This recipe is for advanced usages of Lighthouse as a Node library.
Normally, Lighthouse runs Chrome and generates a set of artifacts to use as input to many core modules (such as audits or computed artifacts). You can use these modules directly, but you must provide the inputs yourself.
Oh boy :) cracks knuckles tl;dr no, also I overlooked so much, thanks for pointing this out.
The minified JS I linked to is every polyfill that @babel/present-env would provide. The recommended distribution of these polyfills is not the module I linked (@babel/polyfill), but instead via @babel/preset-env. Regardless, they both use the polyfills as defined by core-js. You can see that the polyfills module has a standard bundling and minifying script: https://github.com/babel/babel/blob/fced5cea430cc00e916876b663a8d2a84a5dad1f/packages/babel-polyfill/scripts/build-dist.sh, which is what I linked to before. The question is: does the pattern I'm looking for hold for these core-js polyfills regardless of the minifier used? Additionally: where does this pattern come from? I'll focus on that first.
To further complicate, there's core-js@2 and core-js@3, and both seem to be used (or at leas

Question came up during the homework review for express-blogpulse: how to redirect a route relative to the Router being used? Example, on POST /post, how can we best redirect to GET /post/:id for the newly created post?
Answer: use req.baseUrl. click for docs: http://expressjs.com/en/4x/api.html#req.baseUrl.
Something like req.redirect(req.baseUrl + "/" + post.id)
req.baseUrl would be equal to /post in this case, because of the line app.use("/post", require("controllers/post.js"))
