Form Validation

React Hook Form Integration

// hooks/use-form-validation.ts import { useForm } from "react-hook-form"; import { zodResolver } from "@hookform/resolvers/zod"; import { z } from "zod";

// Example schema const userSchema = z.object({ username: z.string().min(2, "Username must be at least 2 characters"), email: z.string().email("Please enter a valid email"), password: z.string().min(8, "Password must be at least 8 characters"), confirmPassword: z.string().refine( (data) => data.password === data.confirmPassword, { message: "Passwords don't match", path: ["confirmPassword"], } ), });

type UserFormData = z.infer<typeof userSchema>;

export function useUserForm() { return useForm<UserFormData>({ resolver: zodResolver(userSchema), defaultValues: { username: "", email: "", password: "", confirmPassword: "", }, mode: "onBlur", }); }

// Custom validation hook export function useFormValidation<T extends Record<string, any>>( schema: z.ZodSchema<T>, defaultValues?: Partial<T> ) { return useForm<T>({ resolver: zodResolver(schema), defaultValues, mode: "onBlur", }); }

Utility Functions

cn utility

// lib/utils.ts import { type ClassValue, clsx } from "clsx"; import { twMerge } from "tailwind-merge";

export function cn(...inputs: ClassValue[]) { return twMerge(clsx(inputs)); }

// Format utilities export function formatBytes( bytes: number, opts: { decimals?: number; sizeType?: "accurate" | "normal"; } = {} ) { const { decimals = 0, sizeType = "normal" } = opts;

const sizes = ["Bytes", "KB", "MB", "GB", "TB"]; const accurateSizes = ["Bytes", "KiB", "MiB", "GiB", "TiB"]; if (bytes === 0) return "0 Bytes"; const i = Math.floor(Math.log(bytes) / Math.log(1024)); return ${(bytes / Math.pow(1024, i)).toFixed(decimals)} ${ sizeType === "accurate" ? accurateSizes[i] ?? "Bytes" : sizes[i] ?? "Bytes" }; }

// Date utilities export function formatDate(date: Date | string | number) { return new Intl.DateTimeFormat("en-US", { month: "long", day: "numeric", year: "numeric", }).format(new Date(date)); }

Usage Examples

Form Implementation

// components/forms/user-form.tsx import { useUserForm } from "@/hooks/use-form-validation"; import { Button } from "@/components/ui/button"; import { Input } from "@/components/ui/input"; import { Label } from "@/components/ui/label"; import { Form, FormControl, FormDescription, FormField, FormItem, FormLabel, FormMessage, } from "@/components/ui/form";

export function UserRegistrationForm() { const form = useUserForm();

function onSubmit(values: UserFormData) { console.log(values); // Handle form submission }

return ( <Form {...form}> <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-8"> <FormField control={form.control} name="username" render={({ field }) => ( <FormItem> <FormLabel>Username</FormLabel> <FormControl> <Input placeholder="Enter username" {...field} /> </FormControl> <FormDescription> This is your public display name. </FormDescription> <FormMessage /> </FormItem> )} />

    <FormField
      control={form.control}
      name="email"
      render={({ field }) => (
        <FormItem>
          <FormLabel>Email</FormLabel>
          <FormControl>
            <Input type="email" placeholder="Enter email" {...field} />
          </FormControl>
          <FormMessage />
        </FormItem>
      )}
    />

    <FormField
      control={form.control}
      name="password"
      render={({ field }) => (
        <FormItem>
          <FormLabel>Password</FormLabel>
          <FormControl>
            <Input type="password" placeholder="Enter password" {...field} />
          </FormControl>
          <FormMessage />
        </FormItem>
      )}
    />

    <Button type="submit">Register</Button>
  </form>
</Form>

); }

Accessibility Features

ARIA Labels and Roles

// components/ui/accessible-button.tsx import { forwardRef } from "react"; import { Button } from "./button";

interface AccessibleButtonProps { children: React.ReactNode; ariaLabel?: string; ariaDescribedBy?: string; isLoading?: boolean; disabled?: boolean; }

export const AccessibleButton = forwardRef<HTMLButtonElement, AccessibleButtonProps>( ({ children, ariaLabel, ariaDescribedBy, isLoading, disabled, ...props }, ref) => { return ( <Button ref={ref} disabled={disabled || isLoading} aria-label={ariaLabel} aria-describedby={ariaDescribedBy} aria-busy={isLoading} {...props} > {isLoading && ( <span className="mr-2" aria-hidden="true"> <div className="h-4 w-4 animate-spin rounded-full border-2 border-current border-t-transparent" /> </span> )} {children} </Button> ); } );

Performance Optimization

Lazy Loading Components

// components/ui/lazy-component.tsx import dynamic from "next/dynamic";

export const LazyChart = dynamic( () => import("recharts").then((mod) => mod.LineChart), { loading: () => <div className="h-64 w-full animate-pulse bg-muted" />, ssr: false, } );

export const LazyDataTable = dynamic( () => import("./data-table").then((mod) => mod.DataTable), { loading: () => <div className="h-96 w-full animate-pulse bg-muted" />, ssr: false, } );
