babel produce multiple duplicates in output bandle file #199

Closed WuglyakBolgoink closed 3 years ago

WuglyakBolgoink commented 4 years ago

Hallo guys!

I found some "feature bug" problem in our output bandle file.

Babel create x-same functions for each file which contain es6 class.

For example currently what we have:

  1. _classCallCheck - 133x
  2. ownKeys - 24
  3. _defineProperties - 198x

Can anyone help me with that or say how I can reduce count of this functions?

PS: we use old angularJS files together with new es6 classes...

By default, Babel injects inline helpers in every file. You can use @babel/plugin-transform-runtime (and add @babel/runtime to your dependencies) to decuplicate them.
