Winston 未在 node.js 中記錄調試級別

Question

我不是在 VS Code 上運行它，只是一個普通的終端。

當我將具有不同級別的對象傳遞給 winston 時，它們都按預期輸出 - 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)

執行

$ 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，看起來我誤解了有關默認日志記錄級別的文檔。 如本期所述，我需要告訴溫斯頓它應該輸出某些日志級別

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(),
    ),
  });
}
