I am unable to access my JavaScript class in Laravel Mix

Within my Laravel project, I have developed a custom form validation class. However, after running npm run dev, I am unable to access this class.

Files:

small-form-validation.js

class SmallFormValidator {
    errMsgs = {
        required: 'This field is required!',
        string: 'Not valid string.',
        ...

my app.js

require('./bootstrap');
require('./myvendor/small-form-validator');

Upon compilation, I discovered that the source code from the SmallFormValidator class was present in the newly created app.js file within the public folder. It appears as though it compiled correctly.

In my blade template, I use the mixing helper to load the app.js file. However, within the JavaScript code inside the blade template, I encounter issues when trying to create an instance of SmallFormValidation (var sfv = new SmallFormValidation()).

I suspect that these problems stem from either:

My lack of familiarity with module exports and related concepts
Potential scope-related issues

If anyone has insights on how to resolve this issue, I would greatly appreciate the assistance.

Answer №1

If you're looking for a quick solution, consider assigning it to the global/window object. In your small-form-validation.js file, insert

window.SmallFormValidator = SmallFormValidator

to make it accessible globally.

Alternatively, a more efficient approach would be to use module exports and imports.

Illustration

// Place this at the end of the file
export default SmallFormValidator

// Alternatively, include it while declaring the class:
export default class SmallFormValidator {
  // class content
}

To utilize it in another file, import it as shown below:

// At the beginning of your file
import SmallFormValidator from '../path/to/small-form-validation'

// You can then use it within this file
const smallFormValidator = new SmallFormValidator()
smallFormValidator.jeKaleZus() // or any other method you prefer

I hope this explanation proves useful for you!
