Службы \ DataServices.js:
var Database = require('arangojs');
var db = new Database({url:'http://127.0.0.1:8529'});
module.exports = {
getAllUsers : function()
{
return db.database('nodeArangoWebAppDB')
.then(function (mydb) {return mydb.query('FOR x IN User RETURN x');})
.then(function (cursor) { return cursor.all();});
},
getUserByKey : function(userKey)
{
var bindVars = {'userKey': userKey};
return db.database('nodeArangoWebAppDB')
.then(function (mydb) {return mydb.query('FOR x IN User FILTER x._key == @userKey RETURN x',bindVars);})
.then(function (cursor) { return cursor.all();});
},
addUser : function(user)
{
return db.database('nodeArangoWebAppDB')
.then(function (mydb) {return mydb.collection('User');})
.then(function (collection) { return collection.save(user);});
},
updateUser : function(user)
{
var bindVars = {'key': user.key, 'username': user.username,"email":user.email };
return db.database('nodeArangoWebAppDB')
.then(function (mydb) {return mydb.query('FOR x IN User FILTER x._key == @key UPDATE x WITH { username:@username, email:@email } IN User',bindVars );})
.then(function (cursor) { return cursor.all();});
},
removeUser : function(userKey)
{
var bindVars = {'userKey': userKey};
return db.database('nodeArangoWebAppDB')
.then(function (mydb) {return mydb.query('FOR x IN User FILTER x._key == @userKey REMOVE x IN User LET removed = OLD RETURN removed', bindVars);})
.then(function (cursor) {return cursor.all();});
}
}
Что не так с этим:
return db.database('nodeArangoWebAppDB')
Каким было бы правильное кодирование (без Foxx)?
Какие изменения должны быть сделаны при реализации Foxx?
EDIT# 1:
Что не так с этим:
var db = new arangojs.Database('http://127.0.0.1:8529')
db.useDatabase("nodeArangoWebAppDB");
db.useBasicAuth("root", "root");
module.exports = {
getAllUsers : function(){
return db._query('FOR x IN User RETURN x')
.then(value) => { return value.all();};
},

Должны ли мы использовать Webpack?
