dispatch is not a function TypeError

I'm new to react-redux and I'm using the react-thunk middleware. I'm getting the error "Uncaught TypeError: dispatch is not a function" whenever I try to run my action creator (by pressing my button). Anyone know what's going on?

src/actions/index.js

function editUserName (newUserName) {
    return {
        type: 'CHANGE_USER_NAME',
        newUserName: newUserName
    }
}

export function editUserNameDelegate () {
    return function (dispatch, getState) {
        return dispatch(editUserName("thunkUser"))
    }
}

src/containers/admin.js

import { editUserNameDelegate } from '../actions/index'
...
<input type="button" onClick={ editUserNameDelegate() } value="edit UserName" />

If This Error Is As A Result Of Using context you might consider importing it as: const {state, dispatch} = useContext(location of the context)

You should provide what is src/containers/admin.js function or class?

If it is function component you should use onClick={() => editUserNameDelegate()}

You're executing the editUserNameDelegate function inside of render, instead of passing it as the onClick handler. You want onClick={editUserNameDelegate} instead.

Also, if you're writing it that way, you need to make sure that the function is bound up to dispatch when you call it. You can do that like:

export default connect(null, {editUserNameDelegate})(MyComponent)

And then pass onClick={this.props.editUserNameDelegate} in your render function.

The store is what provides the dispatch function. So you either need to connect your component to the store using something like connect from react-redux (https://github.com/reactjs/react-redux), or you need to call store.dispatch(editUserNameDelegate()).

You also need to make sure you have added redux-thunk as middleware in your store. See more about redux-thunk here: https://github.com/gaearon/redux-thunk
