Call next when you are ready to consume the next chunk. Optionally you can call next with an error to destroy the stream When the stream ends/errors the callback is called if provided ## License MIT ## Related `stream-each` is part of the [mississippi stream utility collection](https://github.com/maxogden/mississippi) which includes more useful stream modules similar to this one. stream-each-1.2.3/collaborators.md000066400000000000000000000005401332736071100171000ustar00rootroot00000000000000## Collaborators stream-each is only possible due to the excellent work of the following collaborators:
