points
In this article, we would like to show you how to make AJAX PATCH requests with Express.js.
1. Express.js PATCH methods example
In this section, we use Express.js to handle PATCH requests.
index.js file:
const express = require('express'); // installation: npm install express
const port = 3000;
const app = express();
app.patch('/examples', (request, response) => {
const data = request.body;
// make partial changes to an existing resource
response.send('put your changed data here');
});
app.listen(port, () => {
console.log(`server is listening at http://localhost:${port}`);
});
To run the server use:
node index.js
Output:
server is listening at http://localhost:3000
2. Pure JavaScript (Vanilla JS) AJAX PATCH request
The following is an example execution of a fetch method that sends PATCH requests.
<!DOCTYPE html>
<html>
<body>
<script>
var requestData = 'Some text sent to API ...';
fetch('/examples', {
method: 'PATCH',
headers: {
'Content-Type': 'text/plain',
},
body: requestData
})
.then((response) => response.text())
.then((responseData) => {
console.log('Success: ', responseData);
})
.catch((error) => {
console.error('Error: ', error);
});
</script>
</body>
</html>
