kutuluk / js13k-ecs Goto Github PK

When importing the library using an import statement on node, it crashes because of the following line:

The reason is that performance is not defined and ESM imports run files in strict mode.

I'm using js13k-ecs in a roguelike project for pretty much everything in the game. It's going along great but I ran into a little hurdle that I hadn't quite decided how to overcome. Basically, I created a set of Entity classes that collected all the necessary bits and threw them into the ECS for me during the constructor. Essentially freeing me up to simply put down let player = new Player(...); and end up with everything in place.
All fine and dandy until I realized that my player object was not a part of the Entity class itself and therefore would need constant workaround of stuff like player.entity to access the ECS belonging to the object, and by extension any related components.
To simplify, I thought I could extend the js13k-ecs Entity class so that the Player class would play well (hah) with the ECS directly. Sadly, the Entity class is not exported so that's not possible.

What I'm curious about is, am I breaking something or doing something wrong if I simply added the export keyword to the Entity class in my version (and, should we add it to the entire module this way)? I'm self-taught at JS and it's entirely possible that I've missed something obvious. I appreciate any feedback you have. Thanks.
