shopyo

Modular Flask framework for building scalable, maintainable web apps with isolated modules, event-driven communication, CLI tools, and built-in auth and data...

Shopyo Skill

Shopyo is a modular Flask framework designed for maintainability, extensibility, and real-world scale.

Project Structure

A typical Shopyo project:

text

/project_root
├── app.py          # Entry point, defines create_app()
├── init.py         # Extension initializer (db, login_manager, etc.)
├── manage.py       # CLI entry point
├── config.py       # Profile-based configuration
└── modules/        # Modular code
    ├── box__default/
    │   ├── auth/
    │   └── settings/
    └── my_custom_module/

CLI Commands

bash

# Environment setup
export SHOPYO_CONFIG_PROFILE=development
export FLASK_ENV=development
export FLASK_APP=app.py

# New project
shopyo new myproject --demo
cd myproject
shopyo initialise

# Create module
shopyo startapp modulename [boxname]

# Create box
shopyo startbox box__name

# Run server
shopyo run
flask run --debug

# Database
shopyo initialise   # Fresh start (creates db, migrations, default users)
shopyo db migrate
shopyo db upgrade
shopyo clean        # Reset local database

# Static files
shopyo collectstatic [module_path]  # Collect static files from modules

# Other
shopyo routes       # Show all routes
shopyo audit        # Find project issues
shopyo rename old_name new_name  # Rename module

Creating a Module

bash

shopyo startapp blog
# or with box
shopyo startapp blog box__ecommerce

Creates:

text

modules/blog/
├── __init__.py
├── forms.py
├── global.py
├── info.json
├── models.py
├── view.py

├── templates/

info.json Structure

json

{
   "author": {"mail": "", "name": "", "website": ""},
   "display_string": "Page",
   "module_name": "page",
   "type": "show",
   "fa-icon": "fa fa-store",
   "url_prefix": "/page",
   "dashboard": "/dashboard"
}

Module View Pattern

python

from shopyo.api.module import ModuleHelp

mhelp = ModuleHelp(__file__, __name__)
blueprint = mhelp.blueprint

@blueprint.route("/")
def index():
    context = mhelp.context()
    context.update({'message': 'Hello'})
    return mhelp.render('index.html', **context)

Models Pattern

python

from init import db
from shopyo.api.models import PkModel

class MyModel(PkModel):
    __tablename__ = 'mymodel'
    name = db.Column(db.String(100))

Templates

Extend the base template:

html

{% extends "shopyo_base/main_base.html" %}
{% block content %}
<h1>Hello</h1>
{% endblock %}

Use yo_render:

python

from shopyo.api.templates import yo_render

@blueprint.route("/demo")
def demo():
    return yo_render('blog/demo.html', {'key': 'value'})

Shopyo API

Key imports:

python

from shopyo.api.module import ModuleHelp, get_module, dispatch
from shopyo.api.models import PkModel
from shopyo.api.templates import yo_render
from shopyo.api.database import db
from shopyo.api.enhance import enhance_html

Inter-Module Communication

Use the event system:

python

from shopyo.api.module import dispatch

# Dispatch event
dispatch("user:registered", {"email": user.email})

# Listen for event
@dispatch("user:registered")
def send_welcome_email(email):
    pass

Testing

bash

pytest
pytest -v
pytest path/to/test.py
pytest --cov=shopyo
tox

Global.py Pattern

python

available_everywhere = {"x": 1}

configs = {
    "development": {"CONFIG_VAR": "DEVVALUE"},
    "production": {"CONFIG_VAR": "PRODVALUE"},
    "testing": {"CONFIG_VAR": "TESTVALUE"}
}

Default Credentials

After shopyo initialise:

• URL: http://localhost:5000
• Login: http://localhost:5000/auth/login
• Email: [e-mail]
• Password: pass

Key Conventions

• Box folders must start with box__
• Modules are isolated - do not import between modules directly
• Use event system (dispatch) for inter-module communication
• Run shopyo initialise after adding/removing modules
• Static files are collected into static/modules/ - don't edit directly
• Use shopyo clean to reset local development database
