Deploying to GitLab Pages (on each push)

deployment_to_gitlab_pages.md

(assuming project is hosted on GitLab)

1. Enable shared runners by going to "Settings" > "Runners".
2. Add .gitlab-ci.yml with the following content:

image: node:6.9.1
pages: 
  artifacts: 
    paths: 
      - build
  cache: 
    paths: 
      - .yarn-cache/
  only: 
    - master
  script: 
    - curl -o- -L https://yarnpkg.com/install.sh | bash -s -- --version 0.19.1
    - export PATH="$HOME/.yarn/bin:$PATH"
    - yarn config set cache-folder $(pwd)/.yarn-cache
    - yarn install
    - yarn build
  stage: deploy

Your website will be available at https://username.gitlab.io/projectname.
If you want the URL to look like https://username.gitlab.io, go to your project's Settings and rename your project to username.gitlab.io.
