TypeScript SDK

Link to this section

Kinde’s TypeScript SDK allows developers to integrate Kinde Authentication into their JavaScript or TypeScript projects. This SDK implements the following OAuth2.0 flows. Learn more here

  • Authorization Code - Intended for confidential clients, e.g. web-servers
  • Authorization Code with PKCE extension - For public clients, e.g. single page web application and or mobile applications
  • Client Credentials flow - Intended for confidential clients, where machine to machine communication is required.

Node version 16 or newer

Register for Kinde

Link to this section

If you haven’t already got a Kinde account, register for free here (no credit card required). Registering gives you a Kinde domain, which you need to get started, e.g. <your_subdomain>.kinde.com.

Install the SDK using npm or yarn

npm install @kinde-oss/kinde-typescript-sdk
// or
yarn add @kinde-oss/kinde-typescript-sdk

Configure Kinde

Link to this section

Set callback URLs

Link to this section

Kinde will redirect your user to authenticate. They’ll be redirected back to your JavaScript app after signing in or signing up.

To authenticate your app, you need to specify which URL Kinde should redirect your user.

  1. In Kinde, go to Settings > Applications and then navigate to Front-end app or Back-end app which ever applies - or add a new application.

  2. Add your callback URLs in the relevant fields. For example:

    • Allowed callback URLs (also known as redirect URIs): https://<your_app_domain>/callback e.g: http://localhost:3000/callback

    • Allowed logout redirect URLs:

      https://<your_app_domain> e.g:http://localhost:3000

  3. Select Save.

Add environments

Link to this section

Kinde comes with a production environment, but you can set up other environments if you want to. Each environment has a unique subdomain so be sure to use the correct one in the Configure your app section which follows.

Integrate with your app

Link to this section

The @kinde-oss/kinde-typescript-sdk package is intended to work on both Browser and NodeJS environments, consequently for both environments the SDK provides different clients, we provide examples below to demonstrate this.

First step is to configure and create a client. The following settings are needed depend on which authentication flow you are using.

You can find these values on your Settings > Applications > [Your app] > View details page.

  • authDomain - your Kinde domain
  • clientId - your Kinde client ID
  • clientSecret - your Kinde client secret
  • redirectURL - your callback url to redirect to after authentication. Make sure this URL is under your Allowed callback URLs.
  • logoutRedirectURL - where you want users to be redirected to after logging out. Make sure this URL is under your Allowed logout redirect URLs.
import {createKindeServerClient, GrantType} from "@kinde-oss/kinde-typescript-sdk";

// Client for authorization code flow
const kindeClient = createKindeServerClient(GrantType.AUTHORIZATION_CODE, {
    authDomain: "https://<your_kinde_subdomain>.kinde.com",
    clientId: "<your_kinde_client_id>",
    clientSecret: "<your_kinde_client_secret>",
    redirectURL: "http://localhost:3000/callback",
    logoutRedirectURL: "http://localhost:3000"
});

// Client for client credentials flow
const kindeApiClient = createKindeServerClient(GrantType.CLIENT_CREDENTIALS, {
    authDomain: "https://<your_kinde_subdomain>.kinde.com",
    clientId: "<your_kinde_client_id>",
    clientSecret: "<your_kinde_client_secret>",
    logoutRedirectURL: "http://localhost:3000"
});
import {createKindeBrowserClient} from "@kinde-oss/kinde-typescript-sdk";

const kindeClient = createKindeBrowserClient({
    authDomain: "https://<your_kinde_subdomain>.kinde.com",
    clientId: "<your_kinde_client_id>",
    logoutRedirectURL: "http://localhost:3000",
    redirectURL: "http://localhost:3000"
});

Log in and register

Link to this section

To incorporate the login and register features, you’ll need to redirect to Kinde for authentication. One way to do this is to create routes for /login and /register.

const app = express();

app.get("/login", async (req, res) => {
    const loginUrl = await kindeClient.login(sessionManager);
    return res.redirect(loginUrl.toString());
});

app.get("/register", async (req, res) => {
    const registerUrl = await kindeClient.register(sessionManager);
    return res.redirect(registerUrl.toString());
});

app.listen(3000);

With that in place you can simply add links in your HTML as follows:

<a href="/login">Sign in</a> <a href="/register">Sign up</a>

In the above example there is a sessionManager which has not been defined. In order to track the authenticated session between requests a session store is required. Any key-value store can be used for this, you just need to implement the SessionManager interface to provide it to the SDK.

An example session manager storing in memory could be implemented as:

let store: Record<string, unknown> = {};

const sessionManager: SessionManager = {
    async getSessionItem(key: string) {
        return store[key];
    },
    async setSessionItem(key: string, value: unknown) {
        store[key] = value;
    },
    async removeSessionItem(key: string) {
        delete store[key];
    },
    async destroySession() {
        store = {};
    }
};

This would work for a single user for local development purposes, but would need to be expanded for a production environment.

The appropriate session store for your application will depend on your application architecture, for example encrypted cookies in a stateless server environment or a shared cache/database for a load balanced cluster of servers.

Commonly, the session manager will be a wrapper around an existing session management library - often provided by a web framework, or a third party library.

Kinde provides methods for easily implementing a login / register flow.

As an example you can add buttons as follows:

<button onclick="handleLogin()">Sign in</button> <button onclick="handleRegister()">Sign up</button>

Next, define new functions that correspond to each button in your JavaScript or TypeScript file.

async function handleLogin() {
    const url = await kindeClient.login();
    // Redirect
    window.location.href = url.toString();
}

async function handleRegister() {
    const url = await kindeClient.register();
    // Redirect
    window.location.href = url.toString();
}

Manage redirects

Link to this section

You will also need to route /callback. When the user is redirected back to your site from Kinde, it will trigger a call to the callback URL defined in the redirectURL client option.

app.get("/callback", async (req, res) => {
    const url = new URL(`${req.protocol}://${req.get("host")}${req.url}`);
    await kindeClient.handleRedirectToApp(sessionManager, url);
    return res.redirect("/");
});

To handle this, you will have to invoke the handleRedirectToApp function.

async function handleRedirect() {
    try {
        await kindeClient.handleRedirectToApp(new URL(window.location.toString()));
        // Redirect to Home page, etc...
    } catch (error) {
        console.error("ERROR handleRedirect", error);
    }
}

The Kinde SDK comes with a logout method.

app.get("/logout", async (req, res) => {
    const logoutUrl = await kindeClient.logout(sessionManager);
    return res.redirect(logoutUrl.toString());
});
<a href="/logout">Log out</a>
async function handleLogout() {
    const url = await kindeClient.logout();
    // Redirect
    window.location.href = url.toString();
}
<button onclick="handleLogout()">Log out</button>

Check if user is authenticated

Link to this section

We’ve provided a helper to get a boolean value to check if a user is signed in by verifying that the access token is still valid. The isAuthenticated function is only available for authentication code and PKCE flows.

const isAuthenticated = await kindeClient.isAuthenticated(sessionManager); // Boolean: true or false
if (isAuthenticated) {
    // Need to implement, e.g: call an api, etc...
} else {
    // Need to implement, e.g: redirect user to sign in, etc..
}
const isAuthenticated = await kindeClient.isAuthenticated(); // Boolean: true or false

if (isAuthenticated) {
    // Need to implement, e.g: call an api, etc...
} else {
    // Need to implement, e.g: redirect user to sign in, etc..
}

View user profile

Link to this section

You need to have already authenticated before you call the API, otherwise an error will occur.

To access the user information, use the getUserProfile helper function:

const profile = await kindeClient.getUserProfile(sessionManager);
// returns
{
  "given_name":"Dave",
	"id":"kp_12345678910",
	"family_name":"Smith",
	"email":"dave@smith.com",
	"picture": "https://link_to_avatar_url.kinde.com"
}
const profile = await kindeClient.getUserProfile();
// returns
{
  "given_name":"Dave",
	"id":"kp_12345678910",
	"family_name":"Smith",
	"email":"dave@smith.com",
	"picture": "https://link_to_avatar_url.kinde.com"
}

View users in Kinde

Link to this section

Go to the Users page in Kinde to see your newly registered user.

An audience is the intended recipient of an access token - for example the API for your application. The audience argument can be passed to the Kinde client to request an audience be added to the provided token.

const clientOptions = {
	...,
  audience: 'api.yourapp.com',
};

const kindeClient = createKindeServerClient(
  GrantType.AUTHORIZATION_CODE, clientOptions
);
const clientOptions = {
	...,
  audience: 'api.yourapp.com',
};

const kindeClient = createKindeBrowserClient(
  clientOptions
)

For details on how to connect, see Register an API

Overriding scope

Link to this section

By default the KindeSDK requests the following scopes:

  • profile
  • email
  • offline
  • openid

You can override this by passing scopes into the KindeSDK

const clientOptions = {
  ...,
  scope: 'openid profile email offline',
};

const kindeClient = createKindeServerClient(
  GrantType.AUTHORIZATION_CODE, clientOptions
);
const clientOptions = {
  ...,
  scope: 'openid profile email offline',
};

const kindeClient = createKindeBrowserClient(
  clientOptions
)

Create an organization

Link to this section

To have a new organization created within your application during registration, you can create a route as follows:

NodeJS

app.get("/createOrg", async (req, res) => {
    const org_name = req.query.org_name?.toString();
    const createUrl = await kindeClient.createOrg(sessionManager, {org_name});
    return res.redirect(createUrl.toString());
});

Browser

const handleCreateOrg = async (org_name: string) => {
    const url = await kindeClient.createOrg({org_name});
    window.location.href = url.toString();
};

You can also pass org_name as part of the query string as per the following HTML:

NodeJS

<a href="/createOrg?org_name=<your_org_name>">Create Org</a>

Browser

<button onclick="handleCreateOrg('your_org_name')">Create Org</button>

Log in and register to organizations

Link to this section

The Kinde client provides methods for you to easily log in and register users into existing organizations.

NodeJS

Update the routes to accept an org_code parameter and pass it to the SDK:

const loginUrl = await kindeClient.login(sessionManager, {org_code: "org_1234"});

const registerUrl = await kindeClient.register(sessionManager, {org_code: "org_1234"});

Browser

// HTML
<button onclick="handleLoginIntoOrgnization('org_1234')">Sign into</button>
<button onclick="handleRegisterIntoOrgnization('org_1234')">Sign up</button>

// JS/TS file
async function handleLoginIntoOrgnization(org_code){
	await kindeClient.login({org_code});
}

async function handleRegisterIntoOrgnization(org_code){
	await kindeClient.register({org_code});
}

Following authentication, Kinde provides a json web token (jwt) to your application. Along with the standard information we also include the org_code and the permissions for that organization (this is important as a user can belong to multiple organizations and have different permissions for each).

Example of a returned token:

{
    "aud": [],
    "exp": 1658475930,
    "iat": 1658472329,
    "iss": "https://your_subdomain.kinde.com",
    "jti": "123457890",
    "org_code": "org_1234",
    "permissions": ["read:todos", "create:todos"],
    "scp": ["openid", "profile", "email", "offline"],
    "sub": "kp:123457890"
}

The id_token will also contain an array of organizations that a user belongs to - this is useful if you wanted to build out an organization switcher for example.

[
		...
		"org_codes": ["org_1234", "org_4567"]
		...
];

There are two helper functions you can use to extract information:

NodeJS

const org = await kindeClient.getOrganization(sessionManager); // { orgCode: 'org_1234' }

const orgs = await kindeClient.getUserOrganizations(sessionManager); // { orgCodes: ['org_1234', 'org_abcd'] }

Browser

const org = await kindeClient.getOrganization(); // { orgCode: 'org_1234' }

const orgs = await kindeClient.getUserOrganizations(); // { orgCodes: ['org_1234', 'org_abcd'] }

User permissions

Link to this section

Once a user has been verified, your product/application will return the JWT token with an array of permissions for that user. You will need to configure your product/application to read permissions and unlock the respective functions.

Set permissions in your Kinde account. Here’s an example set of permissions.

const permissions = [
    "create:todos",
    "update:todos",
    "read:todos",
    "delete:todos",
    "create:tasks",
    "update:tasks",
    "read:tasks",
    "delete:tasks"
];

We provide helper functions to more easily access the permissions claim:

NodeJS

const permission = await kindeClient.getPermission(sessionManager, "create:todos"); // { orgCode: 'org_1234', isGranted: true }

const permissions = await kindeClient.getPermissions(sessionManager); // { orgCode: 'org_1234', permissions: ['create:todos', 'update:todos', 'read:todos'] }

Browser

const permission = await kindeClient.getPermission("create:todos"); // { orgCode: 'org_1234', isGranted: true }

const permissions = await kindeClient.getPermissions(); // { orgCode: 'org_1234', permissions: ['create:todos', 'update:todos', 'read:todos'] }

A practical example in code might look something like:

NodeJS

const permission = await kindeClient.getPermission(sessionManager, "create:todos");
if (permission.isGranted) {
    ...
}

Browser

const permission = await kindeClient.getPermission("create:todos");
if (permission.isGranted) {
    ...
}

Getting claims

Link to this section

We have provided a helper to grab any claim from your id or access tokens. The helper defaults to access tokens:

client.getClaim(sessionManager, "aud"); // { name: "aud", value: ["local-testing@kinde.com"] }

client.getClaimValue(sessionManager, "aud"); // ["local-testing@kinde.com"]

client.getClaim(sessionManager, "email", "id_token"); // { name: "email", value: "first.last@test.com" }

client.getClaimValue(sessionManager, "email", "id_token"); // "first.last@test.com"
client.getClaim("aud"); // { name: "aud", value: ["local-testing@kinde.com"] }

client.getClaimValue("aud"); // ["local-testing@kinde.com"]

client.getClaim("email", "id_token"); // { name: "email", value: "first.last@test.com" }

client.getClaimValue("email", "id_token"); // "first.last@test.com"

We have provided a helper to return any features flag from the access token:

client.getFeatureFlag(sessionManager, 'theme')
// returns
{
	"is_default": false
  "value": "pink",
  "code": "theme",
  "type": "string",
}

client.getFeatureFlag(sessionManager, 'no-feature-flag')
// returns
// Error: "Flag no-feature-flag was not found, and no default value has been provided"

client.getFeatureFlag(sessionManager, 'no-feature-flag', 'default-value')
// returns
{
	"is_default": true
	"code": "no-feature-flag",
	"value": "default-value",
}

client.getFeatureFlag(sessionManager, 'theme', 'default-theme', 'b')
// returns
// Error: "Flag theme is of type string, expected type is boolean
client.getFeatureFlag('theme')
// returns
{
	"is_default": false
  "value": "pink",
  "code": "theme",
  "type": "string",
}

client.getFeatureFlag('no-feature-flag')
// returns
// Error: "Flag no-feature-flag was not found, and no default value has been provided"


client.getFeatureFlag('no-feature-flag', 'default-value')
// returns
{
	"is_default": true
	"code": "no-feature-flag",
	"value": "default-value",
}

client.getFeatureFlag('theme', 'default-theme', 'b')
// returns
// Error: "Flag theme is of type string, expected type is boolean

We also require wrapper functions by type which should leverage getFlag above.

After the user has successfully logged in, you will have a JSON Web Token (JWT) and a refresh token securely stored. You can retrieve an access token by utilizing the getToken method.

// NodeJS
const accessToken = await kindeClient.getToken(sessionManager);
const accessToken = await kindeClient.getToken();

Kinde Management API

Link to this section

The sections below relate to how to call the Kinde Management API. You need to add a machine to machine application and get an access token to connect:

import {
    Configuration,
    GrantType,
    UsersApi,
    createKindeServerClient
} from "@kinde-oss/kinde-typescript-sdk";

const kindeApiClient = createKindeServerClient(GrantType.CLIENT_CREDENTIALS, {
    authDomain: "https://<your_kinde_subdomain>.kinde.com",
    clientId: "<your_kinde_client_id>",
    clientSecret: "<your_kinde_client_secret>",
    logoutRedirectURL: "http://localhost:3000",
    audience: "https://<your_kinde_subdomain>.kinde.com/api",
    scope: ""
});

const token = await kindeApiClient.getToken(sessionManager);

const config = new Configuration({
    basePath: "https://<your_kinde_subdomain>.kinde.com",
    accessToken: token,
    headers: {Accept: "application/json"}
});
