[Suggestion/FR] Selective logging to telegram

[ivanmarban]

I'm not sure if I understand correctly but does this feature of winston do what you are requesting ?

Could you provide a complete example of your needs ?

[ivanmarban]

Let me know if this is what are you looking for:

const { createLogger, format, transports } = require('winston')
const TelegramLogger = require('winston-telegram')

// Ignore log messages if they have { private: true }
const ignorePrivate = format((info, opts) => {
  if (info.private) { return false }
  return info
})

const logger = createLogger({
  format: format.combine(
    ignorePrivate(),
    format.json()
  ),
  transports: [
    new transports.Console(),
    new TelegramLogger({
      token: 'TOKEN',
      chatId: 'CHAT_ID',
      level: 'error',
      unique: true
    })
  ]
})

// Outputs: {"level":"error","message":"Public error to share"}
logger.log({
  level: 'error',
  message: 'Public error to share'
})

// Messages with { private: true } will not be written when logged.
logger.log({
  private: true,
  level: 'error',
  message: 'This is super secret - hide it.'
})

In a way yes but I was more thinking - not to ignore messages, but rather to selectively send them to Telegram, if {private: true} let's say in this instance. I know at a previous job we had this, just a slack bot instead of TG.
It would be invoked like this: logger.info('Login Success', { channel: '@nico' }). <-- This would go to channel specified.
But logger.info('cache-hit-1337') <-- this would only go to console.

The examples are contrived, but hopefully it's clear. 😓

There is an example for NestJS?

[ivanmarban]

Sorry @fr20587 but I'm not familiar with NestJS.

@nicoandmee I'm sorry but I wasn't able to find time to take a look at your proposition for the moment.

@nicoandmee you can try my fork (wip):
https://github.com/WildEgor/winston-telegram

https://github.com/WildEgor/winston-telegram/blob/develop/examples/simple-log/src/index.ts#L26

[ivanmarban]

After checking again @nicoandmee request, from my understanding, I think that there are two things:

• Be able to selectively choose what transport to use to log the message with a unique logger defined. Not possible AFAIK
• Be able to selectively choose what TG chatId should the log message be sent. That is the example from @WildEgor fork.

I'm closing this issue as there wasn't any activity or response since my last comment.

If anyone finds interesting to investigate and implement the second point, fell free to open a new issue.
