Select 2 4.x.x Node+Jasmine testing example

This is a toy project representing a real production project that we had a problem with.

The project worked fine under Select2 version 3.

We need to upgrade select2 for several reasons.

Under select2 version 4, everything works just fine, EXCEPT, we could not get Jasmine (unit testing) to work. At all.

Turned out we had to feed it like this:

require('select2/dist/js/select2.full.js')(dom, $);

EVERYTHING BELOW THIS LINE IS OLD:

Examining the problem for yourself

1. yarn install
2. Run bin/jasmine
3. Observe the failure

node_modules/select2/dist/js/select2.full.js:6548
    if ( $.event.fixHooks ) {
                 ^

TypeError: Cannot read properties of undefined (reading 'fixHooks')

Node.js v17.8.0

You can verify that select2 v3.x.x is OK:

1. downgrade package.json to "select2": "^3.5.2-browserify" and yarn install
2. open bin/jasmine and uncomment this line // require('select2/select2.js'); // works fine with select2 version 3.x and comment the other requires pertaining to select2
3. Run bin/jasmine
4. Observe that it works

Most likely cause

It seems that select2's loading mechanism was changed between v3 and v4. We don't know how to resolve it and are totally stuck.
