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.
``bash`
npm install --save react-oauth2-authcode-provider
Peer Dependencies;
* React v16 +
* Axios v0.19 +

`tsx
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
authUrl: 'https://yourauthserver.com/authorize',
callBackPath: '/callbackpath',
tokenUrl: 'https://yourauthserver.com/token',
clientId: 'your_client_id',

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
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.

| history | ReactRouterHistory | | false | React router history object. If set this will be used for post authentication redirects and removing the code parameter. If not provided the page will be reloaded to remove the code parameter and redirect. |
| storagePrefix | string | '' | false | Used if you are authenticating with multiple oauth2 servers, you can store multiple access tokens. The second/third/etc instance should have a unique prefixes. |
| 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' |
| signInText | string | 'Signing you out' | false | The label 'Signing you out' |
