FEAT: Implement Starknet event parsers #54

[Cevedale]

Hey!
You may need to adapt it based on your specific needs and the details of the Starknet API:

// src/starknet/parser.ts

class Contract {
private address: string;
private abi: any; // replace 'any' with the actual type of ABI

constructor({ address, abi }: { address: string, abi: any }) {
this.address = address;
this.abi = abi;
}

eventFilter(eventName: string): any {
// Implement your logic to generate the DNA filter based on the event name
// This is just a placeholder, replace it with the actual logic
const filter = {
fromAddress: "...",
// ... other filter properties
};
return filter;
}

eventParser(eventData: any): any {
// Implement your logic to parse the event data into TypeScript objects
// This is just a placeholder, replace it with the actual logic
const parsedData = {
// ... parsed data properties
};
return parsedData;
}
}

export default Contract;

test file:
// packages/indexer/test/parser.test.ts

import Contract from '../src/starknet/parser';

describe('eventFilter', () => {
it('returns the DNA filter', () => {
const contract = new Contract({ address: 'your_contract_address', abi: {} /* your ABI here */ });
const filter = contract.eventFilter('Transfer');
expect(filter).toMatchInlineSnapshot({ fromAddress: "...", ... });
});
});

describe('eventParser', () => {
it('parses event data into TypeScript objects', () => {
const contract = new Contract({ address: 'your_contract_address', abi: {} /* your ABI here / });
const parsedData = contract.eventParser({/ your sample event data here /});
expect(parsedData).toMatchInlineSnapshot({ / expected parsed data structure */ });
});
});

Replace 'your_contract_address', {} /* your ABI here */, and other placeholders with the actual values and data structures based on your Starknet contract and ABI.

This is a basic starting point, and you may need to adjust it based on the actual structure of Starknet events and contracts.

@Cevedale is this still open for contribution?

Yes this one is available! Can you join the Apibara @ OD Hack telegram group to discuss it?
