Create an HTTP and WebSocket firefose from anything!
Create a firefose from anything!
Creating a firehose for your data can be a daunting propect. You can create one fairly simply, but there are alot of other factors to take into accont.
These services, by their very nature, are long lived processes. Any errors will affect all customers connected. I (OllieParsley) have experience handling the Twitter firehose and also developing the DataSift HTTP Streaming API, which behaves in a similar way to the Twitter Streaming API
npm install firehose
git clone firstname.lastname@example.org:ollieparsley/node-firehose.git
The firehose server is made up of a few big components. These can mostly be combined in anyway to customise the ways a user connects and authenticates with the server.
Transports are the different communication methods you have with the user. In the examples directory you will find a ready made HTTP Transport component
Included in this module are:
It is really easy to customise how users are authenticated. This takes care of extracting credentials from a request. The default authentication doesn't check any credentials. In the examples directory you will find a Basic Authentication component.
Once the firehose server has grabbed credentials (if any) they are passed along to a store and expects a User object in response. The default Store returns a randomly generated user. In the examples directory you can find a JSON Store which has all users stored in a JSON file.
Routers are used to make sure the path specified in a request is correct. The default router allows all requests through.
Arguably the most important component. This is the element that receives your own data and passes it to users. The fake source sends a bit of JSON every 2 seconds.
You can create your components by extending our base classes. Check out the examples directory for how to do this. Essentially you include our base class for a component and extend any of the methods using prototype inheritance.
