Node destinations

Node destinations in walkerOS offer a flexible and efficient way to handle your server-side event data. Whether you're sending data to a cloud-based data warehouse like BigQuery or to a custom API, node destinations make it easy to configure, initialize, and push your events securely.

Static Configuration​

The static part of the configuration is common across all destinations and is defined in the NodeDestination.Config type. It includes properties like:

  • consent: Required consent states to process events.
  • id: A unique key for the destination.
  • init: Indicates if the destination has been initialized and is ready to work.
  • queue: Option to disable the processing of previously pushed events.

Custom Configuration​

The custom part is specific to each destination and is where you define settings that are unique to the service you are integrating with. Those destinations individual configurations are set in the custom field, and are defined in the Custom interface.

By structuring the configuration this way, walkerOS provides a flexible yet standardized way to set up any destination, making it easier to manage and extend your data pipeline.

Functions​

init​

Before pushing events to a destination, the node client checks for an available init function and calls it. This asynchronous function returns either false if an error occurs, preventing any events from being processed, or a complete destination config that will be used for pushing events.

push​

The node client calls await destination.push([{ event, mapping }], config); to send events to destinations. This function is executed after checking for proper consent settings. Events are processed in parallel, and the function supports the batching of multiple events. The mapping parameter is optional and allows for custom event configurations.
