The Features module offers a well-known method of bundling configuration in a new module that can be installed on other sites--a feature.
The configuration management system in Drupal 8 focuses on the use case of staging configuration from one instance to another of a given site--for example, from a development instance to a testing instance or from testing to production.
Features focuses on the complimentary use case of sharing configuration among multiple sites.
If someone asks you how to make a blog on a Drupal site, you tell them that a blog is easily made with custom content types, fields, and Views – and some settings that would cover 2–3 pages of fine print.
Features module shortcuts the work with configuring settings by providing comfortable means for bundling, exporting and importing settings for many of the most used Drupal modules. Features shifts the site development paradigm from tweak here and there into enabling features.
The main advantages
- Newcomers to Drupal can quickly deploy a blog, an image gallery and a bunch of other features, while still being able to peek into the fine-print settings.
- Developers can easily reuse settings in some of the most used modules, including Views, Panels, Context, and more.
