Technologies

LET Portal is built by using SPA architecture. That means I am using .NET Core Web API as Back end service and Angular as Front end page. These databases below are using to install and query. Docker helps you to run quickly on Windows or Linux (Ubuntu 😃)

• ✅ .NET Core 3.1
• ✅ Angular 9, Material Angular
• ✅ Docker
• ✅ MongoDB 4
• ✅ SQL Server 2012+
• ✅ MySQL
• ✅ PostgreSQL

High Level Design

According to an architecture above, LET Portal has {==two components and one 3rd-party==}. There are:

• SPA Web: Angular 9, our main front-end web application. It will connect to Saturn to perform APIs.
• Saturn: .NET Core 3.1, our main back-bone web service. It will provide four big features: Identity, Portal, Chat&Video, Microservices
• Proxy Server: Nginx

Saturn

In the architecture above, Saturn consists of four main features: Identity, Portal, Chat&Video and Microservice.

• Identity and Portal: work with Web API, that mean they expose the public endpoint to be called.
• Chat&Video: works under SignalR, that mean they expose the real-time connection between Client and Server.
• Microservice: work under gRPC, that mean they only expose the private endpoint in HTTP/2 protocol to be called via inter-service communication.

Highlight Features

Standard Form

Quickly create the form by scanning the data from the database. Ex: If you have a SELECT clause, you want to convert it into the form. Just paste it into Standard Builder and automatically create the Form!

Array

Quickly create the gridview which can manipulate array data. Ex: If you have a SELECT clause with returning multiple records, you want to convert it into the gridview to manipulate it. Just paste it into Standard Builder and automatically create the GridView!

• Observe CUD in a list
• Detect dirty object
• Allow to separate INSERT, UPDATE and DELETE command when updating to Database.

Tree

Quickly create the tree which can manipulate tree data. Ex: You have a nested data such as menu, you want to canvas it with Builder!
