docs(js): streamline React Router v6 and v7 documentation #13138

inventarSarah · 2025-03-27T07:56:00Z

DESCRIBE YOUR PR

Updated the React Router v6 and v7 documentation:

reduced the amount of alerts
reduced the amount of text at the top of the page to help users get to the first code snippet more quickly
- I did this by merging the content that was originally at the top into the sections below; this also allows us to rely on the code snippets provided to give needed information (e.g. we don't need to list the imports as they are included in the code)

Would it make sense to lead with something like this:

Suggested change

You can instrument your React Router v6 setup with Sentry. Depending on how you use react-router, slightly different setups are needed:

<TableOfContents ignoreIds={["custom-error-boundary", "next-steps"]} />

Additionally, make sure to [Setup a Custom Error Boundary](#custom-error-boundary) to ensure rendering errors are captured to Sentry.

and something similar for react-router v7 :)

@mydea Good point! I updated the start of the page with an adapted version of your suggestion.

Sadly, the TableOfContents component does not work with our structure as it seems to be created to work with the SDK options pages, and our structure here is quite different -> I created an issue #13159 so we can consider upgrading the functionality of this component

should be fixed here #13171 😅

the toc is now included - looks good!

+  need error boundaries to handle errors in event handlers.
 </Alert>

 To send errors to Sentry while using a custom error boundary, use the `Sentry.captureException` method:


Not related to any change in this PR but generally: We should clarify here, because it is not clear to me: What If I am not using a custom error boundary, what should I do then? Should I add one to capture errors, or not? cc @lforst & @AbhiPrasad

I think for react router you need to add one, otherwise component-related errors get swallowed by the router itself.

yeah, so let's reword this (can be a different PR as well) to make it clear you def should add this, not just if you're using a custom boundary!

I added a sentence to the first paragraph in this section (v6 and v7 pages) -- hope this is what you meant (if not, let's chat later today @mydea :) )

+Now, Sentry should generate `pageload`/`navigation` transactions with parameterized transaction names (for example, `/teams/:teamid/user/:userid`), where applicable. This is only needed at the top level of your app, unlike React Router v4/v5, which required wrapping every `<Route />` you wanted parametrized.

Is this section helpful? What does it tell me? 😅 I should set this up anyhow to get all errors, I'd say?

I mean this whole alert here!

Removed it vor v6 and v7 👍

+In production, these errors won't surface unless captured manually. If you **don't** have a custom error boundary in place, `react-router` will create a default one that "swallows" all errors.\
+Hence, to capture these errors with Sentry in production, we strongly recommend to implement a custom error boundary.

 <Alert>


Same as above, do we need this alert?
