This is another my simple and small app to let's say master React :D, this time we'll have a typical list with blogs, that contain name, description, content + tags or additional info, that you can search through them. Also you can ADD/SHOW/DELETE posts - typical CRUD with REST api, based on HEROKU api = without EDIT opt.
