npm install @did-connect/storage
// or

const { BaseStorage } = require('@did-connect/storage');
const keystone = require('keystone');

module.exports = class KeystoneStorage extends BaseStorage {
  constructor() {
    this.model = keystone.list('sessions').model;
  }

  create(sessionId, attrs) {
    const LoginToken = this.model;
    const item = new LoginToken({ sessionId, ...attrs });
    return item.save();
  }

  read(sessionId) {
    return this.model.findOne({ sessionId });
  }

  update(sessionId, updates) {
    return this.model.findOneAndUpdate({ sessionId }, updates);
  }

  delete(sessionId) {
    return this.model.remove({ sessionId });
