# Commands # 命令行
## 简介
NocoBase Server Application 除了用作 WEB 服务器以外,也是个强大可扩展的 CLI 工具。
新建一个 `app.js` 文件,代码如下:
```ts
const Application = require('@nocobase/server');
// 此处省略具体配置
const app = new Application({/*...*/});
app.runAsCLI();
```
`runAsCLI()` 方式运行的 app.js 是一个 CLI在命令行工具就可以像这样操作了
```bash
node app.js install # 安装
node app.js start # 启动
```
为了更好的开发、构建和部署 NocoBase 应用NocoBase 内置了许多命令,详情查看 [NocoBase CLI](/api/cli) 章节。
## 自定义 Command
NocoBase CLI 的设计思想与 [Laravel Artisan](https://laravel.com/docs/9.x/artisan) 非常相似都是可扩展的。NocoBase CLI 基于 [commander](https://www.npmjs.com/package/commander) 实现,可以这样扩展 Command
```ts
app
.command('echo')
.option('-v, --version');
.action(async ([options]) => {
console.log('Hello World!');
if (options.version) {
console.log('Current version:', app.getVersion());
}
});
```
这个方法定义了以下命令:
```bash
yarn nocobase echo
# Hello World!
yarn nocobase echo -v
# Hello World!
# Current version: 0.7.4-alpha.7
```
更多 API 细节可参考 [Application.command()](/api/server/application#command) 部分。
## 示例
### 定义导出数据表的命令
如果我们希望把应用的数据表中的数据导出成 JSON 文件,可以定义一个如下的子命令:
```ts
import path from 'path';
import * as fs from 'fs/promises';
class MyPlugin extends Plugin {
load() {
this.app
.command('export')
.option('-o, --output-dir')
.action(async (options, ...collections) => {
const { outputDir = path.join(process.env.PWD, 'storage') } = options;
await collections.reduce((promise, collection) => promise.then(async () => {
if (!this.db.hasCollection(collection)) {
console.warn('No such collection:', collection);
return;
}
const repo = this.db.getRepository(collection);
const data = repo.find();
await fs.writeFile(path.join(outputDir, `${collection}.json`), JSON.stringify(data), { mode: 0o644 });
}), Promise.resolve());
});
}
}
```
注册和激活插件之后在命令行调用:
```bash
mkdir -p ./storage/backups
yarn nocobase export -o ./storage/backups users
```
执行后会生成 `./storage/backups/users.json` 文件包含数据表中的数据。
## 小结
本章所涉及示例代码整合在 [packages/samples/command](https://github.com/nocobase/nocobase/tree/main/packages/samples/command) 包中,可以直接在本地运行,查看效果。
