Javascript Quickstart

Steps to getting started with Appbase

1. Add Appbase library to your codebase and set the app credentials as they appear here.

   <script src="cdn.appbase.io/appbase.js"></script>
   

   Appbase.credentials('aphrodite', '4d8d0072580912343cd74aa0015cd217')
   

2. Now let’s create two Appbase references under namespaces “user” and “tweets”.

   var userRef = Appbase.create("user", "lara")
   var tweetRef = Appbase.create("tweet")
   

   As seen here, one can optionally specify the reference name.

3. Now we will set some data on these references.

   userRef.setData({
     status: "sudo",
     location: "Belo Horizonte, Brazil"
   });
   tweetRef.setData({
     message: "Remember Red, hope is a good thing."
   });
   

4. Now let’s add the tweet as an edge to our user reference.

   userRef.setEdge(tweetRef, 'tweeted')
   

5. Go real-time! Listen to the changes on the user reference data properties and edges, to see the changes we have made so far.

   userRef.on('properties', function(error, ref, userSnap) {
       console.log(userSnap.properties().status)
       console.log(userSnap.properties().location)
   })
   
   userRef.on('edge_added', function(error, edgeRef, eSnap) {
           edgeRef.on('properties', function(error, ref, tweetSnap) {
               console.log(tweetSnap.properties().message)
           })
   })
