proc(ess)-that - easy extendable etl tool for nodejs written in typescript.
Basically instantiate the Etl
class and add extractors (which pull data from a datasource), transformers (which process the extracted data) and loaders (they load the results into a sink).
A basic, hypothetic example could be: "Load data from a JSON array, snake_case all properties and store those objects into a mongoDB."
The package is written in typescript
but can be used in plain javascript as well
import { Etl } from "proc-that";
new Etl()
.addExtractor(/* class that implements Extractor */)
.addTransformer(/* class that implements Transformer */)
.addLoader(/* class that implements Loader */)
.start()
.subscribe(progress, error, success);
After all objects are extracted, transformed and loaded, the .start()
observable completes and the process is finished.
Below is a list if extractors and loaders that are already implemented. Feel free to implement your own extractor / transformer / loader and contribute it to this list with a PR.

To ease up implementing your own extractors / transformers or loaders, just create a new repository and install proc-that
as a dev-dependency. This package contains the needed definition files for the interfaces you need to create the extensions.
