Nice! I ended up with the same decision for RTK 2.0. That said, I also replaced it with ESM builds that were pre-compiled to target the browser. How'd you end up deciding to drop UMD, and is there going to be an ESM-format replacement at all? |

The recommendation is to use esm.sh for demos. In fact, we should update our fixtures that use UMD: https://github.com/facebook/react/blob/main/fixtures/flight-browser/index.html#L19-L23 To use the esm.sh versions like this: https://github.com/facebook/react/blob/main/fixtures/flight-esm/server/global.js#L91-L95 (It does mean that it won't use local builds atm.) |

UMD builds will not be supported in React 19. These are no longer widely used and the use case for using React from script tags without builds can be served by ESM using something like esm.sh.
…fixture looks to be in a state of significant bitrot. I'm not going to bother addressing these issues here but at the very least we can now render React 19 without UMD using this fixture
…te it to esm.sh i'm just removing it

In React 19 React will finally stop publishing UMD builds. This is motivated primarily by the lack of use of UMD format and the added complexity of maintaining build infra for these releases. Additionally with ESM becoming more prevalent in browsers and services like esm.sh which can host React as an ESM module there are other options for doing script tag based react loading. This PR removes all the UMD build configs and forks. There are some fixtures that still have references to UMD builds however many of them already do not work (for instance they are using legacy features like ReactDOM.render) and rather than block the removal on these fixtures being brought up to date we'll just move forward and fix or removes fixtures as necessary in the future. DiffTrain build for [da6ba53](da6ba53)

@sebmarkbage , do you have any guidance on how we can quickly test changes made to the local React source code using the React project provided under the fixtures, since we no longer have the option to use UMD builds for this purpose? |
