In ES6 you are allowed to export names using the export function, or for default you can export anything.
The require format goes like this:
let config = require('config')
And it takes the default export of config file.
In your case, you should do:
export default config[env]
If you want to use the export, you would do something like:
let Environment = config[env];
export {Environment}
The difference would be:
import EnvirmentNameWhatever from "./config"
to
import {Environment} from "./config"
- Note – when default exporting, you can use whatever name you like, while when just exporting, you have to use the exported name.
