全局变量未在 cron 文件中的 node.js 服务器上定义

Question

I have a node.js server which has a global variable called Sys:

  const Sys = new require('../Boot/Sys');
  // Make Sys a global variable
  global.Sys = Sys;

I also have a file completely running separately using cron every minute the problem is that I need to modify the global variable in my cron file but it is undefined so my question is can I somehow define a global variable that is accessible in my cron file? im just starting to work with servers so forgive me if i am asking basics.

Answer 1

You should just be able to define the variable normally outside of the cron function. If for some reason that doesn't work you could use something like node-cache to cache the variable.
