Summary written by us from the video's transcript. The video, and everything in it, is Tech With Tim's work.

Learn how to use Lovable with a Superbase backend to build, design, add authentication, and deploy a functional web app from scratch.

Takeaways

  • Lovable generates complete front‑end code from natural language prompts, eliminating manual coding for visual layouts.
  • Connecting an external Superbase project gives you ownership of the database, authentication, and storage instead of using Lovable’s internal cloud.
  • Prompt structure (purpose, users, features, exclusions, design) guides the AI to produce accurate app scaffolding.
  • Use *plan mode* for major feature additions like auth; Lovable provides a detailed implementation plan you can follow step‑by‑step.
  • The built‑in **/redesign** skill and history panel let you quickly iterate UI designs without leaving the platform.

What is Lovable and How It Works

Lovable is an AI‑powered web app builder that generates full React, HTML, JavaScript, and CSS code from natural‑language prompts. You can use it without writing any code, or you can export the generated project to GitHub for further customization.

The platform now supports server‑side rendering, which improves SEO, and it integrates with external services like Superbase, Stripe, and Shopify through built‑in connectors.

Setting Up a Free Lovable Account and Workspace

Create a free Lovable account (credits are provided on sign‑up) and open a workspace. From the dashboard click **Create Project** to start a new app.

Switch to *build mode* and prepare to connect an external backend before adding any prompts.

Connecting a Superbase Backend

In Lovable’s UI press the plus button, choose **Databases**, and add a **Superbase organization**. If the connector isn’t visible, enable it under the left‑hand *Connectors* menu along with Stripe or Shopify if needed.

Create a free Superbase account, add a new project (choose region, generate a password, enable automatic roles), then return to Lovable and select that Superbase project as your database. This gives you full control over the backend instead of using Lovable’s internal cloud instance.

Writing Your First Prompt

Structure prompts by describing: 1) the app purpose, 2) target users, 3) core features to build, 4) features to exclude, and 5) design style. Example used in the video: a “Feedback Hub” board where admins create boards, users post feedback, and votes are displayed; no comments, payments, or AI features at this stage.

Submit the prompt; if the build fails, use the **Try to fix** button while reviewing the preview pane, file list, and code tab for diagnostics.

Iterating Design with the Redesign Skill

Use the built‑in **/redesign** skill (type a slash) to request a fresh visual style. Provide vague guidance like “modern, sleek, abstract” and let Lovable regenerate UI components.

The side panel shows history, allowing you to revert to earlier versions if needed, and offers palette selection widgets that appear when prompted.

Adding Authentication via Plan Mode

Switch to *plan mode* before major changes. Prompt Lovable to add Google sign‑in using the connected Superbase database and to create a matching schema for boards, votes, and feedback entries.

Lovable returns a step‑by‑step plan; follow its instructions to configure Google OAuth in the Superbase dashboard (create a Google Cloud project, set up OAuth consent screen, add authorized domains, generate client ID/secret, and paste them back into Superbase).

Deploying the Completed App

Once authentication and schema are live, test the app: create boards, submit feedback, and see data persist across refreshes.

Lovable can then publish the site to a custom domain; the backend remains hosted on Superbase, giving you full control and the ability to scale or migrate later.
