Pull request overview

Initial full-stack project scaffolding for a “Cheat Sheet” app, introducing a React (Vite) frontend, a Django REST backend, and Docker Compose workflow to run both services locally.

Changes:

Added Vite + React frontend with a simple health-check UI calling /api/health/.
Added Django + DRF backend with an /api/health/ endpoint and environment-driven settings.
Added Dockerfiles and a docker-compose.yml to build/run frontend + backend together.

frontend/package.json

+  "scripts": {
+    "dev": "vite",
+    "build": "vite build",
+    "lint": "eslint .",


npm run lint is defined, but there is no ESLint configuration file in the frontend (e.g., eslint.config.js for ESLint 9, or an .eslintrc*). As-is, eslint . will typically fail with "No ESLint configuration found". Add an ESLint config (and any needed parser/settings for React) or remove/adjust the lint script until configuration is in place.

Suggested change

"lint": "eslint .",

frontend/Dockerfile

+WORKDIR /app
+
+COPY package.json package-lock.json* ./
+RUN npm install


For deterministic container builds, prefer npm ci over npm install when a lockfile is present. npm ci is faster and ensures the container matches package-lock.json exactly.

Suggested change

RUN npm install

RUN npm ci

+    depends_on:


In Docker Compose, the frontend container cannot reach the backend at http://localhost:8000 (that points to the frontend container itself). Since vite.config.js defaults BACKEND_URL to localhost:8000, the /api proxy will fail under compose unless BACKEND_URL is set to something like http://backend:8000 for the frontend service (or the config detects Docker and uses the service name).

+ALLOWED_HOSTS = os.getenv("DJANGO_ALLOWED_HOSTS", "localhost,127.0.0.1,0.0.0.0").split(",")
+


ALLOWED_HOSTS is derived via .split(',') without trimming whitespace. If the env var contains spaces (common in .env files), Django will treat entries like ' localhost' as invalid hosts. Consider stripping each entry after splitting (and similarly for other comma-separated lists).

ALLOWED_HOSTS is split on commas without trimming whitespace. If DJANGO_ALLOWED_HOSTS contains spaces (common in .env files), entries like ' localhost' will be treated as invalid hosts. Consider stripping each host (and optionally filtering out empty strings) after splitting.

Suggested change

ALLOWED_HOSTS = os.getenv("DJANGO_ALLOWED_HOSTS", "localhost,127.0.0.1,0.0.0.0").split(",")

ALLOWED_HOSTS = [

host.strip()

for host in os.getenv("DJANGO_ALLOWED_HOSTS", "localhost,127.0.0.1,0.0.0.0").split(",")

if host.strip()

+REST_FRAMEWORK = {
+    "DEFAULT_PERMISSION_CLASSES": [
+        "rest_framework.permissions.AllowAny",
+    ],
+}


The REST_FRAMEWORK configuration uses AllowAny permissions globally, which means all API endpoints are publicly accessible without authentication. While this might be intentional for initial development, it should be documented or reconsidered before adding endpoints that should be protected. Consider adding a comment explaining this is for development only.
