What is the best way to display nested JSON in JSX within a React Native application?

I need help with rendering nested JSON inside my JSX. Below is the JSON response:

[{
    "data": {
        "total_students": 13,
        "seats": "",
        "categories": [{
            "id": 28,
            "name": "Economy",
            "slug": "economy",
        }],
        "instructor": {
            "id": "24",
            "name": "Ad",
            "sub": ""
        },
        "menu_order": 0
    },
    "headers": [],
    "status": 200
}

This is how the response looks like. In order to render it in React, you can use the following code:

return this.state.user.map(user =>

        <CardSection>
        <View style={styles.thumbnailContainerStyle}>
        <Text key= {user.data.name} style={styles.userStyle}>{this.state.user.data}</Text>
        </View>
        </CardSection>

I have attempted the above approach but encountered an error during rendering: cannot define name of undefined. Can someone please assist me in figuring out what I am doing wrong?

Answer №1

The key name is missing from the data object and is currently set to undefined. To access nested JSON, follow these examples:

  • Access the name in instructor: user.data.instructor.name
  • Access the names in categories (as an array):
    user.data.categories.map(category => category.name)

Answer №2

user.data.name is not found in the JSON data you received. It's possible that the name is under user.data.instructor.name.
