What is load-script?

The load-script npm package is a utility for dynamically loading external JavaScript files into a web page. It provides a simple and efficient way to include scripts on the fly, which can be useful for various purposes such as loading third-party libraries, modularizing code, or conditionally loading scripts based on user interactions or other conditions.

What are load-script's main functionalities?

Basic Script Loading

This feature allows you to load an external JavaScript file by providing its URL. The callback function handles the success or failure of the script loading process.

const loadScript = require('load-script');

loadScript('https://example.com/script.js', function (err, script) {
  if (err) {
    console.error('Script loading failed:', err);
  } else {
    console.log('Script loaded successfully:', script.src);
  }
});

Loading Scripts with Attributes

This feature allows you to load a script with additional attributes such as 'async' and 'defer'. These attributes can control the script's loading behavior and execution timing.

const loadScript = require('load-script');

loadScript('https://example.com/script.js', { async: true, defer: true }, function (err, script) {
  if (err) {
    console.error('Script loading failed:', err);
  } else {
    console.log('Script loaded successfully with attributes:', script.src);
  }
});

Error Handling

This feature demonstrates how to handle errors when a script fails to load. The callback function receives an error object that can be used to log or handle the error appropriately.

const loadScript = require('load-script');

loadScript('https://example.com/nonexistent.js', function (err, script) {
  if (err) {
    console.error('Failed to load script:', err.message);
  } else {
    console.log('Script loaded successfully:', script.src);
  }
});
