Winston 未在 node.js 中记录调试级别

Question

我不是运行 VS Code 上的这个，只是一个普通的终端。

当我将具有不同级别的对象传递给 winston 时，它们都按预期输出 - 除了 debug

import { Logger, format, createLogger, transports } from "winston";

export const exampleLogger = (): Logger => {
  return createLogger({
    transports: [new transports.Console()],
    format: format.combine(
      format((info) => {
        info.level = info.level.toUpperCase();
        return info;
      })(),
      format.json(),
    ),
  });
}

import { exampleLogger } from './example'

const logger = exampleLogger();

const infoExample = {
  timestamp: '2021-06-25T07:06:03.901Z',
  level: 'info',
  message: 'this works fine'
}
logger.log(infoExample)

const debugExample = {
  timestamp: '2021-06-25T07:06:03.901Z',
  level: 'debug',
  message: 'this outputs nothing'
}
logger.log(debugExample)

const errorExample = {
  timestamp: '2021-06-25T07:06:03.901Z',
  level: 'error',
  message: 'this works fine'
}
logger.log(errorExample)

执行

$ npx ts-node test.ts
{"timestamp":"2021-06-25T07:06:03.901Z","level":"INFO","message":"this works fine"}
{"timestamp":"2021-06-25T07:06:03.901Z","level":"ERROR","message":"this works fine"}

好的，看来我误解了有关默认日志记录级别的文档。 As stated in this issue，我需要告诉winston它应该输出某些日志级别

import { Logger, format, createLogger, transports } from "winston";

export const exampleLogger = (): Logger => {
  return createLogger({
    transports: [new transports.Console({ level: 'debug' })],
    format: format.combine(
      format((info) => {
        info.level = info.level.toUpperCase();
        return info;
      })(),
      format.json(),
    ),
  });
}
