SMART-ID Node typescript client for version 2

This is a Node client for the SMART-ID API version 2.

Important

• Note that this package is in early development.
• The API for this package is subject to change.

Updates

Version 0.0.4 - To provide flexibility, added two new methods that can be used separately from the initial authenticateWithPNO.

• createAuthData - Creates the hash and verification code for the authentication request. You can store and use them later to trigger actual authentication flow using triggerAuth.
• triggerAuth - Triggers the actual authentication flow using the hash and verification code created by createAuthData.

Installation

pnpm install @reixtech/smartid-ts

Usage

Create smartid client

import {
    createSmartIDClient,
    makeAllowedInteractionsBuilder,
} from '@reixtech/smartid-ts';

// Helper function to create allowed interactions.
// Keep in mind that duplicate interactions are not allowed and will throw an error.
const allowedInteractionsOrder = makeAllowedInteractionsBuilder()
    .add(
        'confirmationMessageAndVerificationCodeChoice',
        'Message to display in the Smart-ID app.',
    )
    .add('confirmationMessage', 'Message to display in the Smart-ID app.')
    .add('verificationCodeChoice', 'Message to display in the Smart-ID app.')
    .build();

const smartIdClient = createSmartIDClient(
    {
        // URL of the Smart-ID API
        host: 'https://sid.demo.sk.ee/smart-id-rp/v2',
        // UUID of the relying party
        relyingPartyUUID: '00000000-0000-0000-0000-000000000000',
        // Name of the relying party
        relyingPartyName: 'DEMO',
        // Allowed interactions
        allowedInteractionsOrder,
    },
);

Authenticate with personal identification code and PIN callback

import {
    createSmartIDClient,
    makeAllowedInteractionsBuilder,
    isEndResultError,
    isRequestError,
} from '@reixtech/smartid-ts';

// ... create smartid client

try {
    const response = await smartIdClient.authenticateWithPNO(
        {
            // Country code for person (EE, LT, LV)
            countryCode: 'EE',
            // National identity number for person
            nationalIdentityNumber: '39303292707',
        },
        async (pin) => {
            // You can use this callback to show the verification code to the user
            // once this promise resolves, then actual request is sent to the users phone.
            // Without it Smart ID app will popup a dialog before user can see the verification code.
            await new Promise((resolve) => setTimeout(resolve, 5000));
        },
    );
    
    // You can use the response to do something with the authentication result
    console.log('Authentication response:', response);
} catch (e) {
    if (isEndResultError(e)) {
        // Error is now in the form of EndResultError
        // Triggered when the user cancels the request, or the request times out etc
    }

    if (isRequestError(e)) {
        // Error is now in the form of RequestError
        // Triggered when the request to the API fails, NOT FOUND, UNDER MAINTENANCE, etc.
    }
    
    // Handle other errors
    // Like certificate validation errors, etc.
}

Create authentication data and trigger authentication request separately

import {
    createSmartIDClient,
    makeAllowedInteractionsBuilder,
    isEndResultError,
    isRequestError,
} from '@reixtech/smartid-ts';

// ... create smartid client

try {
    const { hash, verificationCode, randomBytes, identifier } =
        smartIdClient.createAuthData({
            countryCode: 'EE',
            nationalIdentityNumber: '39303292707',
        });

    // Show the verificationCode to user and do any magic you like...

    // ...

    // Trigger the authentication request using previously generated data.

    const { parsedSubject, response } = await smartIdClient.triggerAuth({
        hash,
        randomBytes,
        identifier,
    });

    // Do something with the parsedSubject and response...
} catch (e) {
    if (isEndResultError(e)) {
        // Error is now in the form of EndResultError
        // Triggered when the user cancels the request, or the request times out etc
    }

    if (isRequestError(e)) {
        // Error is now in the form of RequestError
        // Triggered when the request to the API fails, NOT FOUND, UNDER MAINTENANCE, etc.
    }
    
    // Handle other errors
    // Like certificate validation errors, etc.
}
