Update links to use https:// where it is supported. There's probably a lot more that could be fixed, but these are the core ones I found (especially the download links in order to prevent MITM attacks). Note that there are some fb.me links that will redirect to http:// even while accessed over https://, but this seemed like the best way to fix those for now. NOTE: Only non-third-party files were modified. There are references to http:// URLs in vendored/third-party files, but seems appropriate to fix upstream for those rather than editing the files. Also, copy one image locally to the blog, as it was hotlinking to a site that did not support https://. Last, use youtube-nocookie.com instead of youtube.com for video embeds, as the former doesn't try to set a cookie on load (privacy enhancement).

Every project uses a different system for building and deploying JavaScript. We've tried to make React as environment-agnostic as possible.
React
CDN-hosted React
We provide CDN-hosted versions of React on our download page. These prebuilt files use the UMD module format. Dropping them in with a simple <script> tag will inject a React global into your environment. It should also work out-of-the-box in CommonJS and AMD environments.
Using master
We have instructions for building from master in our GitHub repository. We build a tree of CommonJS modules under build/modules which you can drop into any environment or packaging tool that supports CommonJS.
JSX
In-browser JSX Transform
If you like using JSX, we provide an in-browser JSX transformer for development on our download page. Simply include a <script type="text/jsx"> tag to engage the JSX transformer.
Note:
The in-browser JSX transformer is fairly large and results in extraneous computation client-side that can be avoided. Do not use it in production — see the next section.
Productionizing: Precompiled JSX
If you have npm, you can simply run npm install -g react-tools to install our command-line jsx tool. This tool will translate files that use JSX syntax to plain JavaScript files that can run directly in the browser. It will also watch directories for you and automatically transform files when they are changed; for example: jsx --watch src/ build/.
By default JSX files with a .js extension are transformed. Use jsx --extension jsx src/ build/ to transform files with a .jsx extension.
Run jsx --help for more information on how to use this tool.
Helpful Open-Source Projects
The open-source community has built tools that integrate JSX with several editors and build systems. See JSX integrations for the full list.
