yiu-winston-kit

为 winston 日志库的打造的一些简单元件。

1.日志样式

以下图片展示的是式执行如下日志操作后的结果：

logger.error({ context, message: "Hello Yiu!" });
logger.warn({ context, message: "Hello Yiu!" });
logger.info({ context, message: "Hello Yiu!" });
logger.http({ context, message: "Hello Yiu!" });
logger.verbose({ context, message: "Hello Yiu!" });
logger.debug({ context, message: "Hello Yiu!" });
logger.silly({ context, message: "Hello Yiu!" });
logger.error({
  context,
  message: "Hello Yiu!",
  error: new Error("Error Yiu!"),
});

1.3.文件

2.安装

pnpm i winston logform yiu-winston-kit

3.快速开始

const context = "packages/node-test/src/index.ts";

console.log("========== yiuLogger ==========");
const logger = yiuLoggerStater({ level: "silly" });
logger.error({ context, message: "Hello Yiu!" });
logger.warn({ context, message: "Hello Yiu!" });
logger.info({ context, message: "Hello Yiu!" });
logger.http({ context, message: "Hello Yiu!" });
logger.verbose({ context, message: "Hello Yiu!" });
logger.debug({ context, message: "Hello Yiu!" });
logger.silly({ context, message: "Hello Yiu!" });
logger.error({
  context,
  message: "Hello Yiu!",
  error: new Error("Error Yiu!"),
});

console.log("========== nestLogger ==========");
const nestLogger = nestLoggerStater({ level: "silly", silent: true });
nestLogger.error({ context, message: "Hello Yiu!" });
nestLogger.warn({ context, message: "Hello Yiu!" });
nestLogger.info({ context, message: "Hello Yiu!" });
nestLogger.http({ context, message: "Hello Yiu!" });
nestLogger.verbose({ context, message: "Hello Yiu!" });
nestLogger.debug({ context, message: "Hello Yiu!" });
nestLogger.silly({ context, message: "Hello Yiu!" });
nestLogger.error({
  context,
  message: "Hello Yiu!",
  error: new Error("Error Yiu!"),
});

4.自定义

其核心还是使用winston，如果你不太清楚下面的代码，那么你应该查看winston的文档。

其中的YiuLogger是为了规范日志函数的输入的，因为我不喜欢log有很多变种的入参。当然，如果你不建议你也可以不使用YiuLogger

import { createLogger, transports } from "winston";
import { format, Format } from "logform";
import { errStack, PrintfYiu, PrintfNest, YiuLogger } from "yiu-winston-kit";

const commonFormat: Format[] = [
  format.timestamp(),
  format.ms(),
  format.splat(),
  format.metadata({
    fillExcept: [
      "timestamp",
      "level",
      "context",
      "message",
      "ms",
      "splat",
      "error",
    ],
  }),
];

const winstonLogger = createLogger({
  level: "error",
  transports: [
    new transports.File({
      format: format.combine(...commonFormat, errStack(), format.json()),
      filename: "app.log",
    }),
    new transports.Console({
      format: format.combine(...commonFormat, new PrintfYiu().printf()),
    }),
    new transports.Console({
      format: format.combine(...commonFormat, new PrintfNest().printf()),
    }),
  ],
});

const yiuLogger = new YiuLogger(winstonLogger);

yiuLogger.log({
  level: "error",
  message: "Hello Yiu!",
  context: "custom.ts",
});
