colyseus VS LandOfTheRair

If you don't want to dive deep into backend then https://colyseus.io/ might also be an option.

Since you already know Javascript you could try to use some existing server framework at first to avoid having to do everything from scratch. https://github.com/colyseus/colyseus

Try this Node.js based server framework https://github.com/colyseus/colyseus

https://colyseus.io/ (Authoritative server, that works with many engines JavaScript/Phaser/Unity/Haxe/Defold)

If you want web based you'll likely use Javascript for frontend/client. Check if this JS game server framework has what you need https://github.com/colyseus/colyseus

Also check Colyseus. Bit similar multiplayer server framework and built on top of Node.js/TypeScript. https://github.com/colyseus/colyseus

The above project uses a Node.js authoritative game state called Colyseus (https://github.com/colyseus/colyseus) which handles the state synchronisation between clients and server.

We use Colyseus for this. Pretty easy and open source too. https://colyseus.io/

I got pretty far with a 20$ server: https://github.com/LandOfTheRair/LandOfTheRair/

You'll probably want to use a canvas for anything visual, but you can certainly do a lot with angular. My game renders a map, player, and monsters with phaser (canvas/webgl) and everything else is done with angular. Visual example

While they're not very popular, I have been making one. My end goal will be desktop apps with electron, or you can play in the browser if needed.

It's not open world, but I've been working on what I'd like one day to be an MMO.

https://rair.land (disclaimer: I'm making it) is an open source MMO.

You're welcome. If you're looking for more implementation ideas, I have it here. Basically, on version it'll do everything, generate a changelog and a current changelog (I use this to publish only the most recent set of changes in a github release), commit the changelog, and then a script to untag and retag the current version to include the changelog.

Nothing fancy, just a lot of overrides (and some more here). Just a bunch of small changes that eventually became somewhat cohesive. The easiest things you can change to affect material:
