Package Exports
- stream-equal
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (stream-equal) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
node-stream-equal 
Test that two readable streams are equal to each other.
Usage
var streamEqual = require('stream-equal');
var fs = require('fs');
var readStream1 = fs.createReadStream(file);
var readStream2 = fs.createReadStream(file);
streamEqual(readStream1, readStream2, function(err, equal) {
console.log(equal); // true
});Motive
Useful for testing. This method is faster and uses much less memory than buffering entire streams and comparing their content, specially for bigger files.
You could also get the hash sum of a stream to test it against another stream. But that would take up more CPU due to the hashing and would require the entire streams to be read if they are not equal.
API
streamEqual(readStream1, readStream2, callback(err, equal))
Will compare each data event on both streams, pausing when needed to keep them in sync. equal will be either true or false if there is no err.
