Getting "Module not found: Can't resolve 'fs' " Error

See original GitHub issue

Hello, I am using NextJs for development, when I try to log my errors using this ( winston ), I got “Module not found: Can’t resolve ‘fs’” error. I don’t know what I did wrong here, Kindly someone give me a solution. Thanks in advance.

I post my logger config here,

`import { createLogger, format, transports } from 'winston';
import 'winston-daily-rotate-file';

const getLogger = (fileName = 'application') => {
    const fileLogTransport = new transports.DailyRotateFile({
        filename: `logs/${fileName}-%DATE%.log`,
        datePattern: 'YYYY-MM-DD',
        zippedArchive: true,
        maxSize: '20m',
        maxFiles: '30d',
    });

    const consoleTransport = new transports.Console({
        level: process.env.LOG_LEVEL,
        handleExceptions: false,
        json: false,
        colorize: true,
        format: format.printf((i) => `${i.message}`),
    });

    const logger = createLogger({
        level: 'error',
        format: format.combine(
            format.timestamp({
                format: 'YYYY-MM-DD',
            }),
            format.errors({ stack: true }),
            format.splat(),
            format.printf(
                ({ level, message, label = process.env.NODE_ENV, timestamp }) =>
                    `${timestamp} [${label}] ${level}: ${message}`
            )
        ),
        // defaultMeta: { service: 'my-app' },
        transports: [consoleTransport],
    });
    //
    if (process.env.NODE_ENV === 'development') {
        logger.add(fileLogTransport);
    }

    return logger;

};

export default getLogger();`
