Store

createStore is a tiny pub/sub. It is not Redux.

import { createStore } from "svenjs";

const store = createStore({
  state: { posts: [] },
  init() {
    fetch("/api/posts")
      .then((r) => r.json())
      .then((posts) => this.set({ posts }));
  },
});

const off = store.subscribe((state) => {
  // attach to a component with setState if you want a re-render
});
store.get();
store.set((s) => ({ ...s, posts: [] }));
off();

listenTo is an alias for subscribe. emit(data) is an alias for set(data).
