+# How to use MeowForms with Node.js
+
+First, make sure you have signed up at [MeowForms](https://meowform.xyz) and created a form.
+
+## Requirements
+
+- Node.js
+- Express.js
+- Axios
+
+To handle your form data with Node.js, you must send them from the frontend by using a POST request. A basic HTML form could look like this:
+
+```html
+<!-- "/handleform" is the name of the route that will process the form data -->
+<form action="/handleform" method="POST">
+  <label for="email">E-Mail</label>
+  <input type="email" name="email" id="email" />
+
+  <label for="name">E-Mail</label>
+  <input type="text" name="name" id="name" />
+
+  <button type="submit">Send</button>
+</form>
+```
+
+When you use Express.js, you need to add the following code to add a route that serves the HTML file with the form:
+
+```javascript
+/* "/form" is the name of the route that serves the form  */
+app.get('/form', (req, res) => {
+  res.sendFile(__dirname + '/form.html') /* form.html is the name of your HTML file */
+})
+```
+
+Next, you need to enable Express.js to parse JSON bodies and URL-encoded bodies:
+
+```javascript
+app.use(express.json())
+app.use(express.urlencoded())
+```
+
+Finally, add the code for the route to process the form data and send it to MeowForm:
+
+```javascript
+app.post('/handleform', async (req, res) => {
+  /* Destructure form values from the request body */
+  const { name, email } = req.body
+
+  /* Send the values to MeowForm with another POST request */
+  const request = await axios({
+    method: 'post',
+    /* Replace [email protected] with your email and SomeForm with the name of your form */
+    url: 'https://server.meowform.xyz/form/[email protected]&SomeForm',
+    data: {
+      name,
+      email,
+    },
+  })
+
+  if (request.status === 200) {
+    res.status(200).json({ message: 'success' })
+  } else {
+    res.status(500).json({ message: 'an error occured' })
+  }
+})
+```
