# 内置常用资源操作
# Built-in Common Resource Actions
## 概览
## Overview
针对常用的 CRUD 等数据资源的操作，NocoBase 内置了对应操作方法，并通过数据表资源自动映射相关的操作。
NocoBase has built-in operation methods for commonly used actions of data resources, such as CRUD, and automatically maps related actions through data table resources.
```javascript
import { Application } from "@nocobase/server";
@ -12,36 +12,34 @@ const app = new Application({
dialect: 'sqlite',
storage: './db.sqlite',
},
registerActions: true // 注册内置资源操作，默认为 True
registerActions: true // Register built-in resource actions, true by default
});
```
Built-in actions are registered to the `resourcer` instance in `application`. Generally, built-in actions are not called directly unless you need to extend the default action, then you can call the default method within a custom action method.
内置的操作方法都是注册在 `application` 中的 `resourcer` 实例上。
通常情况下无需直接调用内置的 action 方法，在需要扩展默认操作行为时，可以在自定义的操作方法内调用默认方法。
## 资源操作
## Resource Actions
### `list()`
获取数据列表。对应资源操作的 URL 为 `GET /api/<resource>:list`。
Get a list of data. The URL for the corresponding resource action is `GET /api/<resource>:list`.

**Example**
当需要提供一个查询数据列表的接口，但不是默认以 JSON 格式输出时，可以基于内置默认方法进行扩展：
When there is a need to provide an interface for querying a list of data that is not output in JSON format by default, it can be extended based on the built-in default method:
