So far, you have learned how to get data from an API. But real-world applications also need to send data to servers.
This is done using POST requests. POST is used when you submit forms, create new users, save messages, or store any information in a database.
Learning how to send data with POST requests is a key step toward building full-stack and professional web applications.
When to Use POST Requests
- Submitting contact or login forms
- Registering new users
- Saving data to a database
- Sending feedback or messages
- Creating new records in a system
POST requests allow your app to send data securely to the server.
In real applications, this message represents sending form data or user information to a server.
Now let’s see how this works using fetch().
Here, data is sent to the server using the POST method.
The body contains the information converted into JSON format.
These examples show how JavaScript sends data to a server using POST requests.
By mastering POST requests, students gain the ability to build interactive applications that not only display data but also save and manage real user information.
