Oftmals benötigen die Builds bei CI-Plattformen wie Travis CI, AppVeyor und CircleCI in vielen Fällen recht lange.

Die folgenden Tipps werden regelmßig erweitert und können die benötigte Zeit pro Build drastisch senken.

Caches

AppVeyor

composer

cache:
  - %LOCALAPPDATA%\Composer\files

node_modules

cache:
  - node_modules

npm

cache:
  - C:\Users\appveyor\AppData\Roaming\npm-cache

yarn

cache:
  - %LOCALAPPDATA%\Yarn

CircleCI

composer

    steps:
      - checkout
      - restore_cache:
          keys:
            - composer-v1-{{ checksum "composer.lock" }}
            - composer-v1-
      - run: composer install -n --prefer-dist
      - save_cache:
          key: composer-v1-{{ checksum "composer.lock" }}
          paths:
            - vendor

node_modules

    steps:
      - checkout
      - restore_cache:
          name: Restore npm Cache
          keys:
            - npm-{{ .Branch }}-{{ checksum "package-lock.json" }}
            - npm-{{ .Branch }}
            - npm-master
            - npm-
      - run:
          name: Install Dependencies
          command: npm install
      - save_cache:
          name: Save npm Cache
          key: npm-{{ .Branch }}-{{ checksum "package-lock.json" }}
          paths:
            - node_modules/

yarn

    steps:
      - checkout
      - restore_cache:
          name: Restore Yarn Package Cache
          keys:
            - yarn-packages-{{ .Branch }}-{{ checksum "yarn.lock" }}
            - yarn-packages-{{ .Branch }}
            - yarn-packages-master
            - yarn-packages-
      - run:
          name: Install Dependencies
          command: yarn install
      - save_cache:
          name: Save Yarn Package Cache
          key: yarn-packages-{{ .Branch }}-{{ checksum "yarn.lock" }}
          paths:
            - node_modules/

GitLab CI

composer

cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
  - vendor/

node_modules / yarn

cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
  - node_modules/

distributed

[runners.cache]
  Type = "s3"
  ServerAddress = "s3.amazonaws.com"
  AccessKey = "AMAZON_S3_ACCESS_KEY"
  SecretKey = "AMAZON_S3_SECRET_KEY"
  BucketName = "runners"
  BucketLocation = "eu-west-1"
  Insecure = false
  Path = "path/to/prefix"
  Shared = false

local caches

[[runners]]
  cache_dir = ""

Docker

[runners.docker]
  disable_cache = false
  cache_dir = ""

Travis CI

composer

cache:
  directories:
    - "$HOME/.composer/cache/files"

node_modules

cache:
  directories:
    - node_modules

npm

cache:
  directories:
    - "$HOME/.npm"

yarn

cache:
  yarn: true

shallow Clones

AppVeyor

clone_depth: 5

GitLab CI

variables:
  GIT_DEPTH: "5"

Travis CI

git:
  checkout: 5

Build Matrix / Stages

CircleCI

version: 2
jobs:
  test:
    parallelism: 4
     steps:
       - run:
       - run:
       - run:
       - run:

GitLab CI

stages:
  - build
  - test
  - deploy

parallel 1-1:
  stage: build
  script: make build dependencies

parallel 1-2:
  stage: build
  script: make build artifacts

parallel 2:
  stage: test
  script: make test

parallel 3:
  stage: deploy
  script: make deploy

Travis CI

env:
  - TEST_SUITE=units
  - TEST_SUITE=integration

matrix:
  include:
    - node_js: 8
    - node_js: 10

script: "npm run test:$TEST_SUITE"

npm ci

Und natürlich alternativ npm ci statt npm i, aber dann kann der Cache für node_modules nicht mehr genutzt werden.
