proc(ess)-that - easy extendable etl tool for nodejs written in typesript
npm install proc-thatproc(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
##### A bunch of badges
``typescript
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.
