Calculating Nonce for Raw Transactions in Geth

Here is the code to calculate the transaction nonce for raw transactions in Ethereum’s geth client.

function getNonce(address, callback) {
    web3.eth.getTransactionCount(address, function(error, result) {
        var txnsCount = result;
        web3.currentProvider.sendAsync({
            method: "txpool_content",
            params: [],
            jsonrpc: "2.0",
            id: new Date().getTime()
        }, function(error, result) {
            if (result.result.pending) {
                if (result.result.pending[address]) {
                    txnsCount = txnsCount +
                        Object.keys(result.result.pending[address]).length;
                    callback(null, txnsCount);
                } else {
                    callback(null, txnsCount);
                }
            } else {
                callback(null, txnsCount);
            }
        })
    })
}

Make sure you have tx_pool API enabled.

    To create code blocks or other preformatted text, indent by four spaces:

        This will be displayed in a monospaced font. The first four
    spaces will be stripped off, but all other whitespace
    will be preserved.
    
    Markdown is turned off in code blocks:

    To create not a block, but an inline code span, use backticks:

    Here is some inline `code`.
