Emscripten to JS library? about flecs HOT 2 CLOSED

Thanks for the quick reply. It seems like it'll be too much work to integrate it; I'll look for alternatives, or maybe a mini re-implementation.

from flecs.

The emscripten examples (like https://www.flecs.dev/tower_defense/etc/) are indeed projects that run standalone in C/C++ with little to no JS code involved.

If you want to build a JS game with Flecs you'll have to manually wrap the Flecs functions you want to use, and export them with EMSCRIPTEN_KEEPALIVE (which admittedly would be a lot of work).

You can alternatively take a look at the Flecs Javascript library: https://www.flecs.dev/explorer/flecs.js which wraps around the Flecs REST API.

This JS API is not really optimized for client-side game development though, as it is more intended for connecting to a (remote) running (C/C++) flecs application.

TL;DR: it's possible but will likely require quite a bit of work.
