# GraphQL Patterns
|
|
|
|
## Code Generation
|
|
|
|
- **Generated types** from GraphQL schema
|
|
- **Typed hooks** from @vue/apollo-composable
|
|
- **Fragment colocation** with components
|
|
- **Operation naming** follows schema conventions
|
|
|
|
## Fragment-Based Architecture
|
|
|
|
```typescript
|
|
// Define component data requirements via fragments
|
|
graphql(`
|
|
fragment SomeComponent_Project on Project {
|
|
id
|
|
name
|
|
# Only fields this component needs
|
|
}
|
|
`)
|
|
|
|
defineProps<{
|
|
project: SomeComponent_Project
|
|
}>()
|
|
```
|
|
|
|
## Query/Mutation Patterns
|
|
|
|
```typescript
|
|
// Use generated hooks
|
|
const { result, loading, error } = useQuery(SomeQuery)
|
|
const { mutate, loading: mutating } = useMutation(SomeMutation)
|
|
|
|
// Handle loading states
|
|
const isLoading = computed(() => loading.value || mutating.value)
|
|
```
|
|
|
|
## Data Requirements
|
|
|
|
- **Always include `id` field** in queries for Apollo cache management
|
|
- **Mutations return updated objects** instead of just success booleans
|
|
- **Use fragments** to define component data requirements
|
|
- **Fragment naming**: `{ComponentName}_{GraphQLType}`
|
|
|
|
## Examples
|
|
|
|
### Fragment Definition
|
|
|
|
```typescript
|
|
// UserCard.vue
|
|
graphql(`
|
|
fragment UserCard_User on User {
|
|
id
|
|
name
|
|
email
|
|
avatar
|
|
}
|
|
`)
|
|
|
|
defineProps<{
|
|
user: UserCard_User
|
|
}>()
|
|
```
|
|
|
|
### Query with Fragments
|
|
|
|
```typescript
|
|
// UsersPage.vue
|
|
const { result: usersResult } = useQuery(
|
|
graphql(`
|
|
query UsersPage_Users {
|
|
users {
|
|
id
|
|
...UserCard_User
|
|
}
|
|
}
|
|
`)
|
|
)
|
|
```
