It is always a good practice (but not necessary) to prepare a seperate production profile to remove modules that are not needed in the production (delivery) environment. The profile will also calls custom module that are built specially for production environment. An idea of what the custom module will contains:
- Minified css and javascript
- Google Analytics (for production)
Below shows a list of IBM default modules that we will usually remove from our production profile:
| Module | Description |
|---|---|
| getting_started_module | The getting started module is a pre-defined module that you can use as starting place to quickly inject your own resources into the current theme. |
| wp_toolbar_host_view | Module that groups all theme modules that are needed to make a page interoperable with the site toolbar. Add this module to the theme profile of your page if you want to edit the page by using the site toolbar. This module contains all contributions that are needed for view mode. This module must be added to the non-deferred section of the theme profile. |
| wp_portlet_css | Earlier portlet CSS support. |
| wp_client_ext | Contains advanced utilities like Promises, IO, DOM helpers, events, and the deferred module loading code. |

In case you are wondering how much does this exercise really save. It only managed to save 2 http requests and 54KB. The difference isn’t significant but we did it anyway for all of our clients.
