# v0.9.0：NocoBase 的 Logging 系统
|
||
|
||
## `@nocobase/logger`
|
||
|
||
基于 Winston 实现，提供了便捷的创建 logger 实例的方法。
|
||
|
||
```ts
|
||
const logger = createLogger();
|
||
logger.info('Hello distributed log files!');
|
||
|
||
const { instance, middleware } = createAppLogger(); // 用于 @nocobase/server
|
||
app.logger = instance;
|
||
app.use(middleware);
|
||
```
|
||
|
||
## 新增的环境变量
|
||
|
||
logger 相关环境变量有：
|
||
|
||
- [LOGGER_TRANSPORT](/api/env#logger_transport)
|
||
- [LOGGER_BASE_PATH](/api/env#logger_base_path)
|
||
|
||
## Application 的 logger 配置
|
||
|
||
```ts
|
||
const app = new Application({
|
||
logger: {
|
||
async skip(ctx) {
|
||
return false;
|
||
},
|
||
requestWhitelist: [],
|
||
responseWhitelist: [],
|
||
transports: ['console', 'dailyRotateFile'],
|
||
},
|
||
})
|
||
```
|
||
|
||
更多配置项参考 [Winston 文档](https://github.com/winstonjs/winston#table-of-contents)
|
||
|
||
## app.logger & ctx.logger
|
||
|
||
ctx.logger 带有 reqId，整个 ctx 周期里都是一个 reqId
|
||
|
||
```ts
|
||
ctx.logger = app.logger.child({ reqId: ctx.reqId });
|
||
```
|
||
|
||
`app.logger` 和 `ctx.logger` 都是 Winston 实例，详细用法参考 [Winston 文档](https://github.com/winstonjs/winston#table-of-contents)
|
||
|
||
|
||
## 自定义 Transports
|
||
|
||
除了 Winston 的方式以外，NocoBase 还提供了一种更便捷的方式
|
||
|
||
```ts
|
||
import { Transports } from '@nocobase/logger';
|
||
|
||
Transports['custom'] = () => {
|
||
return new winston.transports.Console();
|
||
};
|
||
|
||
const app = new Application({
|
||
logger: {
|
||
transports: ['custom'],
|
||
},
|
||
})
|
||
```
