+# buffer-writer
+
+[![Build Status](https://secure.travis-ci.org/brianc/node-buffer-writer.png?branch=master)](http://travis-ci.org/brianc/node-buffer-writer)
+
+Fast & efficient buffer writer used to keep memory usage low by internally recycling a single large buffer.
+
+Used as the binary protocol writer in [node-postgres](https://github.com/brianc/node-postgres)
+
+Since postgres requires big endian encoding, this only writes big endian numbers for now, but can & probably will easily be extended to write little endian as well.
+
+I'll admit this has a few postgres specific things I might need to take out in the future, such as `addHeader`
+
+## api
+
+`var writer = new (require('buffer-writer')());`
+
+### writer.addInt32(num)
+
+Writes a 4-byte big endian binary encoded number to the end of the buffer.
+
+### writer.addInt16(num)
+
+Writes a 2-byte big endian binary encoded number to the end of the buffer.
+
+### writer.addCString(string)
+
+Writes a string to the buffer `utf8` encoded and adds a null character (`\0`) at the end.
+
+### var buffer = writer.addHeader(char)
+
+Writes the 5 byte PostgreSQL required header to the beginning of the buffer. (1 byte for character, 1 BE Int32 for length of the buffer)
+
+### var buffer = writer.join()
+
+Collects all data in the writer and joins it into a single, new buffer.
+
+### var buffer = writer.flush(char)
+
+Writes the 5 byte postgres required message header, collects all data in the writer and joins it into a single, new buffer, and then resets the writer.
+
+## thoughts
+
+This is kind of node-postgres specific.  If you're interested in using this for a more general purpose thing, lemme know.
+I would love to work with you on getting this more reusable for your needs.
