This directory contains the source code distribution of Vitrivr NG (stands for either 'Angular' or 'Next Generation'). It was created using Angular

Vitrivr NG is a web-based user interface developed to be used with the latest version if Cineast. It allows the user to browse in and retrieve from mixed multimedia collections.

For setup information, consult our Wiki

We follow a zero-config approach, where everything has reasonable defaults. There is a src/config.template.json file which you can copy to src/config.json and modify if you have custom needs. The default values are in the code. Information about the configuration can be found in the slightly outdated wiki.

In a setup where the backend aka API is available via a secure connection, the following adjustments make vitrivr-ng respect those:

api: {
  "http_secure": true,
  "ws_secure":true
}

It might be necessary to also adjust host and port values in api config.

From the project folder, run ng serve to start a development server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files. If you wish to prevent automatic reloading, run ng serve --live-reload=false

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.

Note: this section is only relevant if you've made changes to the Cineast API and need to udpate the OpenAPI bindings.

In order to update / generate the OpenApi stubs and data model, run the following command while Cineast is running and having the OpenApi serving enabled (config option "enableRestLiveDoc": "true" )

npm run gen-local-api

This is an alias for the full-fledged command:

openapi-generator-cli generate -g typescript-angular -i http://localhost:4567/openapi-specs -o openapi/cineast --skip-validate-spec --additional-properties npmName=@cineast-openapi/api,snapshot=true,ngVersion=13.0.0

The assumption for this snippet is, that the Cineast is running on localhost using port 4567. Adjust according to your needs.

This will break ng serve as it will generate imports for a Set class which does not exist. Simply remove all such imports which cause errors, the code will work fine.

Since Vitrivr NG might be used in a competition context, we rely on DRES.

To update (and / or initially fetch) the DRES client library, use this command:

npm run gen-dres-client

To get more help on the Angular CLI use ng help or go check out the Angular CLI README.
