innerhtml 
Stream content to/from a DOM node
Example
Copy content from one DOM node to another:
index.html
Lorem Ipsum Pellentesque habitant morbi tristique senectus.main.js
var innerhtml = input = document output = document innerhtmlFinally, use browserify to create bundle.js:
npm install -g browserifynpm install innerhtmlbrowserify main.js > bundle.jsAPI
innerhtml.createReadStream(element [, options])
Create a new readable stream whose source is the passed DOM element. If no options are passed, the readable stream will emit element's innerHTML.
options.objectMode
Setting this to true will cause the readable stream to emit a cloned node for each of element's childNodes.
options.remove
Setting this to true will cause the readable stream to empty the contents of element by setting it's innerHTML to "" after it has been emitted.
If objectMode is also set to true, the readable stream will remove and emit each of element's childNodes.
innerhtml.createWriteStream(element [, options])
Create a new writable stream whose destination is the passed DOM element. If no options are passed, the writable stream will replace the element's innerHTML with the content piped to it.
options.objectMode
Setting this to true will cause the writable stream to expect DOM nodes to be written to it.
options.append
Setting this to true will cause the writable stream to append to the existing contents of the node instead of replacing it.
options.clone
When objectMode is set to true, setting this option to true causes the writeable stream to clone the node written to it before it is appended to element. It allows a readable stream to pipe to multiple destinations when in objectMode.
