# Independent Phoenix LiveView Micro-UIs Experiment
## Motivation
- allow multiple teams to deploy parts of a LiveView independently with maximum simplicity
- there's no settled optimum yet, ideas are welcome
## Current Architecture
- 3 independent nodes connected in a cluster
- [main_app](./main_app/) acts as the front-end, serving the [main page](main_app/lib/main_app_web/live/main_live.ex)
- [global_service](./global_service/) and [private_service](./private_service/) [push rendered partial LiveViews](private_service/lib/private_service/private_click_aggregator_service.ex) into Pub/Sub, to which the `main_app` is subscribed, rendering them as they are, within the main view.
- the services also expose their own LiveViews for e.g. their "admin" purposes
### Challenges
- very chatty/wasteful:
- rendered partial HTML views are sent from the services, instead of the optimized configuration as known in LiveView
- current docker compose / libcluster config creates a sporadically disconnected cluster
- presence messages seem to not reach the services
- work-around: when a main LiveView is mounted, a custom `hi` message is published into the `arrivals` channel, requesting a rendered UI from the services.
### Pending Ideas
- 3 LiveView sockets
- potentially served via the same reverse proxy under different paths
- other approaches, unifying the LiveView socket?
- when a service goes doesn / hasn't sent updates in a while, show a `currently unavailable` message in the main view
- custom monitor?
- custom scheduled messages to `self()` in main LiveView?
### Failed Approaches
- trying to render the diffs only:
- unfortunately, this failed with the diff (?) functions not being present on the `main_app`
## Start with process-compose
- install [process-compose](https://f1bonacc1.github.io/process-compose/installation/)
- `process-compose``
- → http://localhost:4000
- http://localhost:4001
- http://localhost:4002
## Start with docker compose
- `docker compose up` (with other options depending on the needs)
- → http://localhost:4001
- http://localhost:4001/services/global
- http://localhost:4001/services/private
