Installation NodeJS installation and setupĬonst df_a = new dataForge.

Core code is created through test driven development.

Lazy evaluation, to make the performance of immutability acceptable.

Immutable: every operation generates a new immutable data set.

The TypeScript or JavaScript code you build during exploratory coding should be easily transplantable to a webapp, server or microservice.

The library should have high performance.

Minimize the magic: everything should be understandable, the API should be orthogonal.

Intellisense in Visual Studio Code (or other IDE) should make using the API a breeze.

Simple tools should be composable to build solutions to complex data problems.

The API should be simple, easy to learn and easy to use.

The principles that drive decision making and tradeoffs:

To be able to work with massive data files (although it's not quite there yet - want to add streaming in the future).

To be able to visualize data (see Data-Forge Plot).

To be able to load, transform and save data.To combine the best aspects of Pandas and LINQ and make them available in JavaScript.This section is a short overview of the aims, principles and implementation methods for this project.

I'm happy to accept contributions to both code and documentation! Please also consider forking this repo, then add or update this document based on your own experimentation or experience with Data-Forge and then submit a pull-request. If you notice any problems please log an issue. This document is a constant work in progress.

This guide will help you dive deeper into Data-Forge and equip you with skills to build more complex data processing pipelines. Data-Forge is a open-source toolkit for data transformation and analysis in JavaScript and TypeScript.
