I am trying to do
sendrawtransaction <transaction_hex>
from nodejs
using bitcoin-core package
i did
npm install bitcoin-core --save
i already have latest bitcoind
setup and running with rpcusername
and rpcpassword
are set in bitcoin.conf
my current code looks like this.
const Client = require('bitcoin-core');
const client = new Client({ username: 'adminuser', password : 'adminpassword'});
client.getInfo((error, help) => console.log(help));
i have managed to only get response from getInfo
everything else gives either empty output
or undefined
or null
so far i have tried many variations like these
tx_hex = "0200000001949e0e3ac02fef76dffa8e2191ee0041f71a90c5ec9bbcba77db5f57e49fe6dd010000006b483045022100d6ac8520a1cfe80f6f3c2fbe6c3f903894203715928382e77c3c7ad0de74112502203c14601e5195dde88c9cc16c45dc273af168bd4fd03b6c045f832b7ba0134f8c012102183e719a510ff322fcb0dbfa279ef2500dd87c0b8c6184480846262e1949fbebfeffffff028bec0900000000001976a9141b0c5cb82d59cb2e07e8d5e343167fda48a9d60e88ace2920f00000000001976a9148108670170211830be2c3c557afe6bc2205d27de88ac864a0700"
client.sendRawTransaction((tx_hex,response) => console.log(response));
client.sendRawTransaction((tx_hex) => console.log());
client.sendRawTransaction((tx_hex), function(){console.log()});
but none of the above gives confirmation, or gives proper output.
what am i missing here ?
i mean if i were to do this using bitcoin-cli
on terminal it returns txhash
.
e.g.
[root@localhost deploy]# bitcoin-cli sendrawtransaction 0200000001949e0e3ac02fef76dffa8e2191ee0041f71a90c5ec9bbcba77db5f57e49fe6dd010000006b483045022100d6ac8520a1cfe80f6f3c2fbe6c3f903894203715928382e77c3c7ad0de74112502203c14601e5195dde88c9cc16c45dc273af168bd4fd03b6c045f832b7ba0134f8c012102183e719a510ff322fcb0dbfa279ef2500dd87c0b8c6184480846262e1949fbebfeffffff028bec0900000000001976a9141b0c5cb82d59cb2e07e8d5e343167fda48a9d60e88ace2920f00000000001976a9148108670170211830be2c3c557afe6bc2205d27de88ac864a0700

client.sendRawTransaction((tx_hex,response) => console.log(tx_hex + ':' + response));
returns
