ra-cognito-auth's Introduction

ra-cognito-auth

AWS Cognito auth provider for react-admin.

Installation

npm install ra-cognito-auth amazon-cognito-identity-js-promises aws-jwt-verify

Usage

Basic usage

Build auth provider and pass it to the react admin.

Example:

import { CognitoUserPool } from 'amazon-cognito-identity-js-promises';
import { buildCognitoAuthProvider } from 'ra-cognito-auth';
import jsonServerProvider from 'ra-data-json-server';
import { Admin, ListGuesser, Resource } from 'react-admin';

const dataProvider = jsonServerProvider('https://jsonplaceholder.typicode.com');

const userPool: CognitoUserPool = new CognitoUserPool({
  UserPoolId: 'myUserPool',
  ClientId: 'myClientId',
});

const authProvider = buildCognitoAuthProvider({ userPool });

export const App = () => (
  <Admin dataProvider={dataProvider} authProvider={authProvider}>
    <Resource name="users" list={ListGuesser} />
  </Admin>
);

Get access token from the cognito pool to authorize api calls:

// calling `getSession()` will also refresh token if needed
const session = await userPool.getCurrentUser()?.getSession();
const accessToken = session?.getAccessToken().getJwtToken();

Usage with verifying JWT

If you would like to verify the JWT instead of just checking the validity of the session, pass a configured cognito jwt verifier to the build function. The JWT token from the session is then verified against the verifier during the checkAuth method of the provider.

Example with validating if the user has an admin group:

// ...

const cognitoJwtVerifier = CognitoJwtVerifier.create({
  tokenUse: 'access',
  userPoolId: 'myUserPool',
  clientId: 'myClientId',
  groups: ['admin'],
});

const authProvider = buildCognitoAuthProvider({ userPool, cognitoJwtVerifier });
