Syntax Error with Optional Chaining in Typescript 3.9.7

🐛 Bug Report

Jest encountered an unexpected token

This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

Here's what you can do:
 • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
 • If you need a custom transformation specify a "transform" option in your config.
 • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html

Details:

Expected behavior

Link to runnable example or repository (highly encouraged)

UI Kitten and Eva version

Package	Version
@eva-design/eva	5.0.0
@ui-kitten/components	5.0.0

And I also know that all UI-Kitten components should be rendered in a provider. I have a custom render fn just like this

  return (
    <ApplicationProvider mapping={mapping} theme={currentTheme} customMapping={currentMapping}>
      {children}
    </ApplicationProvider>
  )

this, by the way, does not work ether, because of the same transpilation error

The babel transpilation magic seems to work just fine according to first example. I have no idea of why this can be broken if I use any @ui-kitten component

You are welcome!

kuznetsov-from-wonderland commented 4 years ago

I guess this issue will probably disappear if I upgrade to Node v14 ☝️

lesmo commented 3 years ago

This is sad. I've had to forcibly transpile it with Babel, and I'm not sure if it's the reason I'm unable to have UI KItten properly tree-shaken 🤔

kuznetsov-from-wonderland commented 3 years ago

Node v14 solves this problem

lesmo commented 3 years ago

Please add to documentation that Node v14 is now a requirement.

icgarlin commented 3 years ago

Upgrading to Node v14 does not work for me
