Example to demonstrate errors with @now/node@canary build with nested dependencies.
Examples include a Now hosted Next app with a simple API backend that has one external package dependency, momentjs. If the backend API endpoint JS imports this dependency from an external file, a runtime error is thrown when using now dev or when hosted on now.
No error is thrown when building with @now/node@0.11.1
Run now dev in the notnested_working example, and confirm that the test passes:
cd notnested_working
now dev &
...
[ wait ] compiling ...
> Ready! Available at http://localhost:3000
Test the API call using curl:
yarn test
$ curl -X GET "http://localhost:3000/api/index?year=2019"
✨ Done in 2.19s.
And confirm that the now dev log shows a valid compilation and no errors:
