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"))
