destroying_sap
A fullstack SaaS web application built with FastAPI, React, and PostgreSQL.
Stack
| Layer | Tech |
|---|---|
| Backend | FastAPI (async), SQLAlchemy 2, Alembic, PostgreSQL 16 |
| Auth | JWT bearer tokens, bcrypt password hashing |
| Frontend | React 18, TypeScript, Vite, React Router v6, TanStack Query |
Current State
- User registration and login (JWT auth)
- Protected dashboard route
/api/users/me— authenticated user info- 3 separate Docker containers:
db(PostgreSQL),backend(FastAPI),frontend(nginx) - Dev environment seeds a test user automatically on startup (
test@example.com/Test123!) - Password policy: min 8 chars, upper + lowercase, digit, special character, no common words
- Pre-commit security hook (
scripts/security_check.py) runs inside Docker on every commit
Containers
| Container | Image | Port | Description |
|---|---|---|---|
db |
postgres:16-alpine | 5432 | PostgreSQL database |
backend |
custom (python:3.12-slim) | 8000 | FastAPI management API |
frontend |
custom (nginx:alpine) | 80 | React UI served by nginx |
The frontend nginx container proxies /api/* to the backend container internally — no CORS headers needed in production.
