Typescript example runs with errors

Version

v2.4.5

Reproduction link

https://github.com/nuxt/nuxt.js/tree/dev/examples/typescript

Steps to reproduce

Run the app (npm run dev)

What is expected ?

“Hello from client !” should be posted in the dev console, and the app should run without issues. (I had to change the file to .js because server is not defined on the process object.

What is actually happening?

One error and 2 warnings are displayed in the console (although the site displays correctly).

ReferenceError: [nuxt] Error while mounting app: exports is not defined at Module../node_modules/babel-loader/lib/index.js?!./node_modules/ts-loader/index.js?!./node_modules/vue-loader/lib/index.js?!./pages/index.vue?vue&type=script&lang=ts& (index.js:220)

@MrJmpl3 will be fixed in 2.6, Nuxt won’t override your tsconfig.json anymore.

Version: 2.5.1 , Nuxtjs add "strict": true in my custom tsconfig.json in npm run dev
