Calculate file checksum using MD5 in node.js native (start with reading a file).
A bit faster than md5-file under *NIX.
$ npm install --save md5-filexconst md5 = require("md5-filex");
// Async usage
md5.calculate("LICENSE.md", function(err, hash) {
console.log(err, hash);
});
// Sync usage
const hash = md5.calculate("LICENSE.md");
console.log(hash);If no callback passed, it will be called synchronously, otherwise asynchronously.
Compared with md5-file by using ./benchmark/index.js.
md5-filex x 202 ops/sec ±0.42% (80 runs sampled)
md5-file x 183 ops/sec ±1.24% (80 runs sampled)
Machine:
- OS: OSX
- CPU: 2.5 GHz Intel Core i7
- Memo: 16 GB 1600 MHz DDR3
- Disk: 500 GB SSD
A file with 8kb:
md5-filex x 44,972 ops/sec ±0.31% (89 runs sampled)
md5-file x 33,119 ops/sec ±3.51% (81 runs sampled)
A file with 400kb:
md5-filex x 1,112 ops/sec ±0.33% (89 runs sampled)
md5-file x 1,052 ops/sec ±0.49% (88 runs sampled)
HINT: Not that fast under Microsoft Windows.
