Enface Pay +ID authorization Node.js library

Enface offers secure, blockchain based authorization feature for any websites (or apps) using Enface Pay +ID application. Our authentication process is based on strong cryptographic algorithms and are military safe.

To enable our solution you should pass the following steps:

• Register for free at Enface website, visit �Biometric authorization�page and click on the �Add new project� button. Setup �API key for authentication� from the drop-down of the project panel. Copy the �Project id� and �Secret key� variables for future usage.
• Integrate the frontend widget on your website or application.
• Setup backend environment, using instructions below.

This package is for backend integration with Node.js environment. You should provide any existing Express instance to enable EnfaceAuth.

Installation

npm

npm i --save enface-auth-node-enfaceid

yarn

yarn add enface-auth-node-enfaceid

Usage

ES2015 module import:

import { EnfaceAuth } from "enface-auth-node-enfaceid";

CommonJS module require:

const { EnfaceAuth } = require("enface-auth-node-enfaceid");

Initialization:

new EnfaceAuth({

  httpServer: <object>,
  callbackUrl: <string>,
  projectId: <string>,
  secretCode: <string>,
  fields: <string>,
  debug: <boolean>, // debug logs

});

EnfaceAuth parameters:

httpServer (Express instance)

EnfaceAuth module will start in HTTP/S mode and will use default Express port to listen all the connections. In this mode both frontend widget and Enface API server should be able connect to http(s)://yourdomain.com to process required operations.

callbackUrl: <string>

http(s) URL to connect to this backend module.

projectId: <string>

�Project id� variable from the Enface website project description.

secretCode: <string>

�Secret key� variable from the Enface website project description.

fields: <string>

The data fields, you want to request from a user during authorization process (separated by commas). The available values are: 'full_name', 'email', 'phone_mobile'. For example, to request full information about the user, 'fields' variable should be set to 'full_name,email,phone_mobile'. You can ommit the 'fileds' variable, and will receive only user login in Enface ID platform.

Here is how EnfaceAuth is integrated at our own Node.js server.

new EnfaceAuth({

  httpServer: app, // app is the existing Express instance
  projectId: process.env.AUTH_PRODUCT_ID,
  secretCode: process.env.BIO_AUTH_SECRET,
  callbackUrl: 'https://enface-api-server.herokuapp.com',

});
