How to load data differently in a component?

Question

React

I am creating a json tree. there is such a route

<Route path="entity/edit/:entity_id" component={EntityForm} />

Then in EntityForm

componentWillMount() {
    if(!isEmpty(this.props.entity_id)) {
      this.props.actions.loadEntityRequest(this.props.entity_id) //  устанавливает в reducer начальные данные структуры(entity)
    }
  }

Then I get the data via mapStateToProps

const mapStateToProps = (state, ownProps) => {
  return {
    entity: state.entity
  }
};

What a big problem for me. I get the structure every time I change it through mapStateToProps and it turns out that when the state changes, the tree is completely rebuilt. Is it possible to somehow get the initial data in a different way, so as not to be tied to the state?
