}
Additional knowledge: When packaging under vue, select several files to package 1 file and do lazy loading
Direct code
const DeviceManage = r => require.ensure([], () => r(require(deviceManagePath + 'main/DeviceManage')), 'g-DeviceManage');
const SingleDeviceSet = r => require.ensure([], () => r(require(deviceManagePath + 'deviceSet/SingleDeviceSet')), 'g-DeviceManage');
const ModifyNo = r => require.ensure([], () => r(require(deviceManagePath + 'modifyNo/ModifyNo')), 'g-DeviceManage');
const PricePerTime = r => require.ensure([], () => r(require(deviceManagePath + 'pricePerTime/PricePerTime')), 'g-DeviceManage');
const SetParams = r => require.ensure([], () => r(require(deviceManagePath + 'setParams/SetParams')), 'g-DeviceManage');
const ShowDevicePrice = r => require.ensure([], () => r(require(deviceManagePath + 'showDevicePrice/ShowDevicePrice')), 'g-DeviceManage');
const parameterSetting = r => require.ensure([], () => r(require(deviceManagePath + 'parameterSetting/parameterSetting')), 'g-DeviceManage');
const SetParams3G = r => require.ensure([], () => r(require(deviceManagePath + 'setParams3G/SetParams3G')), 'g-Device3Gparams');
In this way, all g-DeviceManage files will be packaged in 1 file
