Installation

Current version 1.4.0

//npm
npm install @cryptr/cryptr-react

//npm
yarn add @cryptr/cryptr-react

Configuration

CryptrConfig

Here is an example of a configuration that will be necessary to implement our solution

const config = {
  audience: process.env.REACT_APP_CRYPTR_AUDIENCE,
  cryptr_base_url: process.env.REACT_APP_CRYPTR_BASE_URL,
  tenant_domain: process.env.REACT_APP_CRYPTR_TENANT_DOMAIN,
  client_id: process.env.REACT_APP_CRYPTR_CLIENT_ID,
  default_redirect_uri: process.env.REACT_APP_CRYPTR_DEFAULT_REDIRECT_URI,
  dedicated_server: process.env.REACT_APP_CRYPTR_DEDICATED_SERVER == 'true',
  default_slo_after_revoke: process.env.REACT_APP_CRYPTR_DEFAULT_SLO_AFTER_REVOKE == 'true',
}

Explanation of config

key	Required/Optional	type	Default	Description
tenant_domain	required	string slug	-	Reference to your company entity
client_id	required	uuid	-	Reference to your front app id
audience	required	string URL	-	Root URL of your front app
default_redirect_uri	required	string URL	-	Desired redirection URL after authentication process
cryptr_base_url	required	string URL	-	URL of your Cryptr service
default_slo_after_revoke	required(since 1.2.0)	boolean		Defines if SLO has to be done on SSO logout process
dedicated_server	Optional	boolean	false	Contact Cryptr Team to set properly

⚠️ fixed_pkce has been removed in the 1.4.0 release version

Cryptr Provider

After creating your config, create your CryptrProvider that should encapsulate your App content.

Here is a quick sample (also see our sample (src/examples/App.tsx))

import React, { ReactElement } from 'react'
import { BrowserRouter as Router, Route } from 'react-router-dom'

// import from cryptr SDK
import { CryptrProvider } from '@cryptr/cryptr-react'

const config = {/*... your config */}

const AppContainer = (): ReactElement => {
  return (
    <Router>
      // your routes
    </Router>
  )
}

const App = (): ReactElement => {
  <CryptrProvider {...config} >
    <AppContainer />
  </CryptrProvider>
}

return default App

Then you will be able to handle Cryptr session through our hook and our components

Cryptr Hook useCryptr

On any React element child of the CryptrProvider you'll be able to use our hook useCryptr for your Cryptr usage.

Here is a quick example

import React, { ReactElement } from 'react'
import { useCryptr } from '@cryptr/cryptr-react'

const MyComponent = (): ReactElement => {
  const { isAuthenticated, isLoading } = useCryptr()

  if (isLoading) {
    return <span>Cryptr is processing authentication</span>
  }

  if (isAuthenticated()) {
    return <span>A Cryptr session is live</span>
  } else {
    return <span>User is not authenticated</span>
  }
}

export default MyComponent

Here is a quick list of tools from our hook

Name	Purpose
isLoading	Cryptr SDK is currently looking for a active authentication (after login or refresh)
isAuthenticated	Cryptr SDK has a live Access token ➡️ a user is logged in
user	Returns the user objecgt containing all keys from Cryptr ID Token
logOut	Asks to Cryptr SDK to run the session log out process
decoratedRequest(axiosConfig: AxiosRequestConfig)	This method based on axios will decorate the request to the desired endpoint with the current Access Token as Authorization Bearer Header

There are more but the major features are just above

Components

We embedded some components in this SDK to help your integration. Mainly it's button components and can still be configured as you wish (eg: text, className, style ...)

SignInWithDomainButton

When you either know which is the entity of the user trying to connect or if you prefer to let him type his email on our gateway

import React, { ReactElement } from 'react'
import { SignInWithDomainButton } from '@cryptr/cryptr-react'

const LoginComponent = (): ReactElement => {
  return <SignInWithDomainButton domain={'nullable-entity-domain'} />
}

export default LoginComponent

💡 domain is optional if you do not know current user's context

SignInWithEmailButton

When you already asked the user his email address

import React, { ReactElement } from 'react'
import { SignInWithEmailButton } from '@cryptr/cryptr-react'

const LoginComponent = (): ReactElement => {
  return <SignInWithEmailButton email={'not-nullable-john@doe.com'} />
}

export default LoginComponent

Deprecations

Some legacy items have been deleted since 1.3.0. If you need some support for migration contact us
