title: 系统插件设计
description: FastGPT 系统插件设计方案
---
## 背景
原先 FastGPT 的各项功能均在 FastGPT 的 Next.js 的框架内,通过 Monorepo 的方式进行组织。
系统插件也作为一个 sub-repo 存在于 FastGPT/packages/plugin 下。
然而随着用户的增加,这种组织模式的弊端凸显:
1. 虽然 FastGPT 以每周一次的频率进行发版,但同样,系统插件必须伴随 FastGPT 的发版而发版,极大限制了系统插件的迭代速率。
2. 如果社区希望为 FastGPT 提供插件,则需要将 FastGPT 整个应用运行起来,并且直接向主仓库发起 PR。
3. 如果社区希望使用自定义的插件,则需要维护一个 FastGPT 的 fork 版本,并且手动维护更新和代码的合并,增加了开发的难度。
4. 由于 Next.js/webpack 的限制,无法在运行时挂载新的插件,实现热插拔。
## 设计方案
因而,我们决定将系统插件拆分出来,到一个独立的 repo 中。
[FastGPT-plugin](https://github.com/labring/fastgpt-plugin)
拆分出来,主要有如下的目的:
1. 解耦合,模块化:不只是 系统工具可以作为热加载的模块也可以是其他的插件例如知识库的插件RAG 等等。
2. FastGPT-plugin 可以快速迭代,版本不依赖于 FastGPTFastGPT-plugin 可以更高频率的发版,支持热插拔可以在不发版的情况下更新插件。
3. 降低开发复杂度(不需要运行 FastGPT 环境):贡献插件时只需要独立运行 FastGPT-plugin 中提供的调试套件即可。
4. 插件市场:后续可以实现插件市场,用户可以通过插件市场发布、获取自己需要的插件。
## 技术选型
1. 使用 ts-rest 作为 RPC 框架进行交互,提供 sdk 供 FastGPT 主项目调用
2. 使用 zod 进行类型验证
3. 用 bun 进行编译,每个工具编译为单一的 `.pkg` 文件,支持热插拔。
## 项目结构
- **modules**
- **tool** FastGPT 系统工具
- **api** 接口实现逻辑
- **packages** 系统工具目录(每一个都是一个 package
- getTime
- dalle3
- ...
- **type** 类型定义
- **utils** 工具
- **model** 模型预设
- **scripts** 脚本(编译、创建新工具)
- **sdk**: SDK 定义,供外部调用,发布到了 npm
- **runtime**: 运行时express 服务
- **lib**: 库文件,提供工具函数和类库
- **test**: 测试相关
系统工具的结构可以参考 [如何开发系统工具](/docs/introduction/guide/plugins/dev_system_tool)。
## 技术细节
### ts-rest 构建 contract自动构建 openapi 对象,导出 client
[ts-rest](https://ts-rest.com/) 是一个 ts 的 restful api 框架。构建 contract 后,可以根据 contract 的定义
编写处理逻辑,自动生成 openapi 对象、通过 createClient 导出 client 进行请求。
类似的 `tRPC` 也是一个 ts 的 RPC 框架。
然而 tRPC 使用自己的一套请求格式,导致其他工具不方便接入。而使用 ts-rest 本质就是对 RESTful API 的简单封装,也能直接生成 openapi 对象。
### zod 类型校验
我们使用 zod 来实现类型校验。
zod 可以实现在运行时的类型校验,也可以提供更高级的功能,例如参数转换,对象合并等。
### 使用 worker 实现插件的并行运行以及环境隔离
为了保证插件之间不会相互干扰同时提高并发处理能力FastGPT-plugin 采用 Worker 线程来实现插件的执行。每个工具在被调用时都会在独立的 Worker 中运行,
这带来几个重要的优势:
1. 环境隔离:每个插件都是一个独立的 Worker 进程,插件之间不会影响。
2. 并行处理:每个插件可以并行处理,提高整体性能。
### 使用 bun 进行打包
将插件 bundle 为一个单一的 `.pkg` 文件是一个重要的设计。这样可以将插件发布出来直接通过网络挂载等的形式使用。
## 未来规划
1. 可视化开发工具:提供可视化的插件开发和调试工具,降低开发门槛。
2. 插件市场:建立插件市场,允许开发者发布和分享自己的插件。
3. 更多插件类型除了系统工具外扩展到知识库插件、模型插件、RAG 插件等更多类型。
