Is there a job scheduler library for node js

Question

Is there some cron like library that would let me schedule some function to be ran at certain time  15 30 for example  not x hours from now etc   If there isn t this kind of library how this should be implemented  Should I just set callback to be called every second and check the time and start jobs scheduled for the time or what

This won t be suitable for everyone  but if your application is already setup to take commands via a socket  you can use netcat to issue a commands via cron proper   echo  mycommand    nc -U  tmp myapp sock

I am the auhor of node-runnr   It have a very simple approach to create job  Also its very easy and clear to declare time and interval   For example  to execute a job at every 10min 20sec   Runnr addIntervalJob  10 20   function          myjob     To do a job at 10am and 3pm daily   Runnr addDailyJob   10 0 0    15 0 0    function          myjob     Its that simple  For further detail  https   github com Saquib764 node-runnr

I am using kue  https   github com learnboost kue   It is pretty nice    The official features and my comments    delayed jobs   If you want to let the job run at a specific time  calculate the milliseconds between that time and now  Call job delay milliseconds    The doc says minutes  which is wrong   Don t forget to add  jobs promote     when you init jobs   job event and progress pubsub   I don t understand it   rich integrated UI   Very useful  You can check the job status  done  running  delayed  in integrated UI and don t need to write any code  And you can delete old records in UI   infinite scrolling  Sometimes not working  Have to refresh   UI progress indication  Good for the time-consuming jobs   job specific logging  Because they are delayed jobs  you should log useful info in the job and check later through UI   powered by Redis  Very useful  When you restart your node js app  all job records are still there and the scheduled jobs will execute too   optional retries  Nice   full-text search capabilities  Good   RESTful JSON API  Sound good  but I never use it       Edit    kue is not a cron like library  By default kue does not supports job which runs repeatedly  e g  every Sunday
