cd tauri-app
npm install
mkdir sidecar
cd sidecar
npm init
npm add @yao-pkg/pkg --save-dev
add the index.js code as stated
npm run pkg -- --output app
Observe error
I needed to add my own build script which isn't mentioned anywhere
"build": "tsc index.ts && pnpm exec pkg index.js --output app && node move.js"
And manually create the src-tauri binaries directory for the given rename script to work.
After that it still doesn't work.
import { Command } from '@tauri-apps/plugin-shell';
