> the [Svelte] user base is very small compared to the react world. In the end, we judged svelte too risky to depend on.

So your custom framework user base is much bigger than Svelte's or is it just you and a couple people on your team?

Here are some actual criticisms I have of Svelte:

Rich Harris thinks it's fast because it doesn't use a virtual DOM. No, it's fast because V8 speed has increased dramatically since React found a virtual DOM necessary. Now React is stuck with it's virtual DOM. But sure Richard, take the credit for being fast if you want.

A command line tool to parse some text based .svelte files and assemble them into regular browser files is almost trivial, not rocket science. Adding hashes to the CSS identifiers to namespace is also not hard.

Data binding and reactive programming are part of the observer pattern in the Gang of Four book. Rich Harris invented some sugar reactive syntax, but more power to him. I just don't think Svelte does that much.

Edit: Rich not Richard
