JavaScript How to prevent render method from throwing error on a state that is initially set to undefined

I am trying to render my state which updates by pulling data from an api so the initial value of the state is undefined. I am receiving the error TypeError: undefined is not an object (evaluating 'this.state.Pods[0].Name'). From what I understand about react, every time the state is updated the components that use that state re-renders, so the text that initially was undefined will then render the updated state value. My question is could you bypass the initial error from being thrown so it can render the value of state when its updated. Here's how im calling the state:

<Text>{this.state.Pods[0].Name}</Text>

Ive tried using getDerivedStateFromError but I it isn't working for me.

static getDerivedStateFromError(error) {
        return { hasError: true };
      }

 render() {
        if (this.state.hasError) {
            return <Text>Something went Wrong</Text>
        }
Answer:1

Please use this

  render() {
    if (!this.state.Pods || !this.state.Pods[0] )  {
        return <Text>Loading</Text>
    }

That is not the correct way of using error boundary component. if you are expected

class ErrorBoundary extends React.Component {
  constructor(props) {
    super(props);
    this.state = { hasError: false };
  }

  static getDerivedStateFromError(error) {
    // Update state so the next render will show the fallback UI.
    return { hasError: true };
  }

  render() {
    if (this.state.hasError) {
      // You can render any custom fallback UI
      return <h1>Something went wrong.</h1>;
    }

    return this.props.children; 
  }
}

In your component.

render() {
  <ErrorBoundary>
    <Text>{this.state.Pods[0].Name}</Text>
  </ErrorBoundary>
}

though you don't need error boundry in your case. you should read your state safely as suggested in other answers.

Answer:3

You have to update your code as below.

<Text>{Array.isArray(this.state.Pods) && this.state.Pods.length > 0 && this.state.Pods[0].Name}</Text>

Hope this will work for you!
