Simple conversion of files to base64

convertFileToBase64.js

// MacOS agents in Azure don't come with base64 installed, so we use node to convert our p8 file to base64 so we can use it in the deployment task
const fs = require("fs");

// 0 is node
// 1 is location of this file
const filePath = process.argv[2];

if (!filePath) {
  throw new Error("no file path given");
}

if (!fs.existsSync(filePath)) {
  throw new Error("no such file: " + filePath);
}

const buffer = fs.readFileSync(filePath);

console.log(buffer.toString("base64"));
