React JS in HTML

I am totally new to React JS or any given server-side technology. And now, I want to learn how to develop in React JS.

Introduction

I started with React JS tutorials on official website. Now, I am trying to import React toolbox or any other third-party component into my JSX code. But, I am facing the problem of uncaught exception error: require not defined.

When I searched about it, I came to know about various build mechanisms(browserify, webpack, gulp), to which I was totally new(again). After reading about these, and seeing some examples, I was able to let my browser compile require() statements written in my .jsx files.

Problem

What I am trying to do is:

• Write a .html file.
• Start it via my server.js file.
• Add a <script> tag in it, which will inject my .jsx code into my .html file.

The examples that I have seen so far (1, 2, and some other...) load a .js file in the beginning and write their .html code in .jsx files (render() function).

Question

Is it possible to load a .html file from server.js and use .jsx from a <script> tag in that .html file? Something like this:

<html>
.
.
<body>
    <div id="container"></div>
    <script src="path_to_reactjs_file"></script>
</body>
</html>

I am sorry if this sounds like totally dumb question, but because of being totally new to this technology, I am not able to understand how I should go about it.

Any help would be appreciated.
