A simple script that uses Github Actions and ntfy.sh to periodically poll websites and notify you of changes in the HTML.

1. Fork this repository.

2. Go to the repo's settings > Actions > Workflow permissions and set to Read and write permissions.

3. Set your ntfy.sh topic name as a repository secret with name the NTFY_TOPIC.

4. Edit .github/workflows/poll-websites line 6 with the cron schedule expression of your preference. Default is "0 6 * * *" (daily at 6 am).

5. Edit watch.json.

You can specify which websites to poll and under what conditions the script should notify you in watch.json.

The file consists of a list of key-value pairs. You specify the name of each website / notification as the key of an entry. This is the name that will appear in notifications. The value of each key must be another object and contain at least:

• "url": the url to monitor (with GET requests)
• "on": the criteria that will trigger a notification. "in" will notify if the text in "txt" is in the retried HTML, "not_in" the opposite, and "change" will do so if the page changes from a cached version.

You must include a "txt" field if "on" is either "in" or "not_in".

Note: "change" will automatically cache the page the first time the script is ran and will overwrites cached version when a change is detected.
