This step is optional and you can do it if you are interested in deploying this app to Heroku. To continue with this section, you need to have set up a Heroku account and installed the Heroku Toolbelt. Once that is done, open a new Command Prompt or Terminal inside the smart-exchange-base folder. Run the following:

$ heroku login

This will prompt you for the Heroku credentials that you have signed up with. Next, let's get our application ready for deployment. Run the following:

$ npm run build

Alternatively, run this:

$ yarn build

Either of these will run the required scripts to build the final dist folder, which will be deployed to Heroku. Once the build is completed, run the following:

$ git add -A
$ git commit -am "Cloud Natural language API Integration Commit"

Let's, push the code to Heroku. Run the following:

$ git push heroku master

If everything goes well, the code will be uploaded to Heroku and you should be able to view the application at https://smart-exchange.herokuapp.com.
