Code Splitting is a technique that splits the code into multiple files, which can be loaded on demand and in parallel.
It can be used to:
- Optimize the initial size of the application and to improve the startup performance by deferring the parsing (only with JSC) and execution (JSC and Hermes) of the non-critical code.
- Dynamically deliver content and features to the users based on runtime factors: user's role, subscription plan, preferences etc.
- For developers and companies: split and isolate pieces of the product to improve scalability and reduce coupling.
For dynamic feature delivery, Code Splitting should be used as a mean to optimize the user experience by deferring the features or deliver a existing features only to a subset of users.
Code Splitting with Re.Pack is not designed to add new features dynamically without doing the regular App Store or Play store release. It can be used to deliver fixes or tweaks to additional (split) code, similarly to Code Push, but you should not add new features with it.
Using Code Splitting to deliver new features without a regular App Store release is likely going to violate Apple's App Store Terms and your application might be rejected or banned.
You should provide access to all the features for the App Store review process.
Also, it might be beneficial to highlight that all split features are closely integrated with application and cannot work in isolation - you don't want to introduce confusion that your application might compete with Apple's App Store.
On that note, you might want to avoid using terms like mini-app or mini-app store in favour of modules, components, plugins or simply features.
