# @axa-fr/oidc-client
@axa-fr/oidc-client the lightest and securest library to manage authentication with OpenID Connect (OIDC) and OAuth2 protocol. It is compatible with all OIDC providers. @axa-fr/oidc-client is a pure javascript library. It works with any JavaScript framework or library.
We provide a wrapper @axa-fr/react-oidc for React (compatible next.js) and we expect soon to provide one for Vue, Angular and Svelte.
- Try the react demo at https://black-rock-0dc6b0d03.1.azurestaticapps.net/ (most advanced)
- Try the pure javascript demo at https://icy-glacier-004ab4303.2.azurestaticapps.net/
About
@axa-fr/oidc-client is:
- Secure :
- With Demonstrating Proof of Possession (DPoP), your access_token and refresh_token are not usable outside your browser context (big protection)
- With the use of Service Worker, your tokens (refresh_token and/or access_token) are not accessible to the JavaScript client code (if you follow good practices from
FAQsection) - OIDC using client side Code Credential Grant with pkce only
- Lightweight : Unpacked Size on npm is 274 kB
- Simple
- refresh_token and access_token are auto refreshed in background
- with the use of the Service Worker, you do not need to inject the access_token in every fetch, you have only to configure OidcTrustedDomains.js file
- Multiple Authentication :
- You can authenticate many times to the same provider with different scope (for example you can acquire a new 'payment' scope for a payment)
- You can authenticate to multiple different providers inside the same SPA (single page application) website
- Flexible :
- Work with Service Worker (more secure) and without for older browser (less secure).
- You can disable Service Worker if you want (but less secure) and just use SessionStorage or LocalStorage mode.
The service worker catch access_token and refresh_token that will never be accessible to the client.
Getting Started
npm install @axa-fr/oidc-client --save
# To install or update OidcServiceWorker.js file, you can run
node ./node_modules/@axa-fr/oidc-client/bin/copy-service-worker-files.mjs public
# If you have a "public" folder, the 2 files will be created :
# ./public/OidcServiceWorker.js <-- will be updated at each "npm install"
# ./public/OidcTrustedDomains.js <-- won't be updated if already existWARNING : If you use Service Worker mode, the OidcServiceWorker.js file should always be up to date with the version of the library. You may setup a postinstall script in your package.json file to update it at each npm install. For example :
"scripts": {
...
"postinstall": "node ./node_modules/@axa-fr/oidc-client/bin/copy-service-worker-files.mjs public"
},If you need a very secure mode where refresh_token and access_token will be hide behind a service worker that will proxify requests. The only file you should edit is "OidcTrustedDomains.js".
// OidcTrustedDomains.js
// Add bellow trusted domains, access tokens will automatically injected to be send to
// trusted domain can also be a path like https://www.myapi.com/users,
// then all subroute like https://www.myapi.com/useers/1 will be authorized to send access_token to.
// Domains used by OIDC server must be also declared here
const trustedDomains = {
default: {
oidcDomains: ['https://demo.duendesoftware.com'],
accessTokenDomains: ['https://www.myapi.com/users'],
},
};
// Service worker will continue to give access token to the JavaScript client
// Ideal to hide refresh token from client JavaScript, but to retrieve access_token for some
// scenarios which require it. For example, to send it via websocket connection.

accessTokenDomains: ['https://www.myapi.com/users'],
showAccessToken: false,

// setAccessTokenToNavigateRequests: true, // default value is true
};

How It Works
This component is a pure vanilla JS OIDC client library agnostic to any framework. It is a real alternative to existing oidc-client libraries.
