/pure build throws in browsers not supporting async-await #486
Description
More of a problem with kcd-scripts but I'm filing it here since the use case is more obvious. Feel free to transfer the issue.
react-testing-libraryversion: 9.1.4reactversion: N/Anodeversion: N/Anpm(oryarn) version: N/A
Relevant code or config:
import '@testing-library/react/pure'What you did:
Used @testing-library/react in IE11
What happened:
Threw with unexpected identifier (due to async-await)
Reproduction:
failing build: https://circleci.com/gh/mui-org/material-ui/113431
Problem description:
kcd-scripts build will use babel but ignore any browserslists assuming the target is node: 8. Only rollup and webpack bundles will load browserslist
Suggested solution:
Add a browserslist targetting ie 11, node 8 and the last 3 versions of the evergreen browsers as well as:
No special case for babel targets. It should always use .browserslistrc since that supports a node entry as well. I think it didn't use to support a node version since I occasionally encounter a repository using browserslist but throwing with a node entry.
