ASP.NET Core lightweight plugin framework

Introduce

ASP.NET Core lightweight plugin framework

• Simple - Agreement is better than configuration, with minimal configuration to help you focus on your business
• Out of the box - Automatic front-end and back-end integration, two lines of code complete the integration
• Dynamic WebAPI - Each plug-in can add a Controller and have its own routing
• Front and back ends of the plug-in are separated - You can place the front-end files (index.html,...) under the plugin wwwroot folder, and then visit /plugins/pluginId/index.html
• Hot swap - Upload, install, enable, disable, uninstall, and delete without restarting the site; you can even add the HTTP request pipeline middleware at runtime through the plug-in, and there is no need to restart the site
• Dependency injection - You can apply for dependency injection in the construction method of the plug-in class that implements IPlugin. Of course, dependency injection can also be used in the controller construction method
• Easy to expand - You can write your own plug-in SDK, then reference the plug-in SDK, write extension plug-ins-custom plug-in hooks, and apply
• Widget - You can bury the extension point in the front end, and then insert the widget through the plugin
• No database required - No database dependency
• 0 intrusion - Nearly zero intrusion, does not affect your existing system
• Little reliance - Only rely on a third-party package (SharpZipLib for decompression)

Online demo

• http://plugincore.moeci.com/PluginCore/Admin
  • Username: admin Password: ABC12345
  • Online demo, most of the functions are limited, complete experience, please build it yourself, you can use the Docker below to quickly experience
  • Not the latest version

One minute integration

Recommended Use NuGet, Execute the following commands in the root directory of your project. If you use Visual Studio, then click Tools -> NuGet Package Manager -> Package Manager Console, make sure "Default project" It is the item you want to install, enter the command below to install it.

ASP.NET Core Project

PM> Install-Package PluginCore.AspNetCore

Modify the code in your ASP.NET Core application

Startup.cs

using PluginCore.AspNetCore.Extensions;

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers();

    // 1. Add PluginCore
    services.AddPluginCore();
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseHttpsRedirection();

    app.UseRouting();

    // 2. Use PluginCore
    app.UsePluginCore();

    app.UseAuthorization();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
    });
}

Now visit https://localhost:5001/PluginCore/Admin to enter PluginCore Admin https://localhost:5001 Need to be changed to your address

Notice

Please log in to PluginCore Admin, and for safety, modify the default user name and password in time:

App_Data/PluginCore.Config.json

{
	"Admin": {
		"UserName": "admin",
		"Password": "ABC12345"
	},
	"FrontendMode": "LocalEmbedded",
	"RemoteFrontend": "https://cdn.jsdelivr.net/gh/yiyungent/[email protected]/dist-cdn"
}

After the modification, it will take effect immediately, no need to restart the site, you need to log in to PluginCore Admin again

Docker experience

If you need to experience PluginCore locally, then here is an example(/examples)

docker run -d -p 5004:80 -e ASPNETCORE_URLS="http://*:80" --name plugincore-aspnetcore3-1 yiyungent/plugincore-aspnetcore3-1

Now you can visit http://localhost:5004/PluginCore/Admin

add:
If you use Docker Compose, you can refer to docker-compose.yml in the root directory of the warehouse

add:
Use ghcr.io

docker run -d -p 5004:80 -e ASPNETCORE_URLS="http://*:80" --name plugincore-aspnetcore3-1 ghcr.io/yiyungent/plugincore-aspnetcore3-1

Use

• Detailed Documentation(/docs) Document is under construction
• See examples(/examples)

Add plugin hook and apply

1. For example, custom plug-in hook: ITestPlugin

using PluginCore.IPlugins;

namespace PluginCore.IPlugins
{
    public interface ITestPlugin : IPlugin
    {
        string Say();
    }
}

2. Apply the hook where it needs to be activated, so that all enabled plug-ins that implement ITestPlugin will call Say()

using PluginCore;
using PluginCore.IPlugins;

namespace WebApi.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class TestController : ControllerBase
    {
        private readonly PluginFinder _pluginFinder;

        public TestController(PluginFinder pluginFinder)
        {
            _pluginFinder = pluginFinder;
        }

        public ActionResult Get()
        {
            //var plugins = PluginFinder.EnablePlugins<BasePlugin>().ToList();
            // All enabled plugins that implement ITestPlugin
            var plugins2 = _pluginFinder.EnablePlugins<ITestPlugin>().ToList();

            foreach (var item in plugins2)
            {
                // transfer
                string words = item.Say();
                Console.WriteLine(words);
            }

            return Ok("");
        }
    }
}

Custom frontend

PluginCore supports 3 front-end file loading methods

FrontendMode in the configuration file App_Data/PluginCore.Config.json

1. LocalEmbedded

• By default, embedded resources and front-end files are packaged into dll. In this mode, it is not easy to customize the front-end files. You need to modify the source code of PluginCore and recompile. It is not recommended

2. LocalFolder

• In the ASP.NET Core project that integrates PluginCore, create a new PluginCoreAdmin, and put the front-end files into this folder

3. RemoteCDN

• To use remote CDN resources, you can specify the url through the RemoteFrontend in the configuration file

注意:
更新 FrontendMode, 需重启站点后, 才能生效

补充

补充

开发插件只需要, 添加对 PluginCore.IPlugins 包 (插件sdk) 的引用即可，

当然如果你需要 PluginCore , 也可以添加引用

规范

1. 插件sdk

插件接口应当位于 PluginCore.IPlugins 命名空间，这是规范，不强求，但建议这么做，

程序集名不一定要与命名空间名相同，你完全在你的插件sdk程序集中，使用 PluginCore.IPlugins 命名空间。

2. 插件

插件程序集名(一般=项目(Project)名) 与 插件 info.json 中 PluginId 一致, 例如: Project: HelloWorldPlugin, PluginId: HelloWorldPlugin, 此项必须，否则插件无法加载 PluginId 为插件唯一标识

版本依赖

自 PluginCore.IPlugins-v0.8.0 起, PluginCore 项目重构, PluginCore 只包含核心插件逻辑, ASP.NET Core 需要使用 PluginCore.AspNetCore

下方为旧版依赖, 仅作存档

PluginCore.IPlugins
PluginCore
PluginCore.IPlugins.AspNetCore
PluginCore.AspNetCore
PluginCore.Template

环境

• 运行环境: .NET Core 3.1 (+)
• 开发环境: Visual Studio Community 2019
