Validation

These packages are capable of validating the data for type correctness.

E.g. if string was expected, but a number was provided, the validator should fail.

Interface

It has a validator function or method that returns a valid type casted value or throws.

const data: any = {};

// `res` is now type casted to the right type
const res = isValid(data);

Or it has a type guard function that in a truthy block type casts the value.

const data: any = {};

function isMyDataValid(data: any) {
  // isValidGuard is the type guard function provided by the package
  if (isValidGuard(data)) {
    // data here is "guarded" and therefore inferred to be of the right type
    return data;
  }

  throw new Error('Invalid!');
}

// `res` is now type casted to the right type
const res = isMyDataValid(data);
