JavaScript SDK for RSS3-Hub

Compatible with v0.3.1 of RSS3 protocol

Install

yarn add rss3

import RSS3 from 'rss3';

Usage

Initialization

There are 4 ways to initialize the sdk

• Initialize with external signature method (recommended)
• create a brand new account
• Initialize with mnemonic
• Initialize with private key

For security reasons, unless there is a specific need, you should initialize with external signature method provided by the wallet or secure device.

And agentSign is a kind of agent signature, its principle can refer to the agent_id and agent_signature field in RSS3 protocol, the function is that the user only needs to sign when the first change, subsequent changes use agent signature, only need to save the agent information in a suitable and save place through the agentStorage parameter, the default behavior is saved in the cookie

interface IOptions {
    endpoint: string; // RSS3 network endpoint
    agentSign?: boolean;
    agentStorage?: {
        set: (key: string, value: string) => Promise<void>;
        get: (key: string) => Promise<string>;
    };
}

export interface IOptionsMnemonic extends IOptions {
    mnemonic?: string;
    mnemonicPath?: string;
}

export interface IOptionsPrivateKey extends IOptions {
    privateKey: string;
}

export interface IOptionsSign extends IOptions {
    address: string;
    sign: (data: string) => Promise<string>;
}

new RSS3(options: IOptionsMnemonic | IOptionsPrivateKey | IOptionsSign);

Example:

MetaMask or other ethereum compatible wallet

ethers

import RSS3 from 'rss3';
import { ethers } from 'ethers';

const provider = new ethers.providers.Web3Provider(window.ethereum);
const signer = provider.getSigner();

const rss3 = new RSS3({
    endpoint: '',
    address: await signer.getAddress(),
    sign: async (data) => await signer.signMessage(data),
});

web3.js

import RSS3 from 'rss3';

    endpoint: '',
    address,
    sign: async (data) => await web3.eth.personal.sign(data, address),
});
