Optional: Cloud9 Development Environment

Create your account

Make your free account with Cloud9 here. I found the easiest way to make a new account is to use the GitHub Account Creation tool found at the top of the page.

Setup your workspace

1. Name and describe your new workspace
2. Fork HospitalRun to your own repository in GitHub or elsewhere
3. Clone HospitalRun from your own repository using the Clone from Git field
4. Select Node.js from the Choose a template field to finish setting up your workspace

Run the setup script

Open up a terminal in your cloud9 workspace. Make sure you are in the default directory (~/workspace). Next, source the cloud9 setup script by running: source ./script/setupcloud9 Because of how nvm works in the cloud9 workspace, the script must be sourced. The script will setup nodejs to the correct version, install all the dependencies, setup couchdb and run the tests. The process takes about 25 minutes to run. When you are finished, the project will be ready to run.

Start Ember app

To start the ember app run ember serve --live-reload-port 8082. This will start the hospitalrun application on the default preview port 8080 with the live reload server running on port 8082.

The application should be accessible now at https://hospitalrun-frontend-[YOUR-C9-USERNAME].c9users.io

If your application fails to load or respond to login, verify that the url has been made public. From the IDE click the share button in the top right corner. Check the boxes to make 'Application' and 'Files' public.

Running CouchDB

The setup script will start CouchDB automatically. However if you need to run CouchDB in the future, use the following command: sudo su couchdb -c /usr/bin/couchdb. To test if CouchDB is running, run curl http://127.0.0.1:5984. Use the sudo command every time you launch CouchDB, or the Ember app will fail to load.

Update dependencies

Each time you work on this project, you're probably going to want to update your fork from HospitalRun's master. To do this, you need to set up HospitalRun as the upstream repository to your personal origin repo. Use this guide from GitHub for help on using forks correctly.
For your dependencies to work properly, they will need to be updated every time the package information is changed. To update them, run npm install and bower install from the root of your workspace.

Access to Futon through Cloud 9

Since Cloud9 only opens ports 8080, 8081, and 8082, you'll need a work around to view the GUI for CouchDB. Save the following code as /home/ubuntu/workspace/c9-couch.js:

var http = require('http');
function onRequest(req,res) {
    var postData = '';
    req.addListener("data", function(postDataChunk) {
        postData += postDataChunk;
    });
    req.addListener("end", function() {
        makeCouchRequest(req.url, req.method, postData, function(cdata, ct) {
            res.writeHead(200, {
                'Content-Type': ct
            });
            res.end(cdata);
        });
    });        
};
function makeCouchRequest(url,method,data, cb){
    var req = http.request({
        host: process.env.COUCHIP || "127.0.0.1",
        port: process.env.COUCHPORT || 5984,
        path: url,
        method: method
    },function(response){
        var str='';
        response.on('data', function(chunk){
            str += chunk;
        });
        response.on('end', function(){
            cb(str,response.headers['content-type']);
        });
        
    });
    req.write(data);
    req.end();
};
var server = http.createServer(onRequest); console.log('c9couch server created'); server.listen(process.env.PORT || 3000, process.env.IP || "0.0.0.0", function(){
  var addr = server.address();
  console.log("c9couch server listening at", addr.address + ":" + addr.port);
});

To access this webpage, make sure couchdb is running (see above) and run node c9-couch.js. Then navigate to the page by going to https://-.c9users.io/_utils/ but do not forget to end the address with a slash!
