Here's a basic example demonstrating how to integrate ZarinPal using easypay.js with an Express.js application:

import express, { Request, Response } from "express";
import { getPaymentDriver, ZarinPalDriver } from "easypay.js";

const app = express();

app.listen(3000);

const zarinPalDriver: ZarinPalDriver = getPaymentDriver("zarinpal");
zarinPalDriver.setToken("your-zarinpal-token");

const AMOUNT = 100000;

app.post("/payment/checkout", async (req: Request, res: Response) => {
  const result = await zarinPalDriver.request(
    {
      amount: AMOUNT,
      callback_url: "http://localhost:3000/payment/checkout/cb",
      description: "test description",
    },
    false,
  );

  if (result.isError) {
    res.status(500).json({
      success: false,
      message: result.error.message,
      errCode: result.error.code,
      validations: result.error.validations,
    });
  } else {
    res.status(200).json({
      success: true,
      messsage: result.data.message,
      url: result.data.url,
    });
  }
});

app.get("/payment/checkout/cb", async (req: Request, res: Response) => {
  const Status = String(req.query.Status);
  if (Status === "OK") {
    const verifyResult = await zarinPalDriver.verify({
      amount: AMOUNT,
      authority: String(req.query.Authority),
    });

    if (verifyResult.isError) {
      res.status(400).json({
        success: true,
        message: verifyResult.error.message, // or custom message
        code: verifyResult.error.code,
      });
    } else {
      res.status(200).json({
        success: true,
        verifyResult,
      });
    }
  } else {
    res.status(400).json({ success: false, message: "canceled" });
  }
});

console.log(`Server running on port: 3000`);
