preload option : how i can use ?

[RichySano]

Hi,

In documentation of electron-vite , i can use

export default defineConfig({
preload: {
build: {
rollupOptions: {
output: {
format: 'es'
}
}
}
}
// ...
})

In discussion section of electron-vite (sandbox: true? #423), we can see :

preload: {
build: {
rollupOptions: {
output: {
format: 'cjs',
},
},
},
},

How i can use it nuxt-electron ?

electron: {     
        {                
            entry: 'electron/preload.ts',
            vite: {                    
                build: {
                    rollupOptions: {
                        output: {
                            format: 'cjs'
                        },
                    },
                },
            },                
            onstart(args) {
                args.reload();
            },
        },
    ],        
    renderer: {},
    disableDefaultOptions: false,
},

because cjs file is not generated.

Please help me

                      }
                    }
