Hi, how can I use this with travis-ci to deploy and create my release notes in GitHub?

Hi @felixjb, I use it this way:

Gemfile

source "https://rubygems.org"
gem 'github_changelog_generator'

travis.yml

      before_script:
        - bundle install
        - bundle exec github_changelog_generator --max-issues 0 -t ${GITHUB_API_TOKEN} --between-tags ${TRAVIS_TAG}
      script: bundle exec github_release.rb -s ${GITHUB_API_TOKEN} -r ${TRAVIS_REPO_SLUG} -c CHANGELOG.md -t ${TRAVIS_TAG}

Is there a way to use it entirely on travis.yml? Because my project is in TypeScript

I am not sure what you are asking. The Gemfile is needed to install github_changelog_generator that generates CHANGELOG.md with release notes from commits between TRAVIS_TAG.

If you already have your changelog file, you can just call the script directly by replacing those parameters..
