For my specific condition I don't want to generate hash in file name for some specific files. I tried something like this, but its removing hash from .css files but not for the .js files.

  build: {
    target: 'es2020',
    rollupOptions: {
      input: {
        main: fileURLToPath(new URL('./index.html', import.meta.url)),
        myapp: fileURLToPath(new URL('./src/my-app.ts', import.meta.url))
      },
      output: {
        assetFileNames: (assetInfo) => {
          if (assetInfo.name?.toLocaleLowerCase().includes('myapp')) {
            return 'assets/[name][extname]';            
          }
          return 'assets/[name]-[hash][extname]';
        },
      },
