1. Project Description

The WIN Student Goal Tracker is a web-based case management system designed to support organizations working with adults with special needs. The platform enables staff to track student goals, document services, and log critical incidents while maintaining strong privacy, auditability, and compliance with FERPA, IDEA, and FAPE.

The system is designed with sustainability in mind, ensuring that future developers can easily maintain, extend, and redeploy the application.

2. Architecture

Technology Stack & Infrastructure

Architecture Description

1. Presentation Layer (Angular)
2. Application Layer (.NET API)
3. Data Layer (MySQL)

Traefik manages routing and HTTPS traffic.

3. Data Flow

Each scenario lists the UI file that initiates the action, the Angular service method called, the API endpoint hit, the .NET controller and repository method invoked, and the stored procedure that reads or writes the database.

1 — User Login

2 — View My Students (Home Dashboard)

3 — Open Student Workspace (Full Profile)

4 — Create Goal

5 — Log Progress Event

4. Recommended Hosting

• The entire application is currently hosted online with Hetzner (www.hetzner.com), on a plan donated by team members. The team has committed to hosting for at least the next two years, and if/when that changes, will help the partner transition to the hosting platform of their choice.

5. Application Installation

The application is composed of three moving parts — an Angular 20 SPA (ui/winstudentgoaltracker), a .NET 9 Web API (api/), and a MySQL 8 database initialised from the SQL objects in db/Objects/. Configuration for every tier is read from a single .env file at the repository root. Two workflows are supported: running the stack directly on a developer workstation, or deploying the full stack to a server with docker compose behind an existing Traefik reverse proxy.

5.1 Local Development Environment

The recommended local workflow runs MySQL in Docker (so the schema initialises itself from db/docker-init/01-schema.sh) while the API and UI run on the host for fast iteration and debugging.

Prerequisites

• Node.js 22+ and npm — to run the Angular CLI
• .NET 9 SDK — to build and run the API
• Docker Desktop (or Docker Engine + Compose plugin) — to run MySQL
• Git — to clone the repository

Step 1 — Clone and create .env

Clone the repository and create a .env file at the project root. The API reads it via DotNetEnv (which traverses parent directories), the UI/API containers read it through docker-compose.yml's env_file directive, and the MySQL container consumes the MYSQL_* variables natively.

git clone <repo-url> WinStudentGoalTracker
cd WinStudentGoalTracker

Create .env with the following keys (replace the secrets before sharing or deploying):

# MySQL container bootstrap
MYSQL_ROOT_PASSWORD=change_me_root
MYSQL_DATABASE=winstudentgoaltracker
MYSQL_USER=appuser
MYSQL_PASSWORD=change_me_app

# Connection used by the .NET API
MYSQL_HOST=127.0.0.1
MYSQL_PORT=3309
# (the api falls back to root/no-password if MYSQL_USER/PASSWORD are omitted)

# JWT signing key — must be >= 32 bytes
JWT_KEY=replace_with_a_long_random_string_at_least_32_chars

.env is listed in .gitignore; never commit it. For local dev, point MYSQL_HOST at 127.0.0.1 so the host-side API can reach the containerised MySQL through the published port 3309.

Step 2 — Start MySQL

Bring up only the database service from the root compose file. On first run it creates the volume, creates the database and application user, and executes db/docker-init/01-schema.sh which loads tables, functions, views, and stored procedures from db/Objects/ in the correct order.

docker compose up -d mysql
docker compose logs -f mysql   # watch for "Schema initialization complete"

MySQL is exposed on host port 3309 (mapped to container port 3306). To reset the database during development, stop the container and remove the named volume: docker compose down && docker volume rm winstudentgoaltracker_win_mysql_data.

Step 3 — Run the API

cd api
dotnet restore
dotnet run

The API listens on http://localhost:5000 (and https://localhost:5001) by default via Kestrel. Swagger UI is available at /swagger when running in the Development environment (the default for dotnet run). On startup the console prints the resolved MySQL connection string — verify it points at 127.0.0.1:3309 and the database name from your .env.

Step 4 — Run the UI

cd ui/winstudentgoaltracker
npm install
npm start

The Angular dev server starts on http://localhost:4200. The base URL the UI calls is defined in src/environments/environment.development.ts. For a fully local stack, edit that file so apiBaseUrl points at your locally running API (e.g. http://localhost:5000) instead of the deployed https://winapi.opelly.me. The API's CORS policy already allows any origin in development.

Step 5 — Seed a user

The schema initialises empty. To sign in, insert at least one user, one school_district, one program, and a user_program row linking the user to the program with a role. Passwords are hashed with PBKDF2 by PasswordHasher; the simplest path is to use an existing seeded dump (ask a team member for seed.sql) or register via a super_admin account using the admin endpoints.

5.2 Production Deployment (Docker Compose + Traefik)

Production deploys all four tiers — MySQL, .NET API, Nginx-served Angular build, and the Traefik reverse proxy — as Docker containers on a single VPS. The repository's docker-compose.yml brings up MySQL, the API, and the UI; Traefik runs in a separate compose stack on the same host and publishes ports 80/443 for the whole server. The two stacks communicate through an external Docker network named web.

Prerequisites on the server

• Linux VPS with Docker Engine and the Compose plugin installed
• Ports 80 and 443 open on the server's firewall
• Two DNS A records pointing at the server's public IP: win.<your-domain> (UI) and winapi.<your-domain> (API)
• A working Traefik stack on the host (see next section)

Setting up Traefik (one-time)

Traefik is the edge router that terminates TLS, requests Let's Encrypt certificates, and forwards traffic to the correct container based on the Host() rule. The WIN compose file assumes Traefik is already running on the host and configured with:

• An external Docker network named web that Traefik is attached to. The application's UI and API containers join this network so Traefik can reach them.

  docker network create web

• An entrypoint named websecure listening on :443 (and typically a redirect from :80).
• A certificate resolver named letsencrypt (ACME, HTTP or DNS challenge) configured with an email and a persistent acme.json volume.
• Two file-provider middlewares referenced by the labels in docker-compose.yml: gzip@file (compression) and security-headers@file (HSTS, frame-deny, etc.).

A minimal Traefik docker-compose.yml typically lives in /opt/traefik/ alongside a traefik.yml static config (declaring the entrypoints, providers, and ACME resolver) and a dynamic/ directory containing the gzip and security-headers middleware definitions. Traefik's official documentation at doc.traefik.io covers this setup in detail — the WIN stack does not prescribe a specific Traefik configuration, it only requires that the network, entrypoint, cert resolver, and middleware names above exist.

Step 1 — Prepare the repository on the server

git clone <repo-url> /opt/winstudentgoaltracker
cd /opt/winstudentgoaltracker

Step 2 — Populate .env

Same keys as the local workflow, but with production-safe values. For the containerised deployment, MYSQL_HOST must be the service name mysql (the API container resolves it over the internal backend Docker network) and MYSQL_PORT must be 3306 (the container's internal port, not the host-mapped 3309):

MYSQL_ROOT_PASSWORD=<strong-random>
MYSQL_DATABASE=winstudentgoaltracker
MYSQL_USER=appuser
MYSQL_PASSWORD=<strong-random>
MYSQL_HOST=mysql
MYSQL_PORT=3306
JWT_KEY=<32+ byte random secret>

Step 3 — Update domain labels (if not using opelly.me)

docker-compose.yml hard-codes the Traefik Host() rules winapi.opelly.me and win.opelly.me. Edit those two labels to match your DNS records before bringing the stack up. The UI also points at https://winapi.opelly.me via src/environments/environment.ts; update that file and rebuild the UI image so the browser calls your API host.

Step 4 — Build and start the stack

docker compose up -d --build

This creates:

• winstudent-mysql — MySQL 8 on the internal backend network, volume win_mysql_data, schema loaded on first start.
• winstudent-api — .NET 9 API on port 8005, attached to both backend (to reach MySQL) and web (to be reached by Traefik). Published at winapi.<your-domain> over HTTPS.
• winstudent-ui — Angular build served by Nginx on port 8006, attached to web. Published at win.<your-domain> over HTTPS.

Traefik picks up the new containers automatically via its Docker provider, requests TLS certificates from Let's Encrypt on first request, and begins routing traffic. Confirm with docker compose ps (all services healthy/running) and docker compose logs -f api (look for the Kestrel startup line and the printed connection string).

Step 5 — Verify

• Visit https://win.<your-domain> — the login page should load over HTTPS with a valid Let's Encrypt certificate.
• Visit https://winapi.<your-domain>/swagger — should return 404 in production (Swagger is only enabled in Development); a 404 from the API itself confirms routing works.
• Sign in with a seeded user and check docker compose logs api for successful /api/Auth/Login requests.

Updating a running deployment

cd /opt/winstudentgoaltracker
git pull
docker compose up -d --build    # rebuilds changed images and recreates containers
docker compose logs -f

MySQL is not rebuilt by --build (it uses the upstream image) and its volume persists across up/down cycles, so data survives code deployments. Schema migrations should be applied by running the appropriate SQL files from db/migrations/ against the running MySQL container; see section 7 for backup procedures before running migrations.

6. Authentication & Authorization

JWT-based authentication with refresh tokens.

Key files: AuthController.cs, JwtService.cs, middleware

7. Database Backup

Backup

mysqldump -u username -p dbname > backup.sql

Restore

mysql -u username -p dbname < backup.sql

From the UI

Administrators may back up the database via the "Backup" button in the Administrator panel

8. Environment Variables

DB_CONNECTION=...
JWT_SECRET=...
JWT_EXPIRATION=3600

Ensure .env is in .gitignore.

9. Partner Statement

The partner representatives Polly Balsillie and Fred Winter have reviewed the developer documentation and understands its scope and purpose.
