Introduction to Logupdate

Logupdate is a powerful library designed to streamline and enhance logging in your applications. With a variety of APIs, it enables developers to create efficient and structured logs. This guide provides an overview of Logupdate’s features, including code snippets and a comprehensive application example.

Getting Started

To begin using Logupdate, install it via npm:

  npm install logupdate

Basic Usage

Create a simple log with Logupdate:

  const logUpdate = require('logupdate');

  logUpdate('Simple log message');

Updating Log Messages

Update the existing log message:

  logUpdate('First log message');
  setTimeout(() => {
    logUpdate('Updated log message');
  }, 2000);

Clearing Logs

Clear the current log message:

  logUpdate.clear();

Log with Formatting

Add some formatting to the log message:

  logUpdate(`
    \x1b[32mSuccess:\x1b[0m Server started
  `);

Log With Spinner

Display a spinner while a process is ongoing:

  const ora = require('ora');
  const spinner = ora('Loading...').start();

  setTimeout(() => {
    spinner.stop();
    logUpdate('Loading complete');
  }, 3000);

Multiple Log Streams

Handle multiple log streams simultaneously:

  const log1 = 'Stream 1: Data loading...';
  const log2 = 'Stream 2: Connection established...';

  logUpdate(`
    ${log1}
    ${log2}
  `);

Application Example

Let’s build a simple Node.js application that uses the APIs mentioned above.

  const logUpdate = require('logupdate');
  const ora = require('ora');

  let counter = 0;
  const spinner = ora('Starting application...').start();

  setInterval(() => {
    counter++;
    logUpdate(`Counter: ${counter}`);
  }, 1000);

  setTimeout(() => {
    spinner.stop();
    logUpdate.clear();
    logUpdate('Application stopped');
  }, 10000);

In this example, we use Logupdate to create a counter application that updates the log every second. The spinner indicates that the application has started, and after 10 seconds, we stop the spinner, clear the log, and finally log a message stating that the application has stopped.

By mastering the Logupdate library, you can significantly improve the logging mechanism of your applications. The above examples demonstrate various ways to implement and customize log messages using Logupdate’s rich feature set.
