Trouble persisting in loading PopperJS and Bootstrap through RequireJS, despite following the suggested PopperJS version

Struggling to load jquery, popperjs, and bootstrap (v4-beta) using requirejs, I'm consistently encountering this error in the console:

Uncaught Error: Bootstrap dropdown require Popper.js (https://popper.js.org)
    at bootstrap.js:6
    at bootstrap.js:6
    at bootstrap.js:6

Below is the snippet of my code in the main file:

requirejs.config({

  paths: {
    'jquery': 'lib/jquery',
    'popper': 'lib/popper',
    'bootstrap': 'lib/bootstrap'
  },

  shim: {
    'bootstrap': ['jquery', 'popper']
  }

});

requirejs(['jquery', 'popper', 'bootstrap'], function(jquery, popper, bootstrap) {});

This issue has been raised multiple times related to problems with loading popper.js and bootstrap using requirejs. Indeed, I'm utilizing the umd version specified here.

All files appear to be loading correctly on the page:

<script data-main="js/main.js" src="js/require.js"></script>
<script type="text/javascript" charset="utf-8" async="" data-requirecontext="_" data-requiremodule="main" src="js/main.js"></script>
<script type="text/javascript" charset="utf-8" async="" data-requirecontext="_" data-requiremodule="jquery" src="js/lib/jquery.js"></script>
<script type="text/javascript" charset="utf-8" async="" data-requirecontext="_" data-requiremodule="popper" src="js/lib/popper.js"></script>
<script type="text/javascript" charset="utf-8" async="" data-requirecontext="_" data-requiremodule="bootstrap" src="js/lib/bootstrap.js"></script>

The persisting error has brought me to believe that it might be related to my require configuration. Any insights on this?

Answer №1

On the flip side- "bootstrap.com/contents": Packaged JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) come with Popper, excluding jQuery.

To handle this, I integrated jQuery into my repository. Renamed the file ( "bootstrap.bundle.min.js" -> "bootstrap.min" ), established a route for bootstrap, and set up a shim for jQuery. It appears to have resolved the issue for me.

Before the official release of Bootstrap PR #22888, I managed to resolve the 

Bootstrap dropdown require Popper.js (https://popper.js.org)
issue in the following manner...

Following the approach discussed in various blog posts, the strategy involves creating a custom module that encapsulates Bootstrap. This module ensures loading and configuring popper.js correctly prior to loading bootstrap:

requirejs.config({
    "paths" : {
        "jquery"        : "https://code.jquery.com/jquery-3.2.1.slim.min",
        "popper"        : "https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.3/umd/popper.min",
        "bootstrap"     : "https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min"
        "initBootstrap" : "...custom initialization code..."
    },
    "shim" : {
        "bootstrap" : ["jquery"]
    }
});

...

define("initBootstrap", ["popper"], function(popper) {
    // set up popper as required by Bootstrap
    window.Popper = popper;
    require(["bootstrap"], function(bootstrap) {
        // allow Bootstrap to initialize itself
    });
});

It is advisable to make your code / website dependent on initBootstrap instead of bootstrap.

Alternatively, as suggested by chasepeeler, if you prefer not creating a new module, you can simply include a require statement:

require(["popper"], function(popper) {
    window.Popper = popper;
    require(["bootstrap"]);
});

Please note that this information is also available in the Bootstrap Popper Issue on GitHub.

This solution works perfectly for me;

require.config({
    
    shim: {
        'bootstrap' : ["jquery"]
      },
      paths: {
        'jquery': '../jsLibrary/jquery',
        'popper': "https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.3/umd/popper.min",
        'bootstrap': "https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min",
        'tatMusic': '../music/tatMusic'
      }
});

require(["tatMusic","popper"], function(Music,popper){
    window.Popper = popper;
    require(["bootstrap"], function(bootstrap) {
    });
});
