Uses your npmjs and GitHub tokens to make travis trigger npm publish for every* master build. Requires some standards on commit messages though...

-* every release that has fix and feat commits.

travis-watch exists with a non-zero exit code if the CI fails. So if I don't misunderstand you, you can just do travis-watch && npx semantic-release to achieve this.
