Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

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.

// Reference: https://github.com/solana-developers/pirate-bootcamp/blob/14e7313fbdfffc63e0a42744e6be708c2b7a38a0/quest-6/idle-game/app/src/components/Game.tsx#L145
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]);
}
