I am using Winston logger inside NestJS application but when logs are writing in file then some unwanted characters are also get appended to my logs.
Below are the logs from log file:
[92m[MyApp][39m [33mInfo[39m 16/3/2022, 7:03:52 pm [92mHello[39m - {}
Below is my Winston configuration:
import { Module } from '@nestjs/common';
import { WinstonModule,utilities as nestWinstonModuleUtilities } from 'nest-winston';
import * as winston from 'winston';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import * as path from 'path';
@Module({
imports: [ WinstonModule.forRoot({
format: winston.format.combine(
winston.format.timestamp(),
winston.format.json(),
winston.format.simple(),
nestWinstonModuleUtilities.format.nestLike('MyApp', { prettyPrint: true }),
),
transports: [
new winston.transports.File({
dirname: path.join(__dirname, '../log/info/'), //path to where save logging result
filename: 'info.txt', //name of file where will be saved logging result
level: 'info',
}),
],
}),],
controllers: [AppController],
providers: [AppService],
})
export class AppModule {}
How can I remove these characters from my logs?
Add format like this. You can change replace character whatever you want. This code is for example.
new winston.transports.File({
dirname: path.join(__dirname, '../log/info/'), //path to where save logging result
filename: 'info.txt', //name of file where will be saved logging result
level: 'info',
format: format.combine(
format.printf((i) => i.message.replace('e', '')),
),
}),
Or if you want to delete all special character use this code
new winston.transports.File({
dirname: path.join(__dirname, '../log/info/'), //path to where save logging result
filename: 'info.txt', //name of file where will be saved logging result
level: 'info',
format: format.combine(
format.printf((i) => i.message.replace(/[e]/g, '')),
),
}),
