Can you provide instructions on integrating bootstrap 5.02 using npm and webpack?

Trying to bundle my webapp with webpack, but struggling with importing the bootstrap code. I've already spent hours troubleshooting this.

Ever since setting up webpack, things haven't been working as they did before. And now, I keep encountering this error:

This is the error message I'm facing:

Here's my webpack configuration file (webpack.config.js):

const webpack = require('webpack');
const path = require('path');
const LodashModuleReplacementPlugin = require('lodash-webpack-plugin');

// Rest of the config details here...

This is the entry point in index.html:

<!doctype html>
<html lang="en">

// HTML content goes here...

</html>

Snippet of some imports in index.js:

// Import statements for various libraries go here...

And finally, here's the package.json file:

{
  // Package details listed here...
}

Environment: Chrome on Windows 11.

Answer №1

After consulting the bootstrap documentation, I was able to troubleshoot and resolve my issues. Here is a summary of what I learned:

The Bootstrap script that imports Popper into my JavaScript looks like this:

</script>
    <script type="module" src="/node_modules/bootstrap/dist/js/bootstrap.esm.min.js"></script>

To import Popper correctly, you need to use the following syntax:

import * as Popper from "@popperjs/core"

If you try to import it differently, you may encounter an error like this:

Uncaught TypeError: Failed to resolve module specifier "@popperjs/core". Relative references must start with either "/", "./", or "../".

To resolve this issue, you can utilize an import map to map arbitrary module names to their complete paths. If your targeted browsers do not support import maps, consider using the es-module-shims project. Below is an example for how it can be implemented for Bootstrap and Popper:

<script async src="https://cdn.jsdelivr.net/npm/es-module-shims@1/dist/es-module-shims.min.js" crossorigin="anonymous"></script>
<script type="importmap">
{
    "imports": {
        "@popperjs/core": "/node_modules/@popperjs/core/dist/umd/popper.min.js",
        "bootstrap": "/node_modules/bootstrap/dist/js/bootstrap.esm.min.js"
    }
}

Additionally, adding devtool: 'eval-source-map' to the webpack.config.js file at the top level of the config object helped fix any

Devtools failed to load sourcemap
errors.
