Caterpillar

Given the recent interest in progressive web apps, this experimental project investigates whether it is feasible to automatically port Chrome Apps to web sites that run offline in Chrome and other modern browsers.

Installation

Extract the code into a folder. Install dependencies with pip and npm:

$ pip install -r requirements.txt && npm install

Usage

./caterpillar.py config -i config.json
./caterpillar.py convert -c config.json my-chrome-app/ my-web-app/

This will convert an unpackaged Chrome App my-chrome-app/ into a progressive web app my-web-app/ and generate a conversion report inside a subdirectory of my-web-app/ (depending on the configuration options you set).

For more detailed documentation, see the manual.
