At some point, when modules get "micro" enough, the effort of managing them and learning their usage outweighs the effort of implementing the thing yourself. Most JavaScript projects seem to walk that line quite closely.

I'm a React developer at work, but I recently gave Vue a try at home. This is one of the things that most stood out to me about it. React makes a selling point out of the fact that it's "just rendering". It doesn't try to do everything for you, it tries to do one thing really well. That sounds great, but it leaves out a factor. Having your primary framework be "simple" and "lean" doesn't translate to your project being simple and lean, because your project still needs all that other stuff. You just now have to get it from somewhere else, which often adds more complexity than it's worth.

When I downloaded Vue all I had to do was add a script tag to my HTML document and start writing a modern reactive UI. No other modules or frameworks. No build system. No special JS-targeted languages. Vue does everything you need, and it does it all pretty well, and sometimes that's more valuable.
