Learn how to build API Gateway in NestJs

Requirements
Basic Knowledge of jаvascript/TypeScript – Some experience with jаvascript or TypeScript will help you follow along easily.
Familiarity with Node.js – Understanding of Node.js fundamentals is recommended but not mandatory
Basic Understanding of Databases – Some experience with MongoDB or PostgreSQL will be helpful, but all concepts will be explained.
Willingness to Learn – No prior microservices experience is required! This course is designed to take you from beginner to advanced in NestJS microservices.

Description
NestJS is one of the best frameworks for modern backend development. It combines the best features of Angular, Express, and TypeScript, making it a go-to choice for building scalable, maintainable, and production-ready applications.Are you struggling to build scalable, production-ready microservices with NestJS? Do you want to master RabbitMQ, MongoDB, Postgres Docker, Prisma, and API Gateways while learning real-world best practices? This course is for you!In this comprehensive NestJS Microservices course, you'll learn to build a fully functional microservices architecture from scratch. You'll master inter-service communication, authentication, database integrations, and deployment – all with hands-on projects and practical coding exercises.What You'll Learn:Setup a Scalable NestJS Microservices Project from scratchImplement TCP, RabbitMQ, and API Gateway-based communicationSecure microservices with JWT authentication and NestJS GuardsWork with MongoDB, PostgreSQL, Prisma, and TypeORMContainerize microservices with Docker & Docker ComposeWhy Take This Course? Hands-on projects – Code alongside real-world applications Step-by-step explanations – No prior microservices experience needeUpdated for 2024 – Covers the latest NestJS & microservices patternsIf you're ready to master NestJS Microservices and become a job-ready backend developer, enroll now and start coding! NestJS microservices offer several benefits, especially for building scalable and maintainable backend applications. 1. ScalabilityMicroservices allow independent scaling of different services based on demand.NestJS supports distributed systems, enabling horizontal scaling.2. Decoupled ArchitectureEach microservice is independent, making it easier to modify, deploy, and maintain.Services can be developed, tested, and deployed separately.3. Built-in Transport Layer SupportSupports various transport layers like Redis, RabbitMQ, NATS, Kafka, MQTT, gRPC, and more.Enables event-driven communication, improving performance and resilience.4. High PerformanceEfficient handling of requests through asynchronous communication.Reduces load on individual services by distributing workloads.5. Improved Fault ToleranceIf one microservice fails, others continue working, reducing the impact on the system.Supports circuit breakers and retries to handle failures effectively.6. Technology AgnosticEach microservice can use different technologies or programming languages.NestJS allows seamless integration with external APIs and services.7. Better Team ProductivityDifferent teams can work on separate microservices without dependency bottlenecks.Faster development cycles due to modular architecture.8. Enhanced MaintainabilityClear separation of concerns makes debugging and updating code easier.Smaller, well-defined services reduce technical debt.9. Security and IsolationEach service has its own security boundaries, reducing the impact of vulnerabilities.Allows implementation of zero-trust security models at the service level.10. Support for Domain-Driven Design (DDD)Helps structure services based on business logic and domain requirements.Encourages clean and maintainable architecture.
