Convert String to Buffer
To convert a string to a Buffer, you can use the from() method from the global Buffer class in Node.js.
// a string
const str = "Hey. this is a string!";
// convert string to Buffer
const buff = Buffer.from(str, "utf-8");
console.log(buff); // <Buffer 48 65 79 2e ... 72 69 6e 67 21>
- The method accepts a valid string as the first argument.
- and an optional encoding as the second argument.
