node-sse-reader

reads a text/event-stream stream as specified by the WD-eventsource W3C recommendation

Installation

npm install --save sse-reader

Usage

var Reader = require('sse-reader');
var reader = Reader();
source.pipe(reader);

The following stream

: comment this!
data: Hello

event: add
data: Floby

id: 8000
event: remove
data: Floby

results in the following events being triggered

'event' -> ('Hello')
'data'  -> ({data: 'Hello'})
'event' -> ('Floby', 'add')
'event:add'   -> ('Floby')
'data'  -> ({name: 'add', data: 'Floby'})
'event' -> ('Floby', 'remove', '8000')
'event:remove'-> ('Floby')
'id'    -> ('8000')
'data'  -> ({id: '8000', name: 'remove', data: 'Floby'})
'end'   -> ()

The data event of course come from the basic readable stream interface which means you can also call .read() and pipe().

Test

You can run the tests with npm test. You will need to know mocha
