hex string to buffer nodejs

To convert a hex string to a buffer in Node.js, you can follow these steps:

1. Start by declaring a variable to store the hex string.
2. Use the Buffer.from() method to convert the hex string to a buffer. Pass the hex string as the first argument and specify the encoding as "hex" in the second argument.
3. The Buffer.from() method will return a buffer object representing the hex string.

Here's an example code snippet to illustrate the steps:

const hexString = "48656c6c6f20576f726c64"; // Example hex string

const buffer = Buffer.from(hexString, "hex");

In this example, the hexString variable holds the hex string "48656c6c6f20576f726c64". The Buffer.from() method is then used to convert the hex string to a buffer object, which is stored in the buffer variable.

Note: Make sure to replace "48656c6c6f20576f726c64" with your actual hex string in the code snippet.
