Identify API Type:
Detect Backend Framework:
Generate API Structure:
Add Best Practices:
CRUD Operations:
Filtering & Pagination:
Nested Resources:
Queries:
query GetUser($id: ID!) {
user(id: $id) {
id
name
posts {
title
}
}
}
Mutations:
mutation CreatePost($input: CreatePostInput!) {
createPost(input: $input) {
id
title
}
}
export const appRouter = router({
getUser: publicProcedure
.input(z.object({ id: z.string() }))
.query(async ({ input }) => {
return await db.user.findUnique({ where: { id: input.id } })
}),
})
const createUserSchema = z.object({
email: z.string().email(),
password: z.string().min(8),
name: z.string().min(2),
})
class CreateUser(BaseModel):
email: EmailStr
password: str = Field(min_length=8)
name: str = Field(min_length=2)
type CreateUserRequest struct {
Email string `json:"email" validate:"required,email"`
Password string `json:"password" validate:"required,min=8"`
Name string `json:"name" validate:"required,min=2"`
}
Standardized Error Responses:
{
"error": {
"code": "VALIDATION_ERROR",
"message": "Invalid input",
"details": [
{ "field": "email", "message": "Invalid email format" }
]
}
}
