How to integrate Lovable with Okta?

Adding the Okta Library via a Script Tag

Open your Lovable project's main HTML file (for example, index.html).
Insert the following script tag in the <head> section to load Okta’s Auth JS library:
```
    
```

Creating the Okta Configuration File

Create a new file in your project’s source directory named okta-config.ts.
Paste the following code into okta-config.ts to define your Okta settings. Replace YOUROKTACLIENTID and YOUROKTA_DOMAIN with your actual Okta details:


// okta-config.ts
export const oktaConfig = {
  clientId: 'YOUROKTACLIENT_ID',
  issuer: 'https://YOUROKTADOMAIN/oauth2/default',
  redirectUri: window.location.origin + '/login/callback',
  scopes: ['openid', 'profile', 'email']
};

Creating the Okta Authentication Service

Create a new file named okta-auth.service.ts in your source directory.
Insert the following TypeScript code, which declares an OktaAuthService class that handles sign-in, sign-out, and authentication checks:


import { oktaConfig } from './okta-config';

declare const OktaAuth: any;
export class OktaAuthService {
  private oktaAuth: any;
  constructor() {
    this.oktaAuth = new OktaAuth({
      clientId: oktaConfig.clientId,
      issuer: oktaConfig.issuer,
      redirectUri: oktaConfig.redirectUri,
      scopes: oktaConfig.scopes
    });
  }
  async signIn(username: string, password: string): Promise {
    try {
      const transaction = await this.oktaAuth.signIn({ username, password });
      if (transaction.status === 'SUCCESS') {
        // Tokens can be stored or further actions done here
        return transaction;
      }
    } catch (err) {
      console.error('Sign in failed', err);
      throw err;
    }
  }
  async isAuthenticated(): Promise {
    return await this.oktaAuth.isAuthenticated();
  }
  async signOut(): Promise {
    await this.oktaAuth.signOut();
  }
}

Integrating Okta Authentication in Your Main Application Code

Open your main application file (for example, app.ts).
Add the following code to import and use the OktaAuthService. This example assumes you have a login button with the ID loginBtn and input fields with the IDs username and password:


import { OktaAuthService } from './okta-auth.service';

const authService = new OktaAuthService();
// Example: Adding a click event listener to the login button
const loginButton = document.getElementById('loginBtn');
if (loginButton) {
  loginButton.addEventListener('click', async () => {
    const usernameInput = (document.getElementById('username') as HTMLInputElement).value;
    const passwordInput = (document.getElementById('password') as HTMLInputElement).value;
    try {
      const result = await authService.signIn(usernameInput, passwordInput);
      alert('Login Successful!');
      // Redirect or update your UI as needed
    } catch (error) {
      alert('Login Failed: ' + error.message);
    }
  });
}

Adding the Login Form to Your HTML

Update your main HTML file (for example, index.html) to include a login form. Insert the following code snippet in the body section where you want the login form to appear:
```
  
  
  

    
```

Final Integration Check

Ensure that all the new files (okta-config.ts and okta-auth.service.ts) are saved in your project’s source directory.
Verify that the script tag in your HTML file is correctly placed and that the login form is present.
Your Okta integration is now ready in your Lovable project.
