# Reba

Reba is a Service Worker subset implementation for running on server side.

## Features

* Hot reconfiguration by HTTP API: Privileged Isolate to manage WorkerGroups

* Integrated cache system (?)

## Plan

* Boost Beast HTTP/1.1 Web Server

* Web Fetch API

* Websocket support

* Web Crypto API

* Basic functions: setTimeout, setInterval

## Design

Reba has two essential entities:

* WorkerGroup: A group of threads running the same script. It scales itself automatically based on the group's load.

* Router: A global instance storing the data needed to route an web request to an specific WorkerGroup

There is a special WorkerGroup created when Reba is started

* WorkerGroup Zero: It has a privileged context able to create new WorkerGroups and set routes.

The expected behavior of WorkerGroup Zero is:

* Connect to a control plane by Fetch API or Websocket

* Get the configured scripts and routes from the control plane

* Create the needed WorkerGroups

* Poll/wait for changes from the control plane
