# Stick Stick is a high-fidelity Rust web application starter template built on Axum, Askama, and MongoDB. Unlike traditional MVC frameworks that segment code horizontally by technical layers (controllers, models, views), Stick is organized by **vertical slices**. Each domain feature—such as authentication, tasks, or audit logging—lives together in its own self-contained module. This simplifies code maintenance and cognitive load in medium-to-large codebases where horizontal layers inevitably grow difficult to navigate. --- ## Architectural Philosophy & Layout ### 1. Vertical Slice Domain Layout Every domain feature owns its database access models, business logic, endpoints, and markup templates. For example: * `src/auth/models.rs`: BSON data structures and claims. * `src/auth/repository.rs`: Database operations and query logic. * `src/auth/handlers.rs`: Request/response lifecycle logic. * `src/auth/extractors.rs`: Axum extractors for user session handling. * `templates/auth/`: HTML templates compiled at build-time. ### 2. Separating Components from Documentation To prevent domain pollution and maintain code integrity, we strictly separate template assets: * **Reusable UI Components** (`templates/components/`): Reserved strictly for operational UI blocks used across the application. Reusable elements like fields, dropdowns, calendars, and buttons are defined as Askama macros inside [templates/components/macros.html](templates/components/macros.html). * **System Documentation** (`templates/docs/` & `src/docs/`): Design manuals, guidelines, and interactive preview sandboxes are isolated. The Documentation portal is served on a dedicated `/docs` route, separate from core application logic. ### 3. Key Stack Decisions * **Axum (v0.8)**: Modern, async-first routing and middleware. * **Askama (v0.16)**: Evaluates and compiles HTML templates into Rust code at compile time. Syntax, variable existence, and type constraints are verified by the compiler. * **MongoDB**: Standard Rust driver configured with BSON serialization. * **Tailwind CSS**: Utility-first styling compiled using a Node-based wrapper process. * **JWT Authentication**: Managed via JSON Web Tokens stored in secure, encrypted `HttpOnly` cookies. --- ## Audit Logging Framework (First-Class Feature) Stick contains a built-in, request-scoped **Audit Logging and Replay** framework designed to make all critical system mutations (Create, Read, Update, Delete, Search) auditable. ``` Request │ ▼ ┌──────────────────┐ │ AuditLogger │ ──► Resolves: DB, User, User-Agent │ Extractor │ └──────────────────┘ │ ├──► Parses "x-forwarded-for" & "x-real-ip" proxy headers ├──► Parses Direct ConnectInfo TCP socket IP │ ▼ ┌──────────────────┐ │ Log Entry Writ │ ──► Formats: "ProxyIP (Socket: SocketIP)" if mismatched └──────────────────┘ │ ▼ ┌──────────────────┐ │ MongoDB Store │ ──► Stores structured entry + JSON state snapshot └──────────────────┘ ``` ### 1. Request-Scoped Extractor (`AuditLogger`) The custom `AuditLogger` extractor implements Axum's `FromRequestParts` trait. When added to any handler function signature, it automatically resolves: * Database connection reference. * Optional authenticated user context. * Client metadata (IP address and User-Agent). ### 2. Intelligent IP & Proxy Resolution To support load-balanced or proxied environments, the extractor resolves and logs both network paths: - Inspects standard proxy headers (`x-forwarded-for`, `x-real-ip`). - Captures the direct TCP client connection address via Axum's `ConnectInfo`. - If the proxy IP and connecting socket IP differ, the logger combines them (e.g. `10.0.0.1 (Socket: 127.0.0.1)`) ensuring full visibility of both the request origin and proxy hop. ### 3. Historical State Snapshotting (Replayability) Log entries include a serialized JSON `payload` field containing the state of the affected entity. For edits, it saves the state transition. For deletions, it saves the final snapshot before removal, ensuring data remains reconstructible in the event of an audit inquiry. ### 4. Admin Audit Panel Authorized administrators can review, search, and audit system activities at `/auth/audit`. The dashboard allows filtering entries by: * **Username**: Filter logs to a specific actor. * **Event Type**: Filter by actions (e.g. `Login`, `Create`, `Update`, `Delete`). * **Entity Type & ID**: Pinpoint history for a specific resource (e.g. `Task`, `Developer`). * **Timeline**: Filter logs by start and end timestamps. --- ## Core Features Included ### Self-Provisioning Administrator On startup, if the MongoDB `users` collection is empty, Stick automatically provisions an administrator account with username `admin`, generates a secure random 16-character alphanumeric password, and outputs the credentials directly to the console logs: ```text ====================================================== CREATED INITIAL ADMINISTRATOR ACCOUNT: Username: admin Password: [GeneratedPassword] ====================================================== ``` ### User Management Panel (Admin Only) Accessible at `/auth/users`. Administrators can view all users, register new ones, toggle administrative roles, reset passwords, or delete standard accounts (with safety blocks preventing administrators from deleting their own active profile or revoking their own privileges). ### Self-Service Password Reset Any logged-in user can change their password at `/auth/password` by clicking their username in the navigation bar. --- ## Setup and Running ### Prerequisites * **Rust**: Toolchain v1.75+ (for native async traits). * **Node.js & npm**: Required to build Tailwind CSS. * **MongoDB**: Running locally on `mongodb://127.0.0.1:27017`. ### Local Setup 1. Copy the environment configuration: ```bash cp .env.example .env ``` 2. Build Tailwind CSS styling: ```bash npm install npx tailwindcss -i src/input.css -o static/tailwind.css ``` 3. Run the development server: ```bash cargo run ``` The server will start listening at `http://127.0.0.1:3009` (as configured in `.env`). ### Running with Docker A multi-stage `Dockerfile` compiles Tailwind, compiles the Rust binary, and bundle a lightweight Debian runtime container. 1. Build the image: ```bash docker build -t stick . ``` 2. Start the container: ```bash docker run --name stick-app --rm --network="host" \ -e DATABASE_URL="mongodb://127.0.0.1:27017" \ -e DATABASE_NAME="stick_db" \ -e JWT_SECRET="super_secret_template_signing_key_that_is_at_least_32_characters_long" \ -e HOST="127.0.0.1" \ -e PORT="3009" \ stick ``` --- ## Developer Cookbook ### 1. Adding a Feature Slice (e.g. `projects`) 1. Create a module folder: `src/projects/`. 2. Define models in `models.rs` and database access operations in `repository.rs`. 3. Add request handlers in `handlers.rs`. 4. Create `src/projects/mod.rs` to expose the router: ```rust pub fn router() -> Router where crate::common::config::Config: axum::extract::FromRef, mongodb::Database: axum::extract::FromRef, S: Clone + Send + Sync + 'static, { Router::new() .route("/projects", get(handlers::get_projects)) } ``` 5. Place HTML templates under `templates/projects/` extending the `base.html` layout. 6. Register the module in `src/main.rs` and merge the sub-router: ```rust let app = Router::new() .merge(main_view::router()) .merge(auth::router()) .merge(projects::router()) // Merge domain router .with_state(state); ``` ### 2. Logging Operations with `AuditLogger` To log any action in a handler, inject `logger: AuditLogger` and invoke `.log()` after a successful DB mutation: ```rust use crate::audit::AuditLogger; use serde_json::json; pub async fn delete_task_handler( State(repo): State, logger: AuditLogger, // <-- Automatically injected Path(task_id): Path, ) -> Result { // 1. Fetch task and perform mutation let task = repo.get_by_id(&task_id).await?; repo.delete(&task_id).await?; // 2. Audit the event (single line, fully context-aware) logger.log( "Delete", // Event action "Task", // Entity type Some(task_id), // Target entity ID Some(format!("Deleted task '{}'", task.title)), // Description Some(json!(task)), // Serialized payload for replayability ).await; Ok(Redirect::to("/tasks")) } ``` --- ## Production Deployment to a Cloud Host (DigitalOcean Droplet) For production deployments (such as to a DigitalOcean Droplet), we avoid using `--network="host"`. Instead, we deploy both the database and the application container to a shared, user-defined Docker bridge network named **`dockernet`**. This provides secure internal DNS resolution and container isolation. ### 1. Create the Isolated Docker Network On your Droplet, create the bridge network: ```bash docker network create dockernet ``` ### 2. Build and Run the Database Infrastructure Build the custom MongoDB infrastructure image using the dedicated `Infra.DockerFile`: ```bash # 1. Build the database image docker build -t stick-db -f Infra.DockerFile . # 2. Run the database container on 'dockernet' with host persistence docker run --name stick-mongodb \ --network dockernet \ -v /var/lib/mongodb/data:/data/db \ -d \ stick-db ``` *Note: The database container is named `stick-mongodb`. Other containers on `dockernet` can now resolve this container using `mongodb://stick-mongodb:27017`.* ### 3. Build and Deploy the Application Container Build the main application image and launch it on the same network: ```bash # 1. Build the application image docker build -t stick-app . # 2. Run the application container, linking to the database using its container name docker run --name stick-app-container \ --network dockernet \ -p 80:3007 \ -e DATABASE_URL="mongodb://stick-mongodb:27017" \ -e DATABASE_NAME="stick_db" \ -e JWT_SECRET="your_secure_production_jwt_signing_key_at_least_32_chars_long" \ -e HOST="0.0.0.0" \ -e PORT="3007" \ -d \ stick-app ``` *Note: `-p 80:3007` maps the Droplet's external HTTP port 80 to the application's internal container port 3007.*
