How do I make a POST request using fetch in JavaScript?

How do I make a POST request using fetch in JavaScript?

You can use the fetch API to make a POST request like this: fetch(url, { method: 'POST', body: JSON.stringify(data), headers: { 'Content-Type': 'application/json' } }). Replace url with your endpoint and data with the data you want to send.

What if I need to send additional headers?

You can add additional headers in the headers object. For example: headers: { 'Content-Type': 'application/json', 'Authorization': 'Bearer token' }.

How do I handle the response from the POST request?

You can handle the response by chaining a .then() method after the fetch call. For example: fetch(...).then(response => response.json()).then(data => console.log(data));.

Can I use async/await with fetch?

Yes, you can use async/await! Just wrap your fetch call in an async function like this: const response = await fetch(url, options);.
