Reclaim js-sdk

This README provides a step-by-step guide on integrating the Reclaim Protocol JavaScript SDK into application

Pre-requisites

• An application ID from Reclaim Protocol. You can get one from the Reclaim Developer Protocol

Create a new React application

npx create-react-app reclaim-app
cd reclaim-app

Install the Reclaim Protocol JS-SDK

npm install @reclaimprotocol/js-sdk

Install other dependencies

npm i react-qr-code

Import dependencies

In your src/App.js file, import the Reclaim SDK and the QR code generator

import { useState, useEffect } from 'react'
import { Reclaim } from '@reclaimprotocol/js-sdk'
import QRCode from 'react-qr-code'

Initialize the Reclaim SDK

Declare your application ID and initialize the Reclaim Protocol client. Replace YOUR_APPLICATION_ID_HERE with the actual application ID provided by Reclaim Protocol.

File: src/App.js

import './App.css'
import { useState, useEffect } from 'react'
import { Reclaim } from '@reclaimprotocol/js-sdk'
import QRCode from 'react-qr-code'

function App() {
  const APP_ID = 'YOUR_APPLICATION_ID_HERE'
  const reclaimProofRequest = new Reclaim.ProofRequest(APP_ID)

  return (
    <div className='App'>
      <header className='App-header'>
        <p>Reclaim App</p>
      </header>
    </div>
  )
}

export default App

Implement Verification Request Function

Create functions to handle the verification request. You'll need separate functions for prototype and production modes due to the different handling of the application secret and signature.

Prototype Mode

For testing purposes, use the prototype mode. Note that in production, you should handle the application secret securely on your server.

File: src/App.js

import './App.css'
import { useState, useEffect } from 'react'
import { Reclaim } from '@reclaimprotocol/js-sdk'
import QRCode from 'react-qr-code'

function App() {
  const [requestUrl, setRequestUrl] = useState('')
  const [proofs, setProofs] = useState([])

  const APP_ID = 'YOUR_APPLICATION_ID_HERE'

  const reclaimProofRequest = new Reclaim.ProofRequest(APP_ID)

  async function createVerificationRequest() {
    // id of the provider you want to generate the proof for
    await reclaimProofRequest.buildProofRequest('PROVIDER_ID')

    reclaimProofRequest.setSignature(
      await reclaimProofRequest.generateSignature(
        'YOUR_APPLICATION_SECRET' // Handle securely for production
      )
    )

    const { requestUrl, statusUrl } =
      await reclaimProofRequest.createVerificationRequest()

    await reclaimProofRequest.startSession({
      onSuccessCallback: proofs => {
        console.log('Verification success', proofs)
        setProofs(proofs)
        // Your business logic here
      },
      onFailureCallback: error => {
        console.error('Verification failed', error)
        // Your business logic here to handle the error
      }
    })

    setRequestUrl(requestUrl)
  }

  return (
    <div className='App'>
      <header className='App-header'>
        <p>Reclaim App</p>
        <button
          onClick={createVerificationRequest}
          style={{ marginBottom: '20px', padding: '10px', cursor: 'pointer' }}
        >
          Create Verification Request
        </button>
        <div style={{ backgroundColor: 'white', padding: '10px' }}>
          {requestUrl && (
            <div style={{ backgroundColor: 'white', padding: '10px' }}>
              <QRCode value={requestUrl} />
            </div>
          )}
          {proofs.length > 0 && (
            <div>
              <h3>Proofs</h3>
              <ul>
                {proofs.map((proof, index) => {
                  return (
                    <p key={index}>
                      {JSON.stringify(proof.extractedParameterValues)}
                    </p>
                  )
                })}
              </ul>
            </div>
          )}
        </div>
      </header>
    </div>
  )
}

export default App

Production Mode

In production mode, securely fetch and set the signature from your backend instead of using the application secret directly in the client.

Similar to the prototype mode but ensure to fetch and set the signature securely

async function createVerificationRequestProductionMode() {
  // id of the provider you want to generate the proof for
  await reclaimProofRequest.buildProofRequest('PROVIDER_ID')

  reclaim
    .setSignature
    // TODO: fetch signature from your backend
    // On the backend, generate signature using:
    // await Reclaim.getSignature(requestedProofs, APP_SECRET)
    ()

  const { requestUrl, statusUrl } =
    await reclaimProofRequest.createVerificationRequest()

  await reclaimProofRequest.startSession({
    onSuccessCallback: proofs => {
      console.log('Verification success', proofs)
      setProofs(proofs)
      // Your business logic here
    },
    onFailureCallback: error => {
      console.error('Verification failed', error)
      // Your business logic here to handle the error
    }
  })

  setRequestUrl(requestUrl)
}

Run the application

npm start

Advanced Configuration

You can configure Reclaim SDK to receive proofs in your preferref backend by setting up a callback URL. This is useful if you want to handle the proofs in your backend.

• Set Callback Url - reclaim.setCallbackUrl('https://your-backend.com/receive-proofs')
• Set Status URL - reclaim.setStatusUrl('https://your-backend.com/receive-status')
