# *Untitled Social Media Consumption Project*
|
|
|
|
*(last updated 2023-06-11)*
|
|
|
|
|
|
|
|
This is the main repository for USMCP, formerly "Witch Watch", formerly "What2.Watch",
|
|
etc. etc. USMCP is intended to primarily support the following things as an end user:
|
|
* keep track of things you want to watch, eg, TV shows, movies, videos, etc.
|
|
* including type of thing, whether or not it's private, whether you watched it already, etc.
|
|
* keep track of people you want to watch those things with
|
|
* easy to take all your data with you, no lock-in
|
|
|
|
As an operator, it's meant to be as simple as possible:
|
|
* single binary that can be copied and deployed easily
|
|
* local database (sqlite) and associated files, easily copied and inspected
|
|
* pervasive use of universally unique IDs allows simple merges from other instances
|
|
|
|
As a developer, it's meant to be easy to work on:
|
|
* Pure Rust backend
|
|
* [Axum](https://github.com/tokio-rs/axum) with Tokio for async http routing
|
|
* [SQLx](https://github.com/launchbadge/sqlx) for talking with the database
|
|
* [Askama](https://github.com/djc/askama) for templates
|
|
* [Tantivy](https://github.com/quickwit-oss/tantivy) for full and fuzzy text searching (PLANNED)
|
|
* Simple front end
|
|
* currently unstyled hand-written HTML with no javascript!
|
|
* barely there!
|
|
* a good place for contributing!

## Overview of the code
|
|
|
|
### Rust
|
|
|
|
Like most Rust projects, it's broken up into at least two distinct crates, a [`bin`](src/main.rs) crate that acts as
|
|
a thin veneer over and runner for the main entry point inside the [`lib`](src/lib.rs) crate. The lib
|
|
crate exposes a couple public functions and datastructures used in the bin crate and in testing, but
|
|
otherwise mostly brings some lib-crate-wide types into the `crate::` scope and defines the `app`
|
|
method that returns an [Axum::Router](https://docs.rs/axum/latest/axum/struct.Router.html), and
|
|
currently has all the HTTP route declarations.
|
|
|
|
The full `src` directory currently looks like:
|
|
|
|
``` text
|
|
src
|
|
├── db.rs
|
|
├── generic_handlers.rs
|
|
├── lib.rs
|
|
├── login.rs
|
|
├── main.rs
|
|
├── signup.rs
|
|
├── templates.rs
|
|
├── test_utils.rs
|
|
├── users.rs
|
|
├── util.rs
|
|
└── watches
|
|
├── handlers.rs
|
|
├── mod.rs
|
|
└── templates.rs
|
|
```
|
|
|
|
The simple modules (that is, ones that are a single file without anything from submodules being
|
|
exposed to anywhere else outside themselves) are all under `src/`:
|
|
|
|
* `db.rs`: interfacing with sqlite
|
|
* (this has an inlined external crate for managing login sessions with sqlite, which takes up most of the lines in the file, but should be considered mostly external)
|
|
* `generic_handlers.rs`: callback definitions for serving things like redirects to `/`
|
|
* `login.rs`: error types and handlers for login/logout routes
|
|
* `signup.rs`: error and response types, and handlers, for signup route
|
|
* `templates.rs`: Askama templates for the simple modules
|
|
* `users.rs`: definitions and trait implementations for `User`s
|
|
* `util.rs`: misc useful functions
|
|
|
|
Tests for those modules are kept as submodules inside them.
|
|
|
|
Compound modules, those that are a `mod.rs` file inside a subdirectory of `src/`, will broadly
|
|
follow the example of `src/watches/`:
|
|
|
|
* `watches/mod.rs`: data types and impls for the thing to watch (a `Watch`)
|
|
* `watches/templates.rs`: Askama templates for `Watch`-related pages and objects
|
|
* `watches/handelers.rs`: callbacks and their error types for handling requests to `Watch`-related routes
|
|
|
|
Tests for each are kept as submodules inside each submodule, as with the simple modules.
|
|
|
|
In general, all templates will be available directly under the `crate::` scope, as you can see in
|
|
the `use` statements in `lib.rs`, but handlers are not.
|
|
|
|
### Non-Rust
|
|
|
|
At the project root, next to the `src/` directory, are two other directories:
|
|
|
|
* `migrations/`: SQL files that define the schemas and add things like indexs and triggers
|
|
* `templates/`: HTML templates used by one or more Askama templates to control presentation
|
|
|
|
It's likely that there will be `css/` and `javascript` directories in the future. Likewise code for
|
|
helping with deploying or monitoring.
|
|
|
|
## Development goals
|
|
|
|
Currently, I think the backend is 40-60% "complete", where 100% would mean that all use cases
|
|
outlined at the top are working. The front end is approximately unstarted.
|
|
|
|
The current development priorities are, in order from most to least important,
|
|
|
|
* finishing the `watches` module, allowing adding things to watch to the system and to your own watchlist
|
|
* more front-end templates to support the `watches` operations
|
|
* full-text-search with Tantivy
|
|
* realistically, you need this as soon as you can start adding data to it
|
|
|
|
After that, it will be a focus on the front end, and possibly a Flutter/Dart app for mobile. For the
|
|
web client, I'm leaning toward something like [HTMx](https://htmx.org/docs/#introduction) but am not
|
|
against other lightweight javascript solutions.
|
|
|
|
And finally, things like commandline tools to do things like reset passwords or delete accounts, or
|
|
otherwise interact with the database outside of the main app. And then, OAuth or OIDC support. Down
|
|
the line, I want to experiment with implementing
|
|
[Backchannel](https://www.inkandswitch.com/backchannel/) for decentralized and social identity and
|
|
supporting that inside this. And way, way down the line, I might want to add ActivityPub for
|
|
fediverse compatibility.
