[02:06 PM] acemarke: @Steven : a couple other thoughts on the whole NODE_ENV thing. First, per my comments, it really is a Node concept. It's a system environment variable that Node exposes to your application, and apparently the Express web server library popularized using its value to determine whether to do optimizations or not
[02:08 PM] acemarke: Second, because of its use within the Node ecosystem, web-focused libraries also started using it to determine whether to they were being run in a "development" environment vs a "production" environment, with corresponding optimizations. For example, React uses that as the equivalent of a C #ifdef to act as conditional checking for debug logging and perf tracking. If process.env.NODE_ENV is set to "production", all those if clauses will evaluate to false.
Third, in conjunction with a tool like UglifyJS that does minification and removal of dead code blocks, a clause that is surrounded with if(process.env.NODE_ENV !== "development")

Hi,

I really like the embedded code snippets feature introduced last month,[1] but I just realized it doesn't work across repositories. Take this comment[2] as an example: currently, a snippet permalink into Linuxbrew/homebrew-core[3] is turned into an embedded snippet, but a snippet permalink into Linuxbrew/brew[4] is not. It would be really nice if cross-repo links are also converted. It would be beneficial to the Homebrew project for instance, where the package manager itself is developed in Homebrew/brew, the package definitions are developed in separate repos (what we call taps) like Homebrew/homebrew-core, and there are quite a bit of cross references between brew and taps. Thank you.

Best, Zhiming
