Implementing The Sidecar Pattern in a Microservices Based Application

The Sidecar Pattern is a design pattern that attaches a secondary component to a primary application to handle secondary tasks without changing the application code. It offers benefits such as isolation of responsibilities, ease of maintenance, language-neutrality, and scalability and efficiency. The pattern can be implemented in Node.js using container-based implementation (using Kubernetes or Docker), service mesh implementation (using Istio), or independent components (using Bit).
