Error encountered in Bootstrap 5: Popper__namespace.createPopper function is not defined

Currently using Django to host web pages.

  • Focus is on enabling offline access by downloading all necessary resources to ensure webpage functionality, like Bootstrap 5.

  • Attempting to utilize the dropdown menu feature in Bootstrap:

    Dropdowns depend on Popper library for dynamic positioning and viewport detection. Popper should be included before Bootstrap’s JavaScript or using bootstrap.bundle.min.js / bootstrap.bundle.js. Navbars do not require dynamic positioning using Popper.

  • Multiple <script> tags added to troubleshoot the issue, unsure if it's the correct approach.

Seeking recommendations for next steps.

{% load static %}

-- code snippet --

Further research indicates that a newer version of Popper might be causing the problem. Further investigation is needed.

Resolution

Tested a code snippet from Bootstrap's download page and it worked. Reviewed all bootstrap resources and identified an issue with the bootstrap.js file.

Downloaded the latest distribution from npm and replaced the Popper CDN with the npm version. Ensure to only use .min. files for proper functionality.

Answer №1

Encountering the error message (

TypeError: i.createPopper is not a function
) whenever the popovers should be displayed has been a consistent issue for me. In the past, I had to resort to using Separate Popper and Bootstrap JS (Option 2) to resolve conflicts with other scripts. However, in my current project utilizing Bootstrap 5.1.1, this workaround is no longer needed.

Simply including the Bootstrap bundle with popper - as suggested by @Kevin in the comment above - has successfully resolved the problem for me. Additionally, the previous conflicts no longer appear to be causing any issues. All components like popovers, tooltips, modals, sidebars, etc., are now functioning as expected:

</body>

Answer №2

Instead of including bootstrap.min.js, I inadvertently included bootstrap.bundle.min.js

Answer №3

Ensure that for your angular project, you include the following script in your package.json file: 

 "scripts": [ "./node_modules/bootstrap/dist/js/bootstrap.bundle.min.js" ]
.

Answer №4

The reason for this issue is that Bootstrap 5+ relies on popper js for dropdown functionality. To resolve this, you need to include popper.js or popper.min.js in your script sources prior to bootstrap.min.js. Alternatively, you can utilize bootstrap.bundle.js (or bootsrap.bundle.min.js).

Instead of just including:

<script src="[...YOUR_JS_CDN...]/bootstrap.min.js" />

Add popper js before bootstrap:

<script src="[...YOUR_JS_CDN...]/popper.min.js" />
<script src="[...YOUR_JS_CDN...]/bootstrap.min.js" />

Or opt for bootstrap.bundle:

<script src="[...YOUR_JS_CDN...]/bootstrap.bundle.min.js" />

To simplify, in your scenario, remove the unnecessary redeclarations of bootstrap js:

<script src="{% static 'Pages/Bootstrap/bootstrap-5.0.2-dist/js/bootstrap.bundle.js' %}"></script>

Answer №5

Encountering the same issue in my ANGULAR 13 project led me to make the following modifications to resolve it:

I adjusted the code within the angular.json file under the build >> options >> scripts section.

            "scripts": [
              "node_modules/jquery/dist/jquery.min.js",
              
              "src/assets/js/popper.min.js",
              "src/assets/js/calender.js",
              "src/assets/js/jquery.easing.min.js",

              "node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"
            ]

Additionally, I specified the versions of BOOTSTRAP, JQUERY, and POPPER JS in the package.json file like so:

"bootstrap": "^5.1.3",
"jquery": "^3.6.0",
"popper.js": "^1.16.1",

Answer №6

In the context of the Angular project, it is necessary to define the component in which the navbar or function is being accessed. Grab the @popperjs/core library by importing { createPopper }.

Answer №7

Currently, I have successfully integrated Bootstrap's icons into my project by configuring my angular.json file as follows:

"styles"[
    "node_modules/bootstrap/dist/css/bootstrap.min.css",
    "node_modules/bootstrap-icons/font/bootstrap-cons.css"
],
"scripts": [
    "node_modules/bootstrap/dist/js/bootstrap.bundle.js"
]

Just with these three imports, I was able to resolve the issue I was facing. I hope this configuration proves helpful to others as well.

I followed the Bootstrap documentation, which states:

Dropdowns rely on Popper, a third-party library, for dynamic positioning and viewport detection. Ensure that popper.min.js is included before Bootstrap’s JavaScript, or use bootstrap.bundle.min.js / bootstrap.bundle.js, which already includes Popper. However, Popper is not utilized for positioning dropdowns in navbars since dynamic positioning is not necessary for that.

https://getbootstrap.com/docs/5.3/components/dropdowns/

Answer №8

According to the official Bootstrap documentation:

It is required to include popper.min.js prior to bootstrap.js or utilize bootstrap.bundle.min.js / bootstrap.bundle.js

Following these steps will make it functional.

Answer №9

Made progress by relocating the popper.js file to src/assets/js/popper.min.js within the Angular 13 framework

Answer №10

Dealing with a similar issue, I discovered that the culprit was the incorrect order of JavaScript insertions. Make sure to load popper.js before bootstrap.js as advised on the Bootstrap documentation website. Following this sequence resolved the problem in my situation.

Answer №11

This issue arises when popper.js is not loaded alongside bootstrap.

Popper.js is essential for the functionality of the bootstrap dropdown menu. To enable the bootstrap menu, popper.js must be utilized.

You can integrate this bootstrap starter file into any project, whether it's built on Django or any other framework.

  </body>
</html>

Alternatively, you can include popper.js and bootstrap.js before the closing body tag, ensuring that popper.js is loaded before bootstrap.

Answer №12

When setting up my Vue 3 and Nuxt-bridge application, I included the following code snippet in the nuxt.config.js file:

script: [
      {
        src: "https://cdn.jsdelivr.net/npm/@popperjs/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2f4c405d4a6f1d0116011d">[email protected]</a>/dist/umd/popper.min.js",
        type: "text/javascript"
      },
      {
        src: "https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2f4d40405b5c5b5d4e5f6f1a011e011e">[email protected]</a>/dist/js/bootstrap.bundle.min.js",

        crossorigin:"anonymous"

      }
]

I also double-checked to ensure that there were no conflicting versions of Bootstrap or jQuery in my package.json file.

Answer №13

Dealing with a similar problem involving popper.js, I recently discovered that switching from my CDN to the Bootstrap JS bundle helped resolve the issue.

Answer №14

If you have not yet installed Bootstrap, start by running the command npm i bootstrap. Once Bootstrap is installed, follow these steps:

Go to your Angular.json file and insert the following code:

"scripts":["node_modules/bootstrap/dist/js/bootstrap.min.js",
"node_modules/bootstrap/dist/js/bootstrap.bundle.js"]

Be sure to include bootstrap.min.js before bootstrap.bundle.js.

Answer №15

To resolve the issue in my Django base template, I took the following steps:

1 - I uploaded a popper.min.js file to the static folder under js/popper.min.js

2 - I referenced the file in my base.html template as shown below:

<script type="text/javascript" src="{% static 'js/popper.min.js' %}"></script>
<script src="{% static 'css/bootstrap/dist/js/bootstrap.min.js' %}"></script>

Answer №16

In the project I am currently working on, I have decided to only include the bundle version of the ".js" file. This decision was made because I am only using two files from Bootstrap version 5.3.

<link href="~/lib/bootstrap/bootstrap.min.css" rel="stylesheet" />
<script src="~/lib/bootstrap/bootstrap.bundle.min.js"></script>
