bip136js
A javascript library for encoding and decoding BIP 136 TxRefs. This package passes all test cases from the spec.
This library goes beyond the spec to attempt to decode TxRefs that have had the Human-Readable Part (HRP) stripped off but are otherwise valid.
Installation
npm i bip136
Usage
import * as bip136 from 'bip136';
// decodes TxRefs with separators
bip136.decode('tx1:r29u-mqjx-putt-3p0');
// { network: 'mainnet', blockHeight: 456789, txIndex: 1234 }
// decodes TxRefs without separators
bip136.decode('TX1R29UMQJXPUTT3P0');
// { network: 'mainnet', blockHeight: 456789, txIndex: 1234 }
// decodes TxRefs with invalid characters
bip136.decode('tx1!r29u/mqj*x-putt^^3p0');
// { network: 'mainnet', blockHeight: 456789, txIndex: 1234 }
// decodes TxRefs with outpoints
bip136.decode('tx1:y7ll-llll-lpqq-s4qz-hw');
// { network: 'mainnet', blockHeight: 16777215, txIndex: 32767, outpoint: 1 }
// decodes TxRefs with the HRP stripped off
bip136.decode('xz8e-kyyp-qmff-zyt');
// { network: 'testnet', blockHeight: 2470513, txIndex: 36 }
// encodes TxRefs
bip136.encode({
blockHeight: 709635,
txIndex: 60,
});
// 'tx1:rxq2-tpup-q0nd-lah'
