{
  "presets": ["es2015", "stage-0", "react"],
  "env": {
    "development": {
      "plugins": [
        ["transform-object-rest-spread"],
 ["transform-react-display-name"],

You probably won't need to do this often (if ever at all) but just in case, here is how to delete a tag from a remote Git repository.

If you have a tag named '12345' then you would just do this:

git tag -d 12345
git push origin :refs/tags/12345
That will remove '12345' from the remote repository.
