CRUD
CRUD stands for Create, Read, Update, Delete — the four basic operations for managing data in any application. Most features in a web app are CRUD operations at their core: creating a user account, reading a list of products, updating a profile, deleting a post. AI generates CRUD code extremely well.
Example
A blog application is pure CRUD: Create a new post, Read posts on the homepage, Update an existing post in the editor, Delete posts you don't want anymore. These four operations cover the entire feature set.
CRUD is the skeleton of almost every web application. Once you recognize the pattern, you see it everywhere — and AI can generate it almost instantly.
The Four Operations
| Operation | SQL | HTTP Method | Example |
|---|---|---|---|
| Create | INSERT | POST | Add a new user |
| Read | SELECT | GET | View a product list |
| Update | UPDATE | PUT/PATCH | Edit profile settings |
| Delete | DELETE | DELETE | Remove a comment |
CRUD in Real Applications
| Application | Create | Read | Update | Delete |
|---|---|---|---|---|
| Twitter/X | Post a tweet | View feed | Edit tweet | Delete tweet |
| Shopify | Add product | Browse catalog | Update price | Remove product |
| Gmail | Compose email | Read inbox | Edit draft | Delete email |
CRUD and Vibe Coding
CRUD is where AI delivers the most consistent results. The pattern is so well-established that AI generates it reliably:
- Describe the resource — "I need CRUD for blog posts"
- AI generates everything — Database schema, API routes, UI forms
- Customize — Add your specific business logic
- Repeat — Most apps are multiple CRUD resources connected together
Beyond CRUD
Not everything fits neatly into CRUD. Some operations are more complex:
- Search and filter — A specialized form of Read
- Bulk operations — Acting on many records at once
- Workflows — Multi-step processes with state changes
- Real-time updates — Data that changes without refreshing
Start with CRUD, then add complexity where needed.
