stream-from-to

stream-from-to

Utility for piping to/from a stream from a variety of sources to a variety of destinations.

Pass stream-from-to a function that creates a through stream and it'll give you back an object that simplifies the constructon of source and destination streams for piping to/from the through stream.

Usage examples

var streamft = require("stream-from-to")
  , through = require("through")

var mdToHtml = function (filePath) {
  // Through stream that converts markdown to HTML
  return through()
}

streamft(mdToHtml).from.path("/path/to/doc.md").to.path("/path/to/doc.html", function (er) {
    if (er) return console.error(er)
    // Done!
})

With brfs:

var streamft = require("stream-from-to")
  , brfs = require("brfs")

streamft(brfs).from("src/index.js").to("dist/index.js")

to.buffer(opts, cb)

Create a concat-stream and pipe output from the through stream to it. The callback function cb will be invoked when the buffer has been created.
