How to fix EXTEND_PROTOTYPES deprecation ?

[zorn-v]

Just updated deps and got

DEPRECATION: Accessing Ember.EXTEND_PROTOTYPES is deprecated, please migrate to Ember.ENV.EXTEND_PROTOTYPES [deprecation id: ember-env.old-extend-prototypes]

Nothing can find about it

I have standard config in config/environment.js

   EmberENV: {
      FEATURES: {
        // Here you can enable experimental features on an ember canary build
        // e.g. 'with-controller': true
      },
      EXTEND_PROTOTYPES: {
        // Prevent Ember Data from overriding Date.parse.
        Date: false
      }
    },

Follow the deprecation stack trace, find out who/what is accessing Ember.EXTEND_PROTOTYPES and send out a PR...

The only case I have known about this was fixed in an update of ember-inflector, I’d check that first...

Stack trace. I wonder if it help you 😄

ember-source was updated to 3.2.0
I think it is the because

[rwjblue]

Yep, now look at those lines from the stack trace. You should be able to see which addon (or part of your app code) is triggering it. I personally would start with a breakpoint at the resolveInitializer line and see which modules are using Ember.EXPAND_PROTOTYPES. You could also grep/ag/rg in your node_modules for usages of EXPAND_PROTOTYPES...

[zorn-v]

Are you kidding me ?
I DID NOT use EXPAND_PROTOTYPES as well. It exists after standard ember skeleton. I'd tried removing it - no pasaran.
You tell like a troll.

[rwjblue]

A newly generated Ember app does not emit this deprecation message (I just tested via ember new foo && cd foo && ember s), so there is something different about your application that is triggering the deprecation. The things I've described above are just a few ways to track down deprecations like these. I'm sorry that you feel that I am trolling you 😞.

could be ember inspector issue please try disabling ember inspector related: emberjs/ember-inspector#810

[ro0gr]

I also use ember-source@3.2.0 and have the same EXTEND_PROTOTYPES deprecation with a similar stactrace. It comes from the ember-inflector/ext/string

[rwjblue]

@ro0gr - That line was recently updated to avoid deprecation, can you please confirm that you are on the latest version?

[ro0gr]

@rwjblue hm.. might be related to the fact I've updated ember-source package separately. I'm not sure right now. Will check it next week.

[ro0gr]

So in my case it was an outdated transitive ember-inflector@2.2.0 dependency.

yarn upgrade ember-cli-mirage ember-data fixed the issue for me.

[rwjblue]

Awesome, thank you for chiming back in to confirm that fixed it for you!

[zorn-v]

I return "^" to "~" on ember-source, ember-data and ember-cli to semver in package.json and 3.1.0
I think problem in ember-data, coz it use old version of ember-inflector which use Ember.EXTEND_PROTOTYPES

Should resolve when ember-data 3.2 released.
