Install Node.JS version pinned at `engines` in `package.json` on GitHub Actions Workflow

action.yml

on:
  push:
    branches:
      - master

jobs:
  test:
    runs-on: ubuntu-latest
  
    steps:
      - uses: actions/checkout@v1

      # extract `engines.node` from package.json and save it to output
      - name: Get Node.JS version from package.json
        id: get-versions
        run: echo ::set-output name=node::$(jq -r .engines.node ./package.json)

      - uses: actions/setup-node@v1
        with:
          node-version: ${{steps.get-versions.outputs.node}}

For anyone else who finds this via Google, here's a run line that works with GitHub's deprecation of ::set-output:

run: echo "node=$(jq -r .engines.node ./package.json)" >> $GITHUB_OUTPUT

There's a built-in way - https://github.com/actions/setup-node/blob/main/docs/advanced-usage.md#node-version-file

@karthikeyan-arumugam-1558 is correct, simply specify node-version-file: 'package.json' under the with: for the Setup Node action to accomplish the above.
