# Architecture

The Reactium Ecosystem is meant to provide a developer the means to develop any sort of application rapidly and at scale.

### The Approach

We set out to create a modular and headless JavaScript architecture where parts can be swapped out or omitted per need. 

That being said, there's a fair bit of configuration and convention that must be adhered to in order to achieve certain outcomes. 

### Tech Stack 

Our primary tech stack includes the following: 

| Tech                                                                       | Usage                                                                           |
