QueryFlattenMiddleware for FastAPI

QueryFlattenMiddleware is a custom middleware for FastAPI applications that flattens query parameters separated by a specified delimiter. This is particularly useful for endpoints that need to handle multiple values for the same query parameter without using the standard array format.

Features

• Customizable Delimiter: Easily configure the delimiter used for splitting query parameter values.
• Seamless Integration: Works as middleware within any FastAPI application.
• Efficient Query Handling: Simplifies the process of handling multiple query parameters by flattening them, making endpoint logic cleaner and more straightforward.

Requirements

• Python 3.8.1+
• FastAPI

Installation

To install QueryFlattenMiddleware, you can use pip:

pip install fastapi-query-flatten

Usage

To use QueryFlattenMiddleware in your FastAPI application, simply add it as middleware in your app instance. Specify the delimiter you want to use for splitting query parameter values. The default delimiter is a comma (,).

Example

from fastapi import FastAPI
from fastapi_query_flatten import QueryFlattenMiddleware

app = FastAPI()

# Add QueryFlattenMiddleware with a custom delimiter
app.add_middleware(QueryFlattenMiddleware, delimiter=",")

With the middleware in place, a request to /items/?filter=value1,value2,value3 will be processed as if it were /items/?filter=value1&filter=value2&filter=value3, allowing the filter query parameter to be easily handled as multiple values.
