?️ React Native DELETE API

? Quick Overview

The DELETE API in React Native is used to remove data from a backend server. It is commonly used to delete users, posts, products, or any resource identified by an ID.

? Key Concepts

• DELETE request removes a resource
• Usually requires an ID or unique identifier
• Uses HTTP method DELETE
• Handled using fetch() or Axios

? Syntax / Theory

A DELETE request sends a request to the server without a request body in most cases. The server processes the request and removes the specified resource.

// Basic DELETE request syntax using fetch
fetch("https://example.com/api/users/5", {
  method: "DELETE"
});

? Code Example(s)

// Delete user by ID using fetch API
const deleteUser = async (userId) => {
  try {
    const response = await fetch(`https://example.com/api/users/${userId}`, {
      method: "DELETE"
    });
    
    if (response.ok) {
      console.log("Deleted successfully");
    }
  } catch (error) {
    console.error(error);
  }
};

? Interactive Example

  <View>
    <Text>{name}</Text>
    <Button title="Delete" color="red" onPress={() => onDelete(id)} />
  </View>
);
