If you are on a Mac, substitute command for control. Don't type the + (it means press both keys at once).

Shortcuts when in either command mode (outside the cells) or edit mode (inside a cell):

Shift + Enter run selected cell or cells - if no cells below, insert a code cell below
Ctrl + B toggle hide/show left sidebar
Ctrl + S save and checkpoint
Ctrl + Shift + S save as

Create your library

Initialize project npm init -y

Create esm module ./src/esm/my-lib.js

function addNumber(value, value2) {
  return value + value2;
}

export { addNumber };

HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

	# - If you are already on the right Node version, IT DOES NOTHING, AND PRINTS NOTHING.
	#
	# - Works correctly if your .nvmrc file contains something relaxed/generic,
	# like "4" or "v12.0" or "stable".
