I have a file for my Blockchain called gale.js, and I need the Blockchain variable to get into my miner.js file:
let galeCoin = new Blockchain(); // My Blockchain
Can I access this variable from my miner.js file so I can run the minePendingTransactions() function from the Blockchain class
var galeCoin = /* the coin imported from the gale.js file */
var minerAdress = "0xOTUYboIUYEO5C274OUIYGo8isYOCYW6o87TO"; // SHA256 Hash for the miner
while (true) {
minePendingTransactions(minerAdress); // mine (forever)
}
I would also like to access this variable in my user.js file:
var galeCoin = /* the coin imported from the gale.js file */
var userAdress = galeCoin.newAdress(); // A new adress for the user
// I will add the code here later...
And many other files!
But I can't seen to access the variable from the other files! I tried this:
let galeCoin = new Blockchain();
export { galeCoin };
import { galeCoin } from './gale.js'
but that gives me this error when I run miner.js using node miner.js:
node:internal/modules/cjs/loader:936
throw err;
^

I dont understand the error message
I need help as soon as posible!
NOTE: My files are in /Users/Movies/Desktop/devProjects/Blockchain/SecondTry/
Try :
export let galeCoin = new Blockchain();
//add export statement at the beginning of the line where you declare your variable
You can read about it here: https://javascript.info/import-export
Try using the following to import galeCoin from gale.js:
var {galeCoin} = require('./gale.js');
You'll also need to export the galeCoin object from gale.js. You can use the following (append somewhere at the end of gale.js):
module.exports = {galeCoin};
Then you're going to want to run npm install gale.js to ensure that module is added to the node_modules directory. For this you're going to want to make sure the node_modules is in the same director as miner.js. If it is not, npm -g install gale.js.
I should note, I'm assuming you're using node.js, which from the error you threw, seems to be the case.
I hope this was helpful:)
