Vanilla install will not build

[Chris]

A complete new app with typescript fails to build with error:

ERROR in ../src/router/index.ts(25,11):
TS2591: Cannot find name 'process'. Do you need to install type definitions for node? Try npm i @types/node and then add node to the types field in your tsconfig.

Using yarn: 1.21.1
node: v10.17.0
quasar: 1.4.3
@quasar/quasar-app-extension-typescript: ^1.0.0-beta.2

I created a fresh app with 'quasar create', accepted the default prompts and added ESLint, Vuex, Axios, IE11.

cd into the project directory and run quasar ext add @quasar/typescript and press enter to accept all the defaults.

Run 'quasar b' and the build fails.

If I create an app without the 'experimental' convert .js to .ts files then the app builds ok.

Output from 'quasar info':
Operating System - Linux(3.10.0-1062.9.1.el7.x86_64) - linux/x64

I managed to fix this by adding 'node' to the types array in the tsconfig. The extension is installing the @types/node package but doesn't appear to add it to the tsconfig.

"types": [ "quasar", "node" ]

[Paolo Caleffi]

It shouldn't need to do so, given how TS types resolution works

Please try with the new starter kit TypeScript option or with TS config preset
