Error Alert: Vue is not recognized in Browserify environment

My venture into front-end development has just begun and I am experimenting with Vue.js along with Browserify. The main 'app.js' file includes:

window.$ = window.jQuery = require('jquery');
require('bootstrap');
var moment = require('moment');
var fullCalendar = require('./vendor/fullcalendar.min.js');
var datetimepicker = require('./vendor/bootstrap-datetimepicker.min.js');
var select2 = require('./vendor/select2.min.js');
var VueResource = require('vue-resource');
var Vue = require('vue');
require('./videos/show.js');
require('./home.js');
require('./search.js');

Vue.use(VueResource);

new Vue({
    el: '#search',

    data: {
        message: 'Hello World!'
    },

});

...

Although everything works as expected, I encountered an issue when attempting to create a new Vue instance in another file (such as search.js), resulting in a 'Uncaught reference error: Vue is not defined'. I also found that importing jQuery in a different manner did not work:

var $, jQuery = require('jquery');

I realize there may be some basic concepts that I am overlooking, so any assistance would be greatly appreciated!

Answer №1

Your issue seems to stem from the fundamentals of module usage. Typically, a module is meant to export specific functionality or attributes which can then be utilized after requiring the module. For instance, let's say I want to insert a hidden token into a form on certain pages. The process would look something like this:

InsertHiddenToken.js

module.exports = function(form) {
  // implementation to add hidden input to the provided form
}

Then, in another part of your code where you have a form requiring the secret token, you would require it as follows:

MainForm.js

var insertHiddenToken = require('./InsertHiddenToken');

...
// code snippet creating a form
insertHiddenToken(mainForm);
...

Naturally, there will be a point where actual execution takes place, typically within your main module or page that requires all necessary modules and triggers the appropriate functions without exporting anything explicitly. This approach makes sense for readability and organization. However, the majority of modules should not adhere to this pattern.

Whenever you need certain functionality, it's best practice to create a corresponding module and require it wherever necessary. Each module should handle its dependencies internally, rather than relying on global scope (with jQuery being a possible exception).
