Forms and API calls
Collect input, validate it and talk to backends.
📖 Key ideas
- Bind inputs with v-model; use .number and .trim modifiers.
- Validate with simple checks or libraries like VeeValidate.
- Call APIs with fetch or axios inside async functions.
- Track loading and error states in refs.
- Composables (useFetch) package reusable logic.
💡 Real-life example: A composable is a reusable kitchen recipe: any component can cook the same dish the same way.
