DevTools in vue.js - vuejs2

I am using vue.js inside Laravel 5.5.33 (not SPA). I am getting below error.
How can I enable DevTools?

Be sure you have this setting in your app.js file
Vue.config.devtools = true
If you are using mix, check the dist of vue in webpack.mix, be sure you don't use min version
mix.js('resources/js/app.js', 'public/js')
.sass('resources/sass/app.scss', 'public/css')
.webpackConfig({
resolve: {
alias: {
'vue$': 'vue/dist/vue.js'
}
}
});
Run your npm in dev
npm run watch
WARNING
If you refresh your page in your browser, the cache is not refreshed. Clean the cache to reload the app.js

This is an old issue when production grade build is used.
You are probably using Vue from CDN, and probably using a production build (dist/vue.min.js). Either replace it with a dev build (dist/vue.js) or add Vue.config.devtools = true to the main js file.
Check out the github link.

But, for me, the problem with DevTools was solved just when I put the line that is provided in the answer below after creating your Vue application.
Your code should look like this
new Vue({
el: '#app',
data () {
text: 'testData'
}
})
Vue.config.devtools = true

How to prerender a Vue3 application?

I try without success to apply a prerendering (or a SSG) to my Vue3 application to make it more SEO friendly.
I found the vue-cli-plugin-prerender-spa, and when I try it with the command line: vue add prerender-spa I have the error:
ERROR TypeError: Cannot read properties of undefined (reading 'endsWith')
After that I tried prerender-spa-plugin but I have an error when I make a npm run build:
[prerender-spa-plugin] Unable to prerender all routes!
ERROR Error: Build failed with errors.
Error: Build failed with errors.

What do you think about this? Do you have any idea?
Nuxt3 is a really powerful meta-framework with a lot of features and huge ecosystem. Meanwhile, it's in RC2 right now so not 100% stable (may still work perfectly fine).
If your project is aiming for something simpler, I'd recommend using Vitesse. It may be a bit more stable and it's probably powerful enough (check what's coming with it to help you decide).
Some solutions like Prerender also exist but it's paid and not as good as some real SSG (/SSR). Also, it's more of a freemium.
I struggled with the same error output until I found the prerender-spa-plugin-next. Then I notice the latest version of prerender-spa-plugin was published 4 years ago and prerender-spa-plugin-next is continually updating. It seems like that prerender-spa-plugin-next is a new version of prerender-spa-plugin with the same functions. So I use prerender-spa-plugin-next instead of prerender-spa-plugin then everything works fine!
Here is my step:
install the package
npm i -D prerender-spa-plugin-next
modify vue.config.js like
const plugins = [];
if (process.env.NODE_ENV === 'production') {
const { join } = require('path');
const PrerenderPlugin = require('prerender-spa-plugin-next');
plugins.unshift(
new PrerenderPlugin({
staticDir: join(__dirname, 'dist'),
routes: ['/'], //the page route you want to prerender
})
);
}
module.exports = {
transpileDependencies: true,
configureWebpack(config) {
config.plugins = [...config.plugins, ...plugins];
},
};
build
npm run build
Then check the index.html under the dist folder you can see the page is prerendered.
Further usage refers to the homepage of prerender-spa-plugin-next
Found and fix about the scss files to import.
In nuxt.config.ts use :
vite: {
css: {
preprocessorOptions: {
scss: {
additionalData: `
#import "#/assets/scss/_variables.scss";
#import "#/assets/scss/my-style.scss";
`
}
},
},
}
Now my 2 mains issue are : how to install vuetify properly, currently syles and components seems working but the JS not, for example, accordions don't expands on click.
And second topic is to have a i18n module, it seems that vue-i18N no longer works.
Thanks.

solved: Remove Webpack debugging from production for VueJs project

I created new fresh project with latest VueJS-cli tool. Looks like VueJS CLI is using Webpack 4.43.0.
How to remove that Webpack section, that is visible under browser console/debugging tab?
All code with comments are visible and nothing is striped and uglified.
yarn build shows that it is building for production. Also I tried export NODE_ENV=production
Thanks in advance
I solved.
In : vue.config.js
module.exports = {
configureWebpack: {
devtool: false
}
}

Configuring Vue and Webpack in Vuepress app

In my Vuepress project I would like to use v-runtime-template.
Their setup instruction says
You must use the with-compiler Vue.js version. This is needed in order to compile on-the-fly Vue.js templates. For that, you can set a webpack alias for vue to the vue/dist/vue.common file.
This could be achieved by adding
module.exports = {
runtimeCompiler: true
};
to vue.config.js, but I do not understand how to configure in Vuepress.
I tried this:
// .vuepress/enhanceApp.js
export default ({ Vue, options, router, siteData }) => {
Vue.config.runtimeCompiler = true
}
but it did not give any results.
How should the configuration be done?
From: https://github.com/vuejs/vuepress/issues/402#issuecomment-388169056
Add the following to your .vuepress/config.js:
chainWebpack(config) {
config.resolve.alias.set('vue', 'vue/dist/vue.common.js')
}

Vue3 autoprefixer config issue

I have a new project that was created with Vue-cli 3 using vue create my-new-project. I am using CSS grid for some layout things and i need to support IE11 and newer. Vue docs say that autoprefixer is loaded and enabled by default but its not working. I cant get it to work in either npm run build or npm run serve. Works fine in chrome but IE11 its not working. Im sure there is some config that needs to be done but im unsure what that may be.
.browserslistrc:
> 1%
last 4 versions
postcss.config.js:
module.exports = {
plugins: {
autoprefixer: {}
}
};
CSS Grid support is disable by default.
You can enable it by using either the grid: autoplace option or the /* autoprefixer grid: autoplace */ control comment.
module.exports = {
plugins: {
'autoprefixer': {
grid: 'autoplace'
},
}
};
Does Autoprefixer polyfill Grid Layout for IE?

How to disable source map or debug mode in production Vue.js - Webpack

I am working on a Vue.js project and all files are generated by webpack on dev and production mode.
but here is my problem :
I can see my vue components in devtools when I inspect on a element.
How could I disable that ?
By the way source map is disabled and I have no .map files in dist folder.
thank you :)
Just checkout the Vue cli docs:
productionSourceMap Type: boolean
Default: true
Setting this to false can speed up production builds if you don't need
source maps for production.
So in your webpack config you write:
module.exports = {
productionSourceMap: false
};
If your vue.config.js which is responsible for your webpack configuration doesn't exist, you may create it.
If webpack has been configured from scratch, it can be removed by deleting or commenting in any case in the webpack production file
the devtool option
tools/webpack.prod.js
module.exports = merge(common, {
// devtool: "source-map",
mode: "production",
...
});
