Just to note I do not know Javascript at all, I can script in PS/BATCH but that is my limit and even then it’s basic stuff.
Through google efforts I’ve ended up with what I want (decode Base58 string to HEX) but from two separate scripts, the first script outputs the results (byte array) to a file which I then manually copy/paste to the second script/section to convert it to HEX but if I could just pass those results as a variable to the next script/section and combine as a single script without outputting anything to file that would be great.
1st Script:
const bs58 = require('bs58');
const fs = require('fs');
b = bs58.decode('5P1mhvZrHosrH5svDZh78xH9JaSxzhnW9zMb9FRbFM2yH5yqq2udFN1FoaiiJTTUfEpeEP5hT71RX94w7RTkZ2ef');
j = new Uint8Array(b.buffer, b.byteOffset, b.byteLength / Uint8Array.BYTES_PER_ELEMENT);
//output to a file - i want this output to go to the 2nd function
fs.writeFileSync('mykey.json', `[${j}]`);
2nd Script:
const toHexString = (bytes) => {
return Array.from(bytes, (byte) => {
return ('0' + (byte & 0xff).toString(16)).slice(-2);
}).join('');
};
//this array is what is output to the mykey.json file in the first script and i manually copy here
const byteArr = new Uint8Array([219,13,41,199,3,152,117,230,42,93,161,161,35,176,217,140,122,241,213,53,238,36,223,12,247,137,86,221,44,92,14,196,70,16,156,255,115,52,6,147,205,90,73,83,208,179,47,215,149,229,12,61,49,59,25,114,67,190,24,7,53,126,167,156]);
console.log(toHexString(byteArr));
Please note that the original string is a private key for a wallet, it is purely a test wallet that contains no funds and never will.
I tried commenting out the writeFileSync line and passing the ‘j’ in various ways to the next section as a variable for the array but I’m failing miserably.

If you just need to pass
j
into yourtoHexString()
function, you can combine the code into one file like below.I have removed the references to the filesystem, and the second
Unit8Array
cast, as you shouldn’t need to call that function again ifj
is already the output of that function.
