How to check in node if module exists and if exists to load?

Issue

I need to check if file/(custom)module js exists under some path. I tried like

var m = require('/home/test_node_project/per');
but it throws error when there is no per.js in path.
I thought to check with
fs if file exists but I don’t want to add '.js' as suffix if is possible to check without that.

Solution

Require is a synchronous operation so you can just wrap it in a try/catch.

try {
    var m = require('/home/test_node_project/per');
    // do stuff
} catch (ex) {
    handleErr(ex);
}
