Documentation

This library is available in three different builds: minimal, core and full. Each larger build contains all functionalities from the smaller ones.

The core build is the one that you get when you require('openchemlib'). It contains all functionalities that can be used in Node.js.

The minimal (require('openchemlib/minimal')) build is a smaller one (~ half the size of core) that is meant to be used in a browser application if bundle size matters and prediction functionalities are not needed.

The full build (require('openchemlib/full')) build is the largest build. It contains a structure viewer and a structure editor for browser applications.
