generatePath changed behavior v6

[brunouber]

Reproduction

I'm trying to upgrade react-router-dom from 6.4.2 to 6.30.1 (latest of branch v6).

In version 6.4.2:

import { generatePath } from 'react-router-dom';

generatePath("/book/:id.json", { id: 42 }); 
// /book/42.json

In version 6.30.1

import { generatePath } from 'react-router-dom';

generatePath("/book/:id.json", { id: 42 }); 
// /book/:id.json

Is it possible to go back on the original behavior?

System Info

node.js v22.12.0, but it shouldn't matter.

Used Package Manager

npm

Expected Behavior

import { generatePath } from 'react-router-dom';

generatePath("/book/:id.json", { id: 42 }); 
// /book/42.json

Actual Behavior

import { generatePath } from 'react-router-dom';

generatePath("/book/:id.json", { id: 42 }); 
// /book/:id.json

[github-actions]

To align with our new Open Governance model, we are now requiring that all issues have a minimal and runnable reproduction. To that end, we're doing some housekeeping in the repo to clean up existing issues that do not have a valid reproduction. This should get us down to a more manageable number of issues and allow us to be more responsive to existing and newly filed issues.

We're using a GitHub actions script to identify issues without a reproduction by looking for a StackBlitz, CodeSandbox, or GitHub link in the issue body. This won't be perfect, so if this issue has a reproduction on another platform, please comment back on here, and we can re-open the issue. Similarly, if there's a reproduction buried in a comment, please move the link into the description and comment back. Please tag @brophdawg11 or @brookslybrand in your comment so we get a notification as well 🙂.

If this issue did not have a reproduction but is still valid, or if you wish to start with a fresh issue, please create a new issue with a fresh reproduction against v7 and link to this issue in the new description.

If this is a feature request, please open a new Proposal Discussion in React Router, and if it gets enough community support, it can be considered for implementation.

If you have any questions, you can always reach out on Discord. Thanks again for providing feedback and helping us make React Router even better!
