A simple web3 standard provider that signs sendTransaction payloads.
npm install --save ethjs-provider-signer
const SignerProvider = require('ethjs-provider-signer');
const sign = require('ethjs-signer').sign;
const Eth = require('ethjs-query');
const provider = new SignerProvider('https://ropsten.infura.io', {
signTransaction: (rawTx, cb) => cb(null, sign(rawTx, '0x...privateKey...')),
accounts: (cb) => cb(null, ['0x407d73d8a49eeb85d32cf465507dd71d507100c1']),
});
const eth = new Eth(provider);
eth.sendTransaction({
from: '0x407d73d8a49eeb85d32cf465507dd71d507100c1',
gas: 300000,
data: '0x...',
}, cb);
// results null 0x... (transaction hash)A simple wrapper module for ethjs-provider-http which allows you to sign sendTransaction payloads. It simply takes the sendTransaction data, signs it, and changes the payload method from eth_sendTransaction to eth_sendRawTransaction, then sends the payload.
The signTransaction method is called everytime a payload must be signed. It provides the raw transaction data, a handy raw transaction signing method and a callback to be fired. The callback must return a single signed alphanumeric hex data payload of the signed raw transaction.
ethjs-provider-signer works well with ethjs-signer, a simple module for signing raw transactions. You may also bring your own signer from packages like ethereumjs-signer.
Note, the nonce and gasPrice get auto-filled by default (by using the getTransactionCount and gasPrice RPC calls). However, if these properties are specified in the raw tx object, the raw tx object props will override the default nonce and gasPrice values provided.
