validaciones: Validaciones NodeJS

Librería de validaciones de diversos tipos en ECMAScript 6. ##Cómo usar

const Validador = require('path/to/util-validador');
//opciones predeterminadas
const validador = new Validador();
//con opciones
let options = {
    logLevel : "debug"
}
const custom = new Validator(options)

function checkJson(myVar) {
    let schema = {
        "type" : "object",
        "properties" : {
            "nombre" : {
                "type" : "string",
                "minLength" : 3,
                "maxLength" : 45
            },
            "apellido" : {
                "type" : "string",
                "pattern": "^(.*)$"
            }           
        }           
    };      
    let result = validador.validateJson(myVar, schema);
    if(result.valid){
        alert("OK!")
    }else{
        for(let m in result.mensaje.split(",")){
            console.error(m);
        }       
        alert("Oh no!")
    }
}

Opciones

log_level

Determina el nivel de logging, utilizando logLevel. Los niveles disponibles son:

• debug
• info
• warn
• error: Valor por defecto
• silent

validation_algorithm

Determina si se usará jsonschema o ajv para validar json al usar validateJson():

• 0: Se utilizará Ajv. Valor por defecto. Ttiene mensajes localizados al español.
• 1: Se utilizará Json-schema.

rut_regex

Expresión regular para realizar la comprobación de formato de rut. Debe ser una expresión regular de javascript, no una string.

Valor por defecto:

 /^(\d{1,3}(?:\.?\d{1,3}){2}-?[\dkK])$/

Funciones

validateJson

Retorna un objeto compuesto de dos valores, "valid" y "mensaje". "valid" es de tipo booleano "mensaje" es string.

Recibe como argumento un objeto json y un objeto schema, basado en la especificación jsonSchema.

Si la validación es positiva, la respuesta tendrá el formato:

{
  "valid" : true,
  "mensaje" : "OK"
}

Si la validación es negativa, tendrá el mismo formato, y los mensajes de error consistirán en una sola string separada por comas.

{
  "valid" : false,
  "mensaje" : "mensaje-1,mensaje-2,mensaje-3"
}

testRegex

Realiza una comparación contra una expresión regular de javascript. Retorna el valor booleano del método test. ####Uso

testRegex("12345", /^\d+$/) === true;

testRegex("12345", /^\d{3}+$/) === false;

isRut

Retorna true si el argumento es una string que contiene un rut.

Ignora los puntos separadores de miles, pero no el guión ni el dígito verificador.

No valida si el dígito verificador es correcto, solo el formato. ####Uso

 isrut("25.636.318-K") === true;
 isrut("19633144-2") === true;
 isrut("19633144") === false;

exists

Retorna true si el argumento no undefined y no es null. ####Uso

const Validador = require('path/to/util-validador');
const v = new Validador();

v.exists(null) === false;
v.exists(undefined) === false;
v.exists(NaN) === true;
v.exists(Infinity) === true;
v.exists("") === true;
v.exists(0) ===true;

isNumber

Retorna true si el valor es un número o una string que pueda ser evaluada como un número.

Valida como verdadero números enteros, reales, binarios, octales, hexadecimales y notación científica.

const Validador = require('path/to/util-validador');
const v = new Validador();
####Uso
v.isNumber(42) === true;
v.isNumber(-42) === true;
v.isNumber(42.5) === true;
v.isNumber(0b101010) === true;
v.isNumber(0o52) === true;
v.isNumber(0x2A) === true;

v.isNumber(-4.2e-2) === true;
v.isNumber("42") === true;
v.isNumber("42.5") === true;
v.isNumber("0b101010") === true;

v.isNumber(null) === false;
v.isNumber(undefined) === false;
v.isNumber({number : 0}) === false;
v.isNumber([1,2]) === false;
v.isNumber("abc123") === false;
v.isNumber("123.4.5") === false;

isInteger

Realiza las mismas validaciones que isNumber() y adicionalmente solo retorna true si el valor es un número entero. ####Uso

v.isInteger(42) === true;
v.isInteger(42.5) === false;
v.isInteger(42e-3) === false;

isString

Retorna true si el valor es una string.

Arreglos de caracteres, aunque pueden ser considerados como "string", también devuelven falso. ####Uso

v.isString("hola mundo") === true;
v.isString(new String("El veloz murciélago hindú comía feliz cardillo y" +
"kiwi. La cigüeña tocaba el saxofón detrás del palenque de paja")) === true;

v.isString(['H','o','l','a']) === false;
v.isString(null) === false;
v.isString(undefined) === false;
v.isString("") === false;

isEmptyString

Retorna true si y solo si el argumento es una string y está vacía. ####Uso

v.isEmptyString("") === true;

v.isEmptyString(" ") === false;

isBlankString

Retorna true si el argumento es una string que está vacía o solo contiene caracteres de espacio en blanco. ####Uso

v.isBlankString(" ") === true;
v.isBlankString("") === true;
v.isBlankString("\n") === true;
v.isBlankString("\r") === true;
v.isBlankString("\t") === true;

Sanitizers

Here is a list of the sanitizers currently available.

Sanitizer | Description -------------------------------------- | ------------------------------- blacklist(input, chars) | remove characters that appear in the blacklist. The characters are used in a RegExp and so you will need to escape some chars, e.g. blacklist(input, '\\[\\]'). escape(input) | replace <, >, &, ', " and / with HTML entities. unescape(input) | replaces HTML encoded entities with <, >, &, ', " and /. ltrim(input [, chars]) | trim characters from the left-side of the input. normalizeEmail(email [, options]) | canonicalizes an email address. (This doesn't validate that the input is an email, if you want to validate the email use isEmail beforehand)options is an object with the following keys and default values:all_lowercase: true - Transforms the local part (before the @ symbol) of all email addresses to lowercase. Please note that this may violate RFC 5321, which gives providers the possibility to treat the local part of email addresses in a case sensitive way (although in practice most - yet not all - providers don't). The domain part of the email address is always lowercased, as it's case insensitive per RFC 1035.gmail_lowercase: true - GMail addresses are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, GMail addresses are lowercased regardless of the value of this setting.gmail_remove_dots: true: Removes dots from the local part of the email address, as GMail ignores them (e.g. "john.doe" and "johndoe" are considered equal).gmail_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "[email protected]" becomes "[email protected]").gmail_convert_googlemaildotcom: true: Converts addresses with domain @googlemail.com to @gmail.com, as they're equivalent.outlookdotcom_lowercase: true - Outlook.com addresses (including Windows Live and Hotmail) are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, Outlook.com addresses are lowercased regardless of the value of this setting.outlookdotcom_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "[email protected]" becomes "[email protected]").yahoo_lowercase: true - Yahoo Mail addresses are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, Yahoo Mail addresses are lowercased regardless of the value of this setting.yahoo_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "-" sign (e.g. "[email protected]" becomes "[email protected]").icloud_lowercase: true - iCloud addresses (including MobileMe) are known to be case-insensitive, so this switch allows lowercasing them even when all_lowercase is set to false. Please note that when all_lowercase is true, iCloud addresses are lowercased regardless of the value of this setting.icloud_remove_subaddress: true: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "[email protected]" becomes "[email protected]"). rtrim(input [, chars]) | trim characters from the right-side of the input. stripLow(input [, keep_new_lines]) | remove characters with a numerical value < 32 and 127, mostly control characters. If keep_new_lines is true, newline characters are preserved (\n and \r, hex 0xA and 0xD). Unicode-safe in JavaScript. toBoolean(input [, strict]) | convert the input string to a boolean. Everything except for '0', 'false' and '' returns true. In strict mode only '1' and 'true' return true. toDate(input) | convert the input string to a date, or null if the input is not a date. toFloat(input) | convert the input string to a float, or NaN if the input is not a float. toInt(input [, radix]) | convert the input string to an integer, or NaN if the input is not an integer. trim(input [, chars]) | trim characters (whitespace by default) from both sides of the input. whitelist(input, chars) | remove characters that do not appear in the whitelist. The characters are used in a RegExp and so you will need to escape some chars, e.g. whitelist(input, '\\[\\]'). isSlug | Check if the string is of type slug. Options allow a single hyphen between string. e.g. [cn-cn, cn-c-c] ####Uso
