`UPLOAD('POST /url/', formdata, callback, onprogress)` posts a `FormData` (the address starts with the HTTP method, like in `AJAX()`) and calls the callback with the parsed response. The optional fourth argument receives the percentage while the upload runs. Build the `FormData` from a file input (`new FormData()` and `append('file', input.files[0])`); the server side is the `@upload` route of the file upload recipe.
```js controllers/upload.js
exports.install = function() {
ROUTE('POST /upload/ @upload <5mb', upload);
};
function upload($) {
var file = $.files[0];
file.read(function(err, buffer) {
$.json({ filename: file.filename, text: buffer.toString('utf8'), title: $.body.title });
});
}
```
