I need to get data of a block using the block height.

Is there a javascript library to get block data from the Bitcoin blockchain, by connecting to local running node or a 3rd party blockchain provider?

  • What exact data do you need from the block? Would a simple API call to e.g. blockchain.info be enough? – 0xb10c Apr 24 '18 at 18:43
  • @0xb10c Specifically, I want to pull all the transactions that are included in a block. I don't want to be dependent on a third party api provider. It would be better if I could connect to the blockchain by using the js library and query the blockchain directly. – varun Apr 25 '18 at 9:04

bitcoin tools library https://github.com/bitpay/bitcore-lib

Unofficial Node.js client for blockexplorer.com API https://github.com/barto-/blockexplorer

or you can install bitcore full node and use bitcore-lib with that full node

  • Thanks. I'm using the Bitcoin-Core library, which makes it easy to execute bitcoin-cli commands by simply formatting them to camel case. – varun Apr 26 '18 at 12:05
