webpack config missing in vuejs

Question

My vuejs app's package.json looks like

package.json

{
  "name": "vue_app",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve --open",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "axios": "^0.18.0",
    "vue": "^2.5.13",
    "vue-router": "^3.0.1",
    "vuex": "^3.0.1"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "^3.0.0-beta.6",
    "@vue/cli-plugin-eslint": "^3.0.0-beta.6",
    "@vue/cli-service": "^3.0.0-beta.6",
    "@vue/eslint-config-standard": "^3.0.0-beta.6",
    "lint-staged": "^6.0.0",
    "node-sass": "^4.7.2",
    "sass-loader": "^6.0.6",
    "vue-template-compiler": "^2.5.13"
  },
  "babel": {
    "presets": [
      "@vue/app"
    ]
  },
  "eslintConfig": {
    "root": true,
    "extends": [
      "plugin:vue/essential",
      "@vue/standard"
    ]
  },
  "postcss": {
    "plugins": {
      "autoprefixer": {}
    }
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not ie <= 8"
  ],
  "gitHooks": {
    "pre-commit": "lint-staged"
  },
  "lint-staged": {
    "*.js": [
      "vue-cli-service lint",
      "git add"
    ],
    "*.vue": [
      "vue-cli-service lint",
      "git add"
    ]
  }
}

Upon building the vue app, it generates an index.html file while looks like,

dist/index.html

<body>
    <noscript><strong>We're sorry but vue_app doesn't work properly without JavaScript enabled. Please enable it to continue.</strong></noscript>
    <div
        id=app></div>
        <script type=text/javascript>
            (function(r){var n=window["webpackJsonp"];window["webpackJsonp"]=function(e,u,c){for(var i,f,p,l=0,a=[];l<e.length;l++)f=e[l],t[f]&&a.push(t[f][0]),t[f]=0;for(i in u)Object.prototype.hasOwnProperty.call(u,i)&&(r[i]=u[i]);n&&n(e,u,c);while(a.length)a.shift()();if(c)for(l=0;l<c.length;l++)p=o(o.s=c[l]);return p};var e={},t={2:0};function o(n){if(e[n])return e[n].exports;var t=e[n]={i:n,l:!1,exports:{}};return r[n].call(t.exports,t,t.exports,o),t.l=!0,t.exports}o.m=r,o.c=e,o.d=function(r,n,e){o.o(r,n)||Object.defineProperty(r,n,{configurable:!1,enumerable:!0,get:e})},o.n=function(r){var n=r&&r.__esModule?function(){return r["default"]}:function(){return r};return o.d(n,"a",n),n},o.o=function(r,n){return Object.prototype.hasOwnProperty.call(r,n)},o.p="/",o.oe=function(r){throw console.error(r),r}})([]);
//# sourceMappingURL=/js/manifest.bb41d6d8.js.map
        </script>
        <script type=text/javascript src=/js/vendor.be88a6a7.js></script>
        <script type=text/javascript src=/js/app.5edcb6c7.js></script>
</body>

index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <link rel="icon" href="<%= webpackConfig.output.publicPath %>favicon.ico">
    <title>Flask + Vue.js Template</title>
  </head>
  <body>
    <noscript>
      <strong>We're sorry but vue_app doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
    </noscript>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

On running static files are failed to get fetched , ie. /js/vendor.be88a6a7.js returns 404 but it can be fetched by calling /static/js/vendor.be88a6a7.js url. So I have to prepend /static to all the static url paths. But I don't find any webpack.conf file located on that directory.

In vue cli 3 the webpack config file is generated dynamically at runtime. It has been abstracted away. That is the reason you don't see a webpack config file.

You can find the webpack config file here:

<projectRoot>/node_modules/@vue/cli-service/webpack.config.js

This is the file that is dynamically resolved.

The output.publiPath is / by default in the webpack config file. If you want to check want is webpack config file looks like you can use vue inspect command in your command line or via vue ui -> click Tasks -> click inspect. It prints out a serialized format only meant for inspection of the config file.

But if you want to configure the webpack config you can make use of the vue.config.js file.

If you do not have vue.config.js file, then create it in root of your project.

Then add the following:

// vue.config.js
module.exports = {
    configureWebpack: {
        output: {
            publicPath: '/static/'
        }
    }
}

Just wanted to let you know "Configuring Webpack" link is dead.
