How to Build a Custom Party Planning App with Lovable and Midjourney

Build a small event hub that centralizes guests, dishes, recipes, and photos, then personalize it with intentional typography and art while making dietary information clear and usable.

How to Build a Custom Party Planning App with Lovable and Midjourney

Claire builds a Thanksgiving hub in Lovable, replaces its generic typography and hero art, repairs visual issues with screenshots, then adds dietary preferences and dish tags.

Before you start

What you need

  • An event name, date, location, and host
  • Guest, dish, recipe, and photo-sharing needs
  • A chosen type pairing and licensed or generated artwork
  • A list of dietary preferences and allergen categories
  • A decision about authentication, privacy, and who may edit

What you’ll make

A responsive party hub where invited guests can coordinate attendance and dishes, understand dietary labels, and share approved event content.

Tools used

Step by step

The workflow

Follow the sequence once, then adapt the prompts, checks, and handoffs to your own setup.

5 steps

Step01

Generate the Basic App Structure

Start with a narrow Lovable prompt for the event, guest list, dish coordination, recipe links, and optional photo gallery. State who can view and edit each section.

Example prompt
Build a responsive party hub for [event]. Include invitation status, a guest-editable dish list, recipe links, and an optional photo gallery. Keep the first version small. Do not expose guest contact details publicly, and use placeholder data until access rules are configured.
Step02

Improve Typography with Google Fonts

Choose a readable Google Fonts pairing and ask Lovable to apply the display face only where appropriate. Test loading, fallback fonts, long headings, and mobile sizes.

Example prompt
Use [display font] for short headings and [body font] for navigation, labels, buttons, and body copy. Load both through the supported font integration, preserve readable line height and contrast, and provide system fallbacks.

You can inspect the files in Lovable to see how it adds the Google Fonts API and configures the CSS, which is a great way to learn front-end best practices.

Step03

Design and Implement a Custom Header

Create or license a wide hero image, record its usage rights and prompt, upload an optimized version, and update the title and event copy. Add a contrast overlay and responsive focal point.

Example prompt
Use this approved image as the event hero. Keep the focal point visible from mobile through desktop, add sufficient text contrast, provide descriptive alt text when the image is meaningful, and personalize the title and copy with these facts: [facts].
Step04

Add Custom Features for Dietary Needs

Add dietary preferences and allergies to each guest with a controlled multi-select plus a free-text “other” field. Explain that entries communicate needs but do not guarantee food safety.

Example prompt
Let's add dietary preferences, restrictions to the guest list. Let's start with a multi-select of the most common ones.
Step05

Connect Custom Features

Let dish contributors select ingredients, dietary labels, common allergens, and cross-contact uncertainty. Show which guests may have a conflict and direct them to confirm with the cook rather than declaring a dish safe.

Example prompt
Connect guest dietary entries with dish ingredient and allergen tags. Show “matches preference,” “possible conflict,” or “ask the cook.” Never label a dish allergy-safe solely from generated data, and let the dish owner correct every tag.

What good looks like

  • The core guest and dish flows work before visual customization.
  • Typography remains readable and the hero image works across screen sizes.
  • Dietary and allergen tags are explicit, consistent, and editable by the dish owner.
  • Guest contact details and photos are visible only to the intended audience.

How to recover when the loop fails and where human judgment helps.

Recover

If it goes sideways

The first prompt produces a large event platform instead of a useful party hub
Cut the scope to guests, dishes, recipes, and optional photos, then complete one end-to-end flow before adding features.
The custom font or hero makes text hard to read
Limit display type to headings, add a stable contrast treatment, and test long titles and mobile crops.
A generated tag implies that a dish is safe when ingredients or cross-contact are uncertain
Require the contributor to confirm ingredients, distinguish preference from allergy, and display an uncertainty or ask-the-cook state.
Guest emails or private photos become public
Require access control, minimize collected fields, and test the page while signed out before sharing it.
