--- title: "StreamHelper API" layout: default section: api --- A `StreamHelper` can be viewed as a pausable stream with some helper methods. It is not a full featured stream like in nodejs (and can't directly used as one) but the exposed methods should be enough to write the glue code with other async libraries : `on('data', function)`, `on('end', function)` and `on('error', function)`. It starts paused, be sure to `resume()` it when ready. If you are looking for an asynchronous helper without writing glue code, take a look at `accumulate(function)`.
