Steps to reproduce

vue create vue-test

• select Manually select features
• select TypeScript and Router
• continue with default settings

in vue-test
npm run serve

What is expected?

App.vue should contain with <router-link> and <router-view>
to switching Home and About pages.

Web UI should contain a header with Home and About tab

What is actually happening?

App.vue only contains HelloWorld component, ./views/Home.vue and ./views/About.vue would not to be used.

Web UI shows HelloWorld without header.
