Error: only one instance of babel-polyfill is allowed #47

Closed AndreSteenveld closed 6 years ago

AndreSteenveld commented 7 years ago

I have a project where I use mongo-oplog as a dependency, during the startup of the application babel-polyfill is imported. When importing monog-oplog the error "only one instance of babel-polyfill is allowed" is thrown from babel-polyfill.

I've encountered a similar issue before and the found that replacing import 'babel-polyfill' with global._babelPolyfill || require( "babel-polyfill" ); sort of works around the problem but doesn't really solve it because the assumption is made that every library will make sure to check their babel-polyfill import.

I made a fork (aestetype/mongo-oplog) who includes @AndreSteenveld's patch. It's published on npm through @aestetype/mongo-oplog.
