Currently playing around with Angular 2 RC.
Is there any tutorial/article that would help me understand uploading a file to the back-end via a REST call?
I've been through this, but it feels like there should be a more convenient way of doing it.

If you wait for RC2, you will have the ability to use other payloads than text ones.
For example Blob ones:
var headers = new Headers({'Content-Type': 'text/css'});
var body = new Blob(['body { color: red; }']);
return this.http.post('/url', body, { headers });
Arraybuffer ones:
var headers = new Headers({'Content-Type': 'text/css'});
var body = new ArrayBuffer(512);
var longInt8View = new Uint8Array(body);
for (var i = 0; i < longInt8View.length; i++) {
longInt8View[i] = i % 255;
}
return this.http.post('/url', body, { headers });
FormData ones:
var body = new FormData();
body.append('test1', 'val1');
body.append('test2', 123456);
var blob = new Blob(['body { color: red; }'], {type: 'text/css'});
body.append("userfile", blob);
return this.http.post('/url', body, { headers });
It would much easier to handle binary content for HTTP requests. Right now, it's difficult (and hacky) since Angular2 only accepts text payloads as input.

Thanks for the info @Thierry, I've been looking for the status of those request methods, didn't manage to find it (;

@Sasxa you're welcome! RC2 was just released so you should find this in it ;-)
