const counterReducer = (counter, action) => {
  switch (action.type) {
    case "DECREMENT":
      counter--;

    case "INCREMENT":
      counter++;
      return counter;
    default:
      return counter;
  }
};
const fetchDataReducer = (data, action) => {
  switch (action.type) {
    case "FETCH_DATA":
      data = action.data;
  }
  return data;
};
const reducers = {
  counter: counterReducer,
  data: fetchDataReducer
};

const store = new UpStore({ counter: 0 }, reducers);

export const actions = store.actions({
  decrement: async () => {
    return {
      type: "DECREMENT"
    };
  },
  increment: () => {
    return {
      type: "INCREMENT"
    };
  },
  fetchData: async url => {
    const data = await get(url).then(response => response.data);
    return {
      type: "FETCH_DATA",
      data
    };
  }
});

export default store;
```

import { Connect } from "upstore";

export default () => (
  <Fragment>
    <Connect
      store={store}
      filterState={state => {
        return { counter: state.counter };
      }}
    >
      {({ state }) => (
        <div>
          <h2>Counter Example</h2>
          <p>{state.counter}</p>
          <button onClick={actions.decrement}>decrement</button>
          <button onClick={actions.increment}>increment</button>
