Small app that runs as a cron script on Webtask platform and checks if an URL get a response, and allows also to check if the body match with a given string or a regex expression.

If the check fails posts a message in a Slack channel.

$ wt cron schedule \
     -n checkcron \
     --secret "URL=http://theurltocheck.com/path/to/uri" \
     --secret STATUS=200 \
     --secret TIMEOUT=5000 \
     --secret "BODY=Text expected" \
     --secret "REGEX=Regex expression" \
     --secret SLACK_TOKEN=THETOKEN \
     --secret SLACK_CHANNEL=CHANNELNAME \
     "*/2 * * * *" \
     check.js

• -n checkcron: the name of the cron process.
• --secret URL: The URL to check.
• --secret STATUS: (optional) The status expected, default 200.
• --secret TIMEOUT: (optional) Milliseconds to wait the response before aborting the request, default 10000 (10 seconds).
• --secret BODY: (optional) A text expected in the body.
• --secret REGEX: (optional), regex expression expected to match with the body.
• --secret SLACK_TOKEN: the Slack API token, go to https://api.slack.com/web#authentication to get a token.

You can also install the script directly to Webtask platform without having this project downloaded in your local machine with:
