1. Install as devDependencies

   npm add --save-dev vite-plugin-ts5-nameof
   # or
   yarn add --dev vite-plugin-ts5-nameof
   # or
   pnpm add --save-dev vite-plugin-ts5-nameof

2. Inject vite-plugin-ts5-nameof using the vite.config.ts module

   import vue from '@vitejs/plugin-vue';
   import { defineConfig } from 'vite';
   import tsNameof from 'vite-plugin-ts5-nameof';
   
   // https://vitejs.dev/config/
   export default defineConfig({
     plugins: [tsNameof(), vue()],
   });

3. Add ts5-nameof.d.ts to your tsconfig.json

   {
     // "compilerOptions"
     // "include"
     // ...
     "files": ["./node_modules/ts5-nameof/ts5-nameof.d.ts"]
   }
