[node.js] How to include scripts located inside the node_modules folder?


I would use the path npm module and then do something like this:

var path = require('path');
app.use('/scripts', express.static(path.join(__dirname, 'node_modules/bootstrap/dist')));

I have a question concerning best practice for including node_modules into a HTML website. Imagine I have Bootstrap inside my node_modules folder. Now for the distribution version of the website (the live version) how would I include the Bootstrap script and CSS files located inside the node_modules folder? Does it make sense to leave Bootstrap inside that folder and do something like <script src="./node_modules/bootstrap/dist/bootstrap.min.js"></script>? Or would I have to add rules to my gulp file which then copy those files into my dist folder? Or would it be best to let gulp somehow completely remove the local bootstrap from my HTML file and replace it with the CDN version?

In my Angular 2 app, I have this in my Index.html file:

<script src="node_modules/jquery/dist/jquery.min.js"></script>
<script src="node_modules/bootstrap/dist/js/bootstrap.min.js"></script>

Here is the complete file:

<!DOCTYPE html>
    <base href="/" />
    <title>TripMate - PPS</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="styles.css">
    <link rel="stylesheet" href="node_modules/bootstrap/dist/css/bootstrap.min.css" />

    <!-- Polyfill(s) for older browsers -->
    <script src="node_modules/core-js/client/shim.min.js"></script>

    <script src="node_modules/zone.js/dist/zone.js"></script>
    <script src="node_modules/reflect-metadata/Reflect.js"></script>
    <script src="node_modules/systemjs/dist/system.src.js"></script>

    <script src="node_modules/jquery/dist/jquery.min.js"></script>
    <script src="node_modules/bootstrap/dist/js/bootstrap.min.js"></script>

    <script src="systemjs.config.js"></script>
        System.import('app').catch(function(err) { console.error(err); });


I didn't find any clean solutions (I don't want to expose the source of all my node_modules) so I just wrote a Powershell script to copy them:

$deps = "leaflet", "leaflet-search", "material-components-web"

foreach ($dep in $deps) {
    Copy-Item "node_modules/$dep/dist" "static/$dep" -Recurse

The directory 'node_modules' may not be in current directory, so you should resolve the path dynamically.

var bootstrap_dir = require.resolve('bootstrap')
app.use('/scripts', express.static(bootstrap_dir + 'dist/'));
