TypeScript Node.js Next.js .cursorrules prompt file

You are an expert in TypeScript, Node.js, Next.js App Router, React, Prisma, PostgreSQL, Turborepo, Shadcn UI, Radix UI and Tailwind.

Write concise, technical TypeScript code with accurate examples.
Use functional and declarative programming patterns; avoid classes.
Prefer iteration and modularization over code duplication. But if you don't have a proper abstraction then writing similar code twice is fine.
Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
Structure files: exported component, subcomponents, helpers, static content, types.
Use kebab case for route directories (e.g., api/hello-world/route). Use PascalCase for components (eg. components/Button.tsx)
Shadcn components are in components/ui. All other components are in components/.
Colocate files in the folder they're used. Unless the component can be used in many places across the app. Then it can be placed in the components folder.
We use Turborepo with pnpm workspaces.
We have one app called web in apps/web.
We have packages in the packages folder.
We have Next.js server actions in the apps/web/utils/actions folder. Eg. apps/web/utils/actions/cold-email has actions related to cold email management.
Favor named exports for components.
Use TypeScript for all code.
Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
Use Shadcn UI and Tailwind for components and styling.
Implement responsive design with Tailwind CSS; use a mobile-first approach.
Use next/image package for images.
For API get requests to server use the swr package. Example:
```typescript
const searchParams = useSearchParams();
const page = searchParams.get("page") || "1";
const { data, isLoading, error } = useSWR<PlanHistoryResponse>(
/api/user/planned/history?page=${page}
);
```
Use the Loading component. Example:
```tsx
<Card>
<LoadingContent loading={isLoading} error={error}>
{data && <MyComponent data={data} />}
</LoadingContent>
</Card>
```
If we're in a server file, you can fetch the data inline.
For mutating data, use Next.js server actions.
Use isActionError with toastError and toastSuccess. Success toast is optional. Example:
```typescript
import { toastError, toastSuccess } from "@/components/Toast";
const onSubmit: SubmitHandler<TestRulesInputs> = useCallback(async (data) => {
const result = await testAiCustomContentAction({ content: data.message });
if (isActionError(result)) {
toastError({
title: "Error testing email",
description: result.error,
});
} else {
toastSuccess({ description: "Saved!" });
}
}, []);
```
Implement type-safe server actions with proper validation.
Define input schemas using Zod for robust type checking and validation.
Handle errors gracefully and return appropriate responses.
Ensure all server actions return the Promise`` type
Use React Hook Form with Zod for validation. The same validation should be done in the server action too. Example:
```tsx
export const ProcessHistory = () => {
const {
register,
handleSubmit,
formState: { errors, isSubmitting },
} = useForm<ProcessHistoryOptions>({
resolver: zodResolver(processHistorySchema),
});
const onSubmit: SubmitHandler<ProcessHistoryOptions> = useCallback(
async (data) => {
const result = await processHistoryAction(data.email);
handleActionResult(result, Processed history for ${data.email});
},
[]
);
return (
<form className="max-w-sm space-y-4" onSubmit={handleSubmit(onSubmit)}>
`<Input
type="email"
name="email"
label="Email"
registerProps={register("email", { required: true })}
error={errors.email}
/>`
<Button type="submit" loading={isSubmitting}>
Process History
</Button>
</form>
);
};
```
This is how you do a text area. Example:
```tsx
`<Input
type="text"
as="textarea"
rows={3}
name="message"
placeholder="Paste in email content"
registerProps={register("message", { required: true })}
error={errors.message}
/>`
```
This is the format of a server action. Example:
```typescript
export const deactivateApiKeyAction = withActionInstrumentation(
"deactivateApiKey",
async (unsafeData: DeactivateApiKeyBody) => {
const session = await auth();
const userId = session?.user.id;
if (!userId) return { error: "Not logged in" };
```
const { data, success, error } =  deactivateApiKeyBody.safeParse(unsafeData);if (!success) return { error: error.message };await prisma.apiKey.update({  where: { id: data.id, userId },  data: { isActive: false },});revalidatePath("/settings");
```
}
);
```

Key Principles

Write concise, technical responses with accurate TypeScript examples.
Use functional, declarative programming. Avoid classes.
Prefer iteration and modularization over duplication.
Use descriptive variable names with auxiliary verbs (e.g., isLoading).
Use lowercase with dashes for directories (e.g., components/auth-wizard).
Favor named exports for components.
Use the Receive an Object, Return an Object (RORO) pattern.

JavaScript/TypeScript
Use "function" keyword for pure functions. Omit semicolons.
Use TypeScript for all code. Prefer interfaces over types. Avoid enums, use maps.
File structure: Exported component, subcomponents, helpers, static content, types.
Avoid unnecessary curly braces in conditional statements.
For single-line statements in conditionals, omit curly braces.
Use concise, one-line syntax for simple conditional statements (e.g., if (condition) doSomething()).

Error Handling and Validation
Prioritize error handling and edge cases:
Handle errors and edge cases at the beginning of functions.
Use early returns for error conditions to avoid deeply nested if statements.
Place the happy path last in the function for improved readability.
Avoid unnecessary else statements; use if-return pattern instead.
Use guard clauses to handle preconditions and invalid states early.
Implement proper error logging and user-friendly error messages.
Consider using custom error types or error factories for consistent error handling.
