Realm + Reanimated v2 w/ JSC causes Realm to not work #3837

liamjones · 2021-07-08T07:13:17Z

Goals

Use react-native-reanimated v2 alongside Realm. Reanimated v2 used to require Hermes (and I'm aware RealmJS's Hermes support is still WIP) but v2.2.0+ have added JSC support as well [1].

Expected Results

The two to live together happily.

Actual Results

In our instance - the app runs fine on iOS but on Android we can save stuff to Realm but reloading it results in objects being undefined. Others have reported app crashes with minimal repros to the renimated project already [2] but I thought I'd report it here too incase it can be fixed from the Realm side.

Steps to Reproduce

Install Realm + react-native-reanimated v2.2.0+ in the same app without Hermes - attempt to use Realm on Android.

Code Sample

See minimal repro on this ticket: software-mansion/react-native-reanimated#2028

Version of Realm and Tooling

Realm JS SDK Version: 10.4.1
Node or React Native: 0.63.4
Client OS & Version: Android
Which debugger for React Native: N/A

liamjones · 2021-07-08T07:26:53Z

Oh, and I assume the conflict happens because of the low-level way both modules bind themselves into the JSC?

kneth · 2021-07-08T15:04:53Z

Thank you for cross-posting. We will have to investigate it further to understand the interaction between JavaScriptCore and the two libraries is.

dev-babar · 2021-07-09T14:24:31Z

I have the same issue, downgrading to Reanimated v1 works for me.

liamjones · 2021-07-09T14:25:27Z

Oh! Yes, v1 works here too. It's only an issue with v2 (which we're trying to upgrade to for the new API).

wanderson-ra · 2021-07-16T14:00:39Z

The problem is hermes. Reanimated v2 needs enableHermes: true. However realm is not compatible with hermes yet.

liamjones · 2021-07-16T18:50:42Z

@wanderson-ra If you read the opening post you'll see that JSC is supported since Reanimated 2.2.0

liamjones · 2021-08-11T07:55:27Z

Hi @kneth, any news on this one yet?

We're starting on the implementation of something which would be a lot simpler in reanimated v2 due to the new API but we're having to stick to v1 for now due to this conflict with Realm.

FYI, I've retested with the latest versions of both projects (Realm 10.6.1 and Reanimated 2.2.0) but, unsurprisingly, it still happens. Interestingly the behaviour seems somewhat variable? Possibly a race between the two modules hooking into the JSC?

If I use the minimal repro off of the reanimated ticket (https://github.com/limpbrains/reanimated-2-playground) it doesn't always crash when I hit the 'write to realm' button. Sometimes it crashes the app (seems more likely if I tap the button as soon as it's available, rather than waiting) but when it does 'work' I've seen varying output from the console.log statement:

[Tue Aug 10 2021 18:08:34.961]  LOG      created two tasks:  &
...
[Tue Aug 10 2021 18:09:01.886]  LOG      created two tasks: Wrapper & Wrapper
...
[Tue Aug 10 2021 18:09:26.881]  LOG      created two tasks: undefined & undefined

Also, if there's anything extra we can provide to help (tombstones, etc) let us know.

enigmablue · 2021-08-30T14:29:02Z

Same having this problem with realm + reanimated v2 which is a major problem as reanimated v2 looks like a requirement for some camera packages i need

software-mansion/react-native-reanimated#1424

mklb · 2021-10-04T13:48:18Z

Same here. iOS works. Android writes result in empty objects.

r.write(() => {
  var anObject = myRealm.create('SomeModel', {
    id: 1,
    // other variables
  })
  console.log(anObject, anObject.id) // => {} undefined
})

Hermes is disabled of course.

"realm": "^10.8.0",
"react-native": "^0.65.1",
"react-native-reanimated": "^2.3.0-beta.2",

Downgrading react-native-reanimated to v1 helped as mentioned above.

buzunboy · 2021-12-31T15:16:15Z

Same problem, we have to use reanimated v2 to for other dependencies, and it's urgent for us to find a solution to use both together. Looking forward to hear more

hungnv2010 · 2022-01-28T08:17:18Z

this problem doesn't seem to be solved.

somebody32 · 2022-01-28T08:32:34Z

Anyone who is eager to have this issue fixed, please try the latest betas of 10.20 with hermes support. In my experiments, it was working out of the box

Hi @somebody32 , I still crash ios app on testflight

somebody32 · 2022-01-28T08:55:40Z

@hungnv2010 then please attach some reproducible example, because the original issue was about data loss or crash on reload. Looks like you have something different here

kraenhansen · 2022-01-28T09:31:29Z

@hungnv2010 we're not aware of any crashes happening with Realm JS 10.20.0-beta.1 and the Reanimated library.
So as @somebody32 says, please create a new issue with a reproduction, this helps us a lot when debugging an issue like this.

hungnv2010 · 2022-01-28T09:46:00Z

@hungnv2010 then please attach some reproducible example, because the original issue was about data loss or crash on reload. Looks like you have something different here

@somebody32 I don't know if the problem arises from the realm or from react-native-reanimated. I have upgraded from 5.0.3 to 10.20.0-beta.1 and react-native-reanimated from v1 to v2 with Hermes enabled, debug still runs normally testflight then crash app. both 5.0.3 and 10.20.0-beta.1 crashed a few times when open app.

Thank you so much, I was having issues for days and this fixed it

takameyer · 2022-01-31T08:35:54Z

Our Hermes release branch currently solves all issues related to Reanimated v2. Please use this branch if your project needs react-native-reanimated. If you are having any issues with the current Hermes release branch, please open a new ticket describing your issue.

To quickly switch to this release branch, use the following command:

npm install realm@hermes

We are actively working on this branch, so any input would be appreciated 😃

liamjones · 2022-01-31T08:56:00Z

Our Hermes release branch currently solves all issues related to Reanimated v2.

@takameyer does this include when running them together with the JSC rather than Hermes?

takameyer · 2022-01-31T08:57:30Z

@liamjones Yes, you do not need to enable Hermes for this to work.
A part of the hermes effort was fixing the bridge between Android and the javascript engine. This fixes the conflict we were having with the way react-native-reanimated establishes this bridge.

liamjones · 2022-01-31T09:00:50Z

Awesome, thanks!

mfbx9da4 · 2022-06-17T12:24:59Z

I'm not sure upgrading to realm@hermes is really a solution here as it currently has some major performance issues. The other workaround is downgrading reanimated, are there any other potential workarounds?

tomduncalf · 2022-06-17T13:26:21Z

I don't think there's any other workarounds that I am aware of, although perhaps someone from the community has some ideas. We're hoping we can solve the performance regressions soon. Sorry, I realise it's not ideal, but since realising the impact we are treating this as a high priority.

mfbx9da4 · 2022-06-17T13:32:03Z

No worries, I know you're working hard on this. I want the JSI implementation to work because when it does it will be 🔥

Sounds like you're close!

I think I'm having the same problem my app keeps crashing when i use realm in drawer or tab navigation but works fine on stack. plzz tell me how to sort this issue. I'm using react native reanimated v2

I'm using realm@hermes as @takameyer suggested and it is working, there are still some random crashes but it is better than without it.

@AzadMohammadi-z Please take a look at https://github.com/realm/realm-js/blob/v11/COMPATIBILITY.md to find a compatible version. Best is to upgrade to latest version but it will also include upgrading React Native.

Thank you so much, My problem is solved

OrenMe · 2023-10-29T12:57:24Z

will this also happen in a project that has reanimated v2 and also realm but as native component of a native module? we are using a native player component that internally uses realm for managing offline download support and having same sort of issues

liamjones · 2023-11-06T17:00:31Z

@OrenMe if you're using one of the Realm native modules only (e.g. realm-java, realm-cocoa, etc rather than realm-js) I don't think you should run into this issue.

It's specifically a conflict between how realm-js and reanimated v2 both want to bind themselves to the JavaScriptCore and do so in a way that there's a conflict between them. The pure native modules won't know about the JSC and won't be attempting to do anything with it.

OrenMe · 2023-11-06T18:50:48Z

thanks @liamjones

Muhammad19Omer · 2024-01-20T19:00:14Z

Hey, bumping this up again. Here's both of my packages:

"react-native-reanimated": "^3.6.1",
"realm": "12.0.0-rc.2",

I had realm 12.6.1 but read somewhere that the rc versions had this fixed. Critical loss in application functionality. Hoping this gets fixed soon.

kraenhansen · 2024-01-21T10:57:51Z

@Muhammad19Omer

read somewhere that the rc versions had this fixed

This is very unlikely, since 12.6.1 is newer - please open a new Issue with the template filled out, to help us narrow the cause of the issue you're seeing.

kraenhansen · 2024-01-21T11:00:38Z

I'm locking the issue for further comments as we believe this has been resolved. If you can reproduce an issue with Realm + Reanimated, please help us pin point any potential issue by opening a new issue with the templated filled out and ideally a minimal reproduction. Thanks!
