Note: This section is optional and only applies if you make changes to the application
To build the application, you need to use the gulp framework. The build handles the following tasks:
- Collect and copy various artifacts to the build area, like fonts, styles, and imgs.
- Compile all the js and jsx files into a bundle that can also execute on the browser (uses browserify).
- Minify the code and deploy it into the build area.
To start the build manually, call gulp build
To deploy to IBM Cloud, simply:
$ cf push
Note: You may notice that IBM Cloud assigns a URL to your application containing a random word. This is defined in the manifest.yml file where the random-route key set to the value of true. This ensures that multiple people deploying this application to IBM Cloud do not run into naming collisions. To specify your own route, remove the random-route line from the manifest.yml file and add a host key with the unique value you would like to use for the host name.
