Introduction to Gauge Instrumentation

Gauge is a versatile tool for measuring, monitoring, and displaying data in a variety of applications. As an essential instrument in many fields, understanding how to leverage Gauge APIs is crucial for developers aiming to build robust applications. This guide covers a wide range of Gauge APIs with practical examples and a comprehensive app example integrating these APIs.

Getting Started

First, ensure you have the Gauge library installed:

npm install gauge

Basic Gauge API Usage

Creating a Gauge

const Gauge = require('gauge');
const gauge = new Gauge();

Setting a Value

gauge.set(50); // Sets the gauge value to 50%

Showing and Hiding the Gauge

gauge.show('Loading', 50); // Shows the gauge with a message and value
gauge.hide(); // Hides the gauge

Updating the Gauge

gauge.pulse(); // Triggers a pulse animation
gauge.show('Processing', 70);

Advanced Usage

Custom Themes and Formatting

const themes = require('gauge/themes');
gauge.setTheme(themes.newTheme({
  activityIndicator: 'dots',
  progressbarTheme: 'smooth'
}));

Fullscreen Mode

gauge.enableFullscreen();
gauge.disableFullscreen();

Practical Application Example

Here’s a practical application that integrates all the aforementioned Gauge APIs:

const Gauge = require('gauge');
const themes = require('gauge/themes');

const gauge = new Gauge();
gauge.setTheme(themes.newTheme({
  activityIndicator: 'dots',
  progressbarTheme: 'smooth'
}));

function startLoading() {
  gauge.show('Initializing', 0);
  let progress = 0;
  const interval = setInterval(() => {
    progress += 10;
    gauge.show(`Loading...`, progress);
    if (progress >= 100) {
      clearInterval(interval);
      gauge.hide();
    }
  }, 1000);
}

startLoading();

Conclusion

The Gauge API provides extensive tools to enhance user experience with real-time progress tracking and feedback. Leveraging these APIs effectively can result in more engaging and transparent applications.
