** This is the simple light weight application app to understand nodejs loopback framework basics and test its deployment**

You must have already installed Node.js.

Install StrongLoop:

$ npm install -g strongloop

If you run into any issues, see Installing StrongLoop for more information.

Loopback Messaging App is a simple application to understand the Strongloop node js framework. This application provides api for sending messages between registered users. The sender send the message in English language and reciever receives the messages in Spanish language. For message translation Iron Worker is used which again uses Google Translate Api for text conversion.

** NOTE: This app doesn't show any reference for Iron Worker Api or Google Translate Api usage. To understand these you can look my Iron Worker Project **

Start the application back-end by running the following command:

$ cd message-app
$ npm install
$ node . 

To send message you need to set your IRONWORKER credentials, see IRONWORKER CONFIGURATION for more details.

To connect and use any other DB connector you can specify the connector details in server/datasource.local.js file and use the command

$ DB=connector_name node . or DB=connector_name slc run 

• /Messages/recievedByUser Recieve all the messages sent by other Messenger
• /Messages/sendMessage Send message to another user.
• /Messages Get all the messages in database, Only allowed for admin users
• /Messagers Get the list of all the user whom you want to send message
• /Messenger/login allows a Messenger to login
• /Messenger/logout allows a Messenger to logout

You can see some initial users data which are created at app boot time for memory database at server/boot/admin-user.js Sample creates few dummy users and creates a custom user role as admin and makes the first user as admin for the application which has no restrictions in the applications. Note: You can change permissions according to User Roles

This application uses iron_worker_node to make connection to worker. You need to create/edit a iron.json file in the root folder of the project and provide your crerdentials.

After setting your credentials you need to create a worker upload it to hud.iron.io.

Once uploaded you need to specify a url in server/server.js. The url which our worker will use to send back the converted message data back to server.

app.use(function setCurrentUser(req, res, next) {
    .........
    .........
    .........
    .........
    var loopbackContext = loopback.getCurrentContext();
    var loopbackServerUrl = "YOUR SERVER URL ex: myapp.domain.com";
    if (loopbackContext) {
      loopbackContext.set('currentUser', user);
    }
    if(loopbackServerUrl) {
      loopbackContext.set('loopbackServerUrl', loopbackServerUrl);
    }
    ........

Thank you for your interest.

This project was just to understand the basics of Strongoop nodejs framework. There are lot of improvements that can be done. In case of any query or suggestion you can contact me at [email protected].
