Serverless Functions and Databases

During application development, it is often required to connect to a database for data access. Since, using the Jamstack, we no longer have access to an origin server, we need to look for other ways to execute database queries.

One such way is to leverage serverless functions. And herein lies the problem. Often there's a misconception when it comes to these functions and how database connections should be managed.

In this short course, we focus on demystifying the misconceptions based around the need to create persistent database connections. Furthermore, we also examine another crucial aspect of working with serverless functions: managing payloads sent via the HTTP POST method.

The course will walk you through a sample app (created using Vue.js) where you get the opportunity to learn via hands-on examples how serverless functions can manage connections to a MongoDB Atlas cluster, how they can handle query parameters and POST payloads using the platform provided by Vercel.
