- app/

Tests and it's configuration:
- dev/

CircleCI setup

.circleci/config.yml

At least in theory...

You should know!

If you run out of memory, add to job:

-d memory_limit=1024M

You can name your tasks:

-run:
  name: My Custom task name

Use cache!

  - restore_cache:
    keys:
      - v2-dependencies-{{ checksum "composer.json" }}

  - save_cache:
      paths:
        - ~/.composer/cache/
      key: v2-dependencies-{{ checksum "composer.json" }}

Try to use existing cache:

Save newly pulled dependencies:
