node-stream-equal
Test that two readable streams are equal to each other.
Usage
const streamEqual = require('stream-equal');
const fs = require('fs');
let readStream1 = fs.createReadStream(file);
let readStream2 = fs.createReadStream(file);
let equal = await streamEqual(readStream1, readStream2);
Motive
Useful for testing. This method of comparing is faster and uses 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. Which is similar to what this library does, without the hashing.
API
async streamEqual(readStream1, readStream2)
A function that compares each data
event on both streams, pausing when needed to keep them in sync. Returns a proimse that resolves to either true
or false
.
Install
