What are Next.js Functions? Why are they important?#

Today, the Vercel team announced the Next.js Edge functions. Edge functions allow developers to run their code at the servers distributed globally. This means your code will be executed at the location that is closest to your user. You can think of edge functions as the serverless functions which are run at the CDN infrastructure. Edge functions have the following advantages:

  • Global low latency: Because the code is replicated to many global locations (PoP: points of presence), a user anywhere in the world will experience low latency. Each client will fetch the response from the nearest server.
  • No cold start: Edge infrastructure providers use V8 Isolates which eliminates the cold starts. This means much faster startups.

In this article, we will build a Serverless Next.js based TODO application. We will try our best to make it minimalist. It will not have any database connection. It will not have any extra dependency other than Next.js. It will not have any buttons. Besides, minimalism is cool and clean, I love it because I am a lazy developer :)

Why do we avoid database connections?#

Next.js is a modern framework which enables the front-end developers to develop full stack applications. Serverless functions have an important role in simplifying backend development for Next.js developers. As you probably know, serverless functions do not like database connections due to their stateless nature. See here and here as examples of problems of database connections inside serverless functions.
