This GitHub Action deploys your static site to Netlify or Vercel by triggering a build hook from the convenience of your GitHub repository. You can also set it up to run by cron.

The Action will skip deployment when no changes are detected since the last run. To store the commit id of the current deployment GitHub cache mechanism is used.

You can also pass always_deploy set to true to trigger deployment without checking for changes.

To obtain build hook URL:

1. Sign in with Netlify.
2. Select the site you want to deploy. Go to Site configuration.
3. Select Build & deploy.
4. Scroll down to Build hooks and click Add build hook.
5. Enter a descriptive name of your hook and click Save.
6. Your webook URL has the following format: https://api.netlify.com/build_hooks/12345679abcdef. You shouldn't share it with anyone else. I recommend saving it in Secrets and variables section of your GitHub repository settings.
7. Create your workflow as follows:

name: Deploy static site
on:
  workflow_dispatch:

jobs:
  DeploySite:
    runs-on: ubuntu-latest
    steps:
      - name: Deploy site
        uses: lwojcik/github-action-deploy-static-site@v1
        with:
          platform: netlify
          netlify_deploy_hook_url: ${{ secrets.NETLIFY_DEPLOY_HOOK_URL }}
          # always_deploy: true - if you want to skip checking for changes

To disable automatic builds and obtain build hook URL:

1. Sign in with Vercel.
2. Select the project you want to deploy. Go to Settings.
3. Select Git. Head to Deploy Hooks section and create a new hook.
4. Your webhook URL has the following format: https://api.vercel.com/v1/integrations/deploy/12345679abcdef. You shouldn't share it with anyone else. I recommend saving it in Secrets and variables section of your GitHub repository settings.
