Introduction

Asgardeo Auth JavaScript SDK provides the core methods that are needed to implement OIDC authentication in JavaScript/TypeScript-based apps. This SDK can be used to build SDKs for Single-Page Applications, React Native, Node.JS and various other frameworks that use JavaScript.

Prerequisite

Create an organization in Asgardeo if you don't already have one. The organization name you choose will be referred to as <org_name> throughout this tutorial.

Install

Install the library from the npm registry.

npm install @asgardeo/auth-js

Getting Started

Using an Embedded Script

// The SDK provides a client that can be used to carry out the authentication.
import { AsgardeoAuthClient } from "@asgardeo/auth-js";

// Create a config object containing the necessary configurations.
const config = {
    signInRedirectURL: "http://localhost:3000/sign-in",
    signOutRedirectURL: "http://localhost:3000/dashboard",
    clientID: "client ID",
    baseUrl: "https://api.asgardeo.io/t/<org_name>"
};

// Create a Store class to store the authentication data. The following implementation uses the session storage.
class SessionStore {
    // Saves the data to the store.
    async setData(key, value) {
        sessionStorage.setItem(key, value);
    }

    // Gets the data from the store.
    async getData(key) {
        return sessionStorage.getItem(key);
    }

    // Removes the date from the store.
    async removeData(key) {
        sessionStorage.removeItem(key);
    }
}

class CryptoUtils {
    // Encodes the input data into base64 URL encoded string.
    public base64URLEncode(value) {
        return base64url.encode(value).replace(/\+/g, "-").replace(/\//g, "_").replace(/=/g, "");
    }

    // Decodes the base64 URL encoded string into the original data.
    public base64URLDecode(value) {
        return base64url.decode(value).toString();
    }

    // Hashes the input data using SHA256.
    public hashSha256(data) {
        return Buffer.from(sha256(new TextEncoder().encode(data)));
    }

    // Generates a random bytes of the specified length.
    public generateRandomBytes(length) {
        return randombytes(length);
    }

    // Verifies the JWT signature.
    public verifyJwt(
        idToken,
        jwk,
        algorithms,
        clientID,
        issuer,
        subject,
        clockTolerance
    ) {
        // Parses the key object into a format that would be accepted by verifyJwt()
        const key = parseJwk(jwk);

        return jwtVerify(idToken, jwk, {
            algorithms: algorithms,
            audience: clientID,
            clockTolerance: clockTolerance,
            issuer: issuer,
            subject: subject
        }).then(() => {
            return Promise.resolve(true);
        });
    }
}

// Instantiate the SessionStore class
const store = new SessionStore();

// Instantiate the CryptoUtils class
const cryptoUtils = new CryptoUtils();

// Instantiate the AsgardeoAuthClient and pass the store object as an argument into the constructor.
const auth = new AsgardeoAuthClient();

// Initialize the instance with the config object.
auth.initialize(config, store, cryptoUtils);

// To get the authorization URL, simply call this method.
auth.getAuthorizationURL()
    .then((url) => {
        // Redirect the user to the authentication URL. If this is used in a browser,
        // you may want to do something like this:
        window.location.href = url;
    })
    .catch((error) => {
        console.error(error);
    });

// Once you obtain the authentication code and the session state from the server, you can use this method
// to get the access token.
auth.requestAccessToken("code", "session-state", "state")
    .then((response) => {
        // Obtain the token and other related from the response;
        console.log(response);
    })
    .catch((error) => {
        console.error(error);
    });

APIs

The SDK provides a client class called AsgardeoAuthClient that provides you with the necessary methods to implement authentication. You can instantiate the class and use the object to access the provided methods.

constructor

new AsgardeoAuthClient();

Description

This creates an instance of the AsgardeoAuthClient class and returns it.

Example

const auth = new AsgardeoAuthClient();

initialize

initialize(config: AuthClientConfig<T>, store: Store, cryptoUtils: CryptoUtils): Promise<void>;

Arguments

1. config: AuthClientConfig<T>

   This contains the configuration information needed to implement authentication such as the client ID, server origin etc. Additional configuration information that is needed to be stored can be passed by extending the type of this argument using the generic type parameter. For example, if you want the config to have an attribute called foo, you can create an interface called Bar in TypeScript and then pass that interface as the generic type to AuthClientConfig interface. To learn more about what attributes can be passed into this object, refer to the AuthClientConfig<T> section.

   interface Bar {
       foo: string
   }
   
   const auth = new AsgardeoAuthClient(config: AuthClientConfig<Bar>, store: Store, cryptoUtils: CryptoUtils);

2. store: Store

   This is the object of interface Store that is used by the SDK to store all the necessary data used ranging from the configuration data to the access token. You can implement the Store to create a class with your own implementation logic and pass an instance of the class as the second argument. This way, you will be able to get the data stored in your preferred place. To know more about implementing the Store interface, refer to the Data Storage section.

3. cryptoUtils: CryptoUtils

   This is the object of the interface CryptoUtils that is used by the SDK to perform cryptographic functions. Since the crypto implementation varies from environment to environment, this object is used to inject environment-specific crypto implementation. So, developers are expected to implement this interface and pass an object of this interface as an argument to the constructor. To know more about implementing this interface, refer to the CryptoUtils section.

Description

This method initializes the instance with the config data.

Example

const config = {
    signInRedirectURL: "http://localhost:3000/sign-in",
    signOutRedirectURL: "http://localhost:3000/dashboard",
    clientID: "client ID",
    baseUrl: "https://api.asgardeo.io/t/<org_name>"
};
const _store: Store = initiateStore(config.storage);
const _cryptoUtils: SPACryptoUtils = new SPACryptoUtils();

const auth = new AsgardeoAuthClient<MainThreadClientConfig>();

await auth.initialize(config, _store, _cryptoUtils);

getDataLayer

getDataLayer(): DataLayer<T>

Returns

Arguments

1. pkce: string

The PKCE code generated by the getAuthorizationURL method. 2. state: string The state parameter that was passed in the authorization request. 3. userID: string (optional)

If you want to use the SDK to manage multiple user sessions, you can pass a unique ID here. This can be useful when this SDK is used in backend applications.

Description

This method sets the PKCE code to the store. The PKCE code is usually stored in the store by the SDK. But there could be instances when the store could be cleared such as when the data is stored in the memory and the user is redirected to the authorization endpoint in a Single Page Application. When the user is redirected back to the app, the authorization code, session state, and the PKCE code will have to be sent to the server to obtain the access token. However, since, during redirection, everything in the memory is cleared, the PKCE code cannot be obtained. In such instances, the getPKCECode method can be used to get the PKCE code before redirection and store it in a place from where it can be retrieved after redirection, and then this method can be used to save the PKCE code to the store so that the requestAccessToken method can run successfully.

Example

auth.setPKCECode(pkce, state);

isSignOutSuccessful

static isSignOutSuccessful(signOutRedirectURL: string): boolean

This is a static method.

Arguments

1. signOutRedirectURL: string

   The URL to which the user is redirected to after signing out from the server.

Returns

isSignedOut: boolean

A boolean value indicating if the user has been signed out or not.

Description

This method returns if the user has been successfully signed out or not. When a user signs out from the server, the user is redirected to the URL specified by the signOutRedirectURL in the config object passed into the constructor of the AsgardeoAuthClient. The server appends path parameters indicating if the sign-out is successful. This method reads the URL and returns if the sign-out is successful or not. So, make sure you pass as the argument the URL to which the user has been redirected to after signing out from the server.

Example

const isSignedOut = auth.isSignOutSuccessful(window.location.href);

didSignOutFail

static didSignOutFail(signOutRedirectURL: string): boolean

This is a static method.

Arguments

1. signOutRedirectURL: string

   The URL to which the user is redirected to after signing out from the server.

Returns

didSignOutFail: boolean

A boolean value indicating if sign-out failed or not.

Description

This method returns if sign-out failed or not. When a user signs out from the server, the user is redirected to the URL specified by the signOutRedirectURL in the config object passed into the constructor of the AsgardeoAuthClient. The server appends path parameters indicating if the sign-out is successful. This method reads the URL and returns if the sign-out failed or not. So, make sure you pass as the argument the URL to which the user has been redirected to after signing out from the server.

Example

const didSignOutFail = auth.didSignOutFail(window.location.href);

updateConfig

updateConfig(config: Partial<AuthClientConfig<T>>): Promise<void>

Arguments

1. config: AuthClientConfig<T>

The config object containing the attributes that can be used to configure the SDK. To learn more about the available attributes, refer to the AuthClientConfig>T> model.

Description

This method can be used to update the configurations passed into the constructor of the AsgardeoAuthClient. Please note that every attribute in the config object passed as the argument here is optional. Use this method if you want to update certain attributes after instantiating the class.

Example

// This should be within an async function.
await auth.updateConfig({
    signOutRedirectURL: "http://localhost:3000/sign-out"
});

Data Storage

Since the SDK was developed with the view of being able to support various platforms such as mobile apps, browsers and node.js servers, the SDK allows developers to use their preferred mode of storage. To that end, the SDK allows you to pass a store object when instantiating the AsgardeoAuthClient. This store object contains methods that can be used to store, retrieve and delete data. The SDK provides a Store interface that you can implement to create your own Store class. You can refer to the Store section to learn more about the Store interface.

There are three methods that are to be implemented by the developer. They are

1. setData
2. getData
3. removeData

The setData method is used to store data. The getData method is used to retrieve data. The removeData method is used to delete data. The SDK converts the data to be stored into a JSON string internally and then calls the setData method to store the data. The data is represented as a key-value pairs in the SDK. The SDK uses four keys internally and you can learn about them by referring to the Data Layer section. So, every JSON stringified data value is supposed to be stored against the passed key in the data store. A sample implementation of the Store class using the browser session storage is given here.

class SessionStore implements Store {
    public setData(key: string, value: string): void {
        sessionStorage.setItem(key, value);
    }

    public getData(key: string): string {
        return sessionStorage.getItem(key);
    }

    public removeData(key: string): void {
        sessionStorage.removeItem(key);
    }
}

Data Layer

The data layer is implemented within the SDK encapsulating the Store object passed into the constructor. The data layer acts as the interface between the SDK and the store object and provides a more developer-friendly interface to store, retrieve and delete data. Four keys are used to store four different sets of data. The keys are:

1. Session Data Stores session data such as the access token, id token, refresh token, session state etc. Refer to SessionData to get the full list of data stored.
2. OIDC Provider Meta Data Stores regarding OIDC Meta Data obtained from the .well-known endpoint. Refer to OIDCProviderMetaData for the full list of data stored.
3. Config Data Stores the config data passed to the constructor. Refer to AuthClientConfig<T> for the full list of data stored.
4. Temporary Data Stores data that is temporary. In most cases, you wouldn't need this.

All these four keys get methods to set, get and remove data as whole. In addition to this, all these keys get methods to set, get, and remove specific data referred to by their respective keys. The following table describes the methods provided by the data layer. | Method | Arguments | Returns | Description | |-------------------------------------|------------------------------------------------------------------------------------------------|--------------------------------------------------------------|---------------------------------------------------------------------------------| | setSessionData | sessionData: SessionData | Promise<void> | Saves session data in bulk. | | setOIDCProviderMetaData | oidcProviderMetaData: OIDCProviderMetaData | Promise<void> | Saves OIDC Provider Meta data in bulk. | | setConfigData | config: AuthClientConfig<T> | Promise<void> | Saves config data in bulk. | | setTemporaryData | data: TemporaryData | Promise<void> | Saves temporary data in bulk. | | getSessionData | | Promise<SessionData> | Retrieves session data in bulk. | | getOIDCProviderMetaData | | Promise<OIDCProviderMetaData> | Retrieves OIDC Provider Meta data in bulk. | | getConfigData | | Promise<AuthClientConfig<T>> | Retrieves config data in bulk. | | getTemporaryData | | Promise<{ key: string: StoreValue}> | Retrieves temporary data in bulk. | | removeSessionData | | Promise<void> | Removes session data in bulk. | | removeOIDCProviderMetaData | | Promise<void> | Removes OIDC Provider Meta data in bulk. | | removeConfigData | | Promise<void> | Removes config data in bulk. | | removeTemporaryData | | Promise<void> | Removes temporary data in bulk. | | setSessionDataParameter | key: keyof SessionData, value: StoreValue | Promise<void> | Saves the passed data against the specified key in the session data. | | setOIDCProviderMetaDataParameter | key: keyof OIDCProviderMetaData, value: StoreValue | Promise<void> | Saves the passed data against the specified key in the OIDC Provider Meta data. | | setConfigDataParameter | key: keyof AuthClientConfig<T>, value: StoreValue | Promise<void> | Saves the passed data against the specified key in the config data. | | setTemporaryDataParameter | key: string, value: StoreValue | Promise<void> | Saves the passed data against the specified key in the temporary data. | | getSessionDataParameter | key: keyof SessionData | Promise<StoreValue> | Retrieves the data for the specified key from the session data. | | getOIDCProviderMetaDataParameter | key: keyof OIDCProviderMetaData | Promise<StoreValue> | Retrieves the data for the specified key from the OIDC Provider Meta data. | | getConfigDataParameter | key: keyof AuthClientConfig<T> | Promise<StoreValue> | Retrieves the data for the specified key from the config data. | | getTemporaryDataParameter | key: string | Promise<StoreValue> | Retrieves the data for the specified key from the temporary data. | | removeSessionDataParameter | key: keyof SessionData | Promise<void> | Removes the data with the specified key from the session data. | | removeOIDCProviderMetaDataParameter | key: keyof OIDCProviderMetaData | Promise<void> | Removes the data with the specified key from the OIDC Provider Meta data. | | removeConfigDataParameter | key: keyof AuthClientConfig<T> | Promise<void> | Removes the data with the specified key from the config data. | | removeTemporaryDataParameter | key: string | Promise<void> | Removes the data with the specified key from the temporary data. |

CryptoUtils

The CryptoUtils interface defines the methods required to perform cryptographic operations such as producing a PKCE code and verifying ID tokens. The following table describes the methods provided by the CryptoUtils interface. | Method | Arguments | Returns | Description | |-----------------------|------------------------------------|--------------------|------------------------------------------------------------------| | base64urlEncode | input: T | string | Encodes the passed input string to a base64url encoded string. | | base64urlDecode | input: string | string | Decodes the passed input string from a base64url encoded string. | | hashSha256 | input: string | T | Hashes the passed input string using SHA-256. | | generateRandomBytes | length: number | T | Generates random bytes of the specified length. | | verifyJwt | jwt: string, jwk: JWKInterface | Promise<boolean> | Verifies the passed JWT using the passed JWK. |

NOTE: The return type of the hashSha256 and generateRandomBytes method should be the same as the type of the argument of the base64urlEncode method.

These methods should be implemented in a class and the instance of the class should be passed as an argument into the constructor of AsgardeoAuthClient.

Models

AuthClientConfig\

This model has the following attributes. |Attribute| Required/Optional| Type | Default Value| Description| |--|--|--|--|--| |signInRedirectURL |Required|string|""|The URL to redirect to after the user authorizes the client app. eg: https//localhost:3000/sign-in| |signOutRedirectURL |Optional|string| The signInRedirectURL URL will be used if this value is not provided. |The URL to redirect to after the user |signs out. eg: http://localhost:3000/dashboard| |clientHost|Optional| string|The origin of the client app obtained using window.origin|The hostname of the client app. eg: https://localhost:3000| |clientID|Required| string|""|The client ID of the OIDC application hosted in the Asgardeo.| |clientSecret|Optional| string|""|The client secret of the OIDC application| |enablePKCE|Optional| boolean|true| Specifies if a PKCE should be sent with the request for the authorization code.| |prompt|Optional| string|""|Specifies the prompt type of an OIDC request| |responseMode|Optional| ResponseMode|"query"|Specifies the response mode. The value can either be query or form_post| |scope|Optional| string[]|["openid"]|Specifies the requested scopes.| |baseUrl|Required (If wellKnownEndpoint or endpoints is not provided)| string|""|The origin of the Identity Provider. eg: https://api.asgardeo.io/t/<org_name>.| |endpoints|Optional (Required to provide all endpoints, if wellKnownEndpoint or baseUrl is not provided)| OIDCEndpoints|OIDC Endpoints Default Values|The OIDC endpoint URLs. The SDK will try to obtain the endpoint URLS |using the .well-known endpoint. If this fails, the SDK will use these endpoint URLs. If this attribute is not set, then the default endpoint URLs will be |used. |wellKnownEndpoint|Optional (Required if baseUrl or endpoints is not provided)| string|"/oauth2/token/.well-known/openid-configuration"| The URL of the .well-known endpoint.| |validateIDToken|Optional| boolean|true|Allows you to enable/disable JWT ID token validation after obtaining the ID token.| |validateIDTokenIssuer(optional) | boolean | true | Allows you to enable/disable JWT ID token issuer validation after obtaining the ID token (This config is applicable only when JWT ID token validation is enabled). | |clockTolerance|Optional| number|60|Allows you to configure the leeway when validating the id_token.| |sendCookiesInRequests|Optional| boolean|true|Specifies if cookies should be sent in the requests.| |sendIdTokenInLogoutRequest|Optional| boolean|false|Specifies if id_token_hint parameter should be sent in the logout request instead of the default client_id parameter.|

The AuthClientConfig<T> can be extended by passing an interface as the generic type. For example, if you want to add an attribute called foo to the config object, you can create an interface called Bar and pass that as the generic type into the AuthClientConfig<T> interface.

interface Bar {
    foo: string
}

const config: AuthClientConfig<Bar> ={
    ...
}

CustomGrantConfig

Custom Grant Template Tags

Session information can be attached to the body of a custom-grant request using template tags. This is useful when the session information is not exposed outside the SDK but you want such information to be used in custom-grant requests. The following table lists the available template tags. | Tag | Data | |--------------------|--------------------| | "{{token}}" | The access token. | | {{username}}" | The username. | | "{{scope}}" | The scope. | | {{clientID}}" | The client ID. | | "{{clientSecret}}" | The client secret. |
