The package linked to from here is now pure ESM. It cannot be require()
'd from CommonJS.
This means you have the following choices:
- Use ESM yourself. (preferred)
Useimport foo from 'foo'
instead ofconst foo = require('foo')
to import the package. You also need to put"type": "module"
in your package.json and more. Follow the below guide. - If the package is used in an async context, you could use
await import(…)
from CommonJS instead ofrequire(…)
. - Stay on the existing version of the package until you can move to ESM.
