Install

Install through npm

$ npm install js-conflux-sdk

How to import

Nodejs

Use in Node.js script

const { Conflux } = require('js-conflux-sdk');

const conflux = new Conflux({
  url: 'https://test.confluxrpc.com',
  networkId: 1,
  logger: console, // for debug
});

require deep nested file/dir

const util = require('js-conflux-sdk/src/util');

Frontend

umd

The front packed package is located in js-conflux-sdk's dist folder.

import { Conflux } from 'js-conflux-sdk/dist/js-conflux-sdk.umd.min.js';

or if your bundler supports the browser field in package.json

import { Conflux } from 'js-conflux-sdk';

or

<script type="text/javascript" src="node_modules/js-conflux-sdk/dist/js-conflux-sdk.umd.min.js"></script>
<script type="text/javascript">
  const conflux = new window.TreeGraph.Conflux({
    url: 'https://test.confluxrpc.com',
    logger: console,
    networkId: 1,
  });
</script>

From v2.0 the exported class to browser window name change from Conflux to TreeGraph

Or you can use public CDN links:

• jsdelivr

Address conversion performance

To gain a address conversion(hex->base32 or reverse) performance boost, you can install @conflux-dev/conflux-address-rust in your project. Which will be used to relace the purejs version and can gain a 10-100 performance boost.

Note: @conflux-dev/conflux-address-rust required a rust environment to install.
