Using YARN:

$ yarn add logitt

Usage

Logitt provides a straightforward logger and an easy-to-use interface for viewing logs. Here's how to get started:

• Configuration: Set up your environment variables before using the library.

• Development Mode: By default, Logitt operates in "development" mode, displaying all logs in the console using Consola

• Production Mode: To save logs to files (stored in the "/logs" folder), update your environment variables as follows:

NODE_ENV="production"

1. Instantiate

Logitt employs the Singleton design pattern. You can configure the logger by changing the URL of the UI Explorer or by enabling/disabling tracing.

const { Logitt } = require("logitt");

// Default configuration options
const options = {
  // Enable tracing to identify the source of the log
  trace: true,
  // Set the URL path for the UI Explorer
  route: "/logs",
};

// Create a new instance with custom options, if not already created
const loggy = Logitt.getLogger(options);

// Create a new instance with default options
const loggy = Logitt.getLogger();

2. Logging

Logitt provides 4 logging levels: SUCCESS, DEBUG, WARNING, and ERROR.

• SUCCESS: Always logs to the console, regardless of the environment.
• DEBUG: For detailed debugging information.
• WARNING: For warning messages.
• ERROR: For error messages.

Here's how to use them:

loggy.warn("Warning occured here");
loggy.error("Error occured here");
loggy.debug("Debug occured here");
loggy.success("Success occured here");

// You can also log directly using the singleton instance
// Logitt.getLogger().warn("Warning occured here")

To include additional context or metadata with your logs:

loggy.error("Unable to create a new user", {
  name: "John Doe",
  email: "[email protected]",
  phone: null,
});

3. UI Explorer

To access the UI Explorer and view your logs, you need to set your credentials as environment variables:

LOGITT_USERNAME=your_username
LOGITT_PASSWORD=your_password

3.1. No Framework

const { Logitt } = require("logitt");
const http = require("http");

const loggy = Logitt.getLogger();

http.createServer(loggy.render).listen(PORT, () => {
  consola.start(`Server is running on port ${PORT} ...\n`);
});

3.2. ExpressJS

const { Logitt } = require("logitt");
const express = require("express");

const app = express();

app.get("/logs", Logitt.getLogger().render);

// Custom URL
app.get("/my-logs", Logitt.getLogger({ route: "/my-logs" }).render);

3.3. NestJS

import { Controller, Get, Req, Res } from "@nestjs/common";
import { Request, Response } from "express";
import { Logitt } from "logitt";

@Controller()
export class AppController {
  constructor() {}

  @Get("/logs")
  getLogs(@Req() req: Request, @Res() res: Response) {
    let logitt = Logitt.getLogger();
    logitt.render(req, res);
  }

  // Custom URL
  @Get("/my-logs")
  getLogs(@Req() req: Request, @Res() res: Response) {
    let logitt = Logitt.getLogger({ route: "/my-logs" });
    logitt.render(req, res);
  }
}
