If a request arrives without one, the middleware generates a UUID v4 and adds it; if one exists but lacks a UUID v4 value, the middleware appends one. This enables request tracing across microservices, load balancers, and reverse proxies\u2014critical for correlating log entries and debugging distributed systems.\n\nThe middleware integrates directly into Flask's request handling with no required configuration. It exposes the current request ID via the request environment (HTTP_X_REQUEST_ID) so your application code can access it for logging or forwarding. You can optionally set a REQUEST_ID_UNIQUE_VALUE_PREFIX config to treat certain prefixed IDs as already unique, preventing unnecessary appends. The package is minimal and stable but unmaintained since 2019.","worth_installing":"Yes, if you need a minimal, zero-configuration request ID middleware for a Flask application and can accept that the package is unmaintained. It has no known vulnerabilities, low install friction, and a simple, stable API. No, if you require active maintenance, support for recent Flask versions, or a more feature-rich tracing solution. Verify the Open Government Licence v3.0 is acceptable for your use case."},"id":"flask-request-id-header","links":{"html":"https://skillfed.io/packages/flask-request-id-header","md":"https://skillfed.io/packages/flask-request-id-header.md","pypi":"https://pypi.org/project/flask-request-id-header/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2019-03-02","license_spdx":null,"license_treatment":"unclear","name":"flask-request-id-header","python_support":"unspecified","summary":"Python Flask middleware to ensure all requests have a request ID header"},"popularity":{"monthly_downloads":101696,"position":12921,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.1.1"}
