Initialize the payments library

This is a browser only method. Here we have an example using react. For a full example please refer to payments-nextjs-example

import { useEffect } from "react";
import { Payments } from "@nevermined-io/payments";

export default function Home() {
  const payments = new Payments({
    returnUrl: "http://localhost:8080",
    environment: "staging",
  });

  const onLogin = () => {
    payments.connect();
  };

  useEffect(() => {
    payments.init();
  }, []);

  return (
    <main>
      <div>
        <button onClick={onLogin}>Login</button>
      </div>
    </main>
  );
}
Copy

The init() method should be called immediately after the app returns the user to returnUrl.

Create a subscription

Once the app is initialized we can create a subscription:

async function createSubscription() {
  if (payments.isLoggedIn) {
    const { did } = await payments.createSubscription({
      name: 'test subscription',
      description: 'test',
      price: 10000000n,
      tokenAddress: '0x75faf114eafb1BDbe2F0316DF893fd58CE46AA4d',
      duration: 30,
      tags: ['test'],
    })
  }
}
