requestCreateEvent

Usage

connect() must be called and connection session must be initiated.

The requestCreateEvent() function requests the creation of an onchain transaction from a user.

We use the term “event” rather than “transaction” because not all onchain transactions are financial in nature.

Here are the event types you can request creation for:

enum EventType {
  Deploy = 'Deploy',
  Execute = 'Execute',
  Send = 'Send',
  Join = 'Join',
  Split = 'Split',
  Shield = 'Shield',
  Unshield = 'Unshield'
}

Here is the request payload you need to define:

type CreateEventRequestData = {
  address?: string;
  network?: Network;
  type: EventType;
  programId: string;
  functionId: string;
  fee: number;
  feeRecord?: RecordWithPlaintext;
  inputs: (RecordWithPlaintext | string)[];
  tokenIds?: string[];
  settlementInfo?: {
    eventId?: string;
    expectedRecordCount: number;
    currentRecordCount: number;
  };
};

import { requestCreateEvent } from '@puzzlehq/sdk-core';
import { EventType } from '@puzzlehq/types';
import { useState } from 'react';

function CreateEventPage() {
  /// your specific function inputs go in here!
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<string | undefined>();
  const [eventId, setEventId] = useState<string | undefined>();

  const onClick = async () => {
    setLoading(true);
    const createEventResponse = await requestCreateEvent({
      type: EventType.Execute,
      programId: 'program_name_here.aleo',
      functionId: 'function_name_here',
      fee: 1.23,
      inputs: ['123u64']
    });
    if (createEventResponse.error) {
      setError(createEventResponse.error);
    } else {
      setEventId(createEventResponse.eventId);
    }
    setLoading(false);
  };

  return (
    <div>
      <button
        onClick={ onClick }
        disabled={ loading }
      >
        create event
      </button>
      { eventId && <p>event pending: {eventId}</p> }
      { error && <p>error creating event: {error}</p> }
    </div>
  );
}

Types
