Main Concepts of Microservices in Node.js

• Microservices vs. Monoliths:

  • Understand the difference between microservices and monoliths in software architecture. Microservices are smaller, decoupled services that work together, while monoliths are large, single units of code.

• Architecture Patterns in Microservices:

  • Learn about different architecture patterns such as event-driven, API gateway, CQRS, and event sourcing. Each pattern serves a specific purpose in designing microservices.

• Containerization with Docker:

  • Explore how to create a containerized environment for local development using Docker and Docker Compose. Containers help streamline the deployment process.

• Node.js Microservices:

  • Dive into building Node.js microservices using Express and Nest JS. Learn how to create simple microservices, expose REST APIs, and implement best practices for scalable architecture.

• Event-Driven Architecture:

  • Understand how microservices can implement event-driven architecture with messaging queues like RabbitMQ. Event-driven systems react to events in the system, enabling real-time communication.

• GraphQL Interface:

  • Explore building microservices with a GraphQL interface, in addition to REST APIs. GraphQL allows for more flexibility in querying data from your services.

• gRPC and tRPC Interfaces:

  • Learn how to expose microservices with gRPC and tRPC interfaces, enabling efficient communication between services. These interfaces offer different protocols for data transmission.

• Message-Driven Microservices:

  • Discover the concept of message-driven microservices that listen to events from messaging platforms like Kafka or RabbitMQ. These services react asynchronously to messages received.

• 12 Factor Principles:

  • Understand the principles of building robust microservices, including testing, linting, environment separation, and deployment practices. Compliance with these principles ensures a scalable and maintainable architecture.

• Microservice Decoupling:

  • Explore the idea of decoupling microservices from the rest of the architecture, avoiding shared databases and dependencies. Each microservice operates independently, enhancing scalability and reliability.

• Apollo Federation:

  • Learn about Apollo Federation as a tool for composing multiple GraphQL services into a unified graph. This allows for a cohesive and efficient GraphQL API design.

By grasping these main concepts in microservices, you can gain a comprehensive understanding of building scalable, efficient, and decoupled software systems using Node.js.
