Naming Conventions
Purpose: Consistent, readable naming patterns (improve clarity, maintainability)
- Keywords: naming, variable, function, class, interface, type, const, camelCase, PascalCase, kebab-case, snake_case
Quick Reference
| Category | Convention | Examples |
|---|---|---|
| Files | kebab-case |
order-form.tsx, checkout-modal.tsx |
| Files (Convex) | snake_case |
convex/stripe_webhook.ts |
| Variables/Functions | camelCase |
selectedAmount, handleSubmit |
| Types/Interfaces | PascalCase |
PaymentMethod, ButtonProps |
| Constants | camelCase + as const |
minOrderAmount |
| Generics | Descriptive | TItem, TData, TError |
| Booleans | Prefixed | isValid, hasError, canSubmit |
| DB/API Fields | snake_case |
transaction_id, _creationTime |
Clear Prefixes
ts
// Functions
function handleSubmit() { }
function getOrderTotal() { }
function isValidEmail() { }
function buildPayload() { }
// Booleans
const isLoading = true
const hasError = false
const canProceed = true
const didComplete = false
const willExpire = true
const shouldRetry = false
Modern Constants
ts
const bitcoinConfirmations = { mainnet: 3 } as const
const paymentMethods = ["card", "bitcoin"] as const
Avoid Old Patterns
ts
// ❌ ALL_CAPS (outdated)
const MAX_AMOUNT = 100
// ❌ Single-letter generics (complex cases)
function map<T, U>(items: T[]): U[]
// ✅ Descriptive generics
function map<TItem, TResult>(items: TItem[]): TResult[]
Named Exports (Default)
ts
// ✅ Prefer named
export function OrderForm() { }
export const config = { }
// Default only when framework requires (Next.js pages)
export default function Page() { }
Convex Exception
Convex requires snake_case for function files:
ts
// ✅ convex/stripe_webhook.ts
// ✅ convex/bitcoin_mutations.ts
Props Naming
ts
interface ButtonProps {
variant: "primary" | "secondary"
onClick: () => void
}
export function Button({ variant, onClick }: ButtonProps) { }
