I'm trying to implement an i18n react library by following this tutorial I got to the step
- Alright, now when we run npm run build we should see build/locales/data.json which combines all of our JSON files into one.
And since then I can not get npm run build to work. I fix one error and another one appears. I am guessing that it's babel/webpack problems, since I have no experience with them and the tutorial had some older babel syntax errors that I managed with.
Here is my package.json
