It solves the problem of allowing web browsers to make cross-origin requests to your server by handling the browser's same-origin policy restrictions through proper HTTP headers and preflight request handling. The library lets you configure which origins can access specific routes, whether credentials are allowed, which headers clients can send, and which headers the server exposes back to clients.\n\nYou configure CORS per route by wrapping resources and routes through the library's API, specifying allowed origins and their associated options. The package handles both simple requests (which include the Origin header) and preflight requests (OPTIONS method queries that browsers send before complex requests). It supports wildcard origins for permissive configurations and per-origin customization for fine-grained control.","worth_installing":"Yes, if you are building an aiohttp application that needs to serve cross-origin requests from browsers. The package has low install friction, active maintenance, permissive licensing, and no known vulnerabilities. The Alpha status reflects the library's maturity rather than instability\u2014it has been in use since 2015. Install it when you need CORS support; skip it if your API is same-origin only or uses alternative cross-origin strategies."},"id":"aiohttp-cors","links":{"html":"https://skillfed.io/packages/aiohttp-cors","md":"https://skillfed.io/packages/aiohttp-cors.md","pypi":"https://pypi.org/project/aiohttp-cors/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-03-31","license_spdx":null,"license_treatment":"permissive","name":"aiohttp-cors","python_support":"supports_current","summary":"CORS support for aiohttp"},"popularity":{"monthly_downloads":19173377,"position":1072,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.8.1"}
