In the terms of WebStorm, content is a collection of files with which you are currently working, possibly organized in a hierarchy of subfolders. The folder which is the highest in this hierarchy is called content root folder or content root (shown as ) for short. A project has at least one content root folder, by default it is the project folder itself.
Having several content roots enables you to work with files from several directories that do not have a common immediate parent. This is helpful when you use some static contents, for example, icons. You can just save them all in a folder and then specify this folder as an extra content root in several projects.
Types of content roots
By default, all the files in a content root folder are involved in indexing, searching, parsing, code completion, etc. To change this status, folders within a content root can be assigned to the following categories:
- A Tests folder contains source files related to unit testing. These folders are marked with the icon .
- Resource Root. By assigning a folder to this category you tell WebStorm that files in it and in its subfolders can be referenced relative to this folder instead of specifying full paths to them. These folders are marked with the icon .
- An Excluded folder contains files and folders ignored by WebStorm when indexing, searching, parsing, watching, etc. These folders are marked with the icon. Usually, one would like to exclude temporary folders, logs, and other project output. Excluding unnecessary paths is a good way to significantly improve performance.
