Baasbox and Javascript - mbaas

Question

I'm trying BaaSbox, a free Backend as a Service. But it has no out-of-the-box Javascript support I can use right away (yet, only iOS and Android)
I'm having trouble sending the right curl command from javascript, anyone happen to know a good resource or a simple working $.ajax template? I've tried a few examples from stackoverflow, but none of them specifically aimed at BaaSbox.
I've tried following the Java instructions on their site here. Just making a simple login work, but I keep getting the wrong responses from the server.
Or on the other hand, anyone know a good, free alternative to BaaSbox? I just want to be able to install it on my own server, no paid plans or whatever.

Answer 1

in the download page there is a preliminary version of the JS SDK (added few days ago).
The documentation is on the way, however in the zip file you can find a simple example.
For example to perform a signup:
//set the BaasBox parameters: these operations initialize the SDK
BaasBox.setEndPoint("http://localhost:9000"); //this is the address of your BaasBox instance
BaasBox.appcode = "1234567890"; //this is your instance AppCode
//register a new user
BaasBox.createUser("user", "pass", function (res, error) {
if (res) console.log("res is ", res);
else console.log("err is ", error);
});
Now you can login into BaasBox
//perform a login
$("#login").click(function() {
BaasBox.login("user", "pass", function (res, error) {
if (res) {
console.log("res is ", res);
//login ok, do something here.....
} else {
console.log("err is ", error);
//login ko, do something else here....
}
});
Once the user is logged in he can load the Documents belonging to a Collection (the SDK automatically manages the Session Token for you):
BaasBox.loadCollection("catalogue", function (res, error) { //catalogue is the name of the Collection
if (res) {
$.each (res, function (i, item) {
console.log("item " + item.id); //.id is a field of the Document
});
} else {
console.log("error: " + error);
}
});
However under the hood the SDK uses JQuery. So you can inspect it to know how to user $.ajax to call BaasBox.
For example the creatUser() method (signup) is:
createUser: function (user, pass, cb) {
var url = BaasBox.endPoint + '/user'
var req = $.ajax({
url: url,
method: 'POST',
contentType: 'application/json',
data: JSON.stringify({
username: user,
password: pass
}),
success: function (res) {
var roles = [];
$(res.data.user.roles).each(function(idx,r){
roles.push(r.name);
})
setCurrentUser({"username" : res.data.user.name,
"token" : res.data['X-BB-SESSION'],
"roles": roles});
var u = getCurrentUser()
cb(u,null);
},
error: function (e) {
cb(null,JSON.parse(e.responseText))
}
});
}
