|
|
|
|
通过 CLI 快速地创建一个空插件,命令如下:
|
2022-09-19 09:23:01 +08:00
|
|
|
|
|
|
|
|
|
```bash
|
2023-09-12 22:39:23 +08:00
|
|
|
|
yarn pm create @my-project/plugin-hello
|
2022-09-19 09:23:01 +08:00
|
|
|
|
```
|
|
|
|
|
|
2023-09-12 22:39:23 +08:00
|
|
|
|
插件所在目录 `packages/plugins/@my-project/plugin-hello`,插件目录结构为:
|
2022-09-19 09:23:01 +08:00
|
|
|
|
|
2022-10-31 11:52:17 +08:00
|
|
|
|
```bash
|
2023-09-12 22:39:23 +08:00
|
|
|
|
|- /packages/plugins/@my-project/plugin-hello
|
2022-09-19 09:23:01 +08:00
|
|
|
|
|- /src
|
2022-10-31 11:52:17 +08:00
|
|
|
|
|- /client # 插件客户端代码
|
|
|
|
|
|- /server # 插件服务端代码
|
2022-09-19 09:23:01 +08:00
|
|
|
|
|- client.d.ts
|
|
|
|
|
|- client.js
|
2022-10-31 11:52:17 +08:00
|
|
|
|
|- package.json # 插件包信息
|
2022-09-19 09:23:01 +08:00
|
|
|
|
|- server.d.ts
|
|
|
|
|
|- server.js
|
|
|
|
|
```
|
|
|
|
|
|
2023-09-12 22:39:23 +08:00
|
|
|
|
访问插件管理器界面,查看刚添加的插件,默认地址为 http://localhost:13000/admin/pm/list/local/
|
