React: What's the best way to implement component update?

Question

React

There is a component in which a third-party lib is used for rendering, that is, in render simply

render() {
    return <div ref={(el) => (this.сontainer = el)} />
  }

and all the logic is in componentDidMount (initialization) and componentDidUpdate (props change processing)
The problem is that initialization takes some time, during which updated props have time to arrive. But I can't process them until the initialization is finished.
What can be done in this situation?
