Easy create body validations using Validator.lang!
This package is still in development, so it may have some bugs.
import { SimpleValidator } from 'validatorlang'
const validator = new SimpleValidator(`
Validator {
string name @minLength(5) @maxLength(20)
number age @optional
bool isAdult
Adress adress
}
Address {
string state
string city
string street
number number
}
`).build();
const result = validator.validate({
name: 'John',
age: 20,
isAdult: true
});
if (result !== true) throw result;- Add more annotations and types
- Add array support
- Finish Advanced validator
- Add support for enums
- Add support for building validators from a directory
- Add types for typescript for builded validators
- Add support for maps / dictionaries
- Better error handling for ParseErrors
- Macros (ex: macro string Username @minLength(3) @maxLength(20) @pattern(/^[a-z0-9_]+$/i))
Checks if the value is a string.
Annotations:
@minLength(int size) - Minimum length of the string
@maxLength(int size) - Maximum length of the string
@pattern(Regex regex) - Checks if the string matches the regex
@containsLowercase - Checks if the string contains a lowercase letter
@containsUppercase - Checks if the string contains a uppercase letter
@containsNumber - Checks if the string contains a number
@containsSpecial - Checks if the string contains a special character
Checks if the value is a number.
Annotations:
@min(int size) - Minimum value of the number
@max(int size) - Maximum value of the number
@integer - Checks if the number is an integer
@notNan - checks if the number is not NaN
@positive - Checks if the number is positive
@negative - Checks if the number is negative
Checks if the value is a boolean.
Checks if the value is an object.
Checks if the value is an Array.
Annotations:
@minLength(int size) - Minimum length of the array
@maxLength(int size) - Maximum length of the array
@item:(annotation) - Checks the annotation on the array items, this is specific per type
-- Example: @item:@minLength(5)
@optional - Makes the type optional (has no default implementation, must be handled by the Type)
