Custom Rules

no-dispatch-getstate

Prevents passing a redux store's getState into its dispatch as an unnecessary second argument.

We started doing this accidentally at some point because of a misunderstanding about how redux-thunk worked, so this stops anyone from making that same mistake again.

Examples of incorrect code for this rule:

export function someAction() {
    return (dispatch, getState) => {
        dispatch(doSomething(), getState);
    };
}

Examples of correct code for this rule:

export function someAction() {
    return (dispatch) => {
        dispatch(doSomething());
    };
}
