React-native-code-push: React native unbundling with --indexed-unbundle

[thecachedbyte]

As I can clearly see unbundling is not supported by code push right now #778 #1102

Just wondering if code push will be able to support unbundling with --indexed-unbundle?

Just for reference
--indexed-unbundle is an option provided by react-native unbundle to create a single indexed file instead of multiple bundles. Check here

Since "react native bundle" and "react native unbundle with --indexed-unbundle" is creating a single bundle then ideally it should work.

Currently, we are getting an error (Could not get BatchedBridge, make sure your bundle is packaged correctly). We are still investigating if its a core react native issue or code push unbundle issue or a miss at our end.

Till then I just want to validate this thought of code push supporting unbundling with --indexed-unbundle. Please let me know if my assumption holds true or not.

Thanks in advance.

Versions
React native - ^0.49.3
React native code push - 5.3.2

Hey @sergey-akhalkov @ruslan-bikkinin, sorry to bother you for this issue, but it seems that in the past two issues related to this there have not been many steps forward (#1102, #778) to supporting it and the plan from the RN Core is to push for this feature to be "on by default" in a future release - you can read the details here.

👍 for this, unbundling has significant performance increase on app load and this stops us from using code push on android at the moment

As of now, we don't have plans to support unbundle, but we can definitely see the value in it and why it could be a great addition to the CodePush feature set. Our backlog is pretty filled at the moment, but this is something the team is going to look into. I'm going to close this for now, but will revisit and update this after discussion/investigation with the team.

Hi all! I've just tested unbundling with CodePush and it seems that single unbundled indexed file works like ordinary RN bundle on both iOS and Android.

@thecachedbyte you mentioned that now you are blocked by Could not get BatchedBridge error. Could you provide more details about that issue as I haven't faced with it?(perhaps it would be better to start new thread)

@lithin did you get performance increasing by using default unbundling or with option --indexed-unbundle? The question is if it's enough for you to have a single unbundled indexed file to get performance improvements? During my investigation I've faced with crash if I try to run multiple files unbundled package from file system not from apk assets.

@NickToropov Thanks for the update. Is it possible for you to share the sample app you worked on? Meanwhile, I will gather more information and reply.

@NickToropov Unfortunately we never got it working, and from what I've gathered here and on Twitter, I . understood that it's not actually possible to do this at the moment. If you got it working though, it'd be great to see an example repo?

@Zakeelm, RAM bundles / unbundling was something that i worked on, just before I left. This is actually already possible in Code Push without much changes - I think we just need an "official" way for RAM bundles to be supported .

Hi guys! I may have been a bit hasty. Yesterday I've faced with Could not get BatchedBridge error on Android when tried to prepare demo app. The error occurs even on pure RN application with --indexed-ram-bundle(replacement for --indexed-unbundle) option. So we have to wait till it's fixed in RN or any kind of workaround suggested. Here is a link to RN issue: https://github.com/facebook/react-native/issues/21282
