Package Exports
- react-codemirror2
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-codemirror2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

requiring codemirror resources
Since codemirror ships mostly unconfigured, the user is left with the responsibility for requiring any additional resources should they be necessary. This is often the case when specifying certain language modes and themes. How to import/require these assets will vary according to the specifics of your development environment. Below is a sample to include the assets necessary to specify a mode of xml
(HTML) and a material
theme.
note that the base codemirror.css file is required in all use cases
@import '~/node_modules/codemirror/lib/codemirror.css';
@import '~/node_modules/codemirror/theme/material.css';
import CodeMirror from 'react-codemirror2';
require('codemirror/mode/xml/xml');
require('codemirror/mode/javascript/javascript');
