hashNode

• Use crypto.createHash() to create a Hash object with the appropriate algorithm.
• Use hash.update() to add the data from val to the Hash, hash.digest() to calculate the digest of the data.
• Use setTimeout() to prevent blocking on a long operation, and return a Promise to give it a familiar interface.

const crypto = require("crypto");

const hashNode = (val) =>
  new Promise((resolve) =>
    setTimeout(
      () => resolve(crypto.createHash("sha256").update(val).digest("hex")),
      0
    )
  );
Examples;
hashNode(JSON.stringify({ a: "a", b: [1, 2, 3, 4], foo: { c: "bar" } })).then(
  console.log
);
