What should I put in 'platform' when connecting to storefront_api?

[shunnokw]

I already setup spree2vuestorefront and have a single end point at port 8889
I also setup my elastic search instance and imported everything
What platform should I use at local.config file?
And what should I put in index.js?

 let modules = [
    DefaultVuestorefrontApiModule({
        platform: {
            name: 'magento2',
            platformImplementation: magento2
        }
    }),
    DefaultCatalogModule(),
    DefaultImgModule(),
]

Also, where should I put the endpoint url in?

Thank you
