Tips for using RequireJS to load front-end NPM/Yarn packages

In my front end SPA built with Knockout, I am facing the challenge of its growing size. To resolve this issue, I plan on splitting it into multiple files and restructuring my folder as follows:

node_modules
|- knockout
\- requirejs
components
|- MyFutureViewModel.js
\- etc.
index.html
app.js

The structure of index.html is like this:

<!DOCTYPE html>
<html>
  <head>
    <title>MyApp</title>
    <meta charset="utf-8">
    <script type="text/javascript" data-main="app.js" src="./node_modules/requirejs/require.js"></script>
  </head>
  <body>
    <p>Enter your name: <input data-bind="value: name" /></p>
    <p>You entered: <span data-bind="text: name"></span>.</p>
  </body>
</html>

This is a snippet from my app.js file:

requirejs.config({
  //Ensure correct loading of node modules relative to main JS file.
  nodeRequire: require
});

require(['knockout'], function(ko) {
  var viewModel = function() {
    name: ko.observable('name')
  };
  ko.applyBindings(viewModel);
});

Despite the setup, requirejs is unable to locate knockout. Is there a missing configuration or step?

Answer №1

In order to update your RequireJS configuration, you need to make the following adjustments:


requirejs.config({
    baseUrl: "assets/",
    paths: {
         // if knockout is located in assets/knockout/knockout.js
         // if not, adjust the path relative to the 'assets' directory 
         // without specifying the .js extension
        'knockout': 'knockout/knockout',
    }
});
