Setting up Meteor, Vue and Typescript

Question

I'm struggling to get Meteor, Vue and Typescript to work together. I can't find any tutorials on Meteor, Vue and Typescript and the example github projects don't work correctly either and use workarounds to avoid the issues I'm having. E.g. Separating the Typescript code into its own file instead of having it within the script tag.

According to this tutorial I should be able to define my component in two different ways.

1

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

@Component
export default class HelloWorld extends Vue {
}
</script>

2

<script lang="ts">
@component({
    name: 'HelloWorld'
})
</script>

If I create a meteor vue project and do these steps, the code above has errors.

Meteor Create

meteor create --vue "vue-typescript-test"

Add tsconfig.json

{
  "compilerOptions": {
    "lib": ["dom", "es5", "es2015"],
    "target": "es5",
    "module": "es2015",
    "moduleResolution": "node",
    "sourceMap": true,
    "allowSyntheticDefaultImports": true
  }
}

Add ts-loader

npm i -D typescript ts-loader

Add vue-property-decorator

npm install vue-property-decorator

If I change the script in Hello.vue to use Typescript like the tutorials mention, I get an error.

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

@Component({
  name: 'Hello'
})
</script>

Error

How should a Meteor, Vue and Typescript project be set up correctly?

Update

If anybody can show steps for how to create a Meteor, Vue, Typescript and Vue Class Component syntax project that would solve my problem.

Answer 1

You need to provide a repository for us to help you. By the way your tutorial is not a tutorial to follow step by step. It just explain how things work. I'd recommend you to find another.

I don't know what is your point but if it's just to have an VueJS with Meteor (using typescript) I'd recommend you to refer to the documentation of the official framework. I can guarantee you it is better than a tutorial.

Here is for vueJS https://guide.meteor.com/vue.html

And here is for the typescript part https://guide.meteor.com/build-tool.html#typescript

In case you don't want to follow the documentation for any reason and stay with your projet, so we'll have to read what it says.

Can't find handler for lang 'ts'

ts-loader is package that will let you use lang="ts" in your script.

I guess you have the message above because it is not configured. So you'll have to find how to configure it.

In https://cnpmjs.org/package/ts-loader it says :

Configuration Create or update webpack.config.js like so:

module.exports = {
  mode: "development",
  devtool: "inline-source-map",
  entry: "./app.ts",
  output: {
    filename: "bundle.js"
  },
  resolve: {
    // Add `.ts` and `.tsx` as a resolvable extension.
    extensions: [".ts", ".tsx", ".js"]
  },
  module: {
    rules: [
      // all files with a `.ts` or `.tsx` extension will be handled by `ts-loader`
      { test: /\.tsx?$/, loader: "ts-loader" }
    ]
  }
};

Add a tsconfig.json file. (The one below is super simple; but you can tweak this to your hearts desire)

{
  "compilerOptions": {
    "sourceMap": true
  }
}
