For this reason we're duplicating the UMD compatible file and giving it that name. */ const source = resolve(process.cwd(), 'dist/color-thief.umd.js'); const dest = resolve(process.cwd(), 'dist/color-thief.min.js'); fs.copyFile(source, dest, (err) => { if (err) throw err; console.log('source.txt was copied to destination.txt'); });
