Drawbacks and Edge Cases Templating and View Engines We recommend using this approach instead of express.static. Serving static files with Vercel allows us to do static asset hoisting and push to our Global Edge Network. Instead, we can add a /public folder to the root. To serve static content, we would normally do app.use(express.static('public')) in our main file app.js. ![]() For example, the following API route pages/api/user.js handles a json response: export default function handler ( req, res ) Īdding rewrites to vercel.json. We recommend using API Routes with Next.js to create Serverless Functions.Īny file inside the folder pages/api is mapped to /api/* and will be treated as an API endpoint instead of a page. This is an anti-pattern, as Serverless Functions should serve one purpose. #FREE PROGRAM ALTERNATIVE TO EXPRESS FILES FULL#When we deploy a server (Express.js based application) within a Serverless Function, we are executing a full server implementation on each request. Developers focus on business logic – functions that return value. Plus, there is no overhead managing and maintaining servers. It's fully automated and can scale up in milliseconds. Pieces of backend code run in stateless compute environments that are triggered by events (like requests) and may last for one invocation. The serverless approach is quite different. As you can imagine, this is difficult to implement correctly. As you scale your application, you'll need to consider: cost, flexibility, security, rapid provisioning, and much more. Traditional APIs are hosted using a running server. #FREE PROGRAM ALTERNATIVE TO EXPRESS FILES SOFTWARE#
