Tips for troubleshooting and receiving error notifications when coding javascript/p5.js on Sublime text with a Flask backend

Currently, my web application project runs on a Flask backend within a virtual machine environment. I prefer using Sublime Text for coding, running Flask run command in the terminal, and accessing pages on http://127.0.0.1:5000/ via a web browser. Whenever there's an issue with the Flask backend, error messages pop up.

The hierarchy of my folders is structured as follows:

app.py
/templates
    index.html
/static
    /css
    /js
        my_js.js

Being relatively new to Flask and JavaScript, I'm uncertain about how to view error messages for debugging the code within my_js.js.

Answer №1

As I mentioned in my previous comment, it seems like you're searching for the developer tools in your web browser, particularly the JavaScript console.

Make sure to regularly check the JavaScript console for any errors that may arise. You can utilize console.log() statements to gather additional information, or even use the JavaScript debugger tool. Many developers tend to keep their JavaScript console open in a separate window while working.

Furthermore, the developer tools offer other functionalities such as inspecting HTML elements and analyzing network traffic. The best part is that you don't need to download anything extra - these features come built-in with every modern browser.

If you want more insights, I suggest searching for "chrome developer tools" or "firefox developer tools" based on the browser you are using. Here are some recommended resources to kickstart your journey:

You might also have the option to debug JavaScript directly from Sublime Text. While I'm not an expert in this area, starting with your browser's developer tools would be a good approach. Best of luck!
