This Repository gives a brief idea of how you can package a FastAPI program as a standalone executable.
To get started, fork this repository and add an endpoint-decorator to the tutorial.py file.
In order to get an executable, you need to run the github workflow, which is already included in the repository, and as such also in your fork.
To run the workflow, you need to push a tag to the repo.
You may do that by first creating a tag on a certain commit and then push that:
user@machine ~/r/f/app (master)> git tag v0.1.5
user@machine ~/r/f/app (master)> git push --tags
Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
To github.com:skunkforce/fastapi-exe-tutorial.git
* [new tag] v0.1.5 -> v0.1.5
The workflow will take the FastAPI program and use the tool pyinstaller in a github-action to create a release, containing a .zip for Windows and .tar.gz for Linux.
When the workflow has finished, download this release and unzip it into a directory of your choice.
Use the Windows-CMD to navigate into the chosen directory and run it by typing .\tutorial.exe.
FastAPI will launch a server on your loopback-IP device and will claim port 8000 by default.
If you'd like to change the port, or even expose your server into your local network, you may change the line uvicorn.run(app, host="127.0.0.1", port=8000) to a different port, respectively to the IP 0.0.0.0, since 127.0.0.1 only exposes the port to your own loopback, making the service only available from the very device you are running it on.
In a later commit, handling of commandline arguments was added.
Please run the executable with --help to find out how to use the options.
Have Fun!
