Phaser hello world Updated +Created
Phaser.js Updated +Created
Likely the best JavaScript 2D game engine as of 2023.Uses Matter.js as a physics engine if enabled. There's also an alternative (in-house?) "arcade" engine: photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.ArcadePhysics.html but it appears to be simpler/less robust (but also possibly faster).
TODO any 2D first person examples a bit like Ciro's 2D reinforcement learning games?
The examples are present under:
git clone https://github.com/photonstorm/phaser3-examples
but note that that repo is huge, about 4.5 GiB on local disk, as is has tons of assets.
The demos also include a Monaco-editor based sandbox mode where you can edit code directly on the web and see the game update which is a really sweet addition.

Once HTTP inbound traffic is enabled on security rules for port 80, you can:
while true; do printf "HTTP/1.1 200 OK\r\n\r\n`date`: hello from AWS" | sudo nc -Nl 80; done
and then you are able to curl from your local computer and get the response.

better-sqlite3 Node.js package Updated +Created
As claimed on their README, their operation truly appears to be 10x faster than the node-sqlite package!! It is insane!! How can that other package still exist at all?
The only big problem was the lack of ORM, but people are looking into that by adding it to Sequelize:
