Heroku Environmental Variables

By -

Heroku provide a nice solution for manage the variables within the cross environments.

You can define the production variables within heroku and hide the details in .env files or keep the test data on .env files.

This was discussed in may treads and I was able to find the best approach integrate it with react-starter-app. https://www.npmjs.com/package/quill-image-resize-module If you use the following code, import Quill from ' quill ' ; import { ImageResize } from ' quill-image-resize-module ' ; Quill . register ( ' modules/imageResize ' , ImageResize); const quill = new Quill (editor, { // ... modules : { // ... imageResize : { // See optional "config" below } } }); The following error is common.
