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: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.

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.

Software failure outside Node.js or hardware failure.The server shuts down either manually or by a scheduled task.An unhandled exception (error) is thrown.
This server will be running for the lifetime of the application, or until: It's a popular choice among developers due to its flexibility, adoption, and trusted ecosystem. What is Express.js?Įxpress.js is a minimal and flexible Node.js web framework. It's designed for the frontend experience build Hybrid frontends with tools like Next.js, develop lightweight event-driven APIs, and deploy to our Global Edge Network. Vercel is a cloud platform to deploy frontend applications. First, let's understand what we are trying to achieve when deploying Express.js apps to Vercel. In this guide, we will cover each step in-depth to deploy an Express.js application to Vercel using Serverless Functions. Express.js is a popular framework used with Node.js.
