jdm-electron-flask 1.0.4

The Python backbone for jdm-electron-flask desktop apps

jdm-electron-flask (Python)

The Python backbone for jdm-electron-flask desktop apps.

This package ships inside every project scaffolded by the jdm-cli electron-flask plugin. It provides the app factory, dynamic API registration, SocketIO setup, and environment-aware logging — so you build features, not boilerplate.

---

Installation

You don't install this manually. It's included in the scaffolded requirements.txt:

jdm-electron-flask==1.0.0

If you need it standalone:

pip install jdm-electron-flask

What it provides

create_app

The Flask app factory. Handles config loading, SocketIO init, blueprint auto-discovery, and the React SPA catch-all route.

# run.py
from jdm_electron_flask import create_app, get_socketio

app = create_app()
socketio = get_socketio()

if __name__ == "__main__":
    socketio.run(app, host="0.0.0.0", port=5000, debug=True)

JDMBlueprint

Extended Blueprint with built-in response helpers.

from jdm_electron_flask import JDMBlueprint

health_bp = JDMBlueprint("health", __name__)

@health_bp.route("/health")
def health():
    return health_bp.success({"status": "ok"})

JDMEvents

Base class for organizing socket event handlers.

from jdm_electron_flask import JDMEvents

class ConnectEvents(JDMEvents):
    def register(self):
        @self.socketio.on("connect")
        def on_connect():
            self.on_connect()

        @self.socketio.on("ping_server")
        def on_ping(data):
            self.emit("pong_client", {"echo": data})

ConnectEvents().register()

Printer

Environment-aware logger. Prints in development, writes to logs/<date>.log in production/deployed.

from jdm_electron_flask import Printer

Printer.success("Blueprint registered")
Printer.warn("Something is off")
Printer.error("Something broke")
Printer.info("Just FYI")

Response helpers

from jdm_electron_flask import success, error, paginate

return success({"user": "JDM"})
return error("Not found", status=404)
return paginate(items, total=100, page=1, per_page=10)

Validators

from jdm_electron_flask import validate_fields

valid, msg, data = validate_fields(["name", "email"])
if not valid:
    return error(msg)

---

Dynamic API registration

Routes are controlled by config/api.json:

{
    "health": {
        "link": "/api",
        "masterEnabled": true
    },
    "users": {
        "link": "/api/users",
        "masterEnabled": true,
        "disabledOnProduction": false,
        "disabledOnDeployed": false
    }
}

Adding a new route:

1. Add entry to config/api.json
2. Create app/api/users.py with a users_bp blueprint

That's it. No touching __init__.py ever again.

---

Environment modes

FLASK_ENV	Behavior
development	Debug on, console logging, all routes enabled
production	Debug off, file logging, respects disabledOnProduction
deployed	Debug off, file logging, respects disabledOnDeployed

---

Companion

This package is the Python half of the jdm-electron-flask ecosystem:

Package	Role
jdm-electron-flask (npm)	CLI plugin — scaffold, build, compile
jdm-electron-flask (PyPI)	Backend library — app factory, blueprints, sockets
