Handle errors thrown by require() module in node.js

Question

Handle errors thrown by require() module in node.js

having a bit of a snag in my code when trying to require() modules that don't exists. The code loops through a directory and does a var appname = require('path') on each folder. This works for appropriately configured modules but throws: Error: Cannot find module when the loop hits a non-module.

I want to be able to handle this error gracefully, instead of letting it stop my entire process. So in short, how does one catch an error thrown by require()?

thanks!

looks like a try/catch block does the trick on this e.g.

try {
 // a path we KNOW is totally bogus and not a module
 require('./apps/npm-debug.log/app.js')
}
catch (e) {
 console.log('oh no big error')
 console.log(e)
}
