- Bu video, Moleculer framework'ün nasıl kullanılacağını gösteren bir eğitim içeriğidir. Eğitmen, Moleculer'in ne olduğunu ve avantajlarını açıklayarak başlıyor.
- Video, Moleculer framework'ün temel kavramlarını ve nasıl kullanılacağını adım adım gösteriyor. Önce gateway ve helper gibi temel servislerin nasıl oluşturulacağı, ardından Docker Compose ile dağıtım yapılandırması gösteriliyor. Eğitmen, gateway servisinin gelen istekleri nasıl yönlendirdiğini, helper servisinin rastgele sayı ürettiğini ve bu sayının nasıl geri döndürüldüğünü kod örnekleriyle açıklıyor. Video, Moleculer framework'ü kullanarak dağıtılmış uygulamalar geliştirmek isteyen geliştiriciler için faydalı bir kaynak niteliğindedir.
- 00:01Introduction to Moleculer
- Moleculer is an open-source service framework that provides tools for developing distributed applications and microservices.
- It allows developers to focus only on application logic, supporting Java and Ruby.
- Moleculer offers scalability, dynamic service discovery, and registration, providing everything needed to build distributed applications.
- 01:54Video Objectives
- The video will demonstrate how to set up a basic Moleculer project, make requests, and use a gateway service.
- It will show how to expose services publicly using an HTTP gateway and how to use Docker Compose to deploy services.
- The example project consists of a gateway service that handles HTTP requests and a helper service that generates random numbers.
- 03:29Moleculer Concepts
- When the gateway service receives a request, it makes another request to the helper service to get a random number.
- The gateway service waits for the response from the helper service, adds the number to its response, and forwards it back to the client.
- Before diving into the code, the video explains some key concepts about distributed applications and deployment.
- 06:18Setting Up the Project
- The official Moleculer web page and documentation are used to create a new project.
- The project setup includes a gateway service, configuration for containers, and a message broker.
- The project structure includes a "visco" folder with some configuration files.
- 09:26Gateway Service Code
- The gateway service is a simple JavaScript file with some internal settings.
- It has only one action called "hello" that returns a message "hello mola".
- The service can be started using npm commands, and it listens on a specified port.
- 12:27Adding Helper Service
- A new helper service is created to generate random numbers.
- The helper service is called from the gateway service's "hello" action.
- The context object is used to pass information between services.
- 14:59Docker Compose Setup
- Docker Compose is used to run the application with multiple containers.
- Traefik is used as a reverse proxy and load balancer.
- Each service runs in its own container with specific configurations and Dockerfiles.
