Recurry

recurrent REST call scheduler

Note: for delayed jobs please use a queue like kue

These days almost anything can be triggered using REST calls, so meet Recurry. Recurry does recurring REST calls, with a nice degree of (remote) control.

You can think of recurry as cron+flock on a unix platform, except without the files (but a REST interface).

Usage

$ npm install recurry coffee-script
$ echo '{"cache":{"scheduler":[],"timers":[]}}' > cache.json
$ RECURRY_CACHEFILE="cache.json" ./server

NOTE: Recurry supports persistance, but does not require a database (instead it uses a local jsonfile)

Hubot interface

Instead of fiddling with crontab-files, the recurry-hubot module allows hubot interfacing with the REST api:

  • starting, stopping, pausing, resuming recurring REST calls
  • adding and removing REST calls including payload

Make sure you run npm install recurry-hubot in your hubot rootdir, and get in control:

hubot> recurry

id           method  url                          payload  scheduler  triggered  triggered_last            status   timer
