Fresh Ember addon indirectly depends on core-js@2

[paddor]

🐞 Describe the Bug

I've noticed that even a freshly initialized Ember 5.12.0 addon depends on core-js@2.6.12, which is deprecated. This seems to happen because:

$ pnpm why -r core-js@2.6.12 --long

🔬 Minimal Reproduction

ember addon my-app-webui-addon --skip-git --skip-npm

😕 Actual Behavior

Deprecated packages are in the dependencies.

🤔 Expected Behavior

I expect non-deprecated packages are in the dependencies.

🌍 Environment

• Ember-CLI: 5.12.0
• Node.js/npm: v22.12.0 lts/jod
• OS: Ubuntu 22.04

[NullVoxPopuli]

All of this is from babel -- not much we can do? tho, do you have suggestions?

[paddor]

By "babel" do you mean ember-cli-babel? Because that seems to be the culprit. It seems to me that ember-cli-babel@7.26.11 is installed, which from December 2021 and depends on @babel/polyfill, which, according to [1], has long been deprecated.

I don't have any suggestions as I find the JS world quite confusing. How does this happen? How can it be fixed?

[1] https://babeljs.io/docs/babel-polyfill

[NullVoxPopuli]

well, just @babel/polyfill

 @babel/polyfill 7.12.1
  └── core-js 2.6.12

are you saying this isn't needed anymore?

[paddor]

I don't know. Is it needed? According to the Babel website itself, @babel/polyfill has been deprecated since Babel 7.4.0.

I initialized a new Ember 5.12 addon to cross-check what a modern addon would depend on and it seems to depend on ancient packages.

What I did:

nvm use lts/jod
ember version #=> 5.12.0
ember addon my-app-webui-addon --skip-git
cd my-app-webui-addon
pnpm install

Then when checking for ember-cli-babel/core-js@2, I get this:

 ~/d/my-app-webui-addon  $ pnpm why -r ember-cli-babel --long --no-optional --prod --parseable

Where did I go wrong?

[NullVoxPopuli]

we need ember-cli-babel, the main issue is whether or not we can get rid of @babel/polyfill.

A subset of your initial query would be helpful

pnpm why @babel/polyfill

looks like you'd get

• broccoli-babel-transpiler
• ember-cli-babel

not sure of any others.
but we'd probably want to PR the removal of @babel/polyfill to those two projects 🎉

Which, I'm a huge fan of, as less dependencies is better for everyone!

[paddor]

Querying for @babel/polyfill outputs nothing.

Is this helpful instead?

Honestly I don't know much about JS stuff. I just know that core-js@2 is not maintained anymore and I was surprised that a modern Ember addon would depend on it.

[NullVoxPopuli]

not particularly, the output from --parseable doesn't give us the hierarchy

I was surprised that a modern Ember addon would depend on it.

this is fair -- however the build system also supports libraries from the dark ages -- compatibility or rather "stability without stagnation" is ember's motto

[bertdeblock]

ember-cli-babel v8 got rid of @babel/polyfill, so we just need to make sure that ember-cli-babel v7 isn't used anymore.

[paddor]

How do I use ember-cli-babel v8? I just tried removing the meta package ember-data and replaced with with what I hoped to be the bare minimum: @ember-data/store and @ember-data/model. Unfortunately @ember-data/model@5.3.9 depends on @ember-data/legacy-compat, which indirectly still depends on ember-cli-babel@7.26.11.

[bertdeblock]

You can force v8 using E.g. Yarn resolutions or pnpm overrides, but we should also try to update to v8 in those packages as well.

[paddor]

I've tried using pnpm overrides in our app and two addons like this:

+   "pnpm": {
+     "overrides": {
+       "ember-cli-babel": "^8.2.0"
+     }
+   },

This seems to work. No more core-js@2 causing problems on the CLI with pnpm.

Can this issue be used to coordinate the upgrade to ember-cli-babel v8 in other Ember projects?

[bertdeblock]

I guess it can.
Separate issues in the corresponding repos would help as well, to notify the maintainers.
Updating the addons to the v2 spec (if possible) would fix it as well, as v2 addons don't use ember-cli-babel.
