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

stages:
  - name: Test
    if: tag IS NOT present
  - name: Tag on Release
    if: branch = master AND type = push
  - name: Deploy
    if: tag =~ ^v\d+\.\d+\.\d+$

env:
  global:
    - FORCE_COLOR=1 # Ensure colored output (color support is not detected in some cases)

# 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
  # - The bigger depth, the longer update takes (-9999 as proposed in npm docs hangs the process).
  #   Therefore we keep at 3 which should ensure most of dependencies are at latest versions
  # - Depth setting makes optional dependencies not optional (install error crashes process)
  #   Hence we skip install of optional dependencies completely, with --no-optional
  #   Note: this patch works only for npm@5+
  # - npm documents --dev option for dev dependencies update, but it's only --save-dev that works
  - npm update --depth 3 --no-optional --no-save
  - npm update --depth 3 --save-dev --no-save
