Before First Request Flask - Latest Information & Updates 2026

Web Reference: Sep 1, 2022 · I'm learning web development for simple applications and I've created one that uses before_first_request decorator. According with the new release notes, the before_first_request is deprecated and will be removed from Flask 2.3: These functions will be called before the before_request() functions. The function can modify the values captured from the matched url before they are passed to the view. What are you using as a replacement now that `before_first_request` is deprecated? I used it to reconnect to the database when new uWSGI workers would be spawned (as they should not share the same database connection). But now I'm not sure how to accomplish this. Any advice would be appreciated.
