How to Test

git clone https://github.com/huntingcodes-001/openai-chat-app-quickstart.git
cd openai-chat-app-quickstart
pip install -r requirements.txt

• Test the code

1. Run the application using the command: `python app.py`
2. Verify that all features work as expected on both Windows and Linux environments.
3. Check for successful installation of all required dependencies without errors.

What to Check

Verify that the following are valid -All dependencies are installed without issues on both Windows and Linux systems. -The application runs smoothly and all functionalities are intact after the changes.

Other Information

Ensure that the development environment reflects the changes made in this PR. It may be helpful to run the tests on both operating systems to verify compatibility.

Thanks @huntingcodes-001 for the PR. The requirements.txt file is generated by this command: pip-compile --output-file=requirements.txt pyproject.toml

Will that retain the marker for the windows OS, or will it override when we run -U? I thought it would override.

[pamelafox]

The other option:

requirements.in could bring in just uvicorn, not uvicorn[standard], and then bring in uvloop with the environment marker you have in this PR.

Here's what standard brings in: https://github.com/encode/uvicorn/blob/6ffaaf7c2f78274889da1572832dd307a8b117d3/pyproject.toml#L39

[huntingcodes-001]

You're correct that using pip-compile to regenerate the requirements.txt file will override any manual modifications, including the OS markers.

To ensure that the requirements are preserved for both Windows and Linux, we can consider adding a comment in the requirements.in file, indicating that the OS-specific installations should remain intact. Alternatively, we could explore using separate requirement files for different platforms if that fits better with our workflow.

[huntingcodes-001]

Bringing in just uvicorn in requirements.in and specifying uvloop with an environment marker sounds like a solid approach. This would allow us to keep the installation lean while still accommodating the platform-specific needs.

[pamelafox]

Okay, so if we bring in just uvicorn, not uvicorn[standard], plus uvloop with a marker, we also need to decide whether to bring in the other packages from [standard]:

• "colorama>=0.4;sys_platform == 'win32'": This just adds colored logs, and we don't use it now for Windows users, so we can keep not using it.
• "httptools>=0.5.0": I think we want this, it seems like httptools is recommended from my read of the codebase.
• "python-dotenv>=0.13": We already bring this in, so we don't need to bring it in again
• "PyYAML>=5.1": I don't think we need this, since we're not using a YAML to configure uvicorn
• "watchfiles>=0.13": This is helpful for using --reload, so we want this
• "websockets>=10.4": I don't think we need this, since our app doesn't currently use websockets.

In conclusion, we want:

• uvicorn
• uvloop with marker
• httptools
• watchfiles

[huntingcodes-001]

Thanks for breaking that down!

Based on your suggestions, I’ll update the requirements.in to include the following:

uvicorn without [standard] uvloop with the platform-specific marker httptools (since it’s recommended) watchfiles (for --reload functionality) I'll leave out colorama, PyYAML, and websockets as discussed. This should keep the dependencies lean while ensuring the necessary functionality remains intact.

[pamelafox]

Sounds good, thanks!

I just merged the fix that I suggested, so am closing this, thanks for sending the PR in!
