DISCLAIMER: This bundle needs a specific ALMA configuration to work. Please contact info@digital-blueprint.org for more information.

This Symfony 4.4 bundle provides API endpoints for

  • assigning a call number to a book
  • borrowing a book from the sublibrary
  • returning a book to the sublibrary
  • extending a loan period for a book
  • showing sublibrary's book list
  • showing sublibrary's current loans
  • showing sublibrary's current book orders

for the API-Gateway.

There is a corresponding frontend application that uses this API at Sublibrary Frontend Application.


  • API Gateway with openAPI/Swagger
  • Alma backend access with special configuration (for analytics)

Bundle installation

You can install the bundle directly from packagist.org.

composer require dbp/relay-sublibrary-bundle

Integration into the API Server

  • Add the necessary bundles to your config/bundles.php:
Dbp\Relay\SublibraryBundle\DbpRelaySublibraryBundle::class => ['all' => true],
Dbp\Relay\CoreBundle\DbpRelayCoreBundle::class => ['all' => true],
  • Run composer install to clear caches


The bundle has configuration values that you can specify in your app, either by hardcoding it, or by referencing an environment variable.

For this create config/packages/dbp_relay_sublibrary.yaml in the app with the following content:

  api_url: '%env(ALMA_API_URL)%'
  api_key: '%env(ALMA_API_KEY)%'
  analytics_api_key: '%env(ALMA_ANALYTICS_API_KEY)%'
  readonly: '%env(bool:ALMA_READONLY)%'

Your .env file should then contain the following environment variables you need to configure the bundle:

###> dbp/relay-sublibrary-bundle ###
###< dbp/relay-sublibrary-bundle ###

If you were using the DBP API Server Template as template for your Symfony application, then the configuration files should have already been generated for you.
