Usage

Documentation is in progress, refer to the examples below

Initializing with configuration

const SmartIDAuth = require('smartid-auth');
const smartauth = new SmartIDAuth({
  host: 'https://sid.demo.sk.ee/smart-id-rp/v1',
  requestParams: {
    relyingPartyUUID: '00000000-0000-0000-0000-000000000000',
    relyingPartyName: 'DEMO',
    certificateLevel: 'QUALIFIED'
  },
/*

  Optionally, you can pass some configuration options for axios requests:

  http: {
    httpsAgent: new https.Agent(....),
    proxy: {
      ...
    },
  },
*/
});

Usage Example 1 - Session resolves only when successful result (OK) from Smart-ID service:

When you only care about successful Smart-ID login and you're going to show only "Login failed" no matter what happened. In this example, you don't need to worry about checking the result status yourself.

try {
  const session = await smartauth.authenticate(
    'EE', // country
    '12345678901', // personal ID number
    'Hello World' // message to display on Smart-ID mobile app
  );

  // This is the verification code you should display to the user (i.e. on your website):
  console.log('Verification code: ' + session.verificationCode);

  console.log('Waiting for user action...');

  // getResponse(true) = only "OK" session end result code is valid, all other cases throw error
  const response = await session.getResponse(true);
  console.log('Authentication OK!');
  // full Smart-ID response:
  console.log(response.data);
  // Certificate subject (name, country, id number):
  console.log(response.subject);
} catch (err) {
  console.error('Authentication failed');
  console.error(err);
}

Usage Example 2 - Session resolves with any result (OK, USER_REFUSED, TIMEOUT, etc):

When you need more customization depending on actual end result. For example, to be able to show why login failed. In this example you need to check the end result yourself and decide what to do in each case.

try {
  const session = await smartauth.authenticate(
    'EE', // country
    '12345678901', // personal ID number
    'Hello World' // message to display on Smart-ID mobile app
  );

  // This is the verification code you should display to the user (i.e. on your website):
  console.log('Verification code: ' + session.verificationCode);

  console.log('Waiting for user action...');

  // getResponse(false) = all session end result codes are returned
  const response = await session.getResponse();
  // full Smart-ID response:
  console.log(response.data);

  if (response.result === 'OK') {
    console.log('Authentication OK!');
    // Certificate subject (name, country, id number):
    console.log(response.subject);
  } else {
    console.log('Authentication failed!:');
    switch (response.result) {
      case 'USER_REFUSED':
        console.error('User refused the request');
        break;
      case 'TIMEOUT':
        console.error('Authentication request timed out');
        break;
      case 'DOCUMENT_UNUSABLE':
        console.error('Request cannot be completed');
        break;
      case 'WRONG_VC':
        console.error('User chose wrong verification code');
        break;
      default:
        console.error(`Unknown result: ${response.result}`);
    }
  }
} catch (err) {
  console.error('Authentication error');
  console.error(err);
}

Session response object (result of session.getResponse)

{
  result: String, one of: 'OK' / 'USER_REFUSED' / 'TIMEOUT', 'DOCUMENT_UNUSABLE', 'WRONG_VC',
  data: Object, Raw response from Smart-ID service (https://github.com/SK-EID/smart-id-documentation/blob/master/README.md#464-response-structure),
  subject: Object, x509 certificate subject field { countryName, surName, givenName, serialNumber, commonName }
}

Output example

$ npm run demo EE 10101010005
Verification code: 8865
Waiting for user action...
Authentication OK!
{ countryName: 'EE',
  surname: 'SMART-ID',
  givenName: 'DEMO',
  serialNumber: 'PNOEE-10101010005',
  commonName: 'SMART-ID,DEMO,PNOEE-10101010005',
  organizationalUnitName: 'AUTHENTICATION' }

Running tests

Smart-ID provides test accounts for automated testing. Running npm run test will go through those:

EndResult	Country	national-identity-number	certificateLevel
OK	EE	10101010005	QUALIFIED
OK	LV	010101-10006	QUALIFIED
OK	LT	10101010005	QUALIFIED
USER_REFUSED	EE	10101010016	QUALIFIED
USER_REFUSED	LT	10101010016	QUALIFIED
