Welcome to the world of decentralized identity management! In this blog, we will walk you through using 3ID Connect, a powerful tool that allows seamless user account management via a browser iframe. Whether you’re building applications that require user authentication or managing decentralized identities, this guide will help you get started quickly.

What is 3ID Connect?

3ID Connect is an intuitive interface that provides user account management. It leverages the functionality of ThreeIdProvider to allow users to authenticate, manage, link, and permission their 3ID keys. With an easy integration process and a robust architecture, it simplifies how developers interact with decentralized identities.

Getting Started

To ease your journey into using 3ID Connect, let’s dive into the installation and basic usage.

Installation

• Run the following command in your terminal:

npm install @3idconnect

Basic Usage

Here’s a simple way to authenticate using 3ID Connect:

• First, import the necessary modules:

import { EthereumAuthProvider, ThreeIdConnect } from '@3idconnect'

• Now, create an auth provider with the Ethereum address:

const authProvider = new EthereumAuthProvider(ethProvider, addresses[0])

• Then, initialize the 3ID Connect instance and connect:

const threeIdConnect = new ThreeIdConnect()

await threeIdConnect.connect(authProvider)

Understanding 3ID Connect – An Analogy

Think of 3ID Connect as a highly organized librarian in a vast library of decentralized identities. Just like the librarian helps visitors find the right book, 3ID Connect helps users access and manage their identities within a digital space. It leverages a special system (Ethereum) to identify each user (like a library card) and aids in connecting them to various sections of the library (different applications) while ensuring their privacy and security. Each interaction with the librarian is documented for accountability, similar to how the app communicates with 3ID Connect through an RPC layer.

Development Setup

If you’re looking to dive deeper into development, follow these prerequisites and installation steps:

Prerequisites

• You need Yarn v1 and Lerna v4 installed globally:

npm install -g lerna yarn

Installation Steps

• Run the following command from the root folder:

yarn install

• This will install all dependencies and build the necessary packages.

Available Scripts

In the root folder, you can use various scripts to assist in development:

• lint: lints all apps and packages
• build: builds all packages
• test:unit: runs unit tests
• test:management: runs integration tests for the management library with a Ceramic server
• test:integration: runs integration tests from the integration app with a Ceramic server

Troubleshooting

While working with 3ID Connect, you may occasionally face challenges. Here are some troubleshooting ideas:

• If you’re experiencing installation errors, ensure that your Node.js version is compatible with Yarn and Lerna.
• For authentication issues, double-check that your Ethereum address is correct and that you’re connected to the right provider.
• If the iframe isn’t loading correctly, verify your application’s settings and ensure that CORS is configured appropriately.
