xrpl

xrpl.js

A JavaScript/TypeScript library for interacting with the XRP Ledger

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

• Connect to a rippled server from Node.js or a web browser
• Helpers for creating requests and parsing responses for the rippled API
• 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. Other versions may work but are not frequently tested.
• npm is recommended. yarn may work but we use package-lock.json.

Getting Started

See also: RippleAPI Beginners Guide

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

$ npm install xrpl

Then see the documentation.

Using xrpl.js with React Native

If you want to use xrpl.js with React Native you will need to have some of the NodeJS modules available. To help with this you can use a module like rn-nodeify.

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

   npm install react-native-crypto
   npm install xrpl
   # install peer deps
   npm install react-native-randombytes
   # install latest rn-nodeify
   npm install rn-nodeify@latest --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).RippleAPI({ server: '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)

• Subscribe to ripple-lib-announce

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.

• Subscribe to ripple-server

Development

To build the library for Node.js and the browser:

$ npm run build

The TypeScript compiler will output the resulting JS files in ./dist/npm/.

webpack will output the resulting JS files in ./build/.

For details, see the scripts in package.json.

Running Tests

Unit Tests

1. Clone the repository
2. cd into the repository and install dependencies with npm install
3. npm test

Linting

Run npm run lint to lint the code with eslint.

Generating Documentation

Update the documentation by running npm run docgen.
