openid-client

OAuth 2 / OpenID Connect Client API for JavaScript Runtimes

openid-client simplifies integration with authorization servers by providing easy-to-use APIs for the most common authentication and authorization flows, including OAuth 2 and OpenID Connect. It is designed for JavaScript runtimes like Node.js, Browsers, Deno, Cloudflare Workers, and more.

Features

The following features are currently in scope and implemented in this software:

Authorization Server Metadata discovery
Authorization Code Flow (profiled under OpenID Connect 1.0, OAuth 2.0, OAuth 2.1, FAPI 1.0 Advanced, and FAPI 2.0)
Refresh Token, Device Authorization, Client-Initiated Backchannel Authentication (CIBA), and Client Credentials Grants
Demonstrating Proof-of-Possession at the Application Layer (DPoP)
Token Introspection and Revocation
Pushed Authorization Requests (PAR)
UserInfo and Protected Resource Requests
Authorization Server Issuer Identification
JWT Secured Introspection, Response Mode (JARM), Authorization Request (JAR), and UserInfo
Dynamic Client Registration (DCR)
Passport Strategy

If you want to quickly add authentication to JavaScript apps, feel free to check out Auth0's JavaScript SDK and free plan. Create an Auth0 account; it's free!

Certification

Filip Skokan has certified that this software conforms to the Basic, FAPI 1.0, and FAPI 2.0 Relying Party Conformance Profiles of the OpenID Connect™ protocol.

Quick start

let server!: URL // Authorization Server's Issuer Identifier
let clientId!: string // Client identifier at the Authorization Server
let clientSecret!: string // Client Secret

let config: client.Configuration = await client.discovery(
  server,
  clientId,
  clientSecret,
)

Authorization Code Flow

Authorization Code flow is for obtaining Access Tokens (and optionally Refresh Tokens) to use with third party APIs.

When you want to have your end-users authorize or authenticate you need to send them to the authorization server's authorization_endpoint. Consult the web framework of your choice on how to redirect but here's how to get the authorization endpoint's URL with parameters already encoded in the query to redirect to.

/**
 * Value used in the authorization request as the redirect_uri parameter, this
 * is typically pre-registered at the Authorization Server.
 */
let redirect_uri!: string
let scope!: string // Scope of the access request
/**
 * PKCE: The following MUST be generated for every redirect to the
 * authorization_endpoint. You must store the code_verifier and state in the
 * end-user session such that it can be recovered as the user gets redirected
 * from the authorization server back to your application.
 */
let code_verifier: string = client.randomPKCECodeVerifier()
let code_challenge: string =
  await client.calculatePKCECodeChallenge(code_verifier)
let state!: string

let parameters: Record<string, string> = {
  redirect_uri,
  scope,
  code_challenge,
  code_challenge_method: 'S256',
}

if (!config.serverMetadata().supportsPKCE()) {
  /**
   * We cannot be sure the server supports PKCE so we're going to use state too.
   * Use of PKCE is backwards compatible even if the AS doesn't support it which
   * is why we're using it regardless. Like PKCE, random state must be generated
   * for every redirect to the authorization_endpoint.
   */
  state = client.randomState()
  parameters.state = state
}

let redirectTo: URL = client.buildAuthorizationUrl(config, parameters)

// now redirect the user to redirectTo.href
console.log('redirecting to', redirectTo.href)

When end-users are redirected back to the redirect_uri your application consumes the callback and passes in PKCE code_verifier to include it in the authorization code grant token exchange.

let getCurrentUrl!: (...args: any) => URL

let tokens: client.TokenEndpointResponse = await client.authorizationCodeGrant(
  config,
  getCurrentUrl(),
  {
    pkceCodeVerifier: code_verifier,
    expectedState: state,
  },
)

console.log('Token Endpoint Response', tokens)

You can then fetch a protected resource response

let protectedResourceResponse: Response = await client.fetchProtectedResource(
  config,
  tokens.access_token,
  new URL('https://rs.example.com/api'),
  'GET',
)

console.log(
  'Protected Resource Response',
  await protectedResourceResponse.json(),
)

Device Authorization Grant (Device Flow)

let scope!: string // Scope of the access request

let response = await client.initiateDeviceAuthorization(config, { scope })

console.log('User Code:', response.user_code)
console.log('Verification URI:', response.verification_uri)
console.log('Verification URI (complete):', response.verification_uri_complete)

You will display the instructions to the end-user and have them directed at verification_uri or verification_uri_complete, afterwards you can start polling for the Device Access Token Response.

let tokens: client.TokenEndpointResponse =
  await client.pollDeviceAuthorizationGrant(config, response)

console.log('Token Endpoint Response', tokens)

This will poll in a regular interval and only resolve with tokens once the end-user authenticates.

Client-Initiated Backchannel Authentication (CIBA)

let scope!: string // Scope of the access request
/**
 * One of login_hint, id_token_hint, or login_hint_token parameters must be
 * provided in CIBA
 */
let login_hint!: string

let response = await client.initiateBackchannelAuthentication(config, {
  scope,
  login_hint,
})

/**
 * OPTIONAL: If your client is configured with Ping Mode you'd invoke the
 * following after getting the CIBA Ping Callback (its implementation is
 * framework specific and therefore out of scope for openid-client)
 */

let tokens: client.TokenEndpointResponse =
  await client.pollBackchannelAuthenticationGrant(config, response)

console.log('Token Endpoint Response', tokens)

This will poll in a regular interval and only resolve with tokens once the end-user authenticates.

Client Credentials Grant

Client Credentials flow is for obtaining Access Tokens to use with third party APIs on behalf of your application, rather than an end-user which was the case in previous examples.

let scope!: string // Scope of the access request
let resource!: string // Resource Indicator of the Resource Server the access token is for

let tokens: client.TokenEndpointResponse = await lib.clientCredentialsGrant(
  config,
  { scope, resource },
)

console.log('Token Endpoint Response', tokens)

Supported Runtimes

The supported JavaScript runtimes include those that support the utilized Web API globals and standard built-in objects. These are (but are not limited to):

Browsers
Bun
Cloudflare Workers
Deno
Electron
Node.js[^nodejs]

Supported Versions

Version	Security Fixes 🔑	Other Bug Fixes 🐞	New Features ⭐	Runtime and Module type
v6.x	Security Policy	✅	✅	Universal[^universal] ESM[^cjs]
v5.x	Security Policy	❌	❌	Node.js CJS + ESM

[^nodejs]: Node.js v20.x as baseline is required

[^universal]: Assumes runtime support of WebCryptoAPI and Fetch API

[^cjs]: CJS style let client = require('openid-client') is possible in Node.js versions where the require(esm) feature is enabled by default (^20.19.0 || ^22.12.0 || >= 23.0.0).
