Setup

Prerequisites

Make sure you have the following installed:

• Python 3.x
• pip

Installation

1. Clone the repository:

git clone git@github.com:HackerSchool/HS-API.git
cd HS-API

2. Create a virtual environment:

python -m venv .venv
source .venv/bin/activate

3. Install dependencies:

pip install -r requirements.txt

4. Setup environment variables: Create a .env file and add any necessary environment variables (see Environment Variables section).

5. Setup the database and create an admin user:

flask db upgrade 
flask create-admin

6. Run the application:

flask run --debug

Environment Variables

TLDR: You can just cp .env.example .env to get all default environment variables ready.

• SESSION_DIR: Where to store session files (defaults to data/flask_sessions/)

• SESSION_LIFETIME: How long a session should last in seconds (defaults to 3 hours)

• DATABASE_PATH: Path to the sqlite3 database file (defaults to data/db/hackerschool.sqlite3)

• STATIC_DIR: Path to the folder where user and project images will be stored (defaults to data/static/)

• ROLES_PATH: Path to the roles configuration json file (defaults to data/roles.json)

• LOGS_PATH Path to logs file (defaults to stdout)

• FRONTEND_URI URI for the frontend (defaults to http://localhost:3000 for dev)

These will only be necessary if you'll be using the flask create-admin command

• ADMIN_USERNAME: Admin username
• ADMIN_PASSWORD: Admin password

Project Structure

The project follows a layered architecture with a controller, service and models layer.

+-------------+
|  Controller |
+-------------+
       ^
       |
       |
+-------------+
|   Service   |
+-------------+
     ^    ^
     |    |
     |    +---------------------+
     |                          |
+-------------+        +------------------+
|   Models    |        |  Other Handlers  | (e.g, logos handler in filesystem)
+-------------+        +------------------+

The structure is based on the Flask factory extension pattern.
