I get an error when I run the program (vue3 + elements plus), but I don't know what's wrong with it. please help me.
Here is the error description and picture:
56:23 error Parsing error: Unexpected token, expected "," (11:23)

In the current configuration, eslint cannot deal with TypeScript. The following steps enable TypeScript support.
Run npm install --save-dev #vue/eslint-config-typescript
Adapt the ESLint config:
Remove "parser": "#babel/eslint-parser" from the parserOptions
Add "#vue/typescript/recommended" to the extends key
Based on your file above, it would look like this:
{
"root": true,
"env": {
"node": true
},
"extends": [
"plugin:vue/essential",
"eslint:recommended",
"#vue/typescript/recommended"
],
"parserOptions": {},
"rules": {}
}
Depending on your ESLint version, the installation of #vue/eslint-config-typescript might result in a dependency conflict. With ESLint < 9 you'll have to install #vue/eslint-config-typescript#10
If Code Works Then You need to configure esLint if it throw an error then u need to place correctlly place it between {}

I am new to Vue.js and I am having an issue and have been stuck for a long while trying different fixes.
After starting a dev server using npm run serve, I would expect that when I make changes to any .vue or .js files within my directory, the server would refresh and display these changes. However, no matter what I try nothing happens. Nothing is compiling and nothing changes within my terminal. The only way I can refresh the server is by closing it and running a new one. Refreshing my browser page does nothing either. Really stumped on this one so will be eternally grateful if anyone can help as none of the fixes I found on here have worked for me :(
My vue.config.js is as follows:
const { defineConfig } = require('#vue/cli-service')
module.exports = defineConfig({
transpileDependencies: true,
devServer: {
client: {
progress: true
},
hot: false,
watchFiles: {
paths: ['src/**/*.js', 'src/**/*.vue', 'src/**/*.json', 'src/views/*.vue']
},
liveReload: true,
}
})
My package.json is:
{
"name": "product-and-cart",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
},
"dependencies": {
"core-js": "^3.8.3",
"nodemon": "^2.0.19",
"vue": "^3.2.13",
"vue-router": "^4.0.3"
},
"devDependencies": {
"#babel/core": "^7.12.16",
"#babel/eslint-parser": "^7.12.16",
"#vue/cli-plugin-babel": "~5.0.0",
"#vue/cli-plugin-eslint": "~5.0.0",

"eslint-plugin-import": "^2.25.3",
"eslint-plugin-node": "^11.1.0",
"eslint-plugin-promise": "^5.1.0",
"eslint-plugin-vue": "^8.0.3",
"sass": "^1.54.5",
"sass-loader": "^13.0.2",
"webpack": "^5.74.0"
},
"eslintConfig": {
"root": true,

},

"plugin:vue/vue3-essential",

],
"parserOptions": {
"parser": "#babel/eslint-parser"
},
"rules": {}
},
"browserslist": [
"> 1%",
"last 2 versions",
"not dead",
"not ie 11"
]
}
And my jsconfig.json is:
{
"compilerOptions": {
"target": "es5",
"module": "esnext",
"baseUrl": "./",
"moduleResolution": "node",
"paths": {
"#/*": [
"src/*"
]
},
"lib": [
"esnext",
"dom",
"dom.iterable",
"scripthost"
],
"jsx": "preserve"
}
}
And babel.config.js:
module.exports = {
presets: [
'#vue/cli-plugin-babel/preset'
]
}
In your vue.config.js file, you set hot module replacement to false in devServer configuration; therefore, your changes won't be applied without refreshing the page. Hot module replacement is enabled by default in Vue CLI, you can remove hot from the configuration. Also, you don't have to set liveReload and watch options for this.
For more details, you can take a look at Vue CLI configuration and Webpack DevServer configuration.
I'm trying to debug vuejs with vscode, I've tried a lot of tutorials/answers and could not make it work.
So I decided to ask a question here, maybe nowadays there's a right way to make it work.
I've created a project that it's identical with the one I want to debug, so I can post prints here.
The project structure is:

UPDATE
#A.D asked if I've tried to use keyword
debugger;
Here is the results:
Ps: I don't want to start writing debugger in my code...
But with that i could see that the debugger file is pointing to:
C:\Users\vinic\Desktop\test\test\js\webpack:\test\src\components\HelloWorld.vue
But the component src is actualy located in
C:\Users\vinic\Desktop\test\test\src\components\HelloWorld.vue
Why my breakpoints are not bounding?
Try to change webRoot param and leave as in the documentation, you need to include src after ${workspaceFolder}.
{
"type": "chrome",
"request": "launch",
"name": "vuejs: chrome",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}/src",
"breakOnLoad": true,
"sourceMapPathOverrides": {
"webpack:///src/*": "${webRoot}/*"
}
}
UPDATE:
After some research, i found this issue.
There is a change in this version that you used.
They changed the compiler and this affected the way to debugger.
You can use the "2.6.11" works in this version.
Note: This change affected later versions.
Appearently there are some problems with the webpack of vue versions above 2.6.11

Failed to load plugin 'vue' declared in 'package.json': Package subpath './lib/rules/array-bracket-spacing' is not defined by "exports" in C:\Users\<my_username>\FolderX\Subfolder\<appname>\eslint\package.json
Referenced from: C:\Users\<my_username>\FolderX\Subfolder\<appname>\package.json
That's the error I'm getting every time I npm run serve I've upated eslint, added prettier and fixed most of my vulnerability problems, and it still persists. I've combed the eslint issues on github and there is nothing like this, some issues are similar but they refer to eslintrc. Nothing is matching this exactly. I should mention that the app itself is very small and simple. It was supposed to be the start of a project but when I was adding views to the project, this happened.

Any help would be greatly appreciated.
I ran into the same issue with array-bracket-spacing and was able to fix it by downgrading eslint in my package.json from "^8.6.0" to "^7.32.0". None of the other suggested fixes worked for me either
Upgraded eslint-plugin-vue to 9.1.1
Solved it for me
I have a freshly created project in vue.js, everything worked(homepage). Then I installed bootstrap-vue with these steps.
$ yarn add bootstrap bootstrap-vue.
$ npm install bootstrap bootstrap-vue --save.
But after installing bootstrap I'm getting stuck with this error:
-Error: Cannot find module '#vue/ref-transform'

Bootstrap Vue is not (yet) compatible with Vue 3.
Current plan is:
BootstrapVue v2:
Feature-freeze after v2.17.0
Only critical bugfixes and security updates
BootstrapVue v3:
Based on BootstrapVue 2.17.0
Vue.js v3 support
Bootstrap v4.x support
Release: Short after Vue.js v3 release
BootstrapVue v4:
Complete rewrite
Vue.js v3 support
Bootstrap v5 support
Release: No ETA yet
So yeh, its coming ;)

The template I downloaded is a personal one for a company but here is the package.json to see what it entails
If and not missing something, to make it work follow or check you did the next steps:
Download ESLint and Prettier extensions for VSCode if you didn't
Install ESlint and Prettier libraries in your project npm install -D eslint prettier (or use yarn)
Install eslint-config-prettier (disables formatting for ESLint) and eslint-plugin-prettier (allows ESLint to show formatting errors as we type) npm install -D eslint-config-prettier eslint-plugin-prettier
After that and if all your dependencies are installed taking in consideration your eslintrc file, you should be able to restart vscode and see the errors in the editor directly.
Note that this is something "generic" and you may need to install more packages to add more validations.
