How to delete Amazon s3 file w/ nodejs / angular - angularjs

Question

var awsSdk = require('aws-sdk');
awsSdk.config = {
"accessKeyId": "key",
"secretAccessKey": "secret",
"region": "us-east-1"
}
var s3 = new awsSdk.S3({
accessKeyId: 'key',
secretAcessKey: 'secret'
});
exports.awsDelete = function(req, res){
s3.deleteObject({
Bucket: 'bucket',
Key: req.body.photo
}, function(err,data){
if (err) console.log('delete err', err);
console.log(data);
});
};
I can't figure out how to make this work (yet).
initially, I was getting a "no config" error, so I added the awsSdk.config json above. Now, it's just getting hung / pausing with no error. I am getting the expected key in req.body.photo.
My hunch is that i'm missing something in my config..
What am I missing / screwing up?
Update
I've added the code suggested below, but still no luck. I'll show how i'm passing my parameter:
updated code from answer below:
'use strict';
var aws = require('./aws');
var amazon = require('aws-sdk');
amazon.config = new amazon.Config();
amazon.config.accessKeyId = aws.key;
amazon.config.secretAccessKey = aws.secret;
amazon.config.region = aws.region;
var s3 = new amazon.S3();
exports.awsDelete = function(req, res){
var params = {
Bucket: aws.bucket,
Key: res.body.photo
};
s3.deleteObject(params, function(err, data) {
if (err) console.log(err)
else console.log("Successfully deleted myBucket/myKey");
});
};
route:
app.post('/awsDelete', uploads.awsDelete);
Front end Angular:
factory:
angular.module('clientApp').factory('Uploads', function($http) {
return {
delete: function(data){
console.log('delete fired');
return $http.post('/awsDelete', data);
}
};
});
angular controller:
angular.module('clientApp').controller('Distiller-editCtrl', function(Uploads){
$scope.item = {}
$scope.delete = function(){
Uploads.delete($scope.item).then(function(res){
console.log(res)
});
};
});
Seems it 'sort of works'. But something is making it take an extremely long time:
POST /awsDelete 200 120007ms
If I refresh the page, that causes it to successfully delete it as well.
Does anyone notice anything in my code that could be causing such a long response time.
Also, not getting the "successfully completed" console.log

I just tested this in node and it worked fine, obviously you need to put in your own accesskey, secretaccesskey, bucket and bucket key:
var AWS = require('aws-sdk');
AWS.config = new AWS.Config();
AWS.config.accessKeyId = "";
AWS.config.secretAccessKey = "";
AWS.config.region = "us-east-1";
var s3 = new AWS.S3();
var params = {
Bucket: 'test537658ghdfshgfd',
Key: '1.png'
};
s3.deleteObject(params, function(err, data) {
if (err) console.log(err)
else console.log("Successfully deleted myBucket/myKey");
});

Alternatively you can use Minio-Js client library, its Open Source and compatible with AWS S3.
Below is remove-object.js example, you can find complete list here
var Minio = require('minio')
var s3Client = new Minio({
endPoint: 's3.amazonaws.com',
accessKey: 'YOUR-ACCESSKEYID',
secretKey: 'YOUR-SECRETACCESSKEY'
})
// Remove an object name my-objectname.
s3Client.removeObject('my-bucketname', 'my-objectname', function(e) {
if (e) {
return console.log(e)
}
console.log("Success")
})
Please replace YOUR-ACCESSKEYID and YOUR-SECRETACCESSKEY with your own also replace the endPoint to the one you have your bucket is created.
us-east-1: 's3.amazonaws.com',
us-west-1 : 's3-us-west-1.amazonaws.com',
us-west-2 : 's3-us-west-2.amazonaws.com',
eu-west-1: 's3-eu-west-1.amazonaws.com',
sa-east-1: 's3-sa-east-1.amazonaws.com',
eu-central-1: 's3-eu-central-1.amazonaws.com',
ap-southeast-1: 's3-ap-southeast-1.amazonaws.com',
ap-southeast-2: 's3-ap-southeast-2.amazonaws.com',
ap-northeast-1: 's3-ap-northeast-1.amazonaws.com'
Installing Monio-js
$ npm install --save minio
Hope it helps.
