Build a CRUD app in your browser with mobileCoder
A CRUD app lets people create, read, update, and delete records, and it is one of the fastest things to build in mobileCoder. Describe what you need and the agent builds and runs it, so you can test it in a live preview.
What a CRUD app is and why it is a good first build
CRUD stands for create, read, update, and delete. Most everyday software is a CRUD app underneath: a task list, a contacts book, an inventory tracker, a simple booking tool. You have records, you add to them, you edit them, and you remove them.
These apps are a strong first project because the shape is predictable. Once you can describe the records you want to store and the fields on each record, the agent has enough to build screens for viewing a list, opening a single item, adding a new one, and editing or deleting an existing one.
Everything runs in the browser. There is no local setup, no toolchain to install, and nothing to configure before you start. You open mobileCoder, describe the app, and the agent gets to work.
Describe your data model in plain language
Start with the records. Tell the agent what you are tracking and what each field holds. For a contacts app you might say you want a name, an email, a phone number, a company, and a note.
- Name the record type so the agent knows what one item represents, such as a contact, a task, or a product.
- List the fields and roughly what kind of value each one holds, such as text, a number, a date, or a yes or no flag.
- Mention required fields if some values must always be present.
You do not need to know database terms to do this. Plain sentences work. If you leave something out, you can ask for it later and the agent will adjust the app.
Let the agent build and run the app
Once you have described the records, the agent builds the app: the data model, the forms for adding and editing, the list view, and the actions to update and delete. It then runs the app so a live preview appears.
This is the moment to actually use it. Add a record. Edit it. Delete it. Reload and confirm the data behaves the way you expect. Working with the running app tells you far more than reading a description of it.
If something is missing or wrong, describe the change. You might ask for a search box, a way to sort the list, or an extra field. The agent updates the app and runs it again.
Review the code before you rely on it
AI generated code can be wrong or incomplete, so treat the first working version as a draft, not a finished product. mobileCoder lets you review the code the agent wrote, which matters as soon as the app does anything you care about.
- Check how records are validated so bad or empty input does not slip through.
- Test the delete action and confirm it removes the right record and nothing else.
- Try edge cases such as very long text, duplicate entries, and empty fields.
Reading the code also helps you learn. Over a few builds you start to recognize how the pieces fit together, which makes your next request sharper.
Grow the app one request at a time
A CRUD core is a foundation you can extend. Once the basics work, add features in small steps so each one is easy to test.
- Add filtering or a search field to find records quickly.
- Add categories or tags to group records.
- Add a detail page that shows one record with more room.
- Bring in an outside service using your own keys in the Secrets panel when you need email, payments, or data from another API.
Small, testable changes keep the app stable and make it clear which request caused which result.
