Can't use '@' for addressing assets in vuejs(ts) templates and in scss files

[SeyyedKhandon]

Please consider below sample code which is a simple vue.js(ts) SFC (Loading.vue):
(the reprex link is at the bottom of this question)

<template>
  <div class="loading_container">
    <img
      class="loading_logo"
      src="@/assets/images/logo.png"
      alt="company logo"
    />
    <div class="loading_box">
      <div class="loading_dot"></div>
      <div class="loading_dot"></div>
      <div class="loading_dot"></div>
      <div class="loading_dot"></div>
    </div>
  </div>
</template>

<script lang="ts">
import { defineComponent } from "@vue/composition-api";
export default defineComponent({
  name: "Loading"
});
</script>

and the corresponding story:

import Loading from "../src/views/components/loading/Loading";
import  "../src/assets/styles/index.scss";
// import  "../src/assets/styles/components/_Loading.scss";
export default {
  title: "Loading"
};

export const normalLoading = () => ({
  components: { Loading },
  template: "<Loading></Loading>",
});

this is my ./storybook/webpack.config.js to support scss files.

const path = require("path");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

module.exports = function({ config }) {
  config.module.rules.push({
    test: /\.scss$/,
    loaders: [MiniCssExtractPlugin.loader, "css-loader", "sass-loader"],
    include: path.resolve(__dirname, "../")
  });
  config.plugins.push(new MiniCssExtractPlugin({ filename: "[name].css" }));

  return config;
};

and tsconfig if it is needed for you, beacuse it has a path as source(i think it might be related, but not sure, because it should work on ts files, by the way i put it here):

{
  "compilerOptions": {
    "target": "esnext",
    "module": "esnext",
    "strict": true,
    "jsx": "preserve",
    "importHelpers": true,
    "moduleResolution": "node",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "resolveJsonModule": true,
    "sourceMap": true,
    "baseUrl": ".",
    "types": [
      "webpack-env",
      "jest"
    ],
    "paths": {
      "@/*": [
        "src/*"
      ]
    },
    "lib": [
      "esnext",
      "dom",
      "dom.iterable",
      "scripthost"
    ]
  },
  "include": [
    "src/**/*.ts",
    "src/**/*.tsx",
    "src/**/*.vue",
    "tests/**/*.ts",
    "tests/**/*.tsx"
  ],
  "exclude": [
    "node_modules"
  ]
}

when I run npm run storybook, it keeps showing errors which cant resolve logo.png and other SVG assets which is been addressed in the scss files like "./assets/images/alert-triangle.svg".

here is the error log:

reprex

here is the reprex,(i commented the ./storybook/webpack.config.js):

https://github.com/SeyyedKhandon/vuejs-persian-chat-scaffold/tree/storybook

[SeyyedKhandon]

@yyx990803 , @shilman
I'm thinking about using vue-cli's webpack config for using storybook with vuejs, is it a proper solution?

[backbone87]

Do you use vue-cli-plugin-storybook?

[SeyyedKhandon]

@backbone87 I've used https://storybook.js.org/docs/guides/guide-vue/ automatic install which tells npx -p @storybook/cli sb init --type vue to install storybook. how should I use vue add vue-cli-plugin-storybook instead of that?

package.json:

  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "test:unit": "vue-cli-service test:unit",
    "lint": "vue-cli-service lint",
    "storybook": "start-storybook",
    "build-storybook": "build-storybook"
  },

[SeyyedKhandon]

Thank you @backbone87 , @shilman , everything is working now.

First, I stashed all changes which have been made by following the instructions of
https://storybook.js.org/docs/guides/guide-vue/ .

Then I've re-installed storybook via using vue add storybook ( https://github.com/storybookjs/vue-cli-plugin-storybook ) which creates a folder that contains webpack configs from vue-cli, which means you don't need to have any special webpack section in storybook config folder. the @ problem has been solved and every thing is fine

<img
  class="loading_logo"
  src="@/assets/images/logo.png"
  alt="company logo"
/>

But still there was one error for addressing assets in .scss url() like content:

url("assets/images/tick.svg"); 

I fixed it by using relative addressing using ~@ together like below:

content: url("~@/assets/images/tick.svg");

the working example is here:
