Deno filter

The deno filter will allow JS code to be implemented as a stage within the pipeline.

Therefore it will be possible to manipulate the block data dynamically and according to the specific rules of your business.

Configuration

Adding the following section to the daemon config file will enable the filter as part of the pipeline:

[[filters]]
type = "Deno"
main_module = "JS file Path"
use_async = true

The file should export a function that takes the event data as a parameter, for example

export async function mapEvent(event) {
    const event2 = { ...event, extraProp: "123abc" };
    return event2;
}
