import React from 'react';

import SuperTokens, { SuperTokensWrapper } from "supertokens-auth-react";
import EmailPassword from "supertokens-auth-react/recipe/emailpassword";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
    appInfo: {
        // learn more about this on https://supertokens.com/docs/emailpassword/appinfo
        appName: "<YOUR_APP_NAME>",
        apiDomain: "<YOUR_API_DOMAIN>",
        websiteDomain: "<YOUR_WEBSITE_DOMAIN>",
        apiBasePath: "/auth",
        websiteBasePath: "/auth",
    },
    recipeList: [
        EmailPassword.init(),
        Session.init()
    ]
});


/* Your App */
class App extends React.Component {
    render() {
        return (
            <SuperTokensWrapper>
                {/*Your app components*/}
            </SuperTokensWrapper>
        );
    }
}

Angular

Before we initialize the supertokens-auth-react SDK let's see how we will use it in our Angular app

Architecture

• The supertokens-auth-react SDK is responsible for rendering the login UI, handling authentication flows and session management.
• Using supertokens-auth-react's pre-built UI does not increase application's bundle size. React is only added to authentication-related routes.

Creating the /auth route

• Use the Angular CLI to generate a new route

  ng generate module auth --route auth --module app.module

• In your auth component folder create a react component supertokensAuthComponent.tsx. This component will be used to render appropriate UI when user visits the login page.

  /app/auth/supertokensAuthComponent.tsx

  import * as React from "react";
  import * as SuperTokens from "supertokens-auth-react";
  import { canHandleRoute, getRoutingComponent } from "supertokens-auth-react/ui";
  import { EmailPasswordPreBuiltUI } from "supertokens-auth-react/recipe/emailpassword/prebuiltui";
  
  class SuperTokensReactComponent extends React.Component {
      override render() { 
          if (canHandleRoute([EmailPasswordPreBuiltUI])) {
              return getRoutingComponent([EmailPasswordPreBuiltUI]);
          }
          return "Route not found";
      }
  }
  
  export default SuperTokensReactComponent;

• Load superTokensAuthComponent in the auth angular component

  /app/auth/auth.component.ts

  import { AfterViewInit, Component, OnDestroy } from "@angular/core";
  import * as React from "react";
  import * as ReactDOM from "react-dom";
  import SuperTokensReactComponent from "./supertokensAuthComponent.tsx";
  
  @Component({
      selector: "app-auth",
      template: '<div [id]="rootId"></div>',
  })
  export class AuthComponent implements AfterViewInit, OnDestroy {
      title = "angularreactapp";
  
      public rootId = "rootId";
  
      // We use the ngAfterViewInit lifecycle hook to render the React component after the Angular component  view gets initialized
      ngAfterViewInit() {
          ReactDOM.render(React.createElement(SuperTokensReactComponent), document.getElementById(this.rootId));
      }
  
      // We use the ngOnDestroy lifecycle hook to unmount the React component when the Angular wrapper component is destroyed.
      ngOnDestroy() {
          ReactDOM.unmountComponentAtNode(document.getElementById(this.rootId) as Element);
      }
  }

• Initialize the supertokens-auth-react SDK in your angular app's root component. This will provide session management across your entire application.

  /app/app.component.ts

  import { Component } from "@angular/core";
  
  import * as SuperTokens from "supertokens-auth-react";
  import * as EmailPassword from "supertokens-auth-react/recipe/emailpassword";
  import Session from "supertokens-auth-react/recipe/session";
  
  SuperTokens.init({
      appInfo: {
          appName: "<YOUR_APP_NAME>",
          apiDomain: "<YOUR_API_DOMAIN>",
          websiteDomain: "<YOUR_WEBSITE_DOMAIN>",
          apiBasePath: "/auth",
          websiteBasePath: "/auth"
      },
      recipeList: [
          EmailPassword.init(),
          Session.init(),
      ],
  });
  
  @Component({
      selector: "app-root",
      template: "<router-outlet></router-outlet>",
  })
  export class AppComponent {
      title = "<YOUR_APP_NAME>";
  }

Vue

Before we initialize the supertokens-auth-react SDK let's see how we will use it in our Vue app

Architecture

• The supertokens-auth-react SDK is responsible for rendering the login UI, handling authentication flows and session management.
• Using supertokens-auth-react's pre-built UI does not increase application's bundle size. React is only added to authentication-related routes.

Creating the /auth route

• Create a new file AuthView.vue, this Vue component will be used to render the auth component

• Create a React component Supertokens.tsx. This will tell SuperTokens which UI to show when the user visits the login page.

  /components/Supertokens.tsx

  import * as SuperTokens from "supertokens-auth-react";
  import { canHandleRoute, getRoutingComponent } from "supertokens-auth-react/ui";
  import { EmailPasswordPreBuiltUI } from "supertokens-auth-react/recipe/emailpassword/prebuiltui";
  
  function SuperTokensReactComponent(props: any) {
     if (canHandleRoute([EmailPasswordPreBuiltUI])) {  
          return getRoutingComponent([EmailPasswordPreBuiltUI]);
      }
      return "Route not found";
  }
  
  export default SuperTokensReactComponent;

• Load SuperTokensReactComponent in the AuthView.vue component

  /views/AuthView.vue

  <script lang="ts">
  import * as React from "react";
  import * as ReactDOM from "react-dom";
  import SuperTokensReactComponent from "../components/Supertokens";
  export default {
      mounted: () => {
          ReactDOM.render(
              React.createElement(SuperTokensReactComponent as React.FC),
              document.getElementById("authId")
          );
      }
  };
  </script>
  
  <template>
      <main>
          <div id="authId" />
      </main>
  </template>

• Initialize the supertokens-auth-react SDK in your Vue app's main.ts file. This will provide session management across your entire application.

  /main.ts

  import { createApp } from "vue";
  import * as SuperTokens from "supertokens-auth-react";
  import * as EmailPassword from "supertokens-auth-react/recipe/emailpassword";
  import Session from "supertokens-auth-react/recipe/session";
  import App from "./App.vue";
  import router from "./router";
  
  SuperTokens.init({
      appInfo: {
          appName: "<YOUR_APP_NAME>",
          apiDomain: "<YOUR_API_DOMAIN>",
          websiteDomain: "<YOUR_WEBSITE_DOMAIN>",
          apiBasePath: "/auth",
          websiteBasePath: "/auth"
      },
      recipeList: [
          EmailPassword.init(),
          Session.init(),
      ]
  });
  
  const app = createApp(App);
  
  app.use(router);
  
  app.mount("#app");
  

Mobile

important

SuperTokens does not support pre-built UI for mobile frameworks. Please refer to the setup guide for custom UI to integrate SuperTokens in your app.

3) Setup Routing to show the login UI

ReactJS

Do you use react-router-dom?

YesNo

Angular

Update your angular router so that all auth related requests load the auth component

/app/app-routing.module.ts

import { NgModule } from "@angular/core";
import { RouterModule, Routes } from "@angular/router";

const routes: Routes = [
    {
        path: "auth",
        loadChildren: () => import("./auth/auth.module").then((m) => m.AuthModule),
    },

    { path: "**", loadChildren: () => import("./home/home.module").then((m) => m.HomeModule) },
];

@NgModule({
    imports: [RouterModule.forRoot(routes)],
    exports: [RouterModule],
})
export class AppRoutingModule {}

Vue

Update your Vue router so that all auth related requests load the AuthView component

/router/index.ts

import { createRouter, createWebHistory } from "vue-router";
import HomeView from "../views/HomeView.vue";

const router = createRouter({
    history: createWebHistory(import.meta.env.BASE_URL),
    routes: [
        {
            path: "/",
            name: "home",
            component: HomeView,
        },
        {
            path: "/auth*",
            name: "auth",
            component: () => import("../views/AuthView.vue"),
        },
    ],
});

export default router;

Mobile
