GitHub Actions now allows you to take step outputs and output them into other jobs. Now if you have a job that is dependent on some data from another job, instead of needing to save it in a file and upload an Artifact, you can just use Job Outputs and save just the data itself with minimal encoding:

name: Do things
on: push
jobs:
  job1:
    runs-on: ubuntu-latest
    outputs:
      url: $ # map step output to job output
    steps:
      - id: step1
        name: send url to other job
        run: echo "::set-output name=url::https://google.com"

  job2:
    runs-on: ubuntu-latest
    needs: job1
    steps:
      - run: user/some-action@v1
        with:
          url: $ # grab job output here
