Cronjob to web hooks.
Momo was designed to work as a worker (continuous process), and call it hooks when cron job should be executed.
Also Momo DOES NOT USE A DATABASE, it uses remote CSV file to fetch it hook cron list.
obs.: All dates are forced to be on GMT.
- follow-redirects following redirects in case of webhook link is a redirect
- newrelic for new relic analysis
All Configuration need to be done through ENV IVARS.
CRONS_URL- End point to fetch cronjob list. REQUIREDCRON_FETCH_LOOP- Time interval to Momo fetchCRONS_URLin milliseconds - REQUIRED normally it should be 3600000
NEW_RELIC_APP_NAME- New Relic application name. REQUIREDNEW_RELIC_LICENSE_KEY- New Relic license key. REQUIRED
Start server
$ 'node server.js' OR 'foreman start'Momo CronJob syntax is very near to the Unix cron syntax, BUT it'll not allow ? character ,words and special keywords. (the last 2, are on roadmap.)
