Answer 1

FYI, you can generate . d.ts file for your components by turn on declaration generate in tsconfig. json, copy them to the source dir, see what you've got!

Answer 2

From Alex Jover:

If your editor is yelling at the line import App from './App' in main.js file about not finding the App module, you can add a vue-shim.d.ts file to your project with the following content:

declare module "*.vue" {
  import Vue from 'vue'
  export default Vue
}

and write :

import App from './App.vue'

instead of

import App from './App'

Answer 3

When using the vue-cli, adapt vue-loader-conf.js as follows:

var utils = require('./utils')
var config = require('../config')
var isProduction = process.env.NODE_ENV === 'production'

module.exports = {
  loaders: utils.cssLoaders({

    sourceMap: isProduction
      ? config.build.productionSourceMap
      : config.dev.cssSourceMap,
    extract: isProduction, esModule: true
  }), esModule: true
}

Answer 4

Check out vue-class-component. Basically, you must add appendTsSuffixTo: [/\.vue$/] to ts-loader's options and esModule: true to vue-loader's options.

// webpack.config.js

{ modules: { rules: [
  {
    test: /\.ts$/,
    exclude: /node_modules|vue\/src/,
    loader: "ts-loader",
    options: { appendTsSuffixTo: [/\.vue$/] }
  },
  {
    test: /\.vue$/,
    loader: 'vue-loader',
    options: {
      esModule: true
    }
  }
]}}

I may have missed something else.
