JavaScript Conflux Software Development Kit
npm install js-conflux-sdk

JavaScript Conflux Software Development Kit is a complete library for interacting with the Conflux Blockchain Core Space in both Node.js and browser environment.
Featured with:
* Full support of Conflux Network Core Space's JSON-RPC API
* Wallet management
* Meta-classes create JavaScript objects from any contract ABI, including ABIv2 and Human-Readable ABI
* Unit(CFX, Drip) conversion
* Common utilities:
1. Address conversion
2. ABI/RLP encoding/decoding
3. Crypto utilities
4. Type conversion
* Extensive documentation and examples
For the Conflux eSpace JS SDK, consider using one of the following robust libraries: ethers.js, viem, or web3.js
* js-conflux-sdk documentation
* SDK API doc
* Examples
* Community examples
* Fullnode JSONRPC API
* Public RPC Provider Endpoints
* Testnet faucet
* Core Space Documentation
* FAQs
Install through npm
``sh`
npm install js-conflux-sdk
Use in Node.js script
`javascript
const { Conflux } = require('js-conflux-sdk');
const conflux = new Conflux({
url: 'https://test.confluxrpc.com',
networkId: 1, // Note: network is required
logger: console, // for debug
});
`
require deep nested file/dir
`javascript`
const util = require('js-conflux-sdk/src/util');
#### umd
The front-packed package is located in js-conflux-sdk's dist folder.
`javascript`
import { Conflux } from 'js-conflux-sdk/dist/js-conflux-sdk.umd.min.js';
or if your bundler supports the browser field in package.json
`javascript`
import { Conflux } from 'js-conflux-sdk';
or
`html`
From v2.0 the exported root class to browser window name changed from Conflux to TreeGraph
Or you can use public CDN links:
* jsdelivr
After importing the package, you can use the Conflux class instance to interact with the Conflux network, such as querying the balance of an account, sending a transaction.
`javascript
const { Conflux, Drip } = require('js-conflux-sdk');
const conflux = new Conflux({
url: 'https://test.confluxrpc.com',
networkId: 1, // Note: network is required
logger: console, // for debug
});
const exampleAddress = 'cfxtest:aar8jzybzv0fhzreav49syxnzut8s0jt1a1pdeeuwb';
async function main() {
const balance = await conflux.cfx.getBalance(exampleAddress);
console.log(Balance of ${exampleAddress} is ${Drip(balance).toCFX()} CFX);
const account = await conflux.wallet.addPrivateKey(process.env.PRIVATE_KEY); // prepare and set your private key as environment variable
const txHash = await conflux.cfx.sendTransaction({
from: account.address,
to: exampleAddress,
value: Drip.fromCFX(1), // send 1 CFX
});
console.log(Transaction hash: ${txHash});
// after the transaction is executed, you can query the receipt, and the receiver should have 1 CFX more
}
main().catch(console.error);
`
For more guides and examples, please refer to the SDK documentation.
To gain an address conversion(hex->base32 or reverse) performance boost, you can install @conflux-dev/conflux-address-rust in your project. Which will be used to replace the purejs version and can gain a 10-100 performance boost.
Note: @conflux-dev/conflux-address-rust required a rust environment to install.
How to know SDK's version
`js`
const { Conflux } = require('js-conflux-sdk');
const conflux = new Conflux({
url: 'https://test.confluxrpc.com',
networkId: 1,
});
console.log(conflux.version);
// 2.0.0
How to know fullnode's version
`js``
const clientVersion = await conflux.cfx.getClientVersion();
console.log(clientVersion);
// conflux-rust-2.0.0
