How to setup the path in winston and app.module.ts for Linux and Windows localhost
To set up the path in a winston
logger configuration and app.module.ts
file for both Linux and Windows localhost environments, you can follow these general guidelines:
Winston Logger Configuration:
In your Winston logger configuration file (e.g.,logger.config.js
), define the log file path based on the operating system.javascriptconst winston = require('winston');
const path = require('path');
// Determine the log file path based on the operating system
const logFilePath = process.platform === 'win32'
? path.join('C:', 'logs', 'app.log')
: path.join('/var', 'log', 'app.log');
const logger = winston.createLogger({
transports: [
new winston.transports.File({ filename: logFilePath }),
// Add more transports as needed
],
});
module.exports = logger;
In this example, the log file path is set to
C:\logs\app.log
for Windows (win32
platform) and/var/log/app.log
for Linux.App Module Configuration:
In yourapp.module.ts
file (assuming it's a TypeScript project), you can use thepath
module to determine the appropriate log file path.typescriptimport { Module } from '@nestjs/common';
import { Logger } from 'winston';
import { join } from 'path';
@Module({
// Module configuration
})
export class AppModule {
constructor(private logger: Logger) {
// Determine the log file path based on the operating system
const logFilePath = process.platform === 'win32'
? join('C:', 'logs', 'app.log')
: join('/var', 'log', 'app.log');
this.logger.info(`Log file path: ${logFilePath}`);
}
}
In this example, the log file path is set to
C:\logs\app.log
for Windows (win32
platform) and/var/log/app.log
for Linux. The log file path is then logged using the Winston logger instance.
Remember to adjust the log file paths as per your requirements and the actual location you want to store the log files.
By following these guidelines, your Winston logger configuration and app module will handle the appropriate log file paths based on the operating system when running in a Linux or Windows localhost environment.
