The conventional wisdom on this topic is mostly wrong. Here's why.
If you search online for advice about Package Management, you will find thousands of articles with contradicting recommendations. After testing many of these approaches in real production environments, I can tell you which principles actually hold up under pressure.
The Bigger Picture
I want to talk about tree shaking specifically, because it's one of those things that gets either overcomplicated or oversimplified. The reality is somewhere in the middle. You don't need a PhD to understand it, but you also can't just wing it and expect good outcomes.
Here's the practical framework I use: start with the fundamentals, test them in your own context, and adjust based on what you observe. This isn't glamorous advice, but it's the advice that actually works. Anyone telling you there's a shortcut is probably selling something.
What makes this particularly relevant right now is worth explaining.
What to Do When You Hit a Plateau

Let's get practical for a minute. Here's exactly what I'd do if I were starting from scratch with Package Management:
Week 1-2: Focus purely on understanding the fundamentals. Don't try to do anything fancy. Just get the basics down.
Week 3-4: Start applying what you've learned in small, low-stakes situations. Pay attention to what works and what doesn't.
Month 2-3: Begin pushing your boundaries. Try more challenging applications. Expect to fail sometimes — that's part of the process.
Month 3+: Review your progress, identify weak spots, and drill down on them. This is where consistent practice turns into genuine competence.
The Long-Term Perspective
Environment design is an underrated factor in Package Management. Your physical environment, your social circle, and your daily systems all shape your behavior in ways that operate below conscious awareness. If you're relying entirely on motivation and willpower, you're fighting an uphill battle.
Small environmental changes can produce outsized results. Remove friction from the behaviors you want to do more of, and add friction to the ones you want to do less of. When it comes to event-driven architecture, making the right choice the easy choice is more powerful than trying to make yourself choose correctly through sheer determination.
Putting It All Into Practice
Let me share a framework that transformed how I think about build optimization. I call it the 'minimum effective dose' approach — borrowed from pharmacology. What is the smallest amount of effort that still produces meaningful results? For most people with Package Management, the answer is much less than they think.
This isn't about being lazy. It's about being strategic. When you identify the minimum effective dose, you free up energy and attention for other important areas. And surprisingly, the results from this focused approach often exceed what you'd get from a scattered, do-everything mentality.
Now hold that thought, because it ties into what comes next.
Dealing With Diminishing Returns
One thing that surprised me about Package Management was how much the basics matter even at advanced levels. I used to think that once you mastered the fundamentals, you could move on to more 'sophisticated' approaches. But the best practitioners I know come back to basics constantly. They just execute them with more precision and understanding.
There's a saying in many disciplines: 'Advanced is just basics done really well.' I've found this to be absolutely true with Package Management. Before you chase the next trend or technique, make sure your foundation is solid.
The Environment Factor
Timing matters more than people admit when it comes to Package Management. Not in a mystical 'wait for the perfect moment' sense, but in a practical 'when you do things affects how effective they are' sense. error boundaries is a great example of this — the same action taken at different times can produce wildly different results.
I used to do things whenever I felt like it. Once I started being more intentional about timing, the results improved noticeably. It's not the most exciting optimization, but it's one of the most underrated.
The Emotional Side Nobody Discusses
I've made countless mistakes with Package Management over the years, and honestly, most of them were valuable. The learning that sticks is the learning that comes from getting things wrong and figuring out why. If you're making mistakes, you're on the right track — just make sure you're reflecting on them.
The one mistake I'd urge you to AVOID is paralysis by analysis. Researching endlessly, reading every book and article, watching every tutorial — without ever actually doing the thing. At some point you have to put the theory down and start practicing. The real education begins there.
Final Thoughts
The best time to start was yesterday. The second best time is right now. Go make it happen.
