What happened?

My site works ok with quasar dev run but white screen with quasar build.

DevTools console show:

http://74.48.64.200/spa1001/#/
This site is build with quasar build -d
http://74.48.64.200/vue_src.zip
This is the source code.

[landall]

And which build command can build just the same behavior with quasar dev run?

[landall]

It is an issue about useQuasar() in anonymous function in src/router/index.js.
It works in dev mode but fails in build mode.

import { route } from 'quasar/wrappers'
import { createRouter, createMemoryHistory, createWebHistory, createWebHashHistory } from 'vue-router'
import routes from './routes'

import { useQuasar } from 'quasar';

/*
 * If not building with SSR mode, you can
 * directly export the Router instantiation;
 *
 * The function below can be async too; either use
 * async/await or return a Promise which resolves
 * with the Router instance.
 */

export default route(function (/* { store, ssrContext } */) {
	const createHistory = process.env.SERVER
		? createMemoryHistory
		: (process.env.VUE_ROUTER_MODE === 'history' ? createWebHistory : createWebHashHistory)

	const Router = createRouter({
		scrollBehavior: () => ({ left: 0, top: 0 }),
		routes,

		// Leave this as is and make changes in quasar.conf.js instead!
		// quasar.conf.js -> build -> vueRouterMode
		// quasar.conf.js -> build -> publicPath
		history: createHistory(process.env.VUE_ROUTER_BASE),
	});

	Router.beforeEach((to, from, next) => {
		const $q = useQuasar();
		console.log($q);

		console.log(to, from, next, to.meta.area, to.meta.isMemberArea);
		var isLogined = checkLogin();
		console.log('isLogined=', isLogined);
		if ((to.meta.isMemberArea == true) && (isLogined !== true))
		{
			//$q.localStorage.setItem("preRoute", Router.currentRoute.fullPath);
			localStorage.setItem("preRoute", Router.currentRoute.fullPath);
			next({ path: '/login' });
		}
		else
		{
			//$q.localStorage.remove("preRoute");
			localStorage.removeItem("preRoute");
			next();
		}
	});

	return Router;
});

Not only index.js, all $q.localStorage report TypeError.

please ref: https://quasar.dev/quasar-plugins/web-storage

import { LocalStorage, SessionStorage } from 'quasar'

LocalStorage.set(key, value)
let value = LocalStorage.getItem(key)

SessionStorage.set(key, value)
let value = SessionStorage.getItem(key)

[landall]

sorry, a careless mistake.
there is no setItem but set....

[landall]

It confuses me that the methods are getItem & set in Quasar.LocalStorage but getItem&setItem in Html5.
It also confuses me that It is not broken when I use quasar dev run.

Maybe add a setItem method to be the alias of set is a good choice.

[rstoenescu]

@landall Good point. Added aliases. Will be available in Quasar v2.15.3
