language: node_js

git:
  # Minimize git history, but ensure to not break things:
  # - Merging multiple PR's around same time may introduce a case where it's not
  #   the last merge commit that is to be tested
  # - Aside of merge commit we need a previous commit to be able to detect a version switch
  depth: 30

cache:
  # Not relying on 'npm' shortcut, as per Travis docs it's the only 'node_modules' that it'll cache
  directories:
    - $HOME/.npm
    - node_modules

branches:
  only:
    - master # Do not build PR branches
    - /^v\d+\.\d+\.\d+$/ # Ensure to build release tags

# Ensure to install dependencies at their latest versions
install:
  # Note: `npm update` has issues which we need to workaround:
  # - There seems no way to update all project dependency groups in one run
  #   Hence different calls for prod and dev dependencies
  # - We were relying on "--depth 3", but depth setting makes optional dependencies not optional
  #   and adding "--no-optional" proven to not be a reliable workaround (worked just in some cases)
  # - npm documents --dev option for dev dependencies update, but it's only --save-dev that works
  - npm update --no-save # Updates just dependencies
  - npm update --save-dev --no-save # Updates just devDependencies
