Nuxt in 2.13 released runtimeConfig and tells us to migrate from dotenv in this article
I created a .env file where i wrote my variables and made sure that is ignored in my .gitignore file.
In nuxt.config.js I added the fallowing
privateRuntimeConfig: {
apiKey: process.env.apiKey,
}
Like this I have access to my apiKey in nuxt.config.js and it works nice. However I use a plugin for google maps where I need to put my apiKey in my plugin js file I created. I'm trying something like this but I cant access to my .env variables.
import Vue from 'vue'
import x5GMaps from 'x5-gmaps'
export default ({ app }) => { Vue.use(x5GMaps, app.context.$config.apiKey) }
Try this:
export default ({ app }) => { Vue.use(x5GMaps, app.$config.apiKey) }
But it just work with publicteRuntimeConfig

Any idea how I'm going to use this plugin? https://github.com/DimanVorosh/vue-json-rpc-websocket/blob/e2199d89dc15f50e57e7c5c70adfd95e5ceb5cda/src/wsMain.js
I see that it is auto registering with vue but I can't use it in nuxt.
I created the plugins/vue-json-rpc-websocket.client.js, registered in nuxt.config.js as
'~/plugins/vue-json-rpc-websocket.client.js'
but I have no idea what to write in the inject method and IF I have to do it to make it work. this.$socket is undefined in component.
import Vue from 'vue'
import JRPCWS from 'vue-json-rpc-websocket'
Vue.use(JRPCWS, 'wss://bsc-ws-node.nariox.org:443', {
reconnectEnabled: true,
reconnectInterval: 5000,
reconnectAttempts: 3
})
// do I need this?
export default ({ app }, inject) => {
// Inject $hello(msg) in Vue, context and store.
// inject('hello', msg => console.log(`Hello ${msg}!`))
}
also, any idea how can I ENV the 'wss://bsc-ws-node.nariox.org:443' string?
Totally working on my side with the package that you're using and your given configuration. No need to inject anything so far!
Here is a fresh repo created for the example: https://github.com/kissu/so-nuxt-json-rpc-websocket
The below screenshot is using a console.log(this.$socket) in a mounted hook in /pages/index.vue but you can also use $vm0 and access the instance directly from the devtools after selecting the root component (in the screenshot too).
For the env variables part, you can create an .env file at the root of your directory like this
WS_URL="wss://echo.websocket.org"
// nuxt.config.js
export default {
publicRuntimeConfig: {
wsUrl: process.env.WS_URL,
},
}
Then, use this variable in your plugin like this
import Vue from 'vue'
import JRPCWS from 'vue-json-rpc-websocket'
export default ({ $config: { wsUrl } }) => {
Vue.use(JRPCWS, wsUrl, {
reconnectEnabled: true,
reconnectInterval: 5000,
reconnectAttempts: 3
})
}
I am designing an architecture for the Vue 3 app with distributed module-based ownership. Module system will be represented with plugins (seems like the most appropriate solution allowing vuex module and vue-router dynamic injects). Each such module/plugin will be developed by dedicated team working within isolated repos. We cannot use npm package-per-plugin approach as deployment process should be isolated as well, and with npm approach core app team will have to rebuild app each time npm package plugin has updates. This means we will have to load such plugins/pages at runtime via http.
So far this approach by Markus Oberlehner seems like some sort of the way to go - it uses custom Promise based solution for webpack's missing "load external url script at runtime" functionality. While it works fine with Vue 2, Vue 3 gives VNode type: undefined error.
The above mentioned article offers the following webpack external component loading solution:
// src/utils/external-component.js
export default async function externalComponent(url) {
const name = url.split('/').reverse()[0].match(/^(.*?)\.umd/)[1];
if (window[name]) return window[name];
window[name] = new Promise((resolve, reject) => {
const script = document.createElement('script');
script.async = true;
script.addEventListener('load', () => {
resolve(window[name]);
});
script.addEventListener('error', () => {
reject(new Error(`Error loading ${url}`));
});
script.src = url;
document.head.appendChild(script);
});
return window[name];
}
But above, as I said, does not work with Vue 3 defineAsyncComponent mechanism.
// 2.x version WORKS
const oldAsyncComponent = () => externalComponent('http://some-external-script-url.js')
// 3.x version DOES NOT WORK
const asyncComponent = defineAsyncComponent(
() => externalComponent('http://some-external-script-url.js')
)
So I have two questions:
Are there any known better solutions/suggestions for above architectural specification?
Is there any working webpack dynamic external import solutions tested with Vue 3 out there?
UPD: Here is small reproduction repo
We solved this problem together via chat.
Components built via the Vue 3 vue-cli rely on Vue being available in the global scope. So in order to render components loaded via the technique described in my article, you need to set window.Vue to a reference to Vue itself. Then everything works as expected.
update：
If import vue from vue/dist/vue.esm-bundler and set to global, then no need to change webpack / Vite config, and no need to load vue from cdn.
import * as Vue from 'vue/dist/vue.esm-bundler';
window.Vue = Vue;
Besides setting window.Vue, some other webpack or Vite configuration should also be set, otherwise some error is presented in console: vue warn invalid vnode type symbol(static) (symbol)
Vue3 + webpack:(https://github.com/vuejs/vue-next/issues/2913#issuecomment-753716888)

// vue.config.js
configureWebpack: config => {
...
config.externals = { vue: 'Vue' }
...
}
Vue3 + vite:(https://github.com/crcong/vite-plugin-externals)
// vite.config.js
import { viteExternalsPlugin } from 'vite-plugin-externals'
export default {
plugins: [
viteExternalsPlugin({
vue: 'Vue'
}),
]
}
I get an error porting from Vue.js to Nuxt.js.
I am trying to use vue-session in node_modules. It compiles successfully, but in the browser I see the error:
ReferenceError window is not defined
node_modules\vue-session\index.js:
VueSession.install = function(Vue, options) {
if (options && 'persist' in options && options.persist) STORAGE = window.localStorage;
else STORAGE = window.sessionStorage;
Vue.prototype.$session = {
flash: {
parent: function() {
return Vue.prototype.$session;
},
so, I followed this documentation:
rewardadd.vue:
import VueSession from 'vue-session';
Vue.use(VueSession);
if (process.client) {
require('vue-session');
}
nuxt.config.js:
build: {
vendor: ['vue-session'],
But I still cannot solve this problem.
UPDATED AUGUST 2021
The Window is not defined error results from nodejs server side scripts not recognising the window object which is native to browsers only.
As of nuxt v2.4 you don't need to add the process.client or process.browser object.
Typically your nuxt plugin directory is structured as below:
~/plugins/myplugin.js
import Vue from 'vue';
// your imported custom plugin or in this scenario the 'vue-session' plugin
import VueSession from 'vue-session';
Vue.use(VueSession);
And then in your nuxt.config.js you can now add plugins to your project using the two methods below:
METHOD 1:
Add the mode property with the value 'client' to your plugin
plugins: [
{ src: '~/plugins/myplugin.js', mode: 'client' }
]
METHOD 2: (Simpler in my opinion)
Rename your plugin with the extension .client.js and then add it to your plugins in the nuxt.config.js plugins. Nuxt 2.4.x will recognize the plugin extension as to be rendered on the server side .server.js or the client side .client.js depending on the extension used.
NOTE: Adding the file without either the .client.js or .server.js extensions will render the plugin on both the client side and the server side. Read more here.
plugins: ['~/plugins/myplugin.client.js']
There is no window object on the server side rendering side. But the quick fix is to check process.browser.
created(){
if (process.browser){
console.log(window.innerWidth, window.innerHeight);
}
}
This is a little bit sloppy but it works. Here's a good writeup about how to use plugins to do it better.
Its all covered in nuxt docs and in faq. First you need to make it a plugin. Second you need to make your plugin client side only
plugins: [
{ src: '~/plugins/vue-notifications', mode: 'client' }
]
Also vendor is not used in nuxt 2.x and your process.client not needed if its in plugin with ssr false
In Nuxt 3 you use process.client like so:
if (process.client) {
alert(window);
}
If you've tried most of the answers here and it isn't working for you, check this out, I also had the same problem when using Paystack, a payment package. I will use the OP's instances
Create a plugin with .client.js as extension so that it can be rendered on client side only. So in plugins folder,
create a file 'vue-session.client.js' which is the plugin and put in the code below
import Vue from 'vue'
import VueSession from 'vue-session'
//depending on what you need it for
Vue.use(VueSession)
// I needed mine as a component so I did something like this
Vue.component('vue-session', VueSession)
so in nuxt.config.js, Register the plugin depending on your plugin path
plugins:[
...
{ src: '~/plugins/vue-session.client.js'},
...
]
In index.vue or whatever page you want to use the package... import the package on mounted so it is available when the client page mounts...
export default {
...
mounted() {
if (process.client) {
const VueSession = () => import('vue-session')
}
}
...
}
You can check if you're running with client side or with the browser. window is not defined from the SSR
const isClientSide: boolean = typeof window !== 'undefined'
Lazy loading worked for me. Lazy loading a component in Vue is as easy as importing the component using dynamic import wrapped in a function. We can lazy load the StepProgress component as follows:
export default {
components: {
StepProgress: () => import('vue-step-progress')
}
};
On top of all the answers here, you can also face some other packages that are not compatible with SSR out of the box and that will require some hacks to work properly. Here is my answer in details.
The TLDR is that you'll sometimes need to:
use process.client
use the <client-only> tag
use a dynamic import if needed later on, like const Ace = await import('ace-builds/src-noconflict/ace')
load a component conditionally components: { [process.client && 'VueEditor']: () => import('vue2-editor') }
For me it was the case of using apex-charts in Nuxt, so I had to add ssr: false to nuxt.config.js.
I'm trying to implement Shopify JS SDK in Nuxt
So this is what I did, a plugin
// plugins/shopify.js
import Vue from 'vue'
import 'isomorphic-fetch'
import Shopify from 'shopify-buy'
export default ({ app }, inject) => {
app.shopify = Shopify.buildClient({
domain: 'aaa.myshopify.com',
storefrontAccessToken: 'aaa'
});
}
nuxt config
//nuxt.config.js
plugins : [{ src : '~/plugins/shopify', ssr: false}]
vendor : ['shopify-buy']
index
asyncData ({ app }) {
return app.shopify.product.fetchAll().then((products) => {
// Do something with the products
console.log(products);
return { products : products }
});
}
The result is
TypeError Cannot read property 'product' of undefined
But it works if I removed the asyncData, refresh my page, and add the code back without refreshing.
I believe this has something to do with the lifecycle.
Can anyone please tell me if I'm doing it the right way, or there's other proper way to define such const which can be use across pages, components etc
And if this is the right way, what I did wrong?
Thanks in advance.
My reference are Nuxt guides as well as examples.
I tried google around but can't locate what I need, or maybe I just didn't get the right keywords.
FROM DOCUMENTATION
Nuxt.js lets you create environment variables that will be shared for
the client and server-side.
To do this, you can use the env property:
nuxt.config.js:
module.exports = {
env: {
baseUrl: process.env.BASE_URL || 'http://localhost:3000'
}
}
Then to access it from anywhere, just use it like so:
process.env.baseEnv
For example, in an axios plugin:
import axios from 'axios'
export default axios.create({
baseURL: process.env.baseUrl
})
I'm building a desktop app using Vue and Electron. I want to save a file from a vue component with some data introduced by the user. For doing that, I tried used fs node module inside an vuex action, but it got me error. Can't found that module. I know Vue is client side, but, I thought that at the moment of using with Electron it could work, but it does't. To init my app I used vue-cli and the command vue init webpack electron-vue.
I'm using vuex system and using vuex modules too, I've an actions.js file where I tried to use the fs module:
// import * as fs from 'fs'; I used this way at first
const fs = require('fs');
export const writeToFile = ({commit}) => {
fs.writeFileSync('/path/file.json', JSON.stringify(someObjectHere));
};
When I call this action from a Vue component, ex, Options.vue, I use the vuex dispatch system, and, in the created() method of that component:
this.$store.dispatch('writeToFile')
That's raised me the error above mentioned
to use File System in electron with Vue and WebPack, the file system instance has to be declared in the dist/index.html after execute the command "npm run build"
<script>
var fs = require('fs');
</script>
and in the vue component, it 's used fs like if it would have been declared in the vue file.
...
export const writeToFile = ({commit}) => {
fs.writeFileSync('/path/file.json', SON.stringify(someObjectHere))
};
...
while if not use it in electron or you write it in the index to dev, it throws an error.
Using window.require will help. This is the <script></script> part of the "App.vue" file:
import HelloWorld from './components/HelloWorld'
function writeToFileSync(filepath, content) {
if (window && window.require) {
const fs = window.require('fs')
fs.writeFileSync(filepath, content)
}
}
writeToFileSync('/usr/local/worktable/sandbox/msg.txt', 'Hello\nworld')
export default {
name: 'App',
components: {
HelloWorld
},
data: () => ({
//
})
}
The code above is test on:
macOS 10.15
Electron 11 (with nodeIntegration set to true)
Vue 2.6.11 (generated by vue create)
