Problems with UMD Build and Webpack

[codeart1st]

Hey is it possible to generate the js bundle without all the dependencies? The js bundle from react-openlayers ist huge (1.42MB) and includes react+openlayers itself.

If you try things like this with proj4 in a plain es6/jsx project

import { Controls, Layers, Map, control, layer } from 'react-openlayers';

import React from 'react';
import ol from 'openlayers';
import proj4 from 'proj4';

ol.proj.setProj4(proj4);
proj4.defs(EPSG25833, '+proj=utm +zone=33 +ellps=GRS80 +units=m +no_defs');

it's not possible to get it working, because there are two instances of ol defined in the final bundle. Currently I use my own build from your npm package with webpack-node-externals activated. Would be nice if a smaller bundle could be the default - and then setting the peer dependencies (ol, react, ...) in npm package.json itself.

Thanks I agree with you
If possible can you make a PR, Pull Request, before I make time for it?
