  1. Install the Vite initialization project
npm init vite-app vue3-pro

Integrated typescript

  1. Install and initializetypescript.npm 5.xLater versions provide an NPX command that directly executes the executable in the node_modules/.bin/ directory, so we can use it to use the TSC command
npm install typescript -D
npx tsc --init
Copy the code

2. Configuration tsconfig. Json
