If you’re looking to dive deep into the world of microservices, ‘NestJS Microservices: Build a Distributed Job Engine’ on Udemy is a course that is hard to miss.
**Course Overview**
This course takes you on a comprehensive journey, starting from the fundamentals of NestJS microservices to deploying a fully functional job engine. The instructor does a fantastic job of breaking down complex concepts into digestible segments. You will learn to set up a monorepo with Nx, which is essential for managing multiple microservices efficiently.
One of the highlights of this course is its focus on using gRPC as a transport layer. This choice enables high-performance and low-latency communication between services, which is crucial for any distributed system. The course also introduces you to Apache Pulsar, a powerful distributed messaging system that enhances the scalability of your application by allowing multiple consumers to handle a shared queue.
**Hands-On Learning**
What I appreciate most about this course is its practical approach. You won’t just learn theory; you will build a job engine from the ground up. This hands-on experience is invaluable, particularly for those who prefer learning by doing. The course also covers GraphQL APIs, which provide a flexible and efficient way for microservices to communicate with one another.
**Security and Best Practices**
Security is a core focus throughout the course. You will implement JWT-based authentication, which is vital for protecting your services. Learning to secure your application using HTTP-only cookies is another crucial lesson that this course provides. Additionally, the object-oriented design principles emphasized in the course contribute to a clean, modular, and maintainable codebase that adheres to the DRY (Don’t Repeat Yourself) principle.
**Advanced Topics**
As you progress, you will also learn how to optimize your Docker setup using Nx libraries and separate package.json files for better dependency management. The course covers horizontal scaling techniques, ensuring your services can efficiently handle increased workloads. You will also implement job state tracking, allowing you to monitor job progress, which is a key feature for any job engine.
**Database Management**
For database management, the course utilizes Prisma ORM and Drizzle ORM with PostgreSQL. This ensures type safety, migrations, and optimized queries, making your application robust and reliable.
**Deployment**
Finally, you will deploy your entire setup to Kubernetes, taking your microservices to production with AWS, a custom domain, and SSL encryption. This final step is where your hard work pays off, as you see your job engine come to life in a production environment.
**Conclusion**
By the end of this course, you will not only have a fully operational distributed job engine but also the expertise to design, develop, and deploy scalable NestJS microservices in real-world scenarios. I highly recommend this course to anyone looking to sharpen their skills in microservices architecture and development. Whether you are a beginner or have some experience, this course will elevate your understanding of NestJS and microservices to the next level.
