Resources & Remarks https://wiki.optimal-systems.de/display/devkolibri/yuuvis+Momentum+-+Flex+Viewer+Service There is description for extending the viewer service mentioned to be existing in git (ask Jürgen) - however, the link is missing. Get that documentation and cast it into a tutorial article linked to this viewer service concept article! The link pointing to the "freely available" viewer components, also meant to be in git, is also inoperable or not accessible to anyone outside of team kolibri... → grab and integrate that info. Supported filetypes look nicer when in tables:
The API description lacks information... These sentences are somewhat confusing and should be checked with the PO:
Additionally provided parameters will be passed to the custom viewer. (I believe this should read: any further parameters provided will be passed to the custom viewer) Place links for further reading at the bottom (api-gateway, functional extension - client side, architecture, a still-to-be-written customization tutorial) A tutorial, describing how to integrate the viewer service into an Angular application ist missing.

Customizing
The viewer - service can be extended as described in this section.
Integration into 3rd party application
If the Viewer-Service runs in a different domain than the application that integrates it the Argus-Service has to be configured. In the file servicewatcher-sw.yml the parameter 'env' lists the parent domain has to be added as follows:
| Code Block | ||
|---|---|---|
| ||
- name: viewerservice
...
env:
ALLOWED_ORIGIN: http://myhost.com,http://myotherhost.com

Localization
The viewer-service offers a few strings with information for your users. They are part of the localization files en.json and de.json of the client.
