scripting

问题 I am developing a REST api with Node.js on Heroku, and one the drivers is giving me problems (I reported that to the driver creator already), but basically a restart of the dynos every half an hour or so seems to fix this.

I checked out the scheduler documentation, but it didn't make much sense Thanks! 回答1: You can do what
