+A standard interface for TypeScript schema validation libraries
+
+[![npm](https://img.shields.io/bundlephobia/minzip/@standard-schema/spec?style=for-the-badge)](https://bundlephobia.com/result?p=@standard-schema/spec)
+
+Example zod
+
+```typescript jsx
+import { useForm } from 'react-hook-form';
+import { standardSchemaResolver } from '@hookform/resolvers/standard-schema';
+import { z } from 'zod';
+
+const schema = z.object({
+  name: z.string().min(1, { message: 'Required' }),
+  age: z.number().min(10),
+});
+
+const App = () => {
+  const {
+    register,
+    handleSubmit,
+    formState: { errors },
+  } = useForm({
+    resolver: standardSchemaResolver(schema),
+  });
+
+  return (
+    <form onSubmit={handleSubmit((d) => console.log(d))}>
+      <input {...register('name')} />
+      {errors.name?.message && <p>{errors.name?.message}</p>}
+      <input type="number" {...register('age', { valueAsNumber: true })} />
+      {errors.age?.message && <p>{errors.age?.message}</p>}
+      <input type="submit" />
+    </form>
+  );
+};

+
+Example arkType
+
+```typescript jsx
+import { useForm } from 'react-hook-form';
+import { standardSchemaResolver } from '@hookform/resolvers/standard-schema';
+import { type } from 'arktype';
+
+const schema = type({
+  username: 'string>1',
+  password: 'string>1',
+});
+
+const App = () => {
+  const { register, handleSubmit } = useForm({

+  });
+
+  return (
+    <form onSubmit={handleSubmit((d) => console.log(d))}>
+      <input {...register('username')} />
+      <input type="password" {...register('password')} />
+      <input type="submit" />
