Usage

1. Use the cloudpipe module to generate a base64-encoded payload string:

   Note: This will require the use of npm link as the cloudpipe module is not available on npmjs yet

   index.js:

   var cloudpipe = require('cloudpipe');
   
   var pipe = cloudpipe.init({
     url: 'http://192.168.59.103:8000/v1',
     username: 'admin',
     apiKey: '12345'
   });
   
   var add = function(x, y, callback) {
     callback(null, x + y);
     return 17;
   };
   
   var cloudAdd = pipe.create(add);
   cloudAdd(2, 4, function(err, result) {
     // err == null
     // result == 6
     console.log(result);
   });

   $ node index.js | python -mjson.tool | grep stdin | awk -F\" '{print $4}'

2. Base-64 decode the string output in the previous step:

   Note: this requires the base64 program, available as part of the coreutils package.

   $ payload=$(echo 'eyJmIjoiXyQkTkRfRlVOQyQkX2Z1bmN0aW9uICh4LCB5LCBjYWxsYmFjaykge1xuICBjYWxsYmFjayhudWxsLCB4ICsgeSk7XG4gIHJldHVybiAxNztcbn0iLCJvcHRpb25zIjp7fSwiYXJncyI6eyIwIjoyLCIxIjo0LCIyIjoiXyQkTkRfRlVOQyQkX2Z1bmN0aW9uIChlcnIsIHJlc3VsdCkge1xuICAvLyBlcnIgPT0gbnVsbFxuICAvLyByZXN1bHQgPT0gNlxuICBjb25zb2xlLmxvZyhyZXN1bHQpO1xufSJ9fQ==' | base64 --decode)

3. Pipe the payload over STDIN to the runner:

   $ echo $payload | ./bin/runner.js --result-file /tmp/.result

4. Confirm that 6 was output on STDOUT and /tmp/.result contains 17.
