Setting up a build system is not required, React with JSX can be inlined using plain old <script> tags just fine I believe. <head> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.14.6/react.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.14.6/react-dom.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.23/browser.js"></script> </head> <body> <div id="app"></div> <script type="text/babel"> // React with JSX goes here </script> </body> It it is less performant than compiled setup, of course.
