EFurni - Example of Scalable Monolith
Summary
Example of furniture themed e-commerce backend / frontend written with Asp Net Core and Blazor Web Assembly
Preview: Here
Motivation
Creating an example of three tier monolith within e-commerce concept that implements essential features of it's business such as order, checkout, basket, etc project's goals are being example of following topics
- Scalable monolith
- Proper implementation of Clean Architecture
- Application of S.O.L.I.D principles
- 3 Tier UI, Backend, Database approach
- N Layer sevice based approach
- Basics of distributed caching
- RESTFull Api Design
Current Tech stack
- ASP Net Core
- Blazor Web Assembly
- Razor Pages
- Entity Framework Core
- Docker
- Kubernetes
- Redis
- Postgresql
- Azure Cloud
Guide-level explanation
The Current structure of backend have following layers Service, Data access, Presentation layer
- Presentation layer, that will capture all requests from users via rest over http then when user made request to endpoint it sanitizes and validates user's input before the call service layer
- Service layer, is where our business logic lives also the facade for our domain entities
- Data Access layer, is where the all the persistence operations are handling
Issues
-
Dirty entities created by EF Core such as all the business entities scaffolded by EF Core and it causes to business entity's ruled by EF Core's conventions which is preventable with manuel mapping but I think this kills the concept of EF Core
-
Authentication method is fairly simple and monolithic it uses token based centralized authentication so there is no third party support in it
-
Doesn't met GDPR compliance
-
Lack of unit and integration test
How to setup
Linux
Just run the ./bootup.sh external dependencies not included
Windows
Prerequisites
- Redis
- Postgresql (preferably version 11 or higher)
- PostGIS
- .NET Core 5
Post installation
After installing dependencies, edit the connection string in config file and ready to go.
Azure
Azure scripts allows to automate independent deployment of backend and frontend also external dependencies as well (free tier compatible).
Scripts for deployment
- DeployBackend.sh
- DeployFrontend.sh
- DeployPostgres.sh
- DeployRedis.sh
Scripts for creating AKS cluster and other resources (in order)
- CreateServicePrincipal.sh
- CreateAKSCluster.sh
