TypeScript build errors

Question

I am trying to convert a Vuejs application to incrementally use Typescript and facing several build issues. The application's package.json shows "@vue/cli-plugin-typescript": "^4.3.1", "typescript": "^3.5.2",

I was able to fix a couple of build issues by a. creating .d.ts file eg: I fixed build error related to import VueTour from 'vue-tour'; in main.ts by creating a vue-tour.d.ts file with declare module 'vue-tour';

b. adding // @ts-ignore before the build line error. eg:

// @ts-ignore
import axios from "./axios.js";

~\src\axios.js

import axios from 'axios'
const domain = ""
export default axios.create({domain})

Instead of using // @ts-ignore, how can I create a .d.ts file to fix the build issue?

I also have build errors related to types generated by AWS Amplify and a custom router instance that we use.

What is the recommended way to solve these build issues?

~\src\router.js

import Vue from 'vue';
import Router from 'vue-router';
Vue.use(Router);
const router = new Router({............
});
export default router;

Answer 1

I added the "skipLibCheck": true to the tsconfig.json file to fix build issue 2. This should be ok as we do not want to check DocumentNode for lib dependencies.
