title: Webpack 2 and react production
body: <p>Is it possible when I build my project <code>npm run build</code> to generate config files where we can change a few variable value on the fly without rebuilding the whole project every time I change a value? </p>
  
  <p>The config file need to be in <code>.json</code> or in <code>.js</code> and will contain variables like : updateDelay, pageNumber, path, graphQlUri... Variables that are used in the projects and can be changed by the user. </p>
  
  <p>If it's possible how I'm doing it?</p>
  
  <p>Thanks</p>
