import { schema } from '@snps/validation';

const stringSchema = schema.string().required().min(3).max(10);

schema.number()

Creates a number schema.

import { schema } from '@snps/validation';

const numberSchema = schema.number().positive().integer();

schema.boolean()

Creates a boolean schema.

import { schema } from '@snps/validation';

const booleanSchema = schema.boolean().required();

schema.array(itemSchema?: Schema)

Creates an array schema.

import { schema } from '@snps/validation';

const arraySchema = schema.array(schema.string()).min(1);

schema.object(shape?: Record<string, Schema>)

Creates an object schema.

import { schema } from '@snps/validation';

const objectSchema = schema.object({
  name: schema.string().required(),
  age: schema.number().positive().required(),
});

validate(data: unknown, schema: Schema)

Validates data against a schema.

import { schema, validate } from '@snps/validation';

const userSchema = schema.object({
  name: schema.string().required(),
  age: schema.number().positive().required(),
});

const userData = { name: 'John', age: 30 };

const result = await validate(userData, userSchema);

if (result.valid) {
  console.log('Validation successful');
} else {
  console.log('Validation failed:', result.errors);
}
