#### 例子 examples

- 使用配置`config.dev.json`开发调试, dev with `config.dev.json`

```bash
npx miniprogram-build --config=config.dev.json
```

- 使用`config.prod.json`生产环境开启优化重新编译,rebuild for production with `config.prod.json`

> 如果 `production` 参数未指定, 环境变量中 NODE_ENV 为 `production`或`prod`时同样置为 `true`

```bash
npx miniprogram-build build --config=./config.prod.json --production
```

- 编译替换`{{APP_ID}}`为 1234567, compile the source and replace template var _{__{_`APP_ID`_}__}_ with 123456

```bash
npx miniprogram-build compile --var.APP_ID=1234567
```

### 默认配置文件 default config

```json
{
  "production": false,
  "src": "src",
  "dist": "dist",
  "assets": "assets",
  "copy": "",
  "exclude": [],
  "tsconfig": "tsconfig.json",
