# Owncast Backend Architecture
|
||||
|
||||
Work in progress documentation detailing the backend architecture of Owncast.
|
||||
This is a work in progress document detailing the future backend architecture of Owncast. It should be seen as a living document until a refactor of the backend is complete.
|
||||
|
||||
## Structure
|
||||
## Dependencies
|
||||
|
||||
WIP
|
||||
Dependencies are services that are required across the application. This can be things like the chat service or a data repository for config values or user data.
|
||||
|
||||
Note: A better name that "dependencies" might be clearer. Perhaps "services" or "providers".
|
||||
|
||||
TODO: Have a complete list of dependencies.
|
||||
|
||||
### Data Repositories
|
||||
|
||||
The repository pattern provides a layer of abstraction between the application and the data store, allowing the application to interact with the data store through a well-defined interface, rather than directly accessing the data store. This helps to decouple the application from the data store.
|
||||
|
||||
TODO: List out the repositories and what they do.
|
||||
|
||||
Learn more about the [repository pattern](https://techinscribed.com/different-approaches-to-pass-database-connection-into-controllers-in-golang/).
|
||||
|
||||
### Application Controller
|
||||
|
||||
The `AppController` has references to all the dependencies and serves as an arbiter between consumers of these services and the services themselves.
|
||||
|
||||
A reference to the `AppController` is passed in to the all the core functionality in the application and each package would have its own interface that `AppController` implements. This can include getting access to dependency services like getting access to the chat service, getting access to the config repository values or knowing application state such as if a stream is live or how many viewers are watching via metrics.
|
||||
|
||||
TODO: Show examples of how the application is passed in to packages and how to reference dependencies through it.
