Sending SMS via Twilio POST error - angularjs

Question

This comes after half a day of banging my head against the screen, so any help would be greatly appreciated.
I'm trying to send an SMS message via Twillio on a click-event. I'm using Angular, calling the SendTestMessage function on click. Unfortunately, I keep running into this error:
POST http://localhost:3000/sendsms 500 (Internal Server Error)
Here is my controller:
.controller('WhotoMessageCtrl', function($scope, UserService, $http, $q){
console.log("whotomessage page");
$scope.saveContactInfo = saveContactInfo;
$scope.contact = {};
$scope.sendTestMessage = sendTestMessage;
function sendTestMessage(number){
console.log('this fired', number);
var defer = $q.defer();
$http({
url: '/sendsms',
method: 'POST',
data: JSON.stringify({number}),
contentType: 'application/json',
}).success(function (number){
console.log('text has been sent to', number);
defer.resolve(user);
});
return defer.promise;
};
Here is my server side code:
app.all('*', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', 'OPTIONS,GET,POST,PUT,DELETE');
res.header("Access-Control-Allow-Headers", "Content-Type, Authorization, X-Requested-With");
if ('OPTIONS' == req.method){
return res.send(200);
}
next();
});
app.use(function (req, res, next) {
var sendSMS = function(to){
var outgoing = {};
outgoing.to = to;
outgoing.from = '19725593683';
outgoing.body = 'Your table is ready';
client.messages.create(outgoing, function(error, message){
if (error){console.log(error.message)}
})
};
app.post('/sendsms', function(req, res){
sendResponse(res, req.body.phoneNo, 201)
sendSMS(req.body.phoneNo)
res.end();
});
Any suggestions?

Hey Twilio developer evangelist here.
It could have been that you forgot to copy bits of the code, but it seems client hasn't been defined, which means you aren't even making a request to Twilio.
The correct way to initialise client according to the documentation is:
// Your accountSid and authToken from twilio.com/user/account
var accountSid = '{{ account_sid }}';
var authToken = "{{ auth_token }}";
var client = require('twilio')(accountSid, authToken);
Only then you can on your code do:
var sendSMS = function(to){
var outgoing = {};
outgoing.to = to;
outgoing.from = '19725593683';
outgoing.body = 'Your table is ready';
client.messages.create(outgoing, function(error, message){
if (error){console.log(error.message)}
})
};
Hope this helps you!
