DEPRECATED - narya is now deprecated and no longer maintained. Please follow the official docs to run a local network.

Run an Elrond test network with a single command.

Getting started

Pre-requisites:

• Docker
• Node.js 12 or above

Run it:

$ npx narya

You can install it as a global Node module and run it:

$ npm i -g narya
$ narya

Once the Docker container is up and running the proxy can be accessed at http://localhost:7950

Usage guide

You can use narya via the CLI tool or programmatically in Node.

Note that the docker container is run in auto-remove mode, meaning that as soon narya (or your Node.js that is using it programmatically) exits, the Docker container will also be stopped and removed.

CLI: Command-line tool

To start a local network:

$ npx narya

You can view all commands using help:

$ npx narya help


narya

  Deploy a local Elrond test network. 

Usage

  $ narya [command] [options] 

Commands

  start     Start a network.                                                             
  version   Display version.                                                             
  help      Print this usage guide. Use "help <command>" for help on a specific command. 

Programmatic API

In node.js:

const { start, stop, getChildProcess } = require('narya')

await start() // start a network

const child = getChildProcess() // get the `ChildProcess` instance representing the docker container

await stop() // stop the started network

You can also get a reference to the test account wallets:

const { WALLETS } = require('narya)
const { BasicWallet } = require('elrondjs')

// output Alice's address
console.log( WALLETS.alice.bech32 ) // "erd1qyu5wthldzr8wx5c9ucg8kjagg0jfs53s8nr3zpz3hypefsdd8ssycr6th"

// use it for signing transactions
const wallet = BasicWallet.fromJsonKeyFileString(JSON.stringify(WALLETS.alice), 'password')
await wallet.signTransaction(...)
