How to Get All Token Accounts by Authority

You can fetch token accounts by owner. There are two ways to do it.

Get All Token Account

import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
import { TOKEN_PROGRAM_ID } from "@solana/spl-token";

(async () => {
  // connection
  const connection = new Connection("http://127.0.0.1:8899", "confirmed");

  const owner = new PublicKey("G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY");
  let response = await connection.getParsedTokenAccountsByOwner(owner, {
    programId: TOKEN_PROGRAM_ID
  });

  response.value.forEach((accountInfo) => {
    console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
    console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
    console.log(
      `owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`
    );
    console.log(
      `decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`
    );
    console.log(
      `amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`
    );
    console.log("====================");
  });
})();

Filter By Mint

import { TOKEN_2022_PROGRAM_ID } from "@solana/spl-token";
import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";

(async () => {
  // connection
  const connection = new Connection(
    clusterApiUrl("http://127.0.0.1:8899"),
    "confirmed"
  );

  const owner = new PublicKey("G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY");
  const mint = new PublicKey("54dQ8cfHsW1YfKYpmdVZhWpb9iSi6Pac82Nf7sg3bVb");

  let response = await connection.getParsedTokenAccountsByOwner(owner, {
    mint: mint,
    programId: TOKEN_2022_PROGRAM_ID
  });

  response.value.forEach((accountInfo) => {
    console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
    console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
    console.log(
      `owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`
    );
    console.log(
      `decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`
    );
    console.log(
      `amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`
    );
    console.log("====================");
  });
})();
