Options

web.transformImportExport

Enabling this option will allow your project to run with older JavaScript syntax (i.e. module.exports). This option will break tree shaking and increase your bundle size, but will eliminate the following error when module.exports is used:

TypeError: Cannot assign to read only property 'exports' of object '#<Object>'

default: false
