rmorse / react-router-dom-v.6.02.prompt.blocker.js
Last active December 21, 2023 04:22
Adds back in `useBlocker` and `usePrompt` to `react-router-dom` version 6.0.2 (they removed after the 6.0.0 beta, temporarily)
/**
* These hooks re-implement the now removed useBlocker and usePrompt hooks in 'react-router-dom'.
* Thanks for the idea @piecyk https://github.com/remix-run/react-router/issues/8139#issuecomment-953816315
* Source: https://github.com/remix-run/react-router/commit/256cad70d3fd4500b1abcfea66f3ee622fb90874#diff-b60f1a2d4276b2a605c05e19816634111de2e8a4186fe9dd7de8e344b65ed4d3L344-L381
