为 winston 日志库的打造的一些简单元件。
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!"),
});

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.error({

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.silly({ context, message: "Hello Yiu!" });
nestLogger.error({
context,
message: "Hello Yiu!",
error: new Error("Error Yiu!"),
});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",
});
