Question: Is it possible to load parts of an app dynamically?

[flosse]

Let's say we're going a complex app that consist of two layers

• one layer that is for visitors
• and a additional layer for logged-in users with multiple tools

It would be cool to load the second layer only if necessary.
How would you do this?

Some options:

1. Two standalone Seed apps.
2. Lazy-load 2nd WASM module with JS. Communication between modules through JS.
3. Lazy-load 2nd WASM module with app module. Communication between modules indirectly through JS. Example.
4. Dynamic linking. WIP. Docs. A guy tried it with C.

If you really need it now, I recommend to use 1 or 2. 3 is ugly and 4 is the future.

Fortunately I don't need it now but I need to think about it now for the future ;-)

I'll close this issue because the question is answered. And hopefully I'll once contribute with a PR that shows an elegant example :)
