Internet Identity Integration

This repo is a forkable example designed to help you seamlessly implement Internet Identity authentication into your projects.

Getting Started

1. Clone or Fork the Repository

git clone https://github.com/your-username/internet-identity-integration.git
cd internet-identity-integration

2. Prerequisites

Ensure you have the following installed:

• Node.js
• Internet Computer SDK (IC SDK)

3. Install Dependencies

npm install

4. Start the Local DFX Replica

Run the following command to start your local Internet Computer replica:

dfx start --clean --background

Note: Take note of the port the replica is running on, e.g., Replica API running on 127.0.0.1:8080.

5. Create the Internet Identity Canister

dfx canister create internet_identity --specified-id rdmx6-jaaaa-aaaaa-aaadq-cai

6. Deploy Canisters

This will create and deploy the backend, frontend, and Internet Identity canisters:

dfx deploy

7. View the Application

After deployment, you can view the application at:

• http://127.0.0.1:8080/?canisterId=yourcanisterid
• http://yourcanisterid.localhost:8080/

Testing the Integration

1. Run the application:

   • Open your browser and go to:
     • http://127.0.0.1:8080/?canisterId=yourcanisterid
     • http://yourcanisterid.localhost:8080/

2. Click "Login" to authenticate via Internet Identity.

3. Verify your principal appears after successful login.

If you encounter ECONNREFUSED 127.0.0.1:4943 or a similar error, modify the code to use the port number specified in your Replica API running on 127.0.0.1:8080.

Happy building with Internet Identity!
