About

Wrap a single page react application with the AuthCodeProvider component to easily handle authentication with an OAuth2 server using Authorization Code flow for all pages, using just a few lines of code.

AuthCodeProvider can also be added to individual pages or react components to only require authentication for particular areas of an application.

A set of functions included in AuthCodeFunctions can also be used to initiate flows, get tokens, or sign requests.

Also includes Refresh token flow, and token management and logout flow.

Install

npm install --save react-oauth2-authcode-provider

Peer Dependencies;

• React v16 +
• Axios v0.19 +

Usage

Minimum required;

import React, { Component } from 'react'

import { AuthCodeProvider } from 'react-oauth2-authcode-provider'
import 'react-oauth2-authcode-provider/dist/index.css'

class Example extends Component {
  render() {
    return 
      <AuthCodeProvider 
        authenticationProps={{
          authUrl: 'https://yourauthserver.com/authorize',
          callBackPath: '/callbackpath',
          tokenUrl: 'https://yourauthserver.com/token',
          clientId: 'your_client_id',
          clientSecret: 'your_client_secret',
          scope: 'somescope offline_access'
        }}
      >
        <div>Your app will go here</div>
      </AuthCodeProvider>
  }
}

See the Examples for an application of this component. This showcases a few different use cases all in one single page application, and you can see this in action whilst hooked up to a test Auth0 server.

Build the Examples with npm install and then npm start to start the development server at http://localhost:3000.

Or view the online example at https://darylbuckle.github.io/react-oauth2-authcode-provider.

A simple example that always requires authentication can also be found at https://github.com/darylbuckle/react-oauth2-authcode-provider-test.

cookiePath	string	'/'	false	Determines the Path for cookies. If hosting in a subdirectory you should set this to the subdirectory path (/subdriectory).
onGetAuthCode	func		false	A call back function that is called before being redirecting to the authorization endpoint.
onReceiveAuthCode	func		false	A call back function that is called when redirected back to the application with the Code parameter populated.
onTokenObtained	func		false	A call back function that is called after retrieving an access token.
onTokenObtainedError	func		false	A call back function that is called if there is an error retrieving an access token.
onTokenRefreshed	func		false	A call back function that is called after retrieving an access token from a refresh token in the background.
onTokenRefreshedError	func		false	A call back function that is called if there is an error retrieving access token from a refresh token in the background.
enableDebugLog	bool	false	false	Set to true to allow additional logging to the console.
signInText	string	'Signing you in'	false	The label 'Signing you in'
