## ethjs-provider-signer
A simple web3 standard provider that signs sendTransaction payloads.
## Install
```
npm install --save ethjs-provider-signer
```
## Usage
```js
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)
```
## About
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.
