Bug: Where is react.mjs download for browser? about react

[gaearon]

We don't currently provide a purely ESM build out of the box, so you will have to build it yourself the same way that these CDNs do. We don't think realistically this is a great way to consume React today anyway, since it's not very usable without import maps, and import maps have barely landed across browsers. We'll revisit this in the future.

I am the beginner , can anyone tell me how can i run my changes on react source code ?

[markerikson]

Per #11503 , React does not currently ship any ES module builds.

Some CDNs do automatic conversion of React for use as an ESM script tag - you can try using that:

@markerikson that's a great suggestion

Hi @MeastroZI, I found something in the readme file which can help you with further investigation for your usecase

Thanks, but I can't use a CDN for any libraries because I often work offline.

您可以使用我这个来转换 jsx，不过是手动的

@Bibooo25730 Thanks.

@j4acks0n Thanks. VSCode. I downloaded mjs version from a CDN and it works fine for me for now.

@gaearon
Import maps are present in all major browsers already and aren't going anywhere so how "barely landed" is a problem in any way?
That's a very weird argument.
Anyway, it's possible to export React as a single react.mjs without using import maps.
IMO, it's better to have /dist/ folder and a installation notice (e.g. "mjs is not recommended but available") than no /dist/ folder.

根据 #11503 ，React 目前没有发布任何 ES 模块构建。

一些 CDN 会自动转换 React 以用作 ESM 脚本标签 - 您可以尝试使用它：

Thank! It works very well !
