Store.getstate is not a function

by

Explanation:

The error message “store.getstate is not a function” typically occurs when you’re trying to call the “getstate” function on an object that is not defined as a store or doesn’t have the “getstate” function.

Example 1:

    
      const store = {
        state: {
          name: "John",
          age: 25
        }
      };
      
      console.log(store.getstate()); // Error: store.getstate is not a function

In this example, we have a custom object “store” that has a “state” property. However, there is no “getstate” function defined for the “store” object. Hence, calling “store.getstate()” results in the error.

Example 2:

    
      const reduxStore = createStore(reducerFunction);
      
      console.log(reduxStore.getstate()); // Error: reduxStore.getstate is not a function

In this example, we are using Redux to create a store using the “createStore” function. However, the correct function to retrieve the state is “getState” (with capital ‘S’), not “getstate”. Hence, calling “reduxStore.getstate()” results in the error.

Solution:

To fix the error, you should ensure that you are calling the correct method and have the object defined as a store with the necessary functions. Here are a couple of possible solutions:

Solution 1 – Custom store object:

    
      const store = {
        state: {
          name: "John",
          age: 25
        },
        getstate: function() {
          return this.state;
        }
      };
      
      console.log(store.getstate()); // {name: "John", age: 25}

In this solution, we define a “getstate” function within the “store” object to retrieve the state. Now, calling “store.getstate()” will return the state object correctly.

Solution 2 – Redux store:

    
      const reduxStore = createStore(reducerFunction);
      
      console.log(reduxStore.getState()); // Current state stored in Redux store

In this solution, we use the correct function “getState” provided by Redux to retrieve the current state from the store. Now, calling “reduxStore.getState()” will return the current state stored in the Redux store.
