I am trying to deploy a react app at username.gihub.io
There are 2 main issues
username.github.io
(cannot be changed )Has anyone deployed a react app in this url. If so, tell me how did you do it?
(Other than drag and drop build folder to master )
Easiest way to deploy using GitHub now is by the new deploy from docs folder found here at the end of the page.
You should be able to tweak your app to run build into the docs folder, way less headache than trying to get regular github-pages working imo.
For fast sanity checking you can also drag your app into /docs
