How do I make a POST request using TypeScript and Fetch API?

You can use the Fetch API to make a POST request in TypeScript like this:

fetch('https://example.com/api', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ key: 'value' }),
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

What should I include in the headers for a JSON request?

For a JSON request, you should include the 'Content-Type' header set to 'application/json'. This tells the server that you're sending JSON data.

How can I handle errors in the fetch request?

You can handle errors by using the .catch() method at the end of your fetch call. Additionally, check the response status to handle different HTTP errors.

Can I send form data instead of JSON?

Yes, you can send form data by using the FormData object. Just replace the body in the fetch options with new FormData(formElement);.
