npm-package-near-async-block

Utilities for fetching NEAR Protocol block data via the mainnet RPC.

Installation

npm install npm-package-near-async-block

Functions

• getBlock(blockId) — Fetch a single block by height, hash, or finality string
• getBlockRange(startHeight, endHeight) — Fetch multiple consecutive blocks
• getBlockChunks(blockId) — Get all chunks for a block
• getFinalBlockHeight() — Get the current final block height
• waitForBlock(targetHeight) — Poll until a target block height is reached
• getBlockTransactions(blockId) — Get all transactions in a block

Usage

import { getBlock, getBlockRange, getBlockChunks, getFinalBlockHeight, waitForBlock, getBlockTransactions, } from "npm-package-near-async-block";

// Fetch by finality const finalBlock = await getBlock("final"); const latestBlock = await getBlock("latest");

// Fetch by height or hash const block = await getBlock(12345678);

// Fetch a range of blocks const blocks = await getBlockRange(12345678, 12345690);

// Get chunks for a block const chunks = await getBlockChunks(12345678);

// Get the current final block height const height = await getFinalBlockHeight();

// Wait until a specific block height is reached await waitForBlock(12345700);

// Get all transactions in a block const txs = await getBlockTransactions(12345678);

Notes

• All requests target https://rpc.mainnet.near.org
• getBlockRange fetches blocks in parallel; avoid very large ranges
• getBlock("latest") maps to optimistic finality on the RPC
