html file:

<head> 
	  <script type="text/javascript src="sendreq.js"></script>
	  </head>
	  <div id="button">
	    <form>
         <input type="button" id="req" value="chiedi amicizia" onclick="mandarichiesta()" />
        </form>
	  </div>

sendreq.js:

<script>
 export function sendRequest(method,url,params,keys){
		  var data=new FormData()
		  for (let i = 0; i < params.length; i++) {
			data.append(keys[i], params[i]);
          } 
		  var http = new XMLHttpRequest();
          http.open(method, url, true);

          http.onreadystatechange = function() {//Call a function when the state changes.
            if(http.readyState == 4 && http.status == 200) {
				return http.responseText;
            }
			
          }
          http.send(data);
	  }
		export function richiediamicizia(){
		  var scelta="richiestamicizia";
          var dest="'.$_GET["username"].'"		  
		  var k=["scelta","dest"];
		  var p=[scelta,dest];
		  return sendRequest("POST","messages.php",p,k);
		}
		export function mandarichiesta(){
			alert("tasto premuto");
			document.getElementById("button").innerHTML=richiediamicizia();

Looks like you have an extra closing bracket } just before the line http.send(data);

Just delete that } and check.

it's not extra, it closes sendrequest

export is used for JavaScript modules[^], not regular scripts.

If you want to load your script as a module, you need to use type="module", not type="text/javascript". You'll need to use Javascript to attach your event handler - onclick won't be able to find the export.

If you want to use a regular script file, remove the export keywords from your file.

Read my answer again; you cannot use onclick to reference an exported function from a module.

Either use Javascript to attach your event handler, or switch to using a normal script instead.
