Error Handling
When working with the Fetch API, a robust error-handling strategy is crucial, particularly for POST requests involving sensitive data. Utilize a try/catch block to encapsulate your code, with the catch() method to manage errors
Example: Error handling in Fetch API
Below is an example how how to handle errors while using fetch API.
try {
const response = await fetch('https://api.example.com/data', {
method: 'POST',
body: JSON.stringify(data),
headers: {
'Content-Type': 'application/json'
}
});
if (!response.ok) {
throw new Error('Network response was not ok');
}
const result = await response.json();
console.log('Response:', result);
} catch (error) {
console.error('Error:', error);
}
Explanation:
The code uses a try/catch block to handle errors during a POST request using the Fetch API. It sends data to ‘https://api.example.com/data’, with JSON formatting. If the response is not successful, it throws an error. The catch block logs any errors encountered during the process.

How to use JavaScript Fetch API to Get Data?
An API (Application Programming Interface) is a set of rules, protocols, and tools that allows different software applications to communicate with each other.
One of the popular ways to perform API requests in JavaScript is by using Fetch API. Fetch API can make GET and POST requests, JavaScript’s Fetch API is a powerful tool for developers seeking to retrieve this data efficiently. This guide focuses on using Fetch API to master the art of “GET” requests, the essential method for gathering information from APIs.
