The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.
Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Only the gzipped size is provided here based on an expert tip.
First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.
Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis
Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 10% or more, there will be a red status indicator applied, indicating that special attention should be given to this.

Overview
Update: The base branch is
v19since these are React 19 specificNote: this is included in one PR to minimize the number of conflicts with the translation repos.
Now that the React 19 beta is out, the callouts on the page can be converted to specify "React 19 beta" for the features that are in React 19. I also switched the React Server Components callouts to it's own callout type, since the important notice there is not the specific release but the environment they run in.
Included in this PR:
<NextMajor>and<RSC> callout components, similar to the` callout.<NextMajorBadge>and<RSCBadge>components, similar to<CanaryBadge>canarywith an enumcanary | majorReact 19badges to sidebar itemsNote on the text: the text says "available in React 19 beta and the React canary channel". This is so users who are using the canary with these features today will not be confused and think they're not available in their release. We can drop the "React canary channel" part once we ship the pinned version for react 18, but it's probably better to keep it until the stable release so we don't churn external links.
