# DataLoader-Source-Explore

## Quick Start

```bash

yarn

yarn dev

```

打开链接：[http://localhost:7878/](http://localhost:7878/)

使用 [common.graphql](graphql/common.graphql) 的语句发起查询，此操作预期将重复调用 `getUserById` `getPetsByIds` 方法，见终端输出。

使用 [dataloader.graphql](graphql/dataloader.graphql) 的语句发起查询，此操作预期将仅调用批查询方法`getUsersByIds` `getPetsByIds`，见终端输出。

通过最上方的导入来切换示例使用的 DataLoader 实现：

```typescript

// TS 版本

import DataLoader from "./dataloader";

// NPM 版本

import DataLoader from "dataloader";

// 迷你实现版本

import DataLoader from "./tiny";

```
