RESTful CRUD for Angular and Express $resource - node.js

Question

I have my JSON querying and creating correctly. I'm a bit stuck on how to remove items from the server. They are being removed in angular but I can't seem to get the connection right for removing them on the server.
My server.js:
var hcController = require('./server/controllers/services-controller.js')
//REST API
app.get('/api/hc', hcController.list);
app.post('/api/hc', hcController.create);
app.delete('/api/hc:_id', hcController.delete);
My server-side model
var mongoose = require('mongoose');
module.exports = mongoose.model('HealingCenterData',{
title: String,
shortname: String,
summary: String,
description: String
});
My server-side controller
var Hc = require('../models/healingcenter-model.js')
module.exports.create = function (req, res) {
var hc = new Hc(req.body);
hc.save(function (err, result){
res.json(result);
});
}
module.exports.list = function (req,res) {
Hc.find({}, function (err, results){
res.json(results);
});
}
module.exports.delete = function (req, res) {
???????
});
}
My angular service:
app.factory("HC", ["$resource", function($resource) {
return {
API: $resource('/api/hc/:id')
}
}]);
My angular controller:
app.controller('servicesController', ['$scope', 'HC','$resource', function ($scope, HC, $resource) {
HC.API.query(function(results) {
$scope.services = results;
});
$scope.createService = function() {
var service = new HC.API();
service.title = $scope.serviceTitle;
service.shortname = $scope.serviceShortname;
service.summary = $scope.serviceSummary;
service.description = $scope.serviceDescription;
service.$save(function(result){
$scope.services.push(result);
$scope.serviceTitle = '';
$scope.serviceShortname = '';
$scope.serviceSummary = '';
$scope.serviceDescription = '';
});
}
$scope.removeItem = function(index){
$scope.services.splice(index, 1);
}
}]);
My JSON structure
{ "_id" : ObjectId("53bea9366a03a66c2dad68bb"), "title" : "Auto Clinic", "shortname" : "auto_clinic", "summary" : "Volunteers evaluate car problems and make minor repairs. Labor is free, and the car owner pays for any needed parts. Oil changes are performed at a reduced cost. All services are performed on Saturdays.", "description" : "No additional information yet.", "__v" : 0 }

On the server side try (I'm assuming you are using moongose) :
exports.delete = function(req,res){
if(req.params.id !==null || req.params.id!==undefined){
Hc.remove({_id:req.params.id},function(err){
res.send(200);
});
}
};
on the client side:
angular controller:
var endPoint = $resource('/api/hc/:id', {id:'#tId'});
$scope.removeItem = function(id){
var ep = new endPoint({tId:id});
ep.$delete(function(res){
//TODO: update local array in scope
});
};
EDIT:
you can just use the resource directly in the controller or just the service as you have done in your case, that's totally fine.
