Implement npm within an Asp .Net Core 6 MVC project to manage dependencies, rather than relying on CDNs

Seeking guidance on integrating npm within a .Net Core 6 MVC project. I have included the file webpack.config.js with the following configuration:


module.exports = {
    entry: [
        "babel-polyfill",
        "./src/main"
    ],
    output: {
        publicPath: "/js/",
        path: path.join(__dirname, "/wwwroot/js/"),
        filename: "main.build.js"
    }
};

In addition to the automatically generated files package.json and package-lock.json after running npm init and installing libraries,
I have referenced the file main.build.js in my HTML as follows:

<script src="~/js/main.build.js" asp-append-version="true"></script>

In my program.cs, I have added:
app.UseDefaultFiles();
app.UseStaticFiles();

Challenges I'm encountering include:

  • Receiving an error require is not defined when using let Web3 = require('web3'); in main.build.js
  • Getting the error
    Cannot use import statement outside a module
    when converting the require statement to
    import Web3 from "web3"
  • Adding type="module" to
    <script src="~/js/main.build.js" type="module" asp-append-version="true"></script>
    results in
    Failed to resolve module specifier "web3". Relative references must start with either "/", "./", or "../"
  • Attempting to specify the relative path starting with ../../node_modules/ like
    import Web3 from "../../node_modules/web3";
    leads to
    GET https://localhost:7101/node_modules/web3 net::ERR_ABORTED 404
  • I intend to utilize npm packages in multiple js files, not just within main.build.js. What further modifications are needed in webpack.config.js?

Any pointers, tutorials, assistance, or recommendations would be greatly appreciated. A sample GitHub repository demonstrating npm usage in a .Net Core 6 MVC project would be beneficial.
