title: In sapper create separate backend API in Polka or Use Same Polka server.js
body: <p>I am new to this. So please help me. I want to ask some questions about the sapper. I have to create separate backend API in Polka (express any framework) or I can use same Polka(express) for backend? Do i have to validate requests through the same polka server? (right now I am using pug template engine with express).</p>
