Folder Structure

Before starting our project it makes sense to understand the extension folder we have extended:

As you have noticed the folder structure consists of the following directories:

.
├── CAP Directory Structure
├── db
│ ├── This folder is where you put your extensions of entities and UIs (Fiori Elements). (link to fiori elements?)
│ └── (see db inside node\_modules for reference of models which can beextended)
├── node_modules
│ └── Expanding this folder you will notice an embedded structure:
├── This is the reference models and services exposed that you are able to extend.
│ └── base
│ └── _i18n : This contain the i18n of the provider.
│ ├── Open the file and see the i18n keys and values.
│ ├── db : The entities available to extend./
│ │ ├── (The following is an example of the exposed list)
│ │ ├── Please refer to released documentation to understand in detail the referenced
│ │ └── entities.(get link)

Note: There is also a node_modules directory inside of _base, this can be ignored.

Avoid running npm install otherwise it will delete the _base folder.
