Solana Batch Requests

Solana Batch Requests is an npm package that allows you to batch multiple requests to the Solana blockchain, optimizing the number of network calls and improving performance.

Installation

To install the package, use npm, yarn, pnpm, bun, or any other package manager you prefer.

npm install solana-batch-requests

Usage

Fetch Multiple Accounts in a Single Request

import { getParsedAccountInBatch } from 'solana-batch-requests';
import { Connection, PublicKey } from '@solana/web3.js';

const connection = new Connection('https://api.devnet.solana.com', 'confirmed');

const [account1, account2] = await Promise.all([
  getParsedAccountInBatch(connection, new PublicKey('tKeYE4wtowRb8yRroZShTipE18YVnqwXjsSAoNsFU6g')),
  getParsedAccountInBatch(connection, new PublicKey('JDWYBjxEvEWt8yPhdb6BhNerfXaiXogRgUX2yW2AHUVb')),
]);

Note: Although multiple accounts are fetched using two function calls, the library optimizes the process by consolidating these into a single request to the Solana blockchain. This approach significantly reduces network overhead and enhances performance.

Sample with Anchor

Anchor is a powerful framework, but fetching account data typically requires individual requests for each account.

export function FC() {
  // ...
  const program = new Program<IdleGame>(IDL, IDLE_GAME_PROGRAM_ID, provider);

  useEffect(() => {
    const fetchData = async () => {
      const game1 = await program.account.gameData.fetch(gameDataPDA1);
      const game2 = await program.account.gameData.fetch(gameDataPDA2);
      const game3 = await program.account.gameData.fetch(gameDataPDA3);
    };
    fetchData();
  }, [program]);
}

To enhance efficiency, consider fetching multiple accounts in a single request.

import { getParsedAccountInBatch } from 'solana-batch-requests';

export function FC() {
  // ...
  const { connection } = useConnection();
  const program = new Program<IdleGame>(IDL, IDLE_GAME_PROGRAM_ID, provider);

  // Fetch multiple accounts in a single request, improving performance
  useEffect(() => {
    const fetchData = async () => {
      const gameAccounts = await Promise.all([
        getParsedAccountInBatch(connection, gameDataPDA1),
        getParsedAccountInBatch(connection, gameDataPDA2),
        getParsedAccountInBatch(connection, gameDataPDA3),
      ]);
      const gameParseds = gameAccounts.map((acc) => program.coder.accounts.decode("gameData", acc.data));
    };
    fetchData();
  }, [program]);

  useEffect(() => {
    const fetchData = async () => {
      const acc = await getParsedAccountInBatch(connection, gameDataPDA4);
      const gameParsed4 = program.coder.accounts.decode("gameData", acc.data);
    };
    fetchData();
  }, [program]);
}
