Cover image for 7 Lessons I Learned While Building an Open-Source React Component Library

Vladyusha

A few weeks ago, I started building Motoko UI, an open-source React component library.

The goal sounded simple: build beautiful, reusable components.

The reality was very different.

Here are seven lessons I've learned so far.

1. Building Components Is the Easy Part

The first few components took only a couple of days.

The documentation took longer.

The installation flow took longer.

The registry took longer.

It turns out that a component library is much more than a collection of components.

2. Developer Experience Matters More Than Fancy Animations

A beautiful component is useless if developers struggle to install it.

I quickly realized that reducing setup time was more valuable than adding another animation.

That's why I invested time in a registry and simple installation flow.

3. Documentation Is Part of the Product

I used to think documentation came after development.

Now I think documentation is development.

If users can't quickly understand how to use a component, the component effectively doesn't exist.

4. Small Releases Keep You Moving

Instead of waiting until everything was perfect, I started shipping small releases.

Every release adds a few components, fixes issues, and improves documentation.

That momentum makes the project feel alive.

5. Design Consistency Is Harder Than It Looks

Every new component introduces new decisions:

  • spacing
  • shadows
  • colors
  • border radius
  • animation timing

Without clear design principles, the library quickly becomes inconsistent.

6. Open Source Means Listening

Some of the best ideas didn't come from me.

They came from developers trying the project and asking:

"What if this component supported...?"

Those conversations improve the library more than coding alone.

7. The Project Is Never Finished

There's always another component.

Another improvement.

Another refactor.

I've stopped thinking about "finishing" the library.

Now the goal is simply to make it a little better with every release.

Final Thoughts

Building Motoko UI has already taught me far more than I expected.

Whether the project ends up with 100 stars or 10,000, the experience of designing, documenting, and maintaining an open-source library has been worth it.

If you're thinking about starting your own open-source project, my advice is simple:

Start before you think you're ready.
