Method to obtain a reference to the current Pinia store: dynamic combination operation

Question

This is “roughly” what I want:

// This is a general composable function:
function export useGeneric() {
  function genericAct(){
    const store = getCurrentStore(); // This is what I need
    store.a.value = 42;
    store.act2(); // This action should be implemented using a common function in the store
  }
  return {genericAct}
}

// Here is an example store using it
export const useMyStore = defineStore('myStore', () => {
  const a = ref(1);
  const b = ref(1);
  const {genericAct} = useGeneric();
  function act2(){
    b.value = 43;
  }
  return {a, b, genericAct, act2};
}

How do I get the storage to which this action is bound? (Or how to pass it as an argument to useGeneric?)

(Of course, this is just the simplest example. In practical applications, I will use this to do more useful things...)

Answer 1

I don't know if this is the best approach, you may also consider @Estus Flask's comment:

But I ended up choosing to pass useMyStore as a parameter.

Please note that it should be called in every generic operation, because when useGeneric() is executed, the store has not yet been created.

The following is a code example:

// 这是一个通用的可组合函数：
function export useGeneric(getStore:any) { // 这里的类型定义非常困难，也许使用接口来避免使用 any 是最好的解决方案
  function genericAct(){
    const store = getStore(); // 这就是我需要的
    store.a.value = 42;
    store.act2(); // 这个操作应该在 store 中使用泛型来实现
  }
  return {genericAct}
}

// 这是一个使用它的示例 store
export const useMyStore = defineStore('myStore', () => {
  const a = ref(1);
  const b = ref(1);
  const {genericAct} = useGeneric(useMyStore);
  function act2(){
    b.value = 43;
  }
  return {a, b, genericAct, act2};
}
