want).
Is this course updated for the latest Vue version?
Yes, this course is updated for Vue 3.5 and will be updated for 3.6 when it becomes stable.
What is the refund policy?
You can get a full refund within 30 days of purchase if you're not satisfied with the course. Just email me at michael@michaelnthiessen.com and I'll refund you!

Are there student discounts available?
No. These courses are designed to help professional developers solve real problems in their work. Students typically won't find much practical value in the advanced content.
Are future updates included in my purchase?
Yes! You get lifetime access to the course and any future updates at no additional cost.
Do I need to be online to access the course?
Yes, the course is delivered through the online platform and requires an internet connection.
Can I share my course access with others?
No, course access is for individual use only. Each person needs their own license.

Do you offer corporate or team licenses?
For team purchases or corporate training, please contact me at michael@michaelnthiessen.com to discuss options and pricing.
Will learning advanced reactivity help with performance issues?
Yes, it can! Understanding effect scopes, custom refs, and reactivity debugging will help you identify and solve performance problems related to reactive overhead and memory leaks.
Can I use these patterns in production applications?
Absolutely. All patterns taught are production-ready and used in real Vue applications. The course emphasizes practical, real-world usage.
Does this cover SSR (Server-Side Rendering) considerations?
The course focuses on the core reactivity system, which works the same in SSR and client-side applications. Specific SSR considerations are not the main focus.
Will this help me debug reactivity issues?
Yes! Lesson 16 specifically covers debugging computed refs and watchers using onTrack and onTrigger hooks. You'll learn to diagnose tracking issues and troubleshoot reactive behavior.
Are these Vue-specific patterns or general reactive programming?
These are very Vue-specific implementations.
How does the AI tutor work?
The course includes an AI tutor for Cursor (which can be extended to other AI tools). You can ask questions in natural language, get guided hints without spoilers, and receive clear explanations. The AI tutor is designed to help you understand the "why" behind the code, not just give you the answers. It works best with models like gpt-5-fast, gpt-4.1, or Claude Sonnet 4.
