Node live log

Module to generate logs in real time through socket.io.

Install

npm i node-live-log

Usage

In your application

const log = require("node-live-log")("Your module name or identifier");
log.info("Log with args", "Arg1", "Arg2", "...Args");
log.warn(`Warn log`);
log.error("Error log");
log.debug("Debug log");

To view the logs generated by your application you need to write a client. Basically you can do:

const io = require("socket.io-client");
const client = io("ws://localhost:3010");

client.on("log-info", (msg) => {
  console.log(msg);
});

client.on("log-warn", (msg) => {
  console.log(msg);
});

client.on("log-error", (msg) => {
  console.log(msg);
});

client.on("log-debug", (msg) => {
  console.log(msg);
});

You can consult a more advanced example at this link advanced client
