  • Steps: Steps are a collection of executable commands which are run during a job.

What are Orbs?

According to the CircleCI’s official document, Orbs are

Orbs are reusable snippets of code that help automate repeated processes, speed up project setup, and make it easy to integrate with third-party tools.

So Orbs are basically like libraries. You can reuse the code that was written by somebody else.

Validate config in your local env

Run the command below.

$ circleci config validate

If you are working with Orbs you can also validate your orb:

$ circleci orb validate /tmp/my_orb.yml

Example

Here is a simple CircleCI configuration for a react project.

version: 2.1
# list orbs you want to use.
orbs:
  node: circleci/node@1.1.6
jobs:
  # This is the name of this job
  jest:
    # Executors define the environment in which the steps of a job will be run
    executor:
      name: node/default
    # Following the usage example of circleci/node@1.1.6.
    # https://circleci.com/orbs/registry/orb/circleci/node?version=1.1.6
    steps:
      - checkout
      - node/with-cache:
          steps:
            - run: yarn install
            - run: yarn test
workflows:
  build-and-test:
    jobs:
