wrap-stream

Wrap the output of a stream with a prefix and/or suffix.

Streams2 compliant.

Usage

wrap(pre, post)

Returns a through stream that adds pre before any other output and post after calling stream.end().

var wrap = require('wrap-stream')
var fs = require('fs')

fs.createReadStream(__filename)
  .pipe(wrap('hello', 'world'))
  .pipe(process.stdout)

If you'd prefer not to use either of pre or post, just pass null in its place.

var wrap = require('wrap-stream')
var fs = require('fs')

fs.createReadStream(__filename)
  .pipe(wrap(null, 'lorem ipsum'))
  .pipe(process.stdout)
