Datalayer
Data Layer
The Data Layer is the only component you, as the client, must implement. This layer stores and manages credential data securely within your infrastructure. The Client-Gateway communicates with the Data Layer over HTTP.
Responsibilities
Your implementation should support the following operations:
Create: Add a new credential to the database.
Import: Import an existing credential from external systems.
Revoke: Mark a credential as revoked.
Verify: Validate the status of a credential.
Example Implementation
You can implement the Data Layer using any database technology. Below is an example using MongoDB.
Setting Up MongoDB
Install MongoDB on your infrastructure or use a managed service.
Create a
credentials
collection.
Example Code
Here is an example of a simple Node.js service for the Data Layer:
const express = require('express');
const mongoose = require('mongoose');
const app = express();
app.use(express.json());
const CredentialSchema = new mongoose.Schema({
credential_id: String,
name: String,
type: String,
status: String,
expires_at: Date,
});
const Credential = mongoose.model('Credential', CredentialSchema);
app.post('/create', async (req, res) => {
const credential = new Credential(req.body);
await credential.save();
res.status(201).json({ success: true });
});
app.listen(5000, () => console.log('Data Layer service running on port 5000'));
Client should setup the datalayer URL on dashboard in order to gateway forward requests to the Data Layer for processing.
