When using certain build systems (TSC, for example), transpilation of ESM to CommonJS will expect there to always be a default property.
import copy from 'fast-copy';
// becomes
const copy = require('fast-copy').default;
This causes it to fail because there is no default property with the CommonJS usage (it is simply module.exports = copy;). This was raised in #37 .
Change
Add a circular reference manually as the default property.
copy.default = copy;
This manual forging of an ESM-like module allows those transpilers to work as expected without forcing a breaking change of normal CommonJS usage of the library.
