How to separate js bundle to frameworkBundle and appBundle?

js bundle is more 500k+, but business code is less then 10%

Hey Richard-Cao, thanks for reporting this issue!

React Native, as you've probably heard, is getting really popular and truth is we're getting a bit overwhelmed by the activity surrounding it. There are just too many issues for us to manage properly.

• If you don't know how to do something or something is not working as you expect but not sure it's a bug, please ask on StackOverflow with the tag react-native or for more real time interactions, ask on Discord in the #react-native channel.
• If this is a feature request or a bug that you would like to be fixed, please report it on Product Pains. It has a ranking feature that lets us focus on the most important issues the community is experiencing.
• We welcome clear issues and PRs that are ready for in-depth discussion. Please provide screenshots where appropriate and always mention the version of React Native you're using. Thank you for your contributions!

Wow, I just wanna fix this issue, and have tried https://github.com/mjohnston/react-native-webpack-server/ but failed.

Also I tried to get a dev version bundle and copy the framework code as framework.jsbundle, but when I package the business code, I cannot analysis the correct dependencies.

Looking forward this solutions~~~~

@Richard-Cao IOS also have this issue~~

[Richard-Cao]

@Creemli Looking forward……

@Richard-Cao Help to remove the [Android] tag and then more people can search this issue.

[Richard-Cao]

@Creemli ok

What's the purpose of splitting the bundle? Is it just to make incremental app updates lighter weight, or is there some runtime goal you're trying to accomplish?

[Richard-Cao]

both @corbt

[corbt]

To help me understand the scope of this, what are the use cases for this beyond just making lighter-weight app updates (which I get)?

[Creemli]

@corbt Yeah, this can make user download less code when updating.
And if we can separate them, we maybe not have to bundle the whole codes, we can combine any business project with the framework code, it's lighter, I think.

I think @martinbigio was looking into this.

[martinbigio]

Yeah, we were looking into this mostly to help on TTI but decided to pursue another approach, namely unbundling. To make code downloading faster it's not actually necessary to have multiple bundles but to use a "more clever" protocol (i.e.: one that could send diffs only).

@martinbigio cool
