Create a complete web app with a backend and deploy it in less than 5 minutes.
Here are the steps 👇
1. Prepare the prompt
I use GPT "Prompt Enhancer" to save time (FR€E ACCESS LINK IS IN MY LAST COMMENT BELOW)
It transformed my basic prompt into a much more complete prompt so that o3 could one-shot the app.
Prompt:
"You're a senior front-end developer with experience in building productivity tools using vanilla JavaScript and browser-based storage. Create a single-file web application that serves as a "Prompt Organizer" to help users save, edit, delete, and categorize AI prompts directly in the browser without any external dependencies. Use only HTML, CSS, and JavaScript, and store data persistently using localStorage or IndexedDB to ensure saved prompts remain available across sessions. Each prompt should include fields such as title, description, tags, and the full prompt text. Users should be able to filter prompts by tags, search by keywords, and sort by date created or modified. Include example prompts to populate the organizer on first load. Structure the code so it’s readable and modular within the single HTML file, using internal <style> and <script> tags. Use a clean, modern UI design with a light color palette, clear typography, and responsive layout. Adopt an approachable and user-friendly tone throughout the UI, with intuitive labels, buttons, and helpful tooltips."
2. Use o3
Paste the enhanced prompt into a new ChatGPT conversation.
Select “o3” as the model and activate the “Canvas” option.
3. Preview your app
Use the "Preview" option to view your app.
You can use some features, but not yet the "database". Ask o3 to make changes if you want.
4. Save the app
Copy the code and paste it into a text file.
Save it in ".html" format. For example, "myapp.html".
5. Use your new app
Just open your HTML file to launch the app. You're ready to go!
And all changes are saved in your app's database.
So even if you refresh the page or close/open the app, everything stays saved!
6. Deploy your app
If you want to make your app accessible to others, you need to deploy it.
