About

A very simple logger.

Install

npm install @xan105/log

Usage example

import Logger from "@xan105/log";
const debug = new Logger({
  console: true,
  file: "./example.log",
  appendToFile: false //create a new file
});

debug.log("this is a string");
debug.log("this is a string","info");
debug.info("this is a string");
debug.warn("this is a warning");
debug.error("this is an error");

Log in the same file from different places

//Wrapper "log.js"
import Logger from "@xan105/log";
const debug = new Logger({
  console: true,
  file: "./example.log"
});
export { debug };

//file a "a.js"
import { debug } from "./log.js";
debug.log("this is a");

//file b "b.js"
import { debug } from "./log.js";
debug.log("this is b");

//Both output in ./example.log
