Data: [email protected]: circular dependency

[nfc036]

With [email protected] I get a "circular dependency"-Warning/Error in console when running "ember serve".

Circular dependency: ..\..\..\..\Users\username\TEMP\broccoli-9436umqGtnnqeeVy\cache-200-rollup\build\-private\system\model\model.js -> ..\..\..\..\Users\username\TEMP\broccoli-9436umqGtnnqeeVy\cache-200-rollup\build\-private\system\model\internal-model.js -> ..\..\..\..\Users\username\TEMP\broccoli-9436umqGtnnqeeVy\cache-200-rollup\build\-private\system\references.js -> ..\..\..\..\Users\username\TEMP\broccoli-9436umqGtnnqeeVy\cache-200-rollup\build\-private\system\references\belongs-to.js -> ..\..\..\..\Users\username\TEMP\broccoli-9436umqGtnnqeeVy\cache-200-rollup\build\-private\system\model\model.js

Without temporary directories the circular reference is:

-private\system\model\model.js ->
-private\system\model\internal-model.js ->
-private\system\references.js ->
-private\system\references\belongs-to.js ->
-private\system\model\model.js 

Beside this, the process starts normally. However, the message is irritating.

I'm working on windows with [email protected]. [email protected] does not show this behavior.

This warning printed here is noisy but not problematic. We will try to silence it going forward, but it is the unfortunate artifact of how importing classes for Typescript conflicts with rollup's circular dependency import checks.

Seeing this as well on a new Ember 3.6 app. No issues with Ember Data's functionality, only issue is the warning message!

@rinoldsimon it looks like you do have the same warning but it is a different issue that is breaking your build 🤔 I think you should open a new issue (potentially on the ember-cli repo) or ask for some help in #help on the Ember Community Discord 👍

It looks like there is a Babel config issue in your case that may be caused by a version inconsistency in something to do with Babel 🤔

[rinoldsimon]

@mansona the build was breaking due to compact: false in my ember-cli-build.js. Removing those lines fixed my issue.

But still, circular dependency warning persists

[Redsandro]

Same issue.

system/model/model.js ->
system/model/internal-model.js -> 
system/references.js -> 
system/references/belongs-to.js -> 
system/model/model.js

I've been trying to get rid of it by commenting out more and more code, thinking this caused fastboot not to work. But I guess that's a totally different issue.

[runspired]

@Redsandro this is not an error and is a misguided warning that we've silenced in more recent builds and releases

[Redsandro]

@runspired thank you for clarifying.

Meanwhile, I figured out what the problem with FastBoot was. It was an unclear error message. Now isn't that ironic? :robot:

(The issue that google suggested was even created by myself last year. Ironiception! :fireworks: )
