Working with npm objects across multiple files

My goal is to integrate the npm package for parallax (lax.js) into my project. The documentation states that in order to initialize it, the following code snippet should be included:

window.onload = function () {
  lax.init()

  // Add a driver that we use to control our animations
  lax.addDriver('scrollY', function () {
    return window.scrollY
  })
}

Since I plan on using lax in multiple locations within my project, I have created a separate JavaScript file to handle the functionality of each component. Thus, I added the above code snippet to the main JavaScript file that governs the entire webpage.

import lax from './lax.js';
import './component';

window.onload = function () {
  lax.init()

  // Add a driver that we use to control our animations
  lax.addDriver('scrollY', function () {
    return window.scrollY;
  });
}

However, when attempting to utilize the lax object within the component.js file, an error stating that lax is not defined is encountered. This raises the question of the correct procedure for initializing in one file and using in another when working with a third-party package like lax.js.

Answer №1

To effectively set up the lax.js package in one file and utilize it in another, it is essential to ensure that the lax object is easily accessible across your project.

Begin by creating a laxSetup.js file:

import lax from 'lax.js';

lax.init();

// Establish a driver for controlling animations
lax.addDriver('scrollY', function () {
  return window.scrollY;
});

export default lax;

In your main JavaScript file, which controls the overall functionality of the page, import and use the lax object from laxSetup.js:

import lax from './laxSetup.js';
import './component.js';

// Access and utilize the `lax` object here as necessary for global configurations

window.onload = function () {
  // Your existing code or additional logic
};

In your component.js file or any other file where you wish to make use of the lax object, import it from laxSetup.js:

import lax from './laxSetup.js';

// Now, you can utilize the `lax` object within this file
// For example:
lax.addElements('.parallax-element'); // Add elements for parallax animation
lax.setup(); // Configure animations

This approach involves setting up the lax.js package in the laxSetup.js file, allowing you to import and utilize the lax object in any file within your project. This ensures that the lax object is correctly defined and accessible throughout your codebase.
