Can't load Expo Vector Icons in Nextjs

I have tried a lot of different ways to do this, with absolutely zero luck, over multiple days.
I am trying to use Solito Nativebase Universal Typescript repo to do this:
https://github.com/GeekyAnts/nativebase-templates/tree/master/solito-universal-app-template-nativebase-typescript
I have read, and tried everything on this page at least a dozen times:
https://github.com/GeekyAnts/nativebase-templates/issues/43
My current next.config.js file looks like this:
/** #type {import('next').NextConfig} */
const { withNativebase } = require('#native-base/next-adapter')
const withImages = require('next-images')
const { withExpo } = require('#expo/next-adapter')
const withFonts = require('next-fonts')
module.exports = withNativebase({
dependencies: [
'#expo/next-adapter',
'next-images',
'react-native-vector-icons',
'react-native-vector-icons-for-web',
'solito',
'app',
],
plugins: [
[withFonts, { projectRoot: __dirname }],
withImages,
[withExpo, { projectRoot: __dirname }],
],
nextConfig: {
images: {
disableStaticImages: true,
},
projectRoot: __dirname,
reactStrictMode: true,
webpack5: true,
webpack: (config, options) => {
config.resolve.alias = {
...(config.resolve.alias || {}),
'react-native$': 'react-native-web',
'#expo/vector-icons': 'react-native-vector-icons',
}
config.resolve.extensions = [
'.web.js',
'.web.ts',
'.web.tsx',
...config.resolve.extensions,
]
return config
},
},
})
I have also tried using #native-base/icons, again, no luck.
My end use case is this:
export const Cart = (props: IIconStyles) => {
return (
<Icon
as={FontAwesome5}
name="shopping-cart"
size={props.size ? props.size : 6}
color="gray.200"
/>
)
Theoretically it SHOULD show a shopping cart, but instead, this is what I see:
So clearly there's some font issue or other issue that is preventing it from loading in the actual SVG.
I can't figure out what this is - I've tried rewriting my _document.tsx file like this:
https://docs.nativebase.io/nb-icons
I've tried adding this to my next.config.js:
config.module.rules.push({
test: /\.ttf$/,
loader: "url-loader", // or directly file-loader
include: path.resolve(__dirname, "node_modules/#native-base/icons"),
});
When I try to do something like this:
import fontsCSS from '#native-base/icons/FontsCSS';
in my _document.tsx file, I get the following error:
Module not found: Can't resolve '#native-base/icons/lib/FontsCSS'
Despite the fact that I've got #native-base/icons installed in my package.json, as well as having it in my Babel file per the instruction link above.
How do I get vector icons to work in Next?
Note, this is specifically Next/Expo/React Native

You can read more about setup of next-adapter-icons here.
I got it working with following approach,
next.config.js
const { withNativebase } = require("#native-base/next-adapter");
const path = require("path");
module.exports = withNativebase({
dependencies: ["#native-base/icons", "react-native-web-linear-gradient"],
nextConfig: {
webpack: (config, options) => {
config.module.rules.push({
test: /\.ttf$/,
loader: "url-loader", // or directly file-loader
include: path.resolve(__dirname, "node_modules/#native-base/icons"),
});
config.resolve.alias = {
...(config.resolve.alias || {}),
"react-native$": "react-native-web",
"react-native-linear-gradient": "react-native-web-linear-gradient",
"#expo/vector-icons": "react-native-vector-icons",
};
config.resolve.extensions = [
".web.js",
".web.ts",
".web.tsx",
...config.resolve.extensions,
];
return config;
},
},
});
pages/_document.js
import React from 'react';
import { DocumentContext, DocumentInitialProps } from 'next/document';
import { default as NativebaseDocument } from '#native-base/next-adapter/document'
// Icon Font Library Imports
import MaterialIconsFont from '#native-base/icons/FontsCSS/MaterialIconsFontFaceCSS';
import EntypoFontFaceCSS from '#native-base/icons/FontsCSS/EntypoFontFaceCSS';
const fontsCSS = `${MaterialIconsFont} ${EntypoFontFaceCSS}`;
export default class Document extends NativebaseDocument {
static async getInitialProps(ctx) {
const props = await super.getInitialProps(ctx);
const styles = [
<style key={'fontsCSS'} dangerouslySetInnerHTML={{ __html: fontsCSS }} />,
...props.styles,
]
return { ...props, styles: React.Children.toArray(styles) }
}
}
pages/index.tsx
import React from "react";
import { Box, Icon } from "native-base";
import Entypo from "#expo/vector-icons/Entypo";
export default function App() {
return (
<Box>
<Icon
as={Entypo}
name="user"
color="coolGray.800"
_dark={{
color: "warmGray.50",
}}
/>
</Box>
);
}

Using import like this:
import MaterialIcons from '#expo/vector-icons/MaterialIcons'
in place of:
import { MaterialIcons } from '#expo/vector-icons'
worked for me. I think this is because of the way babel/webpack handles imports in the template. I followed the steps here to setup the icons.
Here's what that looks like on web:

How to use Vue 3 Meta with Vue.js 3?

It seems that Vue Meta has been upgraded to handle Vue.js 3 with a new npm package called vue-3-meta
Before Vue.js 3, it was easy to use vue-meta by adding it to the Vue instance:
import Vue from 'vue'
import VueMeta from 'vue-meta'
Vue.use(VueMeta, {
// optional pluginOptions
refreshOnceOnNavigation: true
})
However in Vue.js 3, there is no Vue instance; and instead you create the app by running createApp like such:
const app = createApp(App);
const router = createVueRouter();
app.use(router);
// need to make app use Vue-Meta here
I cannot find any documentation for vue-3-meta. import VueMeta from 'vue-meta' no longer works.
How do I import the vue-3-meta plugin properly and use it with app like in prior versions?

Disclaimer: vue-meta v3 is still in alpha!
This was the minimal implementation I needed to get started:
Update vue-meta to v3 (in package.json)
- "vue-meta": "^2.4.0",
+ "vue-meta": "^3.0.0-alpha.7",
...or with yarn:
yarn add vue-meta#alpha
Add metaManager to Vue app
import { createMetaManager } from 'vue-meta'
const app = createApp(App)
.use(router)
.use(store)
.use(createMetaManager()) // add this line
await router.isReady()
app.mount('#app')
Add <metainfo> to App.vue <template> (this is also where I set a "title template")
<template>
<metainfo>
<template v-slot:title="{ content }">{{ content ? `${content} | SITE_NAME` : `SITE_NAME` }}</template>
</metainfo>
<header />
<router-view />
<footer />
</template>
Set default meta in App.vue <script>
Vue 3 vanilla:
import { useMeta } from 'vue-meta'
export default {
setup () {
useMeta({
title: '',
htmlAttrs: { lang: 'en', amp: true }
})
}
}
or with vue-class-component:
import { setup, Vue } from 'vue-class-component'
import { useMeta } from 'vue-meta'
export default class App extends Vue {
meta = setup(() => useMeta({
title: '',
htmlAttrs: { lang: 'en', amp: true }
})
}
Override meta in each component
Vue 3 vanilla:
import { useMeta } from 'vue-meta'
export default {
setup () {
useMeta({ title: 'Some Page' })
}
}
or with vue-class-component:
import { computed } from '#vue/runtime-core'
import { setup, Vue } from 'vue-class-component'
import { useMeta } from 'vue-meta'
export default class SomePage extends Vue {
meta = setup(() => useMeta(
computed(() => ({ title: this.something?.field ?? 'Default' })))
)
}

"Quick Usage" (vue-meta next branch)
Vue Router Example (vue-meta next branch)

In addition to the previous answers, I also needed to add a transpileDependency in my vue.config.js, as I was using vue-cli:
module.exports = {
transpileDependencies: ['vue-meta']
}
Else, I would get the error:
error in ./node_modules/vue-meta/dist/vue-meta.esm-browser.min.js
Module parse failed: Unexpected token (8:7170)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
Thanks to this thread for pointing me to this: https://stackoverflow.com/a/65844988/3433137

metaManager is a MetaManager instance created from createMetaManager() of vue-meta.
Based on the Vue 3 + Vue Router example for vue-meta, here's an example usage:
import { createApp } from 'vue'
import { createMetaManager, defaultConfig, resolveOption, useMeta } from 'vue-meta'
const decisionMaker5000000 = resolveOption((prevValue, context) => {
const { uid = 0 } = context.vm || {}
if (!prevValue || prevValue < uid) {
return uid
}
})
const metaManager = createMetaManager({
...defaultConfig,
esi: {
group: true,
namespaced: true,
attributes: ['src', 'test', 'text']
}
}, decisionMaker5000000)
useMeta(
{
og: {
something: 'test'
}
},
metaManager
)
createApp(App).use(metaManager).mount('#app')

Using vue-i18n to translate the default value for a Vue component prop

I'm using vue-i18n to handle localization in my app. I need to apply localization to the default value for a component prop:
export default {
name: 'ExampleComponent',
props: [{
prompt: {
required: false,
type: String,
default: $t('example.prompt.default')
}]
}
$t is obviously not in scope as shown, but it seems that at the point the default value for the prop is being evaluated, this is not the component itself either, so this.$t is also undefined.
What's the best way to use VueI18n to translate the default value for a prop?

You can access $t in a callback function as the callback is evaluated in the context of the created component.
prompt: {
required: false,
type: String,
default: function () {
this.$t('example.prompt.default')
}
}
The downside here is that the value will be undefined in the beforeCreate life-cycle hook. If you need it there, then your best bet is to instead set the default value to the key of your i18n definition (example.prompt.default), and use this.$t(this.prompt) instead.

You can import the VueI18n instance from where you imported it.
import i18n from '../i18n'
export default {
name: 'ExampleComponent',
props: [{
prompt: {
required: false,
type: String,
default: i18n.t('example.prompt.default')
}]
}
i18ns.js
import Vue from 'vue'
import VueI18n from 'vue-i18n'
Vue.use(VueI18n)
function loadLocaleMessages () {
const locales = require.context('./locales', true, /[A-Za-z0-9-_,\s]+\.json$/i)
const messages = {}
locales.keys().forEach(key => {
const matched = key.match(/([A-Za-z0-9-_]+)\./i)
if (matched && matched.length > 1) {
const locale = matched[1]
messages[locale] = locales(key)
}
})
return messages
}
export default new VueI18n({
locale: process.env.VUE_APP_I18N_LOCALE || 'en',
fallbackLocale: process.env.VUE_APP_I18N_FALLBACK_LOCALE || 'en',
messages: loadLocaleMessages()
})

Vue router - how to have multiple components loaded on the same route path based on user role?

I have app where user can login in different roles, eg. seller, buyer and admin.
For each user I'd like to show dashboard page on the same path, eg. http://localhost:8080/dashboard
However, each user will have different dashboard defined in different vue components, eg. SellerDashboard, BuyerDashboard and AdminDashboard.
So basically, when user opens http://localhost:8080/dashboard vue app should load different component based on the user role (which I store in vuex). Similarly, I'd like to have this for other routes. For example, when user goes to profile page http://localhost:8080/profile app should show different profile component depending on the logged in user.
So I'd like to have the same route for all users roles as opposed to have different route for each user role, eg. I don't want user role to be contained in url like following: http://localhost:8080/admin/profile and http://localhost:8080/seller/profile etc...
How can I implement this scenario with vue router?
I tried using combination of children routes and per-route guard beforeEnter to resolve to a route based on user role. Here is a code sample of that:
in router.js:
import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'
import store from '#/store'
Vue.use(VueRouter)
const routes = [
{
path: '/',
name: 'home',
component: Home,
beforeEnter: (to, from, next) => {
next({ name: store.state.userRole })
},
children: [
{
path: '',
name: 'admin',
component: () => import('#/components/Admin/AdminDashboard')
},
{
path: '',
name: 'seller',
component: () => import('#/components/Seller/SellerDashboard')
},
{
path: '',
name: 'buyer',
component: () => import('#/components/Buyer/BuyerDashboard')
}
]
},
]
const router = new VueRouter({
mode: 'history',
base: process.env.BASE_URL,
routes
})
export default router
in store.js:
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
state: {
userRole: 'seller' // can also be 'buyer' or 'admin'
}
})
App.vue contains parent router-view for top-level routes, eg. map / to Home component and /about to About component:
<template>
<router-view/>
</template>
<script>
export default {
name: 'App',
}
</script>
And Home.vue contains nested router-view for different user's role-based components:
<template>
<div class="home fill-height" style="background: #ddd;">
<h1>Home.vue</h1>
<!-- nested router-view where user specific component should be rendered -->
<router-view style="background: #eee" />
</div>
</template>
<script>
export default {
name: 'home'
}
</script>
But it doesn't work because I get Maximum call stack size exceeded exception in browser console when I call next({ name: store.state.userRole }) in beforeEnter. The exception is:
vue-router.esm.js?8c4f:2079 RangeError: Maximum call stack size exceeded
at VueRouter.match (vue-router.esm.js?8c4f:2689)
at HTML5History.transitionTo (vue-router.esm.js?8c4f:2033)
at HTML5History.push (vue-router.esm.js?8c4f:2365)
at eval (vue-router.esm.js?8c4f:2135)
at beforeEnter (index.js?a18c:41)
at iterator (vue-router.esm.js?8c4f:2120)
at step (vue-router.esm.js?8c4f:1846)
at runQueue (vue-router.esm.js?8c4f:1854)
at HTML5History.confirmTransition (vue-router.esm.js?8c4f:2147)
at HTML5History.transitionTo (vue-router.esm.js?8c4f:2034)
and thus nothing is rendered.
Is there a way I can solve this?

You might want to try something around this solution:
<template>
<component :is="compName">
</template>
data: () {
return {
role: 'seller' //insert role here - maybe on `created()` or wherever
}
},
components: {
seller: () => import('/components/seller'),
admin: () => import('/components/admin'),
buyer: () => import('/components/buyer'),
}
Or if you prefer maybe a bit more neat (same result) :
<template>
<component :is="loadComp">
</template>
data: () => ({compName: 'seller'}),
computed: {
loadComp () {
const compName = this.compName
return () => import(`/components/${compName}`)
}
}
This will give you the use of dynamic components without having to import all of the cmps up front, but using only the one needed every time.

Such code retrieves component code only for a given role:
import Vue from "vue";
import VueRouter from "vue-router";
import Home from "../views/Home.vue";
import store from "../store";
Vue.use(VueRouter);
const routes = [
{
path: "/",
name: "home",
component: () => {
switch (store.state.userRole) {
case "admin":
return import("../components/AdminDashboard");
case "buyer":
return import("../components/BuyerDashboard");
case "seller":
return import("../components/SellerDashboard");
default:
return Home;
}
}
}
];
const router = new VueRouter({
mode: "history",
base: process.env.BASE_URL,
routes
});
export default router;

One approach would be to use a dynamic component. You could have a single child route whose component is also non-specific (e.g. DashboardComponent):
router.js
const routes = [
{
path: '/',
name: 'home',
children: [
{
path: '',
name: 'dashboard',
component: () => import('#/components/Dashboard')
}
]
}
]
components/Dashboard.vue
<template>
<!-- wherever your component goes in the layout -->
<component :is="dashboardComponent"></component>
</template>
<script>
import AdminDashboard from '#/components/Admin/AdminDashboard'
import SellerDashboard from '#/components/Seller/SellerDashboard'
import BuyerDashboard from '#/components/Buyer/BuyerDashboard'
const RoleDashboardMapping = {
admin: AdminDashboard,
seller: SellerDashboard,
buyer: BuyerDashboard
}
export default {
data () {
return {
dashboardComponent: RoleDashboardMapping[this.$store.state.userRole]
}
}
}
</script>

You run into the Maximum call stack size exceeded exception because the next({ name: store.state.userRole }) will trigger another redirection and call the beforeEnter again and thus results in infinite loop.
To solve this, you can check on the to param, and if it is already set, you can call next() to confirm the navigation, and it will not cause re-direction. See code below:
beforeEnter: (to, from, next) => {
// Helper to inspect the params.
console.log("to", to, "from", from)
// this is just an example, in your case, you may need
// to verify the value of `to.name` is not 'home' etc.
if (to.name) {
next();
} else {
next({ name: store.state.userRole })
}
},

I faced the same problem (I use Meteor JS with Vue JS) and I found the way to do it with the render function to load different components on the same route. So, in your case it should be:
import Vue from "vue";
import VueRouter from "vue-router";
import Home from "../views/Home.vue";
import AdminDashboard from "../components/AdminDashboard";
import BuyerDashboard from "../components/BuyerDashboard";
import SellerDashboard from "../components/SellerDashboard";
import store from "../store";
Vue.use(VueRouter);
const routes = [
{
path: "/",
name: "home",
component: {
render: (h) => {
switch (store.state.userRole) {
case "admin":
return h(AdminDashboard);
case "buyer":
return h(BuyerDashboard);
case "seller":
return h(SellerDashboard);
default:
return h(Home);
}
}
}
}
];
const router = new VueRouter({
mode: "history",
base: process.env.BASE_URL,
routes
});
export default router;
Note that this solution also works but only for the first time, if you enter again to that route, the last component loaded it will keep (you will need to reload the page). So, with the render function it always load the new component.

Vue Router 4 (Vue 3)
If you are using Vue Router 4 (usable only with Vue 3), one alternative solution is to use dynamic routing
This new feature allows us to remove/add routes on the fly.
// router.js
import { createRouter, createWebHistory } from 'vue-router'
import store from "../store";
import Home from "../views/Home.vue";
import About from "../views/About.vue";
// all routes independent of user role
const staticRoutes = [
{
path: "/",
name: "home",
component: Home,
},
{
path: "/about",
name: "about",
component: About,
},
]
const getRoutesForRole = (role) => {
// imlementation can vary - see the rest of the answer
}
// routes used at app initialization
const initialRoutes = [...staticRoutes, ...getRoutesForRole(store.state.userRole)]
const router = createRouter({
history: createWebHistory(),
routes: initialRoutes,
})
export default router
export const updateRoutesForRole = () {
// implementation can vary - see the rest of the answer
}
How to generate dynamic routes - getRoutesForRole
The implementation of course depends on many factors - how many routes (and also roles) do you have is probably most important.
With just 2 or 3 routes (and not many roles) it is just fine to use a static definition:
const routesPerRole = {
"admin": [
{
path: "/dashboard",
name: "dashboard",
component: () => import("../components/AdminDashboard.vue")
}, // more routes follow....
],
"seller": [
{
path: "/dashboard",
name: "dashboard",
component: () => import("../components/SellerDashboard.vue")
}, // more routes follow....
],
"buyer": [
{
path: "/dashboard",
name: "dashboard",
component: () => import("../components/BuyerDashboard.vue")
}, // more routes follow....
],
}
const getRoutesForRole = (role) => {
if(!role) return []
return routesPerRole[role]
}
If you have many routes and/or many roles, you probably want something more generic. First we need some good naming convention - for example lets say that we will organize our components in a directory structure like this: #/components/${role}/${componentName}.vue
Then we can use Webpacks dynamic import
const routeTemplates = [
{
path: "/dashboard",
name: "dashboard",
component: 'Dashboard'
},
]
const getRoutesForRole = (role) => {
if(!role) return []
const routesForRole = routeTemplates.map(route => ({
...route,
component: () => import(`#/components/${role}/${route.component}.vue`)
}))
return routesForRole
}
Note that thanks to how import() with dynamic expression works in Webpack this will make Webpack to create new JS chunk for each component in #/components folder which may be not what you want.
Easy fix is to move the "role dependent" components into it's own subfolder so instead of using #/components/admin/.... just use #/components/perRoleComponents/admin/.... and
import(`#/components/perRoleComponents/${role}/${route.component}.vue`)
Other solution is to use different import() statement for each role. This will also allow us to use Webpacks "magic comments" and for example force Webpack to pack all components for each role into single js chunk:
const routeTemplates = [
{
path: "/dashboard",
name: "dashboard",
component: 'Dashboard'
},
]
const getComponentLoader = (role, componentName) => {
switch(role) {
"admin": return () => import(
/* webpackChunkName: "admin-components" */
/* webpackMode: "lazy-once" */
`#/components/admin/${componentName}.vue`)
"seller": return () => import(
/* webpackChunkName: "seller-components" */
/* webpackMode: "lazy-once" */
`#/components/seller/${componentName}.vue`)
"buyer": return () => import(
/* webpackChunkName: "buyer-components" */
/* webpackMode: "lazy-once" */
`#/components/buyer/${componentName}.vue`)
}
}
const getRoutesForRole = (role) => {
if(!role) return []
const routesForRole = routeTemplates.map(route => ({
...route,
component: getComponentLoader(role, route.component)
}))
return routesForRole
}
How to update routes - updateRoutesForRole()
Easiest scenario is when each role has same set of routes and just wants to use a different component. In this case to switch the routes when role changes we can just use addRoute
Add a new route record to the router. If the route has a name and there is already an existing one with the same one, it removes it first.
export const updateRoutesForRole = () {
const role = store.state.userRole
const routesForRole = getRoutesForRole(role)
routesForRole.forEach(r => router.addRoute(r))
}
For more complicated scenarios where not all routes are available for all roles, previous routes (for previous active role - if any) must be removed 1st using removeRoute function. Also our getRoutesForRole() must be different. One solution is to use route meta fields
const routeTemplates = [
{
path: "/dashboard",
name: "dashboard",
component: 'Dashboard',
meta: { forRoles: ['admin', 'seller'] }
},
]
const getRoutesForRole = (role) => {
if(!role) return []
const routesForRole = routeTemplates
.filter(route => route.meta?.forRoles?.includes(role))
.map(route => ({
...route,
component: () => import(`#/components/${role}/${route.component}.vue`)
}))
return routesForRole
}
export const updateRoutesForRole = () {
const role = store.state.userRole
// delete previous 1st
router.getRoutes()
.filter(route => route.meta?.forRoles)
.forEach(route => router.removeRoute(route.name))
const routesForRole = getRoutesForRole(role)
routesForRole.forEach(r => router.addRoute(r))
}
Router v3 (for Vue 2)
Note that Router v3 (and earlier) was never designed with dynamic routing in mind. There is no removeRoute() function. There is a addRoute() so some of the scenarios described above could be probably possible but it currently (Router v3.5.3) does not work as described in the documentation

One way to solve this is to create three separate components DashboardForAdmin, DashBoardForSeller, and DashBoardForBuyer for three types of users.
Then use a mixin.js
export default {
data: function () {
return {
userType : "buyer"; // replace this with a function that returns "seller", "buyer", or "admin"
}
}
}
Create a Vue component DashboardContainer renders the correct dashboard component based on mixin return value
<template>
<div>
<div v-if="userType === 'admin'">
<DashboardForAdmin />
</div>
<div v-else-if="userType === 'buyer'">
<DashboardForBuyer />
</div>
<div v-else>
<DashboardForSeller />
</div>
</div>
</template>
<script>
import mixin from '#/mixin.js';
import DashboardForAdmin from '#/components/DashboardForAdmin.vue';
import DashBoardForSeller from '#/components/DashBoardForSeller.vue';
import DashBoardForBuyer from '#/components/DashBoardForBuyer.vue';
export default {
mixins: [mixin],
components: {
DashboardForAdmin, DashBoardForSeller, DashBoardForBuyer
},
};
</script>
Now you can add a single route for the DashboardContainer

Access Nuxt.js context in Vue plugin

I'm using Nuxt.js and I have two plugins installed.
I need access to the VueI18n instance from lang.js in validate.js
Does someone know how to do this?
lang.js
Vue.use(VueI18n)
export default ({ app }) => {
app.i18n = new VueI18n({
locale: 'en',
messages
})
}
validate.js
Vue.use(VeeValidate, {
i18nRootKey: 'validations',
i18n, // access the VueI18n instance from plugin above
dictionary: {
en: validationMessages
}
})
export default ({ app }) => {
// This way I could get the instance but how to add it to the plugin?
console.log(app.i18n)
}

Just move your vue.use inside export default
export default ({ app }) => {
Vue.use(VeeValidate, {
i18nRootKey: 'validations',
i18n: app.i18n, // access the VueI18n instance from plugin above
dictionary: {
en: validationMessages
}
})
}
