I am using VueJS and I've been bitten several times by the fact that it swallows all errors (undefined properties in templates as well as calling undefined errors in methods).

Is there a way to turn on all errors, or at least all errors happening in JS (and not in templates)?

    Did you try using debug Vue.config.debug = true? With this Vue will print stacktrace errors/warnings. Commented Sep 20, 2016 at 14:38

    Also ensure to be using the develpment version. From docs: "don’t use the minified version during development. You will miss out all the nice warnings for common mistakes!" Commented Oct 19, 2016 at 15:06
  • I'll use the debug option then. And thanks @ragnar. That will create a complex setup though (differentiating dev and prod), too bad exceptions are just swallowed out of the box :/ Commented Oct 20, 2016 at 6:37
  • Vue.config.debug doesn't exist in 2.0. I think you just want to NOT use the minified version and make sure you DON't set Vue.config.silent to true. Commented Oct 21, 2016 at 20:41

From the comments:

  • don't use the minified version in development

For VueJS 1.x:

  • turn on the "debug" mode (this doesn't exist in Vue 2.0 anymore)

    config: {
    debug: true
}

    or Vue.config.debug = true

How would you make sure that errors are properly logged to Sentry or Bugsnag in production (in case of bugs that have not been discovered while develping) ?
@conradk I honestly don't know, maybe you should ask that in a separate question to get answers
