There are actually a lot of similar packages, but I always think they are too complicated. Maybe a small and simple core package will be more suitable for those original projects.
npm i simple-blockchain-rpc
const { Client } = require("simple-blockchain-rpc");
const rpcClient = new Client({
rpchost: 'Your rpc host',
rpcport: Your rpc port,
rpcuser: 'Your rpc username',
rpcpassword: 'Your rpc password',
})
rpcClient.call('getblockhash', [100]).then(result => {
console.log(result)
