Starting a serverless JS project with GitLab

Serverless Function as a Service (FaaS) solutions, such as AWS Lambda and Knative, allow developers to write discrete functions triggered by events, abstracting away server management and often resulting in significant cost savings due to on-demand resource provisioning. As these solutions gain popularity, tools have emerged to simplify their use, including a GitLab project template that facilitates the deployment of serverless applications without command-line interaction. To illustrate the process, a step-by-step guide details setting up a project using the GitLab serverless template, configuring AWS credentials, and deploying an AWS Lambda function. The guide also demonstrates creating a simple calculator function using the Serverless Framework, showcasing how changes can be made and deployed seamlessly through GitLab's CI/CD pipeline, culminating in an accessible web page where the function can be tested. This approach provides a user-friendly introduction to serverless computing, encouraging experimentation and further exploration.
