## README

# proc-that

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

## Usage

```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.

## Extractors

| -------------------------- | --------------------------------- | ---------------------------------------------------- |

## Loaders

| Name                       | Description                                 | Link                                                 |
| -------------------------- | ------------------------------------------- | ---------------------------------------------------- |
| `proc-that-elastic-loader` | Load transformed objects into elasticsearch | https://github.com/smartive/proc-that-elastic-loader |

## Implement your own

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.
