⏳[ROADMAP] Medium Post: Building Real-Time Stock Monitors

[nexconnectio]

I want to share how PynneX can help you build real-world applications by walking through two examples I’ve worked on: a stock monitor console and a stock monitor UI. Along the way, I’ll also explain some key asyncio concepts, especially for those who might not be familiar with it yet. My goal is to show how PynneX simplifies tricky problems like managing threads and async workflows.

Here’s the general idea for the post:

---

1. Starting Simple with PynneX

I’ll start by introducing PynneX and why I built it. Handling thread-safe communication with signals and slots can feel complicated, but PynneX makes it straightforward. To show this in action, I’ll use a stock monitor example.

---

2. The Console Stock Monitor

This example is about building a real-time stock monitor where users interact through the console. It’s a fun project that highlights how PynneX handles two tricky tasks:

1. Keeping the main thread responsive to user input.

2. Running a worker thread that continuously updates stock prices.

I’ll focus on:

How signals and slots connect user inputs (like commands) to the backend logic.

How PynneX avoids the chaos of manual thread management or callback hell.

A few key code snippets that show how it all comes together.

3. Moving to a UI

Next, I’ll show how the same stock monitor logic can be extended to a GUI. Here’s where PynneX shines—its thread-safe design means you don’t have to worry about breaking your UI when background threads update data.

In this part, I’ll talk about:

Updating the UI in real time using PynneX’s signal-slot system.

Why decoupling the backend logic from the UI layer makes life easier.

Some code snippets to illustrate the process.

4. Making Sense of asyncio

I’ll also take some time to explain asyncio concepts as we go through these examples. If you’ve ever felt unsure about how async and await work, this part will break it down:

Why asyncio is perfect for real-time systems.

How PynneX uses asyncio to manage async tasks and event loops.

Common pitfalls and how PynneX helps you avoid them.

---

5. Wrapping It Up

I’ll finish the post with a quick summary of how PynneX can make multithreading and async workflows much more manageable. I also want to tease some future ideas, like integrating PynneX with Pub/Sub or Django, to spark interest and encourage contributions.

Why This Post?

I want to show how PynneX works in practical scenarios and make asyncio less intimidating. The stock monitor examples are great for this—they’re small enough to understand quickly but rich enough to highlight the challenges PynneX solves.

Let me know if you have thoughts or suggestions. I’m excited to share this with the community!
