@carnesen/bitcoin-config-cli

A Node.js command-line interface (CLI) for bitcoin server software configuration

Install

npm install --global @carnesen/bitcoin-config-cli

^^ This installs this package to your global node_modules area. Probably you can now invoke this CLI from anywhere using the command bitcoin-config. If not you'll need modify your PATH.

Usage

By default this CLI reads/writes the default bitcoin configuration file location, e.g. ~/.bitcoin/bitcoin.conf on Linux.

The CLI can take a JSON-serialized configuration object and write it as an INI-serialized string as expected by the bitcoin server software:

$ bitcoin-config write --json '{"regtest": true, "daemon": true}'

Let's check the contents of the configuration file:

$ bitcoin-config read --format ini
# This is a bitcoin configuration file written using @carnesen/bitcoin-config

# Run this node on its own independent test network.
regtest=1

# Spawn bitcoin as a background process
daemon=1

Looks good! Now suppose later we want to update a configuration file with a specific value:

$ bitcoin-config set --acceptnonstdtxn 1

The "set" command preserves existing values and adds the one(s) specified:

$ bitcoin-config read
{ regtest: true, daemon: true, acceptnonstdtxn: true }

By now there are a TON of available bitcoin configuration options:

$ bitcoin-config set --help
Usage: bitcoin-config set <options>

Options:

   [--acceptnonstdtxn <str>] : Relay and mine non-standard transactions
                               Allowed values {'0', '1'}
   [--addresstype <str>] : p2sh-segwit, legacy, or bech32
   [--addnode <str0> [...]] : Add a node IP address to attempt to connect to
   [--addrmantest <str>] : allows you to test address relay locally
                           Allowed values {'0', '1'}
   [--alertnotify <str>] : Execute a command when an alert or long fork is received.
                           "%s" in the command string is replaced by the alert message.
...

Usage as a library

In addition to providing a CLI, this npm package can also be used as a library in conjunction with @carnesen/cli:

import { bitcoinConfig } from '@carnesen/bitcoin-config-cli';
import { branch, cli } from '@carnesen/cli';

export const root = branch({
  commandName: 'awesome',
  subcommands: [bitcoinConfig],
})

if (module === require.main) {
  cli(root)();
}
