AppScriptify CLI — create app templates instantly

AppScriptify — Login template (simple)

This small project provides a basic login/signup template using Flask and MongoDB (via Motor). It stores users in a MongoDB collection and uses secure password hashing (PBKDF2). The login can accept either username or email.

What it uses

• Flask — web framework
• Motor (async MongoDB driver) — async access to MongoDB
• python-dotenv — load environment variables

Files of interest

• appscriptify/appscriptify/templates/login/app.py — main Flask app used in this template
• appscriptify/appscriptify/templates/login/database.py — async database helpers (Motor)
• config.json — contains database/collection names (already present in the repo)
• templates/ and static/ — UI HTML/CSS/JS

Environment variables

Create a .env file in the project root with at least:

MONGO_URI="your_mongo_connection_string"

Example .env content:

MONGO_URI="mongodb+srv://testuser:<password>@testdb.ktuizkl.mongodb.net/?appName=TestDB"

Also ensure config.json (already present) contains the database and collection names. Example values are:

{
  "users_database": "usersDB",
  "users_collection": "users"
}

Change config.json if needed.

Install

1. (Optional) Create a virtual environment:

python -m venv .venv
.\.venv\Scripts\activate

2. Install dependencies:

python -m pip install -r requirements.txt

Run (development)

Open a terminal and run the Flask app file used in the template. From the repository root you can run:

python app.py

This will start Flask's built-in server on http://127.0.0.1:5000 by default.

Alternatively, you can set FLASK_APP and use flask run after setting the working directory appropriately.

Cookies & Sessions

• The app sets HTTP-only cookies for username/email by default (good for preventing JavaScript access).
• In development the cookie secure flag is set to False to allow non-HTTPS testing. In production change it to True.
• The app also stores minimal session info using Flask's session (server-side cookie signing). Make sure app.secret_key is set in production using an environment variable.

Notes and security

• Passwords are hashed with PBKDF2 + SHA256 via Python's hashlib and stored as base64(salt + hash). This is reasonably secure for a small project but using a well-maintained library (like passlib) is recommended for production.
• Motor is async; the example app uses a single event loop and runs async DB calls from synchronous routes. For production consider using an async-capable web server/framework (Quart/FastAPI) or rewrite routes as fully sync using pymongo.
• Make sure your MongoDB connection string is secure and credentials are not committed to the repo.

Next steps (suggested)

• Add a /logout route that clears cookies and session (I can add that for you).
• Add CSRF protection (e.g., Flask-WTF or a middleware) for forms.
• Replace manual cookie handling with Flask's session-related features or a secure server-side session store.
• Add tests for signup/login flows.
