Share randomly generated variable across .js and .ejs files with nodeJS

Question

I am generating a random number inside a javascript file that I need to pass through to an .ejs file. Obivously I can't just reproduce it there because it is random.

I am working with these files: app.js, game.js and game.ejs. I need to use the variable in both game files.

This is the variable I need to be shared

var num = Math.floor(Math.random()*4)

I already tried passing the variable through my app.js to the game.ejs which worked. I can still not work with it in my game.js though.

Any help is appreciated

make this varibale global like

global.num = Math.floor(Math.random()*4)

now use it at any place inside your environment.

Global varibales must be handled with care as it pollutes

Thanks for the quick answer. In which file would I define this variable? – Philipp K Mar 07 '18 at 18:41
you can maintain a separate file for global variables or else you can just use it anywhere. But be cautious with naming as you may overwrite the value by mistake at other place – Saikat Hajra Mar 07 '18 at 18:42
@SaikatHajra will it also accessible on frontend as opp wants to use in `game.ejs` ?? – Nikhil Savaliya Mar 07 '18 at 18:46
you can only access by rendering – Saikat Hajra Mar 07 '18 at 18:52
