What node library should I use for managing logs?

Question

I am getting a set of logs from one application (in a txt file) and I have to separate, process and then send them one by one to another app. The format of the logs that I'm receiving is like this:

2019-05-07 10:46:49,532 [6] INFO App1 - Message1
2019-05-07 10:46:51,532 [6] INFO App1 - Message2

And I have to send them one by one as a JSON object in this format:

{
"timestamp":"2018-07-12T17:53:44.613+05:30",
"senderApp":"ThisApp",
"senderUser":"Mike",
"logLevel":"Error",
"logMessage":"This is the error we received!"
} 

Is there any library that could help me? Thanks in advance!

Logstash is a tool to process and transform data from multiple sources.

As you might guess from the name, is mainly used to extract and format data from logs and send it to a storage (e.g: Elastic Search).

It is configured using a DSL with the following components:

• inputs: it could be a file in you example

• filters: for instance, grok, that allows you to extract data using regular expressions

• outputs: also a file for your case.
