Simple FastAPI app which logs incoming post requests.

The app returns HTTP code 202 'Accepted' and uses FastAPI's BackgroundTasks to asynchronously log the payload to the given file.

log_router took 0.000084 seconds to execute.
async_log took 0.003367 seconds to execute.

This speeds up performance as well as decoupling response times from the size of the logged payload.

Follow these steps to set up the project:

1. Install dependencies:

   pip install -r requirements.txt

2. Run the application:

   python app.py

After setting up, you can visit the /docs endpoint in your web browser to view the Swagger documentation for the API.

This application exposes a single API endpoint /v1/log which accepts POST requests.

This endpoint is used to log messages. The request body should be a JSON object with the following properties:

• file_name: The name of the log file to write to. It should be a string of maximum 20 characters, and should match the pattern ^[a-zA-Z0-9_-]+\\.log$. For example: "mylogfile.log".
• level: The level of the log message. It should be a string that matches the pattern ^(debug|info|warning|error|critical)$. For example: "info".
• context: The context of the log message. It should be a string of maximum 20 characters. For example: "foo".
• message: The log message. It should be a string of maximum 1000 characters. For example: "This is a log message".

All properties are required.

The endpoint responds with a status code of 202 if the log message was successfully processed. In case of a validation error, it responds with a status code of 422 and a JSON object describing the validation errors.
