Rollup-Plugin-Ts-Vue

Note: Version 0.6.0 covers updated NPM packages due to Github's security advisory. !! Use at your own risk !!

Plugin for Rollup to bundle Vue components written in TypeScript.

This plugin was in inspired by rollup-plugin-typescript, which uses Typescript's API. Added support for SCSS and Vue.

Feel free to use my full boilerplate project here on Github.

Why

Why another plugin?? I love writing in Typescript and love the Vue single component concept. However, the similar plugins rely on other tools to complete the job. Wanted a way to reduce over-head of other tool-sets like; Babel, Webpack, etc. and replace with a simpler tool.

NOTE: currently scoped styles are partially supported and in-beta. Work-in-Progress

Rollup Config

import resolve from "./node_modules/@rollup/plugin-node-resolve/dist/index.es";
import vue from "./node_modules/rollup-plugin-ts-vue/dist/rollup-plugin-ts-vue.es";

export default {
    input: "./src/main.ts",
    output: {
        name: "app",
        format: "iife",
        file: "./dist/js/app.js",
        globals: {
            "vue": "Vue",
            "vue-router": "VueRouter",
            "vuex": "Vuex",
            "vue-property-decorator": "VueClassComponent",
            "vue-class-component": "VueClassComponent"
            "axios": "axios"
        },
        sourcemap: true,
        sourcemapFile: "./dist/js/app.js.map"
    },
    plugins: [
        resolve(),
        // null == defaults to tsconfig.json
        vue(null, {
            output: "./dist/css/site.css",
            includePaths: ["src/scss"]
        })
    ],
    external: [
        "vue",
        "vue-router",
        "vuex",
        "vue-class-component",
        "axios"

Examples of Strong-Typed Vue Components

Standard Vue Mixin Object

<template>
  <div>{{msg}}</div>
</template>

<script lang="ts">
  import Vue, { ComponentOptions } from "vue";

  export default {
    data() {
      return {
        msg: "Hello World",
      };
    },
  } as ComponentOptions<any>;
</script>

<style lang="scss"></style>

Vue Extend

<template>
  <div>{{msg}}</div>
</template>

<script lang="ts">
  import Vue from "vue";

  export default Vue.extend({
    data() {
      return {
        msg: "Hello World",
      };
    },
    created() {
      let vm = this as VueComp;
      vm.msg = "Hello World Too!!";
    },
  });

  interface VueComp extends Vue {
    msg: string;
  }
</script>

<style lang="scss">
  $myColor = blue;

  div {
      color: $myColor;
  }
</style>

vue-property-decorator

<template>
  <div>{{msg}}</div>
</template>

<script lang="ts">
  import { Component, Vue } from "vue-property-decorator";

  @Component({
      name: "component-template"
  })
  export default class ComponentTemplate extends Vue {
      msg: string = "Hello World";

      created() {
          this.msg = "Hello World Too!!";
          console.log(Created: life-cycle hook);
      }
  }
</script>

<style lang="scss">
  div {
    color: blue;

    a {
      color: green;
    }
  }
</style>

Typescript Path Translation

When using paths in tsconfig, rollup doesn't understand how to translate so it may resolve the module. When using something like this; import MyMod from "@/components/my-module". Rollup will assuming its an external dependencies. This plugin will attempt to resolve and correct the module path before passing to Rollup.

tsconfig.json

{
    ...

    "baseUrl": ".",
    "paths": {
      "@/*": [ "src/*" ]
    }

    ...
}

Change Log

• 0.1.0 inital release
• 0.2.0 fix nested template tags being removed.
• 0.3.0 scoped CSS (beta) and Typescript Path Translation.
• 0.4.0 include sass compiler into project vs using another plugin. Also switch from node-sass to sass due to tar@2.0 errors.
• 0.5.0 While working with CI/CD in Azure, Rollup failed to create the missing directory from the plugin's CSS output path:
  • vue(null, { output: "./dist/css/site.css", includePaths: ["src/scss"] })
• 0.6.0 Updated the NPM packages to the latest due to Github's security advisory.
  • I would assume this project has been deprecated with the release of Vue 3 and Vite.
  • This project gets 29 downloads per week. I didn't test it. !! Use at your own risk !!
