Example snippets of using the Subtopia JS SDK.

Subscriptions

Purchasing a subscription:

import {
  SubtopiaClient,
  SubtopiaRegistryClient,
  ChainType,
  SUBTOPIA_REGISTRY_ID
} from "subtopia-js-sdk";
// ...  your code

const subtopiaClient = await SubtopiaClient.init({
  algodClient: PUT_ALGOD_INSTANCE_HERE,
  chainType: PUT_CHAIN_TYPE_ENUM_HERE // 'testnet'|'mainnet'|'localnet'
  productID: PUT_PRODUCT_ID_HERE,
  registryID: SUBTOPIA_REGISTRY_ID(ChainType.{YOUR_CHAIN_TYPE_HERE}),
  creator: { addr: PUT_WALLET_ADDRESS, signer: PUT_WALLET_SIGNER },
});

const response = await subtopiaClient.createSubscription(
  { subscriber: { addr: PUT_WALLET_ADDRESS, signer: PUT_WALLET_SIGNER } },
);

console.log(response.txID); // response is of type string

// ... rest of your code
Copy

Subscription lookup:

// ... your code
const subscriptionRecord = await subtopiaClient.getSubscription({
  subscriberAddress: PUT_SUBSCRIBER_ADDRESS,
  algodClient: PUT_ALGOD_INSTANCE_HERE,
});

// SubscriptionRecord (throws Error if not subscribed)
console.log(subscriptionRecord);
// ... rest of your code
Copy

Unsubscribing:

// ... your code
const deleteResult = await subtopiaClient.deleteSubscription({
  subscriber: {
    addr: PUT_SUBSCRIBER_ADDRESS,
    signer: PUT_SUBSCRIBER_SIGNER,
  },
  subscriptionID: PUT_SUBSCRIPTION_ID,
});

// Transaction ID of the unsubscribe transaction
console.log(deleteResult.txID);
// ... your code
Copy

Transfering subscription:

// ... your code
const transferResult = await subtopiaClient.transferSubscription({
  oldSubscriber: {
    addr: PUT_OLD_SUBSCRIBER_ADDRESS,
    signer: PUT_OLD_SUBSCRIBER_SIGNER,
  },
  newSubscriberAddress: PUT_NEW_SUBSCRIBER_ADDRESS,
  subscriptionID: PUT_SUBSCRIPTION_ID,
});

// Transaction ID of the transfer transaction
console.log(transferResult.txID);
// ... your code
Copy

  algodClient: PUT_ALGOD_INSTANCE_HERE,
  creator: { addr: PUT_WALLET_ADDRESS, signer: PUT_WALLET_SIGNER },
  chainType: PUT_CHAIN_TYPE_HERE,
});

const discount = await subtopiaRegistryClient.createDiscount({
  discountType: PUT_DISCOUNT_TYPE_HERE, // number - the type of discount to apply. FIXED or PERCENTAGE
  discountValue: PUT_DISCOUNT_VALUE_HERE, // number - the discount to be deducted from the subscription price
