The following is my problem.
I packaged my project through vite in library mode. The error occurs whenever my library includes any third party UI library (e.g vue-loading-overlay). But other libraries like moment.js will have no problem.
This is my vite.config.js, Is there any problem with my configuration?
import { defineConfig } from "vite";
import vue from "#vitejs/plugin-vue";
export default defineConfig({
plugins: [vue()],
build: {
lib: {
entry: resolve(__dirname, "src/lib.ts"),
name: "my-ui-lib",
fileName: "my-ui-lib",
},
rollupOptions: {
external: ["vue"],
output: [
{
format: "es",
exports: "named",
globals: { vue: "vue" },
},
],
},
},
});
Finally I resolved my problem, Adding the following in vite.config.js. It works for me.
build: {
/** If you set esmExternals to true, this plugins assumes that
all external dependencies are ES modules */
commonjsOptions: {
esmExternals: true
},
}
Original Answer
"Chart.js V3 is treeshakable so you need to import and register everything or if you want everything you need to import the chart from the auto import like so:
change
import Chart from 'chart.js'
to ->
import Chart from 'chart.js/auto';
For more information about the different ways of importing and using chart.js you can read the integration page in the docs.
Since you are upgrading from Chart.js V2 you might also want to read the migration guide since there are some major breaking changes between V2 and V3"
/* Adding the following in vite.config.js. Just copy and paste all these code. It works for me. */
import { defineConfig } from "vite";
import react from "#vitejs/plugin-react";
// https://vitejs.dev/config/
export default defineConfig({
plugins: [react()],
commonjsOptions: {
esmExternals: true,
},
});
react-pdf v6 has a pretty clever solution for this, look at their entry files. I think the point is to link to the correct file, somehow there's no need to "actually" import the worker (it doesn't run on main thread anyway I guess? New to worker and pdfjs).
import * as pdfjs from 'pdfjs-dist/build/pdf';
pdfjs.GlobalWorkerOptions.workerSrc = new URL('pdfjs-dist/build/pdf.worker.js', import.meta.url);
import.meta availability.
Refer to vuejs 3 documentation to import vue.

Scenario
I'm using Vue2 with Vue CLI as the bundling tool, now I want to migrate Vue CLI to Vite to enhance the development experience, and the migration process is somewhat successful (thanks to this guide).
Problem
Due to a specific reason, I need to keep the production build accessible statically, without any local server required (the web app should run simply by opening up the index.html file on my machine). And with this, I encounter the problem due to the fact that Vite bundles my code in ESM format that has to be served through some server to resolve CORS policy (error screenshot below). And hence the question: Is it possible to configure Vite to build in plain JS rather than ESM?
Any help is appreciated. Thank you.

My vite.config.js as below if it helps:
import path from "path";
import { defineConfig } from "vite";
import { createVuePlugin } from "vite-plugin-vue2";
export default defineConfig({
base: "",
css: {
preprocessorOptions: {
scss: {
additionalData: `
#use "sass:math";
#import "#/scss/utils.scss";`,
},
},
},
plugins: [createVuePlugin()],
resolve: {
extensions: [".mjs", ".js", ".ts", ".jsx", ".tsx", ".json", ".vue"]
alias: {
"#": path.resolve(__dirname, "./src"),
},
},
});
I recently completed a small project in Vue, but when I uploaded it to my server, I am just seeing a blank screen. From my research, I discovered it was likely an issue relating to the asset path as I had it in a sub-directory (https://digitalspaces.dev/portfolio/wil/). After some time trying to fix it by editing the vite.config.js file, I gave up and decided to host it in a subdomain (https://wil.digitalspaces.dev/) instead, where it is now.
The problem is, the index.html now thinks the assets files are at https://digitalspaces.dev/portfolio/wil/assets/, which is true I suppose, but they don't seem to be working from there (nor should they be). Frustratingly, when the build is in https://digitalspaces.dev/assets/, the assets directory is https://digitalspaces.dev/assets/, so it's broken no matter where I have it.
I based my project on the Vue.js quick start guide using vite.
My complete repo is on GitHub, and this is the vite.config.js file:
import { fileURLToPath, URL } from 'url'
import { defineConfig } from 'vite'
import vue from '#vitejs/plugin-vue'
import vueJsx from '#vitejs/plugin-vue-jsx'
// https://vitejs.dev/config/
export default defineConfig({
plugins: [vue(), vueJsx()],
resolve: {
alias: {
'#': fileURLToPath(new URL('./src', import.meta.url))
}
}
})
Thanks to anyone who is able to help.
The subdirectory on your site is /portfolio/wii/, so you should configure the base URL to match:
// vite.config.js
import { defineConfig } from 'vite'
export default defineConfig({
⋮
base: '/portfolio/wii/'
})
I've created a brand new project with npm init vite bar -- --template vue. I've done an npm install web3 and I can see my package-lock.json includes this package. My node_modules directory also includes the web3 modules.
So then I added this line to main.js:
import { createApp } from 'vue'
import App from './App.vue'
import Web3 from 'web3' <-- This line
createApp(App).mount('#app')
And I get the following error:
I don't understand what is going on here. I'm fairly new to using npm so I'm not super sure what to Google. The errors are coming from node_modules/web3/lib/index.js, node_modules/web3-core/lib/index.js, node_modules/web3-core-requestmanager/lib/index.js, and finally node_modules/util/util.js. I suspect it has to do with one of these:
I'm using Vue 3
I'm using Vue 3 Composition API
I'm using Vue 3 Composition API SFC <script setup> tag (but I imported it in main.js so I don't think it is this one)
web3js is in Typescript and my Vue3 project is not configured for Typescript
But as I am fairly new to JavaScript and Vue and Web3 I am not sure how to focus my Googling on this error. My background is Python, Go, Terraform. Basically the back end of the back end. Front end JavaScript is new to me.
How do I go about resolving this issue?
Option 1: Polyfill Node globals/modules
Polyfilling the Node globals and modules enables the web3 import to run in the browser:
Install the ESBuild plugins that polyfill Node globals/modules:
npm i -D #esbuild-plugins/node-globals-polyfill
npm i -D #esbuild-plugins/node-modules-polyfill
Configure optimizeDeps.esbuildOptions to use these ESBuild plugins.
Configure define to replace global with globalThis (the browser equivalent).
import { defineConfig } from 'vite'
import GlobalsPolyfills from '#esbuild-plugins/node-globals-polyfill'
import NodeModulesPolyfills from '#esbuild-plugins/node-modules-polyfill'
export default defineConfig({
⋮
optimizeDeps: {
esbuildOptions: {
2️⃣
plugins: [
NodeModulesPolyfills(),
GlobalsPolyfills({
process: true,
buffer: true,
}),
],
3️⃣
define: {
global: 'globalThis',
},
},
},
})
demo 1
Note: The polyfills add considerable size to the build output.
Option 2: Use pre-bundled script
web3 distributes a bundled script at web3/dist/web3.min.js, which can run in the browser without any configuration (listed as "pure js"). You could configure a resolve.alias to pull in that file:
import { defineConfig } from 'vite'
export default defineConfig({
⋮
resolve: {
alias: {
web3: 'web3/dist/web3.min.js',
},
// or
alias: [
{
find: 'web3',
replacement: 'web3/dist/web3.min.js',
},
],
},
})
demo 2
Note: This option produces 469.4 KiB smaller output than Option 1.
You can avoid the Uncaught ReferenceError: process is not defined error by adding this in your vite config
export default defineConfig({
// ...
define: {
'process.env': process.env
}
})
I found the best solution.
The problem is because you lose window.process variable, and process exists only on node, not the browser.
So you should inject it to browser when the app loads.
Add this line to your app:
window.process = {
...window.process,
};
I have weird problem.
I want use this hover-effect library (https://github.com/robin-dela/hover-effect) in my nuxt project.
This i have in my contact.vue in script tags
import hoverEffect from 'hover-effect'
export default {
mounted() {
const effect = new hoverEffect({
parent: document.querySelector('.right-section'),
intensity: 0.3,
image1: require('#/assets/images/1.jpg'),
image2: require('#/assets/images/2.jpg'),
displacementImage: require('#/assets/images/dist2.jpg'),
})
},
}
And that effect works perfectly.. BUT when i refresh the page i got this error:
SyntaxError Cannot use import statement outside a module
So i tried add this plugin into plugins/hover-effect.js
import Vue from 'vue'
import hoverEffect from 'hover-effect'
Vue.use(hoverEffect)
then in nuxt.config.js
plugins: [{ src: '~/plugins/hover-effect', mode: 'client' }],
But nothing works.. its always error: hoverEffect is not defined. I tried another 20 ways with no success. I tried this effect in normal Vue project and it works but not in nuxt.js. Can somebody help me with this?
You can configure it in the head of the page:
Page.vue
export default {
head() {
return {
script: [
{src: '../dist/hover-effect.umd.js'}
]
}
},
...
mounted() {
const effect = new hoverEffect({
parent: document.querySelector('.right-section'),
intensity: 0.3,
image1: require('#/assets/images/1.jpg'),
image2: require('#/assets/images/2.jpg'),
displacementImage: require('#/assets/images/dist2.jpg'),
})
},
modules: [
// Doc: https://axios.nuxtjs.org/usage
'#nuxtjs/axios',
// Doc: https://github.com/nuxt/content
'#nuxt/content',
'hover-effect'
],
Have you tried to add hover-effect library to modules in nuxt.config.js file? All I did was install the package and add it to the module and then have the same code as your script tag. Hope it helped you!
I struggle to add a plugin in Nuxt.js. I have been looking to the doc and all kind of similar problems, but I got the same error: simpleParallax is not defined.
I tried different approach on all files
nuxt.config.js:
plugins: [
{src: '~/plugins/simple-parallax.js', mode:'client', ssr: false}
],
plugins/simple-parallax.js:
import Vue from 'vue';
import simpleParallax from 'simple-parallax-js';
Vue.use(new simpleParallax);
index.vue:
Export default {
plugins: ['#/plugins/simple-parallax.js'],
mounted() {
var image = document.getElementsByClassName('hero');
new simpleParallax(image, {
scale: 1.8
});
}
}
Error message:
ReferenceError: simpleParallax is not defined.
The best solution I found out so far is to register simpleParallax on the Vue prototype like so in a plugin nuxt file with the name simple-parallax.client.js:
import Vue from 'vue';
import simpleParallax from 'simple-parallax-js';
Vue.prototype.$simpleParallax = simpleParallax;
Also my nuxt.config.js file if anyone would like to verify that as well:
plugins: [
{src: '~/plugins/simple-parallax.client.js', mode: 'client', ssr: false}
],
I then have access to the plugin before instantiation in my case in the mounted life cycle of the primary or root component to grab the desired HTML elements and instantiate their individual parallax with the newly added global method this.$simpleParallax
For example I can then intiate a certain HTML element to have its parallax like so:
const someHTMLElement = document.querySelectorAll('.my-html-element');
const options = {...} // your desired parallax options
new this.$simpleParallax(someHTMLElement, options);
Actually you don't need to use plugin here.
Just import simpleParallax from 'simple-parallax-js' in your component and init it with your image in mounted hook.
index.vue:
import simpleParallax from 'simple-parallax-js'
export default {
...
mounted() {
// make sure this runs on client-side only
if (process.client) {
var image = document.getElementsByClassName('thumbnail')
new simpleParallax(image)
}
},
...
}
And don't forget to remove previously created plugin, it's redundant here.
