-# cloud-cap-samples
+# Welcome to cap/samples
 
-This is a monorepository for sample projects on [SAP Cloud Application Programming Model](https://cap.cloud.sap).
+Find here a collection of samples for the [SAP Cloud Application Programming Model](https://cap.cloud.sap) organized in a simplistic [monorepo setup](samples.md#all-in-one-monorepo). → See [**Overview** of contained samples](samples.md)
 
-## Description
-
-This repository provides a list of samples and reusable packages created based on SAP Cloud Application Programming Model.
-The SAP Cloud Application Programming Model enables you to quickly create business applications by allowing you to focus on your domain logic. It offers a consistent end-to-end programming model that includes languages, libraries and APIs tailored for full-stack development on SAP Cloud Platform.
-
-The samples provided can be run in a local setup on SQLite Database.
+![](https://github.com/SAP-samples/cloud-cap-samples/workflows/CI/badge.svg)
+<!--[![REUSE status](https://api.reuse.software/badge/github.com/SAP-samples/cloud-cap-samples)](https://api.reuse.software/info/github.com/SAP-samples/cloud-cap-samples)-->
 
 
-## Requirements
-* [Node.js](https://nodejs.org/en/) v8 or higher
-* [Git](https://git-scm.com)
-* [SQLite DB](https://www.sqlite.org/download.html) (Windows only; pre-installed on Mac/Linux)
+### Preliminaries
 
-#### Optional (if you want to import the code into an editor)
-* [VS Code](https://code.visualstudio.com)
-* [Add CDS extension to VS](https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/be944d6d51f343f6b3f53c29c44ff00a.html)
+1. Install [**@sap/cds-dk**](https://cap.cloud.sap/docs/get-started/) globally:
 
-## Download and Installation
+   ```sh
+   npm i -g @sap/cds-dk
+   ```
+
+2. _Optional:_ [Use Visual Studio Code](https://cap.cloud.sap/docs/get-started/tools#vscode)
+
+### Download
+
+If you have [Git](https://git-scm.com/downloads) installed, clone this repo as shown below, otherwise [download as ZIP file](archive/master.zip).
 
-#### Install `cds` development kit
 ```sh
-# sets the registry for `@sap` packages
-npm set @sap:registry=https://npm.sap.com
-
-npm install -g @sap/cds-dk
-cds  #> test-run it
+git clone https://github.com/sap-samples/cloud-cap-samples samples
+cd samples
 ```
-Got issues?  Check out the [documentation](https://cap.cloud.sap/docs/get-started/).
 
-#### Clone and build the application
-`git clone https://github.com/SAP-samples/cloud-cap-samples samples && cd samples && npm i`
+### Setup
 
-#### Run the samples
+In the samples folder run:
 
-With that you're ready to run the samples, e.g. start the [_bookshop_](./packages/bookshop) sample as follows:
+```sh
+npm install
+```
 
-`npm run bookshop`
+### Run
 
-## Test
+With that you're ready to run the samples, for example:
 
-For example, try these links in your browser:
-- <http://localhost:4004> to test with generic index page.
-- <http://localhost:4004/fiori.html> to test with Fiori sandbox.
+```sh
+cds watch bookshop
+```
+
+After that open this link in your browser: [http://localhost:4004](http://localhost:4004)
+
+When asked to log in, type `alice` as user and leave the password field blank, which is the [default user](https://cap.cloud.sap/docs/node.js/authentication#mocked).
+
+### Testing
+
+Run the provided tests with [_jest_](http://jestjs.io) or [_mocha_](http://mochajs.org), for example:
+
+```sh
+npx jest
+```
+> While mocha is a bit smaller and faster, jest runs tests in parallel and isolation, which allows to run all tests.
 
 
-## Debug
+### Serve `npm`
 
-For example, in [VS Code](https://code.visualstudio.com) switch to _Debug_ view and launch one of the prepared _cds run_ launch configurations.
+We've included a simple npm registry mock, which allows you to do an `npm install @capire/<package>` locally. Use it as follows:
+
+1. Start the @capire registry:
+```sh
+npm run registry
+```
+> While running this will have `@capire:registry=http://localhost:4444` set with npmrc.
+
+2. Install one of the @capire packages wherever you like, for example:
+
+```sh
+npm add @capire/common @capire/bookshop
+```

An Autobiography), erstmals erschienen im Jahr 1847 unter dem Pseudonym Currer Bell, ist der erste veröffentlichte Roman der britischen Autorin Charlotte Brontë und ein Klassiker der viktorianischen Romanliteratur des 19.

Der Roman erzählt in Form einer Ich-Erzählung die Lebensgeschichte von Jane Eyre (ausgesprochen /ˌdʒeɪn ˈɛə/), die nach einer schweren Kindheit eine Stelle als Gouvernante annimmt und sich in ihren Arbeitgeber verliebt, jedoch immer wieder um ihre Freiheit und Selbstbestimmung kämpfen muss. Als klein, dünn, blass, stets schlicht dunkel gekleidet und mit strengem Mittelscheitel beschrieben, gilt die Heldin des Romans Jane Eyre nicht zuletzt aufgrund der Kino- und Fernsehversionen der melodramatischen Romanvorlage als die bekannteste englische Gouvernante der Literaturgeschichte

+# Bookshop Getting Started Sample
+
+This stand-alone sample introduces the essential tasks in the development of CAP-based services as also covered in the [Getting Started guide in capire](https://cap.cloud.sap/docs/get-started/in-a-nutshell).
+
+## Hypothetical Use Cases
+
+1. Build a service that allows to browse _Books_ and _Authors_.
+2. Books have assigned _Genres_, which are organized hierarchically.
+3. All users may browse books without login.
+4. All entries are maintained by Administrators.
+5. End users may order books (the actual order mgmt being out of scope).
+
+## Running the Sample
+
+```sh
+npm run watch
+```
+
+## Content & Best Practices
