While making a Shopify App with Node.js, I had to convert a string into base64.
Initially, I tried to use the btoa() function available in JavaScript, but I got a "btoa is not defined" error in Node.js. Turns out it's not available.
So if you want to encode a string into base64 in Node.js, do the following instead:
Buffer.from('YOUR STRING HERE').toString('base64')
That will give you back the base64 version.
