A travel booking application built with CAP Java using master data provided by capire/xflights-java.

git clone https://github.com/capire/xtravels-java
cd xtravels-java
mvn package

The package has dependencies to other capire packages, including sap.capire/xflights-data, that can be pulled from GitHub Packages or from a local workspace setup as follows...

Reuse packages among the capire samples are published to the GitHub Packages registry. This includes Maven packages as well as NPM packages.

Authenticate to GitHub's Maven repository by adding the following to your ~/.m2/settings.xml:

<servers>
  <!-- ... -->
  <server>
    <id>github</id>
    <username>USERNAME</username>
    <password>TOKEN</password>
  </server>
</servers>

As password you're using a Personal Access Token (classic) with read:packages scope. Read more about it in Authenticating to GitHub Packages.

Run npm login once like that:

npm login --scope=@capire --registry=https://npm.pkg.github.com

When prompted for a password enter a Personal Access Token (classic) with read:packages scope. Learn more about that in Authenticating to GitHub Packages.

A successfull npm login adds entries like that to your local ~/.npmrc file, which allow you to npm install @capire packages subsequently using npm add or npm install as usual:

@capire:registry=https://npm.pkg.github.com/
//npm.pkg.github.com/:_authToken=<generated token>

Alternatively you can work with related packages in local workspace setups like so:

1. Create a workspace root for NPM, e.g. at cap/samples-java:

   mkdir -p cap/samples-java && cd cap/samples-java
   echo '{"workspaces":["*","*/apis/*"]}' > package.json

2. Add related projects:

   git clone https://github.com/capire/xtravels-java
   git clone https://github.com/capire/xflights-java
   git clone https://github.com/capire/common

3. Install NPM dependencies:

   npm install

4. Install Maven dependencies:

   cd xflights-java && mvn install

For Maven, this will share cross dependencies between projects via your local Maven repository placed at ~/.m2. For NPM, this will install all dependencies of all cloned projects, with cross dependencies between them being symlinked automatically by npm install.

To start the xtravels application, run the Application class in your preferred IDE. Alternatively, execute mvn spring-boot:run on the command line.

Click the http://localhost:8080 link in the terminal to open the app in a browser.

The dependencies to the xflights application are mocked automatically by CAP.

You can also connect the xtravels application to a locally running xflights application.

Start the xflights application first, then start the xtravels application with Spring Boot profile hybrid.
