<script> async, defer, async defer, module, nomodule, src, inline - the cheat sheet

With the addition of ES modules, there's now no fewer than 24 ways to load your JS code: (inline|not inline) x (defer|no defer) x (async|no async) x (type=text/javascript | type=module | nomodule) -- and each of them is subtly different.

This document is a comparison of various ways the <script> tags in HTML are processed depending on the attributes set.

If you ever wondered when to use inline <script async type="module"> and when <script nomodule defer src="...">, you're in the good place!

Note that this article is about <script>s inserted in the HTML; the behavior of <script>s inserted at runtime is slightly different - see Deep dive into the murky waters of script loading by Jake Archibald (2013)

The problem (AKA don't waste money)

One of my clients is a big company that has a very variable but predictable database usage pattern. In the weekdays morning they come up with a huge amount of INSERTs and UPDATEs while for the rest of the day, form noon on, the usage is fairly limited to a decent amount of SELECTs with very low writing activity. The smallest class type that can handle the morning's volume is db.r3.large but having such an instance running all day long and in the weekends is just a big waste of resources money (or a big favour we do to Amazon, from their point of view).

The solution

So I was wondering if there's some autoscaling mechanism for Aurora writers (there is, but only for replicas),

Generate ssl certificates with Subject Alt Names on OSX

Open ssl.conf in a text editor.

Edit the domain(s) listed under the [alt_names] section so that they match the local domain name you want to use for your project, e.g.

DNS.1   = my-project.dev

Additional FQDNs can be added if required:

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
