Plugin Architecture for a Trading Application

This project demonstrates how to implement a plugin architecture in a trading application. The architecture allows dynamic user interfaces for different types of users by using plugins. Instead of hardcoding logic for each user type, we use a flexible, modular approach, making the system easier to maintain, extend, and scale.

Introduction

In this project, the Plugin Architecture is applied to handle various user types within a trading application. Typically, developers might use conditional logic to handle different user scenarios, but as the project grows, this becomes hard to maintain. Plugin architecture provides a cleaner solution by separating concerns and allowing new features to be added as independent modules.

Features

• Modular architecture using plugins
• Dynamically render user-specific views
• Easier code maintenance and scalability
• Clean separation of logic with the use of protocols and extensions

Installation

To run this project:

1. Clone the repository:

   git clone https://github.com/codedeman/PluginArchitecture.git

2. Open the project in Xcode:

   open PluginArchitecture.xcodeproj

3. Build and run the app in a simulator or on a device.

Usage

1. Plugin Definition: Define a plugin by conforming to the Plugin protocol. Each plugin will have an associated view that will be dynamically rendered.

   protocol Plugin: Identifiable {
       associatedtype PluginView: View
       var id: UUID { get }
       var name: String { get }
       var imageName: String { get }
       @ViewBuilder func render() -> PluginView
   }

2. Sample Plugin: Create plugins that handle different user use cases.

   struct SamplePlugin: Plugin {
       let id = UUID()
       let name: String
       let imageName: String
       
       func render() -> some View {
           VStack {
               Image(systemName: imageName)
               Text(name)
           }
       }
   }

3. Host View: The PluginHostView will handle displaying the plugins in a horizontal or vertical layout.

   struct PluginHostView: View {
       var shortcuts: [AnyPlugin] // Horizontal list
       var verticalPlugins: [AnyPlugin] // Vertical list
       
       var body: some View {
           VStack {
               ScrollView(.horizontal) {
                   HStack {
                       ForEach(shortcuts) { plugin in
                           plugin.render()
                       }
                   }
               }
               LazyVGrid(columns: [GridItem(.flexible()), GridItem(.flexible())]) {
                   ForEach(verticalPlugins) { plugin in
                       plugin.render()
                   }
               }
           }
       }
   }

Architecture

The plugin architecture is based on the following principles:

• Plugins: Encapsulate the user-specific logic and view rendering.
• Protocol-Oriented: Define a Plugin protocol that all user-specific modules conform to.
• Dynamic Layout: Use ScrollView for horizontal lists and LazyVGrid for vertical lists.

API Design

If plugins are loaded from an API, the following sample API response format is suggested:

{
    "plugins": [
        {
            "name": "Marketplace",
            "image": "cart",
            "type": "vertical"
        },
        {
            "name": "Friends",
            "image": "person.2",
            "type": "horizontal"
        }
    ]
}

Plugins will be dynamically created based on API responses.

Plugin Examples

Here are some examples of plugins:

• Friends Plugin: Displays a list of friends.
• Marketplace Plugin: Shows a marketplace for trading.
• Professional Dashboard Plugin: Renders a dashboard for professionals.
