xrpl

xrpl.js

A JavaScript/TypeScript library for interacting with the XRP Ledger

NPM npm bundle size

This is the recommended library for integrating a JavaScript/TypeScript app with the XRP Ledger, especially if you intend to use advanced functionality such as IOUs, payment paths, the decentralized exchange, account settings, payment channels, escrows, multi-signing, and more.

Features

  • Works in Node.js and in web browsers
  • Helpers for creating requests and parsing responses for the XRP Ledger APIs
  • Listen to events on the XRP Ledger (transactions, ledger, validations, etc.)
  • Sign and submit transactions to the XRP Ledger
  • Type definitions for TypeScript

Requirements

  • Node.js v14 is recommended. We also support v12 and v16. Other versions may work but are not frequently tested.

Getting Started

In an existing project (with package.json), install xrpl.js:

$ npm install --save xrpl

Or with yarn:

$ yarn add xrpl

Example usage:

const xrpl = require("xrpl")
async function main() {
const client = new xrpl.Client("wss://s.altnet.rippletest.net:51233")
await client.connect()

const response = await client.request({
"command": "account_info",
"account": "rPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe",
"ledger_index": "validated"
})
console.log(response)

client.disconnect()
}
main()

Using xrpl.js with create-react-app

To use xrpl.js with React, you need to install shims for core NodeJS modules. Starting with version 5, Webpack stopped including shims by default, so you must modify your Webpack configuration to add the shims you need. Either you can eject your config and modify it, or you can use a library such as react-app-rewired. The example below uses react-app-rewired.

  1. Install shims (you can use yarn as well):

    npm install --save-dev \
    assert \
    buffer \
    crypto-browserify \
    https-browserify \
    os-browserify \
    process \
    stream-browserify \
    stream-http \
    url
  2. Modify your webpack configuration

    1. Install react-app-rewired

      npm install --save-dev react-app-rewired
      
    2. At the project root, add a file named config-overrides.js with the following content:

      const webpack = require('webpack');

      module.exports = function override(config) {
      const fallback = config.resolve.fallback || {};
      Object.assign(fallback, {
      "assert": require.resolve("assert"),
      "crypto": require.resolve("crypto-browserify"),
      "http": require.resolve("stream-http"),
      "https": require.resolve("https-browserify"),
      "os": require.resolve("os-browserify"),
      "stream": require.resolve("stream-browserify"),
      "url": require.resolve("url"),
      "ws": require.resolve('xrpl/dist/npm/client/WSWrapper'),
      })
      config.resolve.fallback = fallback
      config.plugins = (config.plugins || []).concat([
      new webpack.ProvidePlugin({
      process: 'process/browser',
      Buffer: ['buffer', 'Buffer']
      })
      ])

      // This is deprecated in webpack 5 but alias false does not seem to work
      config.module.rules.push({
      test: /node_modules[\\\/]https-proxy-agent[\\\/]/,
      use: 'null-loader',
      })
      return config;
      }
    3. Update package.json scripts section with

      "start": "react-app-rewired start", 
      "build": "react-app-rewired build",
      "test": "react-app-rewired test",

Using xrpl.js with React Native

If you want to use xrpl.js with React Native you will need to install shims for core NodeJS modules. To help with this you can use a module like rn-nodeify.

  1. Install dependencies (you can use yarn as well):

    npm install react-native-crypto
    npm install xrpl
    # install peer deps
    npm install react-native-randombytes
    # install latest rn-nodeify
    npm install [email protected] --dev
  2. After that, run the following command:

    # install node core shims and recursively hack package.json files
    # in ./node_modules to add/update the "browser"/"react-native" field with relevant mappings
    ./node_modules/.bin/rn-nodeify --hack --install
  3. Enable crypto:

    rn-nodeify will create a shim.js file in the project root directory. Open it and uncomment the line that requires the crypto module:

    // If using the crypto shim, uncomment the following line to ensure
    // crypto is loaded first, so it can populate global.crypto
    require('crypto')
  4. Import shim in your project (it must be the first line):

import './shim'
...

Using xrpl.js with Deno

Until official support for Deno is added, you can use the following work-around to use xrpl.js with Deno:

import xrpl from 'https://dev.jspm.io/npm:xrpl';

(async () => {
const api = new (xrpl as any).Client('wss://s.altnet.rippletest.net:51233');
const address = 'rH8NxV12EuV...khfJ5uw9kT';

api.connect().then(() => {
api.getBalances(address).then((balances: any) => {
console.log(JSON.stringify(balances, null, 2));
});
});
})();

Mailing Lists

We have a low-traffic mailing list for announcements of new xrpl.js releases. (About 1 email per week)

If you're using the XRP Ledger in production, you should run a rippled server and subscribe to the ripple-server mailing list as well.
