Which UI do you use?

Custom UI

Pre built UI

Frontend Integration

Supported frameworks

for mobile apps

For mobile apps, please see the "Using your own UI" section (see left nav bar)

Automatic setup using CLI

Run the following command in your terminal.

npx create-supertokens-app@latest --recipe=emailpassword

Once this is done, you can skip Step (1) and (2) in this section (see left nav bar) and move directly to setting up the SuperTokens core (Step 3).

Or, you can manually integrate SuperTokens by following the steps below.

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.

2) Call the init function

ReactJS

In your App.js file, import SuperTokens and call the init function

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-web-js SDK let's see how we will use it in our Angular app

Architecture

• The supertokens-web-js SDK is responsible for session management and providing helper functions to check if a session exists, or validate the access token claims on the frontend (for example, to check for user roles before showing some UI). We will initialise this SDK on the root of your Angular app, so that all pages in your app can use it.
• We will create a /auth* route in the Angular app which will render our pre built UI which will also need to be initialised, but only on that route.

Creating the /auth route

• Use the Angular CLI to generate a new route

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

• Add the following code to your auth angular component

  /app/auth/auth.component.ts

  import { Component, OnDestroy, AfterViewInit, Renderer2, Inject } from "@angular/core";
  import { DOCUMENT } from "@angular/common";
  
  @Component({
      selector: "app-auth",
      template: '<div id="supertokensui"></div>',
  })
  export class AuthComponent implements OnDestroy, AfterViewInit {
  
      constructor(
          private renderer: Renderer2,
          @Inject(DOCUMENT) private document: Document
      ) { }
  
      ngAfterViewInit() {
          this.loadScript('');
      }
  
      ngOnDestroy() {
          // Remove the script when the component is destroyed
          const script = this.document.getElementById('supertokens-script');
          if (script) {
              script.remove();
          }
      }
  
      private loadScript(src: string) {
          const script = this.renderer.createElement('script');
          script.type = 'text/javascript';
          script.src = src;
          script.id = 'supertokens-script';
          script.onload = () => {
              (window as any).supertokensUIInit("supertokensui", {
                  appInfo: {
                      appName: "<YOUR_APP_NAME>",
                      apiDomain: "<YOUR_API_DOMAIN>",
                      websiteDomain: "<YOUR_WEBSITE_DOMAIN>",
                      apiBasePath: "/auth",
                      websiteBasePath: "/auth"
                  },
                  recipeList: [
                      (window as any).supertokensUIEmailPassword.init(),
                      (window as any).supertokensUISession.init(),
                  ],
              });
          }
          this.renderer.appendChild(this.document.body, script);
      }
  }

  • In the loadScript function, we provide the SuperTokens config for the UI. We add the emailpassword and session recipe.

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

  /app/app.component.ts

  import SuperTokens from "supertokens-web-js";
  import Session from "supertokens-web-js/recipe/session";
  
  SuperTokens.init({
      appInfo: {
          appName: "<YOUR_APP_NAME>",
          apiDomain: "<YOUR_API_DOMAIN>",
          apiBasePath: "/auth",
      },
      recipeList: [
          Session.init(),
      ],
  });

Vue

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

Architecture

• The supertokens-web-js SDK is responsible for session management and providing helper functions to check if a session exists, or validate the access token claims on the frontend (for example, to check for user roles before showing some UI). We will initialise this SDK on the root of your Vue app, so that all pages in your app can use it.
• We will create a /auth* route in the Vue app which will render our pre built UI which will also need to be initialised, but only on that route.

Creating the /auth route

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

  <script lang="ts">
      import { defineComponent, onMounted, onUnmounted } from 'vue';
      export default defineComponent({
          setup() {
              const loadScript = (src: string) => {
                  const script = document.createElement('script');
                  script.type = 'text/javascript';
                  script.src = src;
                  script.id = 'supertokens-script';
                  script.onload = () => {
                      (window as any).supertokensUIInit("supertokensui", {
                          appInfo: {
                              appName: "<YOUR_APP_NAME>",
                              apiDomain: "<YOUR_API_DOMAIN>",
                              websiteDomain: "<YOUR_WEBSITE_DOMAIN>",
                              apiBasePath: "/auth",
                              websiteBasePath: "/auth"
                          },
                          recipeList: [
                              (window as any).supertokensUIEmailPassword.init(),
                              (window as any).supertokensUISession.init(),
                          ],
                      });
                  };
                  document.body.appendChild(script);
              };
  
              onMounted(() => {
                  loadScript('');
              });
  
              onUnmounted(() => {
                  const script = document.getElementById('supertokens-script');
                  if (script) {
                      script.remove();
                  }
              });
          },
      });
  </script>
  
  <template>
      <div id="supertokensui" />
  </template>

  • In the loadScript function, we provide the SuperTokens config for the UI. We add the emailpassword and session recipe.

• Initialize the supertokens-web-js 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 SuperTokens from "supertokens-web-js";
  import Session from "supertokens-web-js/recipe/session";
  import App from "./App.vue";
  import router from "./router";
  
  SuperTokens.init({
      appInfo: {
          appName: "<YOUR_APP_NAME>",
          apiDomain: "<YOUR_API_DOMAIN>",
          apiBasePath: "/auth",
      },
      recipeList: [
          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";
import AuthView from "../views/AuthView.vue";

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

export default router;

Mobile
