Disclaimer

The intention of this is largely to serve as a reference rather than a true import or application. This is by design a small component that composes larger systems which are orchestrated by some higher level mechanism. For example containerizing with Docker and deploying and managing the container cluster(s) with Kubernetes. The plan is to eventually provide an example of such an deployment as I open source enough components to perform some useful and cool actions. Towards this end, the orchestration example may prove more directly applicable once available; or at the very least more complete examples of how one might want to create and manage a micro-service-like environment.

Twitter Service

Introduction

Twitter is a small service that provides a means of accessing a subset of Twitter REST and Streaming APIs through rpc requests. This could be extended to support the entire Twitter API by design, though plans to add functionality is on a need-by-need basis.

The RPC framework is provided by grpc as implemented in Go. As consequence the underlying rpc encoding used is Protocol Buffers.

The service implementation provides both a means of starting the service and performing operations on the service at runtime. See Usage for details.

To deploy this service, you will need to provide either Twitter User Authentication for full support, or Application-only authentication if you only plan on performing twitter search calls. See Twitter OAuth for more details on how to acquire these credentials. The service takes these details in from a file, the following is the format of the file along with required fields:

{ 
"Config": {
  "ConsumerKey": "",
  "ConsumerSecret": "",
}
"Token":{
  "Token":"",
  "TokenSecret":"",
},
}

Install

go get -v bitbucket.org/jvulic/twitter

Usage

Starting the service.

twitter start // Start the default Twitter service
twitter start --certd="cert" // Start the Twitter service sourcing service certificates from cert/
twitter start --twcred=creds.json // Start the Twitter service sourcing 'creds.json' for Twitter API credentials
twitter start --loglevel=0 // Start the Twitter service at DEBUG logging level
twitter start --port=1337 // Start the Twitter service listening on port 1337

Performing operations on a running service.

// Search for tweets containing 'shrek' using the Twitter service located at
// address :1337 with logging level DEBUG.
twitter search "shrek" --target=":1337" --loglevel=0

// Access the Twitter's Streaming API searching for tweets containing 'shrek'
// 'ogre' using the service located at address :1337 with logging level DEBUG.
twitter stream "shrek,ogre" --target=":1337" --loglevel=0

Details about each operation, there supported flags, and anything else just add the -h flag.
