Node.js日志分割与归档方法

npm install winston-daily-rotate-file

const winston = require('winston');
const DailyRotateFile = require('winston-daily-rotate-file');

const transport = new DailyRotateFile({
  filename: 'application-%DATE%.log',
  datePattern: 'YYYY-MM-DD-HH',
  zippedArchive: true,
  maxSize: '20m',
  maxFiles: '14d'
});

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    transport
  ]
});

logger.info('Hello, world!');

npm install pino pino-pretty pino-daily-rotate-file

const pino = require('pino');
const pinoPretty = require('pino-pretty');
const pinoDailyRotateFile = require('pino-daily-rotate-file');

const logger = pino({
  level: 'info'
}, pinoDailyRotateFile({
  period: '1d',
  dir: 'logs',
  prefix: 'application'
}));

logger.info('Hello, world!');

// 如需美化控制台输出格式，可配合使用 pino-pretty
pinoPretty({ colorize: true }).pipe(process.stdout);
