kuco is a tool for developing custom views for the KUKA SmartProduction (KSP) IoT platform.
The developer's goal is simple: build a new custom view in an environment that is as similar as possible to the environment where the view will eventually be deployed. We want all out-of-the-box features and environment-specific configurations and datasets to be available during development of a custom view.
To achieve this, kuco starts a local webserver and delegates all backend calls to an existing instance of KSP (e.g. production.onkuka.com) while simultaneously intelligently splicing in any custom views being developed locally.
The first step is to create a working directory for our custom view project:
$ mkdir my-first-kuco-project $ cd my-first-kuco-project
Then, we need to install kuco locally:
$ npm install -g kuco
Create a simple asset view:
$ kuco view:addAssetView hello-world
A quick directory listing shows us that kuco has initialised our working directory:
$ ls -la drwxr-xr-x 4 someuser staff 136 Aug 16 14:30 . drwxr-xr-x+ 93 someuser staff 3162 Aug 16 14:30 .. -rw-r--r-- 1 someuser staff 408 Aug 16 14:30 config.json drwxr-xr-x 3 someuser staff 102 Aug 16 14:30 kuco
config.json contains all metadata on the views in this module. While this file can be edited manually, this is usually a bad idea and should be left to kuco.
kuco contains the resources that make up our custom view(s). Each view resides in the directory
kuco/views/VIEWNAME, in our case for example
Like in the production environment, KSP needs to be told which custom view is to be displayed under which circumstances.
Asset views can be associated with an asset type and/or an asset's serial number:
$ kuco view:associate hello-world assetType type42
This will result in all assets with the asset type
type42 being shown in our new custom view rather than the KSP system default view.
Now that we have a custom view and have configured when it is to be displayed in place of the KSP default view, we can start up the local webserver:
$ kuco serve
During start-up, you will be prompted for various things:
And just like that, you can check out your custom view by navigating to a suitable asset:
For more information on the available features in kuco, use the command:
$ kuco -h
Not all upgrades of kuco are 100% backwards compatible, and will require manual migration effort.
Release 0.6.0 of kuco introduced two breaking changes to existing kuco modules:
All affected modules will have to be manually migrated:
